HEAD OF LOGISTICS AND SUPPLY CHAIN SYSTEM ENGINEERING RESEARCH UNIT, SIIT, TU

GD.FINDI CONCEPTS

Objective:

This section is to learn how to simulate and run Ham sandwich production process. 1. Create “Floor Plan Layout” and “Station”.

2. Create “Process Plan”.

3. Assign properties for station and process.

4. Link process to station.

5. Add buffer size.

6. Assign station activity.

7. Using EasyGO Function to run the model.
