Discrete Event Simulation
We have a high level of expertise in using discrete event simulation and optimization models in conjunction of each other. We have the experience and knowledge of building, verifying, validating, and deploying industrial strength simulation models with high level of accuracy for our clients. Simulation could be used as an analysis tool for predicting effect of changes to the existing system or as a design tool to predict performance of new system under varying conditions:
Why Simulation Modeling
- It enables the study of and experimentation with the internal interactions of a complex system
- Information, organizational and environmental changes can be simulated and effect of these alterations on the system can be studied
- Knowledge gained in designing a simulation can be used to improve the system
- The model can be useful to trace the variables of importance to the system and how they interact
- Simulation models designed for training allow learning without the cost and disruption of on-the-job learning
- Animation shows a system in simulated operation so that the plan can be visualized
- Modern complex systems are best studied using simulation
- When time-varying (non-stationary) behavior must be examined
- Simulation can be used to experiment with new designs prior to implementation
- Simulation models can be used in conjunction of optimization models to improve decision making in the presence of uncertainty
Steps of a Simulation Study for our Clients
- Needs identification and analysis – commencement meeting
- Data collection
- Data analysis and probability distribution fitting and modeling
- Prepare assumptions document
- Present a structured walk-through of the assumptions document to the key personnel
- Build a valid, credible, and appropriately detailed simulation model of the system
- Verify the simulation model
- Make pilot runs and validate the model against existing system historical data
- Experimental design and analysis of simulation runs and new scenarios
- Document, present and use results
- Training program for client’s engineers
