The library consists of a top-level SimEvents library called


eight sub-libraries:

1. se4_batching.slx,
2. se4_conveyor.slx,
3. se4_math.slx,
4. se4_utilities.slx,
5. se4_DateTime.slx,
6. se4_subsystem.slx
7. se4_examples.slx,
8. se4_test.slx,

five test bench models:

1. test_accumulate.slx,
2. test_batching.slx,
3. test_conveyor.slx,
4. test_DateTime_days.slx, and
5. test_DateTime_minutes.slx.

and three example models:

1. Goldratt_Dice.slx
2. Job_Shop.slx
3. Reorder_Point.slx

I am trying to create a model of a paralell car storage in an automotive factory and I don' t know how to apply a technical availability to each server. I add the cycle time or servcie time for each car but I would like to ass the TAV to simulate breakdowns causing a reduction of the number of entities served. If there any example for this kind of models to help me?

Simple example should be how to create a production line with and automation. This automation will have a cycle time per car and suddnely a breakdwon could occur. How it is modeled?

Many thanks.

I am currently evaluating SimEvents R2016b.

I have no plans at this time to update this content to the new SimEvents (R2016a). I will re-evaluate this decision after MathWorks releases R2016b.

Is there a chance you will update this for the new simevents (2016A)? I would love to use this functionality in a project.

Nice work my friend! You might consider a version that releases the batch as individual entities instead of combined (or make it an option in the mask). You also could eliminate the need for the Time-Based Entity Generator upstream if you had a dialog option that specified the frequency of batching.
