In the rapidly evolving landscape of advanced manufacturing, the convergence of Queueing Theory, Digital Inventory, and Risk Management is reshaping the way we approach Additive Manufacturing (AM). This intersection represents a pivotal moment in the industry, where the theoretical meets the practical, and where intelligent systems are poised to revolutionize production processes.

THE BASIS

Cybernetic Vision

Numorpho Cybernetic Systems envisions a future where intelligent process engineering is at the heart of manufacturing. Their approach leverages the principles of cybernetics – the science of communication, command and control in complex systems – to create adaptive, self-regulating manufacturing processes based on feedback. In the context of AM, this translates to systems that can:

1. Optimize production queues in real-time based on current demand, machine capacity, and material availability.
2. Predict and mitigate potential risks before they impact production.
3. Dynamically adjust process parameters to maintain optimal quality and efficiency.

The Digital Inventory Revolution

Complementing this vision is Würth Additive Group’s foray into the Digital Inventory System (DIS). The DIS represents a paradigm shift in inventory management, moving from physical stockpiles to digital repositories of part designs and manufacturing instructions. This approach promises to:

1. Reduce physical inventory costs and storage requirements.
2. Enable on-demand production of parts, potentially at or near the point of need.
3. Facilitate rapid iteration and customization of designs without the need for retooling.

The Synthesis: Intelligent, Risk-Aware Digital Manufacturing

The synthesis of these approaches creates a powerful framework for next-generation AM:

1. Queueing Theory in AM: By applying queueing theory to AM processes, we can optimize the flow of print jobs, balance machine utilization, and minimize idle time. This is crucial in a digital inventory system where parts are produced on-demand.
2. Digital Inventory and Risk Management: The DIS allows for comprehensive risk assessment at the design stage. Each part in the digital inventory can be associated with a risk profile, considering factors like material properties, geometric complexity, and intended use.
3. Cybernetic Control Systems: Intelligent process control systems can continuously monitor the AM process, comparing real-time data against the digital inventory’s “ideal” parameters. Any deviations can trigger immediate adjustments or alert operators.
4. Predictive Maintenance: By analyzing patterns in production data, cybernetic systems can predict potential equipment failures or quality issues before they occur, scheduling maintenance or adjustments proactively.
5. Adaptive Supply Chains: The combination of digital inventory and intelligent queueing can create highly responsive supply chains. Production can be dynamically allocated across a network of AM facilities based on real-time demand and capacity.
6. Continuous Learning: As more parts are produced, the system accumulates data on process outcomes. This data can be used to refine risk models, optimize queue management, and improve part designs in the digital inventory.

This integrated approach promises to deliver a manufacturing ecosystem that is not just efficient and flexible, but also inherently risk-aware and self-optimizing. It represents a significant step toward the realization of Industry 4.0 principles in the AM sector.

As we delve deeper into these topics, we’ll explore how these concepts are being implemented in practice, the challenges that remain, and the potential future developments that could further transform the landscape of additive manufacturing.

THE LADDER OF CAUSATION

The ladder of causation is a three-level model that helps people understand causal relationships:

• Association: The lowest level, where you observe and look for patterns in data. For example, you might notice that people who buy toothpaste are more likely to buy dental floss.
• Intervention: The middle level, where you predict the effects of actions by conducting experiments.
• Counterfactuals: The highest level, where you imagine what would happen if things were different. You can ask “what if” questions at this level.

The ladder of causation has been useful in developing more intelligent AI systems. It’s also a way to approach causality by specifying what types of questions can be answered with a causal model.

Can you elaborate on it a bit more and how we can use Lacan’s registers of Symbolic, Imaginary and Real to build out a platform for process engineering? 

The Ladder of Causation is a three-level model developed by computer scientist Judea Pearl that helps people understand causal relationships. It consists of:

1. Association: Observing patterns in data, such as people who buy toothpaste also buying dental floss.
2. Intervention: Predicting the effects of actions through experiments.
3. Counterfactuals: Imagining different outcomes by asking “what if” questions.

