Run-Time Interface Example

Suppose you build a factory model and determine the first lathe, Lathe_1, is a bottleneck. The model results indicate the throughput is lower than expected. You decide to perform several what-if scenarios with the model by changing the operation time of Lathe_1. Instead of changing the operation time at Lathe_1 within the Process edit table, it is easier to define a macro with an RTI. This technique allows the model user to easily see the effect of installing a faster lathe without ever editing the model itself. The following example represents the dialog used to define the RTI for the macro where the operation time is a numeric value between 12 and 20:

After defining the RTI for the macro, substitute the macro, Oper_Time, for the operation time in the operation logic in the Process edit table for Lathe_1 as shown below:

You are now able to change the operation time at Lathe_1 using the Model Parameters option in the Simulation menu. For more information on changing model parameters and defining scenarios, see Model Parameters.
