Playing Puppeteer: Simulation versus Modeling in Business Processes

Welcome to the intriguing world of process simulation! Often mistaken as the evil twin of modeling, simulation is more like a puppet controlled by the puppeteer that is modeling. In the hands of a skilled puppeteer (i.e., a model), a simulation dances through time, reenacting scenes from the past (for the no-nonsense task of validation) or donning the turban of a fortune teller to predict what lies ahead (for the thrilling what-if experiments). It’s like ordering a la carte from a menu where the model is the chef, preparing different dishes, also known as simulations, each seasoned differently.

So, what is this puppeteer (a.k.a. process model) exactly? Think of it as a digital doppelgänger of a real-world process, say, manufacturing or its equally compelling cousins like material hoarding/warehousing, batch documentation, and quality testing laboratories. The process model steps into the spotlight when playing around with the real process is either too extravagant, too disruptive, or because it’s akin to catching a cloud; the process doesn’t even exist yet! In any case, this digital doppelgänger flexes its muscles, conducts all sorts of experiments or ‘what-if’ scenarios, and deepens your understanding of the system, usually while on a mission to cut costs or pump-up productivity.

An added feather in the cap for digital models is their uncanny knack for untangling a system that’s as complicated as a Sherlock Holmes plot. A well-dressed model captures the crux while casually tossing away unnecessary frills. And if the scene involves variability, well, bring it on! The model includes it to paint a more believable picture.

The Process Prowess: Boons of Simulation in Manufacturing

So, armed with this knowledge about process modeling and simulation, what do we stand to gain? Well, the perks are as varied as the situations in which a model is created and used:

Early Bird Special: When a facility is in its infancy and design is underway, it’s best to let simulation take the lead as soon as possible. Any changes inspired by simulation results are cheaper when the design is still on the drawing board.

Home Improvement: If a facility is already up and running but needs a bit of a facelift, the goals might be to boost output, trim manufacturing costs, reduce inventories, or a bit of everything. The improvements that simulation suggests could involve equipment upgrades or sometimes just a tweak in the operating protocols or product scheduling.

Now, whether you’re designing a new facility or renovating an existing one, process modeling can wield its magic wand. For a new design, it can give an accurate estimate of necessary processing equipment, point out potential bottlenecks, and ensure smooth production. And remember, design changes are like London’s weather, unpredictable. But worry not, because a process model can adapt, helping maintain cost-effectiveness and desired throughput.

As for renovating an existing facility, a model can be just as handy. It uses historical data to better itself and the results are likely to be more operationally oriented. Potential changes might be scaled down if the facility space is fixed, leading to unique manufacturing challenges. Models in such scenarios tend to be more detailed and lifelike, requiring more effort to create, validate, and use.

At the end of the day, a well-crafted, validated process model is like a trusty compass, guiding you through alternatives and justifying their costs. These advantages are as applicable to a new facility in the design phase as they are to an existing one in need of a makeover. And if every facility has its own up-to-date model, swift, sound decisions are just a simulation away.