Jacques Lacan’s registers of Symbolic, Imaginary, and Real can be related to the Ladder of Causation for process engineering as follows:

• Symbolic: Representing the system or process using mathematical models, similar to the Association level of the Ladder of Causation.
• Imaginary: Visualizing and understanding the process through simulations, like the Intervention level.
• Real: Optimizing the system by considering “what if” scenarios, akin to the Counterfactuals level.

Integrating Lacan’s registers with the Ladder of Causation can help engineers build a comprehensive platform for process engineering that combines mathematical models, simulations, and optimization techniques to enhance efficiency and performance.

How could it also make AI interfaces less brittle?

Applying the Ladder of Causation and Lacan’s registers to AI interfaces can make them more adaptable and less brittle by enhancing their ability to understand, learn, and respond to complex situations. Here’s how:

1. Improved understanding: By integrating the symbolic, imaginary, and real aspects, AI systems can better understand the underlying processes and their causal relationships. This deeper comprehension leads to more accurate predictions and fewer errors.
2. Enhanced learning: The association, intervention, and counterfactual levels of the Ladder of Causation enable AI systems to learn from data, experiments, and hypothetical scenarios. This continuous learning process helps AI interfaces adapt to changing conditions and become more resilient.
3. Contextual decision-making: Combining the insights from Lacan’s registers and the Ladder of Causation, AI systems can make more context-aware decisions, reducing the risk of brittle responses in unforeseen situations.
4. Proactive problem-solving: AI interfaces can leverage counterfactual reasoning to anticipate potential problems and devise solutions in advance, further reducing brittleness.

Incorporating these concepts into AI interfaces can lead to more robust and adaptable systems that can handle uncertainty, complexity, and change more effectively.

Our onus is to utilize Cybernetics 2.0 – a coordinated relationship between observer and observed that accounts for communication, command and control, and the utilization of feedback mechanisms to re-justify and re-learn for continuous improvement. How could new AI with a basis on the ladder of causation, queueing theory and genAI enable process engineering?

The integration of Cybernetics 2.0 principles, the Ladder of Causation, queueing theory, and generative AI (genAI) can revolutionize process engineering by creating a dynamic and self-improving ecosystem that fosters continuous learning and optimization. Here’s how:

1. Observer-observed relationship: In this context, the AI system serves as the observer, monitoring the process and gathering data. The observed is the process itself, which is influenced by the AI’s interventions based on the insights gained from the Ladder of Causation and queueing theory.
2. Communication and command: The AI system communicates its findings and recommendations to the process engineers, enabling them to make informed decisions. It can also execute commands to adjust the process parameters for optimal performance.
3. Feedback mechanisms: Continuous feedback loops between the AI system, the process, and the process engineers ensure that the system learns and adapts over time. This learning process helps refine the AI’s understanding of causal relationships and queueing dynamics, leading to more effective interventions.
4. Generative AI (genAI): GenAI can generate novel process designs and optimization strategies based on the accumulated knowledge and feedback. This creative aspect helps uncover new possibilities for improving efficiency and performance in process engineering.

By incorporating these concepts, AI systems can become invaluable tools for process engineers, enabling them to optimize processes, reduce waste, and drive continuous improvement in a dynamic and ever-evolving environment. This holistic approach leads to a more resilient, adaptive, and efficient process engineering landscape.

QUEUEING THEORY

• Episode 1 – The Entrepreneur and The Queueing Theorist (polaris-flow-dispatch.com)

Check Dr. Krishna Kumar‘s post on the Entrepreneur and the Queueing Theorist in his blog The Polaris Flow Dispatch.

Part 1 discusses the importance of understanding queuing theory for entrepreneurs to enhance customer satisfaction and improve service delivery.

Queuing theory is a mathematical approach that analyzes waiting lines and delays, helping businesses optimize their operations. Key takeaways from the article include:

• Queuing theory enables entrepreneurs to balance resource allocation and manage waiting lines, ultimately reducing boredom, irritation, and frustration among customers.
• By applying queuing theory, entrepreneurs can enhance their service delivery and create a customer-focused environment.
• Businesses should consider offering little extras to make the queuing process more enjoyable or easier for customers, turning it into a positive part of the overall experience.
• Entrepreneurs should seek opportunities to learn about and apply queuing theory to optimize their operations and provide better service to their customers.

