Benefits Of Using Simulation Tools In Engineering Projects

Would you test a rocket after launch? Then why wait for hardware to test your firmware? Too many teams treat simulation as optional. A “nice-to-have.” A luxury if you have the time. But here’s the reality: Simulation isn’t just faster. It’s actually safer! It gives you: - Full control over the environment - The ability to replay edge cases - Early signals on regressions and logic flaws - And confidence in your code before it hits the field If you ask me, that’s not just convenience. That’s what I call risk management. Because the alternative is ugly: - Waiting for a sensor to glitch after shipping - Debugging issues you can’t reproduce - Letting your users become your test suite Simulation flips the equation. Instead of chasing field failures, You proactively hunt them before they ever reach the PCB. It’s how serious teams de-risk embedded development.

Analysis of Production Lines by Simple, Fast and Scientific Simulation: Apparently, there is no powerful tool in Lean, TOC, Six Sigma, ERP/MRP, Industry 4.0, Generative AI, etc. for simple, easy, quick and sensible analysis of dynamic nature of production lines which are influenced by numerous factors like average cycle time, variation in cycle time, number of resources available, resource calendars, resource speeds, failures and repairs of resources, rework/rejections, etc. Factory Physics / Operations Science is helpful to some extent in this regard but it is not adequately flexible. In my opinion, discrete event simulation (DES) is a powerful, unique method for thorough analysis of dynamic nature of production lines and the effects of those factors. DES is however largely ignored in production systems even by engineers and managers who have a course on DES in college. DES is usually done in industries by simulation experts using sophisticated simulation packages. DES is still considered as fancy or alien by many factory people and consultants. I would emphatically say that DES can be run for production lines easily, quickly, effortlessly and sensibly using simple, scientific software tools like FlowshopSim which are created exclusively for simulating production lines at a high speed. This DES does not require formal simulation knowledge at all. However, I would not recommend watching time-consuming animation in simulation. For analysis purpose, I would look into output summary and the trace of simulation available in graphical and tabular forms. If any engineer/manager or a Lean consultant wants to witness such production line simulation, I would be happy to run FlowshopSim over web for any specified scenarios of a production line. DES in FlowshopSim will not take more data, time and effort than VSM. It quickly provides a lot of knowledge about the production line to be simulated and is far more effective than #vsm for finding bottlenecks and improvement opportunities on the line. Moreover, it facilitates fast, extensive and reliable what-if analysis of the system. What-if analysis of a stochastic production system is absent in all other methodologies for manufacturing systems. The simple and powerful FlowshopSim leverages the knowledge and experience I gained in simulation and scheduling over more than 40 years (after my PhD) as a researcher, academician and manufacturing consultant. Two days ago, I demonstrated over web simulation of various scenarios of a production line to a senior manufacturing consultant Jean-Pierre Goulet, P. Eng., M. Sc. A. in details for more than an hour. I believe he noticed its power, speed, versatility and simplicity for simulating production lines. Intelligent analysis of a system can make continuous improvement drive more efficient. Let us look for improvement in tools and methodologies also. #factorysimulation #productionline #lean #flow #continousimprovement

