different actions for one server

[mroland]

Hello,

I have an entity going through different steps of fabrication:

1- Cutting

2- Molding A

3- Cure A

4- Demoulding A

5- Molding B

6- Cure B

7- Demoulding B

(The molding operation A is different in time than operation B etc.)

Once the 7 operations finished, a new entity is launched in the system.

There are only 4 machines ( cutting, molding, cure, demoulding)

My question is about the way to use the same machine (represented in my model by a server) for two different operations (A than B)

Thank you for your help

You can use sequence table for the different entities. and store the individual processing time in the table. and refer to it.

okay thank you,

Look at the SimBit SelectEntityTypeFromTable for a simple example.

Look at example RPsixample for a more comprehensive example.

Thank you for your help, my problem is solved now.

I have an other question ,

I'm wondering about the best way to imitate an intermediate stock.

Between my cutting operation and the MoldingA I have a stock where entities are waiting.

A new entity is release from the stock when the previous one has finished the process.

For the moment I'm using a server to show the "stock step" but I don't know how to imitate a real one....

There are many ways to do this depending on the details.

The SimBit OverflowWIP illustrates one approach using secondary resources.

Or you could do something with events as illustrated in SimBit RegeneratingCombiner.

Possibly the easiest is to represent the Stock as a 0 processing time Server with an infinite output buffer, and have a connector (or path with capacity 1) to MoldingA. MoldingA might have a 0 capacity input buffer. So each time a part leaves MoldingA, another part would leave the Stock to take its place.

I will try these solutions, thank you