A great definition is within the story:

Queueing is a phenomenon that emerges whenever you have concurrency constraints in your process. It’s often not easy to tell where and when this might emerge. It introduces an element of randomness into even the most deterministic process, especially when you don’t have control over demand.

For us at Numorpho Cybernetic Systems (NUMO), as we enable process engineering in additive manufacturing for custom mass production, understanding and implementing queuing theory can significantly improve customer satisfaction and overall business success for manufacturers across various industries.

By enabling orchestration of all aspects of the process, our Mantra M5 will intelligently concert the activities of make, manage, move, market and maintain to enable operational efficiency and continuous improvements based on feedback using the tenets of cybernetics.

By provisioning new stack MES and MOS systems like Infor, Oqton, Tulip Interfaces and Amper Technologies, and utilizing Würth Additive Group Digital Inventory System (DIS), we intend to provide a seamless interface to enable frictionless manufacturing flow for our clients.

Working in conjunction with UPTIVE Manufacturing and enabling IoT using sensor technologies from Arduino, Sony Semicon | AITRIOS (global) and others we plan to institute smart monitoring on the shop floor to enable safety, operational efficiency and predictive analytics using our CONNECT-DETECT-PROTECT theme.

Here is where our conjunction with organizations like mHUB and MxD will help us evolve our thesis for new engineering and manufacturing that will evolve our solutions for Industry 4.0 and what we call Industry and Services 5.0 using Cybernetics 2.0 processes for communication, command and control to build next generation products and services.

• Episode 2

Correlation is not causation” was the breakthrough in understanding causality that scientist Judea Pearl posited in systematically studying the “Ladder of Causation,” a framework that highlights the distinct roles of seeing, doing, and imagining.

In Episode 2 of The Entrepreneur and The Queueing Theorist, Dr. Krishna Kumar (KK) discusses the causal nature of queueing at
https://lnkd.in/gnawVhJA
in his blog post at the Polaris Flow Dispatch.

KK’s discussion of the causal nature of queueing aligns with Judea Pearl’s Ladder of Causation and the concepts presented in his book, “The Book of Why?” wherein the three levels of understanding causality are:

1. Seeing: Observing associations and correlations between variables.
2. Doing: Experimenting and intervening to observe the effects of actions.
3. Imagining: Counterfactual reasoning and considering hypothetical scenarios.

KK’s exploration of queueing theory emphasizes the importance of causal understanding in managing waiting lines and optimizing service delivery. By employing the principles of queueing theory, entrepreneurs can move beyond merely observing correlations between variables (seeing) and take actions to improve their operations (doing). Furthermore, they can engage in counterfactual reasoning to predict the outcomes of different strategies (imagining).

KK’s discussion highlights the following aspects that align with Pearl’s framework:
1. Observing and understanding the factors that contribute to queue formation and delays (seeing).
2. Experimenting with different strategies and interventions to reduce waiting times and improve customer satisfaction (doing).
3. Imagining the potential outcomes of various queuing systems and configurations, considering counterfactual scenarios, and implementing changes to optimize performance (imagining).

Both Pearl’s “Ladder of Causation” and KK’s exploration of queueing theory emphasize the importance of understanding causality in making informed decisions, enhancing performance, and creating better outcomes in various domains.

For us at Numorpho Cybernetic Systems (NUMO) in building our process engineering platform, the Mantra M5 to coordinate the 5 tasks of make, manage, move, market and maintain, by moving beyond mere correlation and embracing causal reasoning, we can enable businesses to optimize their operations and achieve greater success. This will be especially effective in large infrastructure maintenance projects where understanding the probable cause of failure would be key to enact proactive measures to prevent operational impediment.

As we build our platform based on cognition (perception and intelligence), computation (simulation and generation of synthetic data) and conation (applying inference), these will be key for us the convert meaning to motion – the enablement of actionable intelligence.

Queueing theory contributes by analyzing waiting times, service rates, and queue lengths, which aids in optimizing resource allocation. With a clearer understanding of the factors contributing to delays, businesses can better manage their resources and enhance the flow of work.