I’ve seen bottlenecks destroy production lines—here’s how I would eliminate them before they hit the bottom line Elevating operational efficiency is more than a goal; it’s a strategic imperative for industry leaders. For executives focused on maximizing profitability, Discrete Event Simulation (DES) is a game-changer. Here’s how DES can transform your production line from a complex operation into a streamlined, profit-generating machine. 𝗧𝘂𝗿𝗻𝗶𝗻𝗴 𝗜𝗻𝘀𝗶𝗴𝗵𝘁𝘀 𝗶𝗻𝘁𝗼 𝗔𝗰𝘁𝗶𝗼𝗻𝘀 DES models your production line, accurately representing every process and bottleneck. This isn’t just a digital replica—it’s a decision-making platform. By analyzing scenarios, you can predict outcomes and implement strategies for real-world improvements. 𝗘𝗹𝗶𝗺𝗶𝗻𝗮𝘁𝗶𝗻𝗴 𝗕𝗼𝘁𝘁𝗹𝗲𝗻𝗲𝗰𝗸𝘀 DES pinpoints exactly where your production line slows down. By targeting these areas, you can speed up operations and reduce costs, ensuring resources are fully utilized. 𝗢𝗽𝘁𝗶𝗺𝗶𝘇𝗶𝗻𝗴 𝗥𝗲𝘀𝗼𝘂𝗿𝗰𝗲 𝗔𝗹𝗹𝗼𝗰𝗮𝘁𝗶𝗼𝗻 In manufacturing, resources are often stretched thin. DES tests different resource allocation strategies without disrupting operations, leading to more efficient use and direct cost savings. 𝗕𝗼𝗼𝘀𝘁𝗶𝗻𝗴 𝗧𝗵𝗿𝗼𝘂𝗴𝗵𝗽𝘂𝘁 𝗪𝗶𝘁𝗵𝗼𝘂𝘁 𝗔𝗱𝗱𝗲𝗱 𝗖𝗼𝘀𝘁𝘀 Imagine increasing output without new equipment or expanding your workforce. DES makes this possible by simulating changes in line configuration or scheduling, ensuring maximum efficiency. 𝗧𝗲𝘀𝘁𝗶𝗻𝗴 “𝗪𝗵𝗮𝘁-𝗜𝗳” 𝗦𝗰𝗲𝗻𝗮𝗿𝗶𝗼𝘀 In a constantly evolving landscape, agility is key. DES offers a risk-free environment to test scenarios like introducing new equipment or altering schedules, helping you make informed strategic decisions. 𝗔𝗰𝗵𝗶𝗲𝘃𝗶𝗻𝗴 𝗢𝗽𝘁𝗶𝗺𝗮𝗹 𝗟𝗶𝗻𝗲 𝗕𝗮𝗹𝗮𝗻𝗰𝗶𝗻𝗴 A balanced production line is essential for maintaining efficiency.

In a world where efficiency is key, DES offers the strategic advantage needed to lead with confidence and achieve sustained success. ------------------------------------------------------- Looking to stay ahead in your game? ♻️ Repost and follow Krish Sengottaiyan for valuable insights!

A conversation I overhead recently (names and situation altered) - Two engineers: * Anya: An experienced simulation expert. * Mark: A more traditional, less simulation-focused engineer. Scene: Local Starbucks. Anya and Mark are on a coffee break looking frustrated. Mark: Another massive powertrain recall, Anya. This is getting ridiculous. Fuel pump issues again. It just screams manufacturing quality problems to me. The assembly line must be dropping the ball. Anya: While manufacturing execution is crucial, I think we're still underutilizing a critical tool that could catch many of these "manufacturing" issues long before they hit the production line... simulation. Mark: Simulation? Come on, Anya... that's for the design guys. Great for figuring out if a gear ratio works or if a new piston design can handle the combustion pressures. But preventing a faulty part from the line? That's a hands-on manufacturing problem, not a simulation one. Anya: That's a common misconception Mark. The power of simulation extends far beyond initial design. Manufacturing variations are real and how components interact under operating conditions after assembly with these variations is where issues often hide. Mark: But we have testing for that! We run the powertrains on dynos, put vehicles through rigorous road tests. Anya: And those are essential, but simulation makes testing more effective and predictive. We can use simulation-driven testing to explore a much wider range of conditions and variations than physical tests alone. We can simulate the stresses on components with realistic manufacturing tolerances included, finding potential failure points much earlier. It's about understanding how the design behaves with real-world imperfections. Mark: So you're saying simulation isn't just about the initial design but about predicting problems caused by how things are actually made? Anya: Exactly. It's about a digital thread from concept through manufacturing. By integrating simulation deeper into testing and manufacturing, even using digital twins of our production lines with real-time data we can predict potential defects influenced by manufacturing variables before they cause mass recalls. Relying only on late-stage testing is just too late. Mark: Hmm. I… I hadn't really thought about it that way. It's a much more integrated approach than I imagined. Anya: It is. And it's key to moving from reactive to predictive quality saving us significant costs and protecting our reputation.
