Hello Everyone,

 

In my model, there is only one workplace(for In-product and Out-product) assigned for all stations. But problem is whenever some worker(with In-product) already occupird workplace and that time Out-product complete their processing time and they call worker(Exit strategy--Carry part away),then its create problem of "station does not have a free workplace" and stopped simulation. How can i solve this problem?

1.) add a second workplace
2.) wait if you transport a part to a station, until this station is empty

Hello sir,

Thanks for your reply.

i can not use waituntil statement because in my Masterthesis model all product distributed from Buffer(FIFO strategy) to other station (according to resource plan table-Different for all product).

Now, Buffer has series of 100 product(A,B,c...). If next station for Product A is not free then it will wait on Buffer.So all product which stand behind A are waiting there but next station for other product is free.Its loss of effeciency.

Other constarin, i can not move Product A to other Buffer2 and wait there until next station is free.

Can you suggest any other concept?

 

For workplace: Can we assign 1 workplace only for In parts other workplace for exit part?

Thanks in advance