Additionally, implementing intelligent queueing theory allows organizations to identify and address bottlenecks in the production process. By adjusting service rates, modifying queue capacities, or reallocating resources, companies can minimize flow blockages and ensure a smooth flow of work throughout the system.

Queueing theory also provides valuable insights into system performance, allowing organizations to anticipate delays and proactively address potential issues. This predictability results in a more stable and efficient production process, ultimately reducing cycle time.

• Episode 3

Can you review Episode 3 of Krishna Kumar’s article on Queueing theory and relate it to custom production in 3D print farms in Additive Manufacturing. Here engineers from Krishna Kumar’s article will be replaced by adding of 3D printers to aid and abet throttling scenarios due to production limit saturation.

Krishna Kumar’s article, “The Entrepreneur and the Queueing Bottleneck,” discusses how entrepreneurs can leverage queueing theory to optimize production and manage bottlenecks. Applying this concept to 3D print farms in additive manufacturing, the addition of more 3D printers can help alleviate throttling scenarios caused by production limit saturation.

Just as adding engineers can increase throughput in the engineering process, introducing more 3D printers to a print farm can enhance production capacity. However, it’s essential to maintain a balance to avoid excessive idle time or increased waiting times. Key considerations include:

• Printer utilization: Monitor printer usage to determine the optimal number of printers needed to meet production demands without causing congestion.
• Print job priority: Implement a queueing system that prioritizes urgent or high-value print jobs to ensure efficient resource allocation.
• Print job batching: Group similar print jobs to minimize setup and switchover times, thus reducing overall production time.
• Printer maintenance: Regular maintenance and monitoring of printer performance can prevent breakdowns and unplanned downtime, ensuring consistent production output.

By incorporating these strategies, 3D print farm managers can effectively apply queueing theory principles to optimize their operations, reduce throttling scenarios, and increase overall efficiency. This approach enables them to meet production demands while maintaining a cost-effective and streamlined workflow.

There are several other nuances when it comes to 3D print farms:
– Not all jobs would be the same size
– Depending on the type of printing, Contract manufacturers fill the build volume with multiple jobs so that there might be a wait time to accumulate enough inputs to run the job
– Printer components would have to undergo preventative maintenance so that operations are optimal.
– Coordinate with other other local print farms (concept of endless aisle in ECommerce)
– Updates in printing technologies to print faster and better (should they buy vs lease the equipment?).

How do you think queueing theory should account for this?

To incorporate these nuances into queueing theory for 3D print farms, consider the following adaptations:

• Variable job sizes: Implement a dynamic scheduling system that considers the size and complexity of each print job. This approach can help optimize printer utilization by grouping jobs with similar sizes or complexities, ensuring that smaller jobs don’t get stuck behind larger ones.
• Accumulation of inputs: Analyze historical data to estimate average wait times for different job types and sizes. Use this information to develop a predictive model that helps anticipate wait times and optimize printer utilization. Additionally, consider implementing a real-time communication system to keep customers informed about their job’s status and expected completion time.
• Preventative maintenance: Incorporate maintenance schedules into the queueing model by allocating specific time slots for maintenance tasks. This helps ensure that printers are always in optimal condition, reducing unplanned downtime and improving overall efficiency.
• Coordination with local print farms: Collaborate with nearby print farms to share resources and optimize production capacity. By creating a network of print farms, you can distribute jobs more efficiently and reduce wait times. Implement a centralized job management system that routes print jobs to the most suitable print farm based on factors like capacity, printer availability, and job requirements.
• Updating printing technologies: Regularly assess the cost-benefit of buying versus leasing equipment, considering factors like maintenance costs, obsolescence risks, and financial constraints. To account for this in queueing theory, factor in the potential impact of new technologies on print job processing times, print quality, and printer reliability. Adjust the queueing model accordingly to reflect these changes and ensure that the print farm continues to operate efficiently.

By incorporating these nuances, queueing theory can better accommodate the unique challenges of 3D print farms and contribute to more effective decision-making and resource allocation.

