Modeling and Simulation Basics
This chapter explains the process for creating a basic process model, running the simulation, andviewing the output reports and graphs. It is designed as a hands-on exercise that can be followed using the software. It contains the step-by-step instructions to help you learn how to: • • • • • Define the Process Flow Define Resource Assignments Enter Process Information Simulate your ProcessModel View the Output Reports

In addition, this chapter answers the following questions: 1. What is aProcess Model? 2. What are the main components of the ProcessModel Modeling Environment? 3. What are the basic objects used in a Process Model? 4. What are connections?

Introduction To Process Modeling

Key Concepts
This section presents the concepts necessary to successfully complete the process for creating a process model, running the simulation, and viewing theoutput reports and graphs. Specifically you need to understand: • • Process Models The Modeling Environment ° Layout Window ° Toolbox ° Simulation Menu ° Properties Dialog ° Gallery ° Shape Palette Objects ° Entities ° Activities ° Resources Connections ° Entity Arrivals ° Entity Routings ° Resource Assignments

“As the (Six Sigma) industry moves forward, simulation tools will be greatlybeneficial in processes that are more difficult to pin down. Processes that are integrated across a variety of departments or business units are a great example...These complex environments almost demand process simulation.”

Process Models
A process model is a flow diagram with associated operational information for simulating a process. A process flowdiagram consists of objects (the graphic shapes in the flowchart) and connections (the lines connecting the graphic shapes). Objects represent the elements of the process while connections depict element relationships. A Properties Dialog displays the operational information for each object and connection.

Key Concepts

The Modeling EnvironmentLayout Window
The layout window for drawing the flow diagram is a scrollable drawing area that is divided into pages. Pages correspond to what you would see if the diagram were printed. You may start the diagram anywhere on the layout although it is usually best to start in the upper left corner. The diagram can be easily moved later if needed.

Toolbox
The Toolbox is the column of buttonsdisplayed on the left side of the layout window. The primary buttons in the toolbox are the pointer button used to select objects, the shape button used to place new shapes on the layout, and the line button used to connect the shapes. The other buttons are for adding text, zooming and changing the line style.

Simulation Menu
The Simulation menu allows you to run the simulation, define scenarios orexperiments, run experiments and set simulation options.

Properties Dialog
The Properties Dialog allows you to define simulation information for each object and connection in the model.

“As Six Sigma is deployed throughout a company, Black Belts face increasingly difficult problems which require advancedapproaches and tools. Delighting the customer is what it’s all about, and that comes from consistent end-to-end process performance. Understanding complex processes, and identifying the optimal way to serve customers and shareholders is where process simulation plays a key role.”
