Recalling results from the previous time step

I am looking for a way to recall a variable's solution in the previous time step. My application is to simulate the dynamics when a processing facility looks like they will need to add or drop a shift given the current work volume. The first desire is to import or export work. This desire could be m...

Running a simulation for only one view

I am working on a model with many views, each view with a specific excel lookup table. I would like to make sure I call up the correct excel data for each view by running each view individually and seeing which spreadsheets are opened? Is this possible or is there a better to test for accuracy? than...

The hope is to capture if system wide cost effiencencies can be made and how they effect other important operating parameters. The current issue I am having is weighing the c...

However measuring the well being of a city is another matter as you need to acc...

Time Steps

I am having trouble solving an issue related to time steps. I am mapping a production process where the input data is available on a monthly basis but the processing decisions are made on a daily basis. My problem lies if I use a time step of one month the rates in the system do not react quickly en...