At: https://numorpho.org/2022/12/22/the-good-the-bad-and-the-ugly/ we have discussed a use case with FastRadius, a Contract Manufacturer in the Additive Manufacturing space where things went badly wrong. How can we shore up against such failures?

Here is Krishna Kumar’s response to the above: One nuance that does not come through in this series is the fact that core queueing theory works even when service time distributions are arbitrary probability distributions.

There are bunch of cases that this example does not cover, mainly because I was trying to emphasize the impact of lead time amplification due to the stochastic effects introduced by queueing even when service times are deterministic.

The basic causal mechanisms still apply when service times are stochastic (different sizes, varying times to complete, varying routes to completion etc.) and even when arrivals/departures distributions are not independent, vary over time, are non-ergodic (averages don’t reflect individual paths to completion) etc.

I’ll introduce those cases in later posts and you’ll see that all the basic causal mechanisms for delays work just the same way, except there are more parameters that impact the outcomes…

Krishna Kumar’s response highlights the flexibility and robustness of queueing theory, emphasizing that it remains effective even when service times are stochastic or follow arbitrary probability distributions. The core principles of queueing theory can handle various complex scenarios, including those with varying job sizes, completion times, and routes.

By incorporating stochastic service times and more intricate parameters, queueing theory can provide a more nuanced understanding of the potential delays and inefficiencies in a system. This adaptability is particularly valuable in real-world applications, such as the additive manufacturing industry, where numerous factors can influence the production process.

As Krishna Kumar mentions, future discussions on queueing theory will likely delve into these additional aspects, showcasing how queueing theory can effectively address the complexities inherent in various manufacturing environments. This will further demonstrate the importance of queueing theory as a powerful tool for optimizing production processes, managing resources, and minimizing delays, ultimately contributing to the overall success of businesses operating in these industries.

Wondering if creating a digital twin to simulate queueing having sticks representing “jobs” and their length representing duration can flow into (input) a factory having numbered engineers/equipment in the ready to receive the jobs and work on them. The jobs are black when defined, red when they are waiting, orange when being processed and green when completed.

Then one would vary the size and the timing of jobs being input into the simulation to determine how saturation affects throttling. Dashboards can then be defined to showcase graphs like you have in your episodes to dynamically showcase conditions (engineer absent, job malfunction, etc.) and enable tweaking of parameters to regulate or troubleshoot scenarios.

Once the model is validated, it could also provide for real time representation of a factory process to enable predictive/proactive analysis when conditions change.

Here is Krishna’s response to this: Yes, the modeling/simulation part of this is basically the domain of discrete/agent based simulation tools as you know. Lots of industrial simulation/visualization tools out there support this – AnyLogic for example, or VSOptima for a simpler but more modern interface.

I mostly use the open source JMT tools for this – very sophisticated, but shitty UI and you have to know queueing theory to use it well (but its free 🙂 )

The challenging steps are (as you allude) the calibration to real-time data, synchronizing models with real time data and learning hidden parameters.

The problem in the software development space (really anything where humans are in the loop) is that the “service time” and “concurrency” cannot be modeled accurately. In the software domain there is a *lot* of model error because of this. I don’t know that anyone has really solved this problem.

There is a lot of talk out there that we could learn these model parameters by comparing model outputs to real time data via a neural network type model, but I don’t know any reliable work that has produced any actual results in this direction. But maybe I am not well enough in the loop to know who’s working on this.

Seems mostly aspirational marketing fluff in my opinion. But this is a key problem to solve…

Your suggestion involves using a digital twin, a virtual replica of the physical system, to simulate queueing systems in real-time. The idea is to represent jobs as sticks with different colors indicating their status and to model engineers/equipment as numbered entities ready to process these jobs. This simulation would enable the observation and analysis of how different parameters, such as job size and timing, affect the system’s performance.

Krishna Kumar agrees that this approach is feasible and mentions various industrial simulation tools that could be used for such a task, like AnyLogic or VSOptima. He also highlights the importance of calibration with real-time data to ensure accurate representation and the need for learning hidden parameters.

However, Krishna points out a challenge in accurately modeling service time and concurrency, particularly when human involvement is required, as in the software development space. While there is ongoing research on employing techniques like neural networks to learn model parameters from real-time data comparisons, he notes that no reliable solutions have emerged yet.

