Description
Simulation modeling is a dynamic tool that models the behavior of a process over a period of time. It can show how random variation affects intricate, time-based events and resources.
Uses
For defining requirements.
To test a process without the need to actually perform the process.
How do I use this tool?
1. WALK THROUGH THE ENTIRE PROCESS.
2. CREATE A MAP OF MICROSYSTEM LEVEL processes and their relationship to macrosystem.
3. OBTAIN REAL TIME OR HISTORICAL DATA.
4. IDENTIFY WHICH DESCRIPTIVE STATISTICAL ELEMENTS NEED TO BE COLLECTED.
5. SELECT THE MODELING SOFTWARE.
6. BUILD THE MODEL using performance measures, process flows, and floor plans.
7. VALIDATE - the team should verify that the data and process pieces are valid.
8. DEVELOP BASELINE MODEL.
9. RUN MULTIPLE WHAT-IF SCENARIOS for data generation.
10. MAKE OPERATIONAL DECISIONS for implementing proposed changes.
Expertise Required
This tool is an advanced tool and requires formal training or education.
Recommended Supplies/Materials
Simulation software
Advantages
Allows you to evaluate what the impact of potential changes might be before they are actually implemented.
Models all components moving through a system.
Provides a quick way to run months or even years of related data.
Simulates at nearly any level of detail.
Disadvantages
Can require expensive, complex simulation software.
Is time intensive.
Bad inputs yield poor output.
Offers just a simulation.
A unique set of skills is usually required for this analysis.
