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...

Transportation Matrix
I am modeling a production process and want to observe the influences of shipping input products to various production sites. 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...

I have seen one presentation on at least half of your topic which concluded traffic circles are far better at keeping traffic moving and safe rather than the fluctuations in traffic volume and speed caused by stoplights. 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...