Despite the current limitations, developing an accurate and dynamic digital twin for queueing systems would indeed be valuable for predicting performance, troubleshooting, and optimizing processes in real-time. It remains an important problem to solve for various industries to enhance their overall efficiency and productivity.

Can Deep Learning Surrogates be created out of both modeled data and real time info to predict behavior (what to do) so that a quasi-real time operating system can be instituted to manage processed using the tenet of queueing theory? These are needed in large infrastructure projects like managing solar energy and wind farms that some of our peers are charting to do.

Deep Learning Surrogates offer a promising approach for bridging the gap between modeled data and real-time information, enabling predictive capabilities that can support the development of quasi-real-time operating systems. In the context of queueing theory, these surrogates could help optimize resource allocation and decision-making by identifying patterns and relationships in the data.

For large infrastructure projects like managing solar energy and wind farms, Deep Learning Surrogates could be trained on both historical data and real-time inputs to predict system behavior, anticipate potential bottlenecks, and suggest the most efficient actions to take. This could lead to improved overall performance and better management of resources, as well as reduced downtime and maintenance costs.

A quasi-real-time operating system incorporating these Deep Learning Surrogates would continuously learn and adapt to changing conditions, making it an effective tool for handling the complexities and uncertainties inherent in renewable energy systems. This could also facilitate the integration of other advanced technologies, such as IoT devices and smart sensors, to further enhance monitoring, control, and decision-making processes.

While there are still challenges to be addressed, such as ensuring data quality and refining the accuracy of predictions, the application of Deep Learning Surrogates holds significant potential for transforming the management and optimization of large-scale renewable energy projects.

Krishna Kumar: I think all this is much more feasible with IoT sensor data. 

Me, Nitin Uchil, Founder & CEO of Numorpho Cybernetic Systems: Yes, that is what we are doing as part of our data engineering platform by instituting smart monitoring multi-modal sensor based CONNECT-DETECT-PROTECT protocol that is also used in our helmets.

Krishna Kumar acknowledges the feasibility of using IoT sensor data in conjunction with Deep Learning Surrogates for managing large infrastructure projects like renewable energy systems. IoT sensors can provide real-time data on various aspects of the system, such as energy production, environmental conditions, and equipment status.

Your data engineering platform at Numorpho, incorporating the CONNECT-DETECT-PROTECT protocol used in smart helmets, demonstrates a practical application of IoT sensor data integration. This approach enables real-time monitoring and analysis of the system, facilitating predictive maintenance, improved performance, and enhanced safety measures.

By leveraging IoT sensor data and Deep Learning Surrogates, it is possible to create a quasi-real-time operating system that adheres to queueing theory principles. This system can optimize resource allocation, detect potential issues, and make informed decisions to maximize efficiency and minimize downtime. The continued development and integration of such technologies hold significant promise for the effective management and growth of renewable energy systems and other large-scale infrastructure projects.

By understanding the factors that contribute to delays, companies can better manage their resources, reduce wait times, and enhance the flow of work.
3. Reducing bottlenecks: Implementing intelligent queueing theory enables organizations to identify and address bottlenecks in the production process. By reallocating resources, adjusting service rates, or modifying queue capacities, businesses can minimize flow blockages and ensure a smooth flow of work throughout the system.
4. Enhancing predictability: Queueing theory provides valuable insights into system performance, allowing organizations to anticipate delays and proactively address potential issues. This predictability results in a more stable and efficient production process, ultimately reducing cycle time.
5. Informed decision-making: By combining value stream mapping and queueing theory, organizations can make data-driven decisions to optimize their operations. This leads to continuous improvement, increased efficiency, and better alignment with customer needs.

In summary, integrating value stream mapping and intelligent queueing theory can help organizations reduce churn, delay, and flow blockage, resulting in a more efficient, streamlined, and customer-focused production process.

By integrating value stream mapping and queueing theory, organizations can make data-driven decisions to optimize their operations. This leads to continuous improvement, increased efficiency, and better alignment with customer needs, resulting in a more efficient, streamlined, and customer-focused production process.
