Processor and operator breakdows causes Flexsim to freeze

adrian_k2 — Wed, 12 Jul 2017 10:02:50 GMT

Hi all,

I have built simply model with operator loading and unloading products from processor.

Next, I have defined random breakdowns for processor and operator in order to model human errors.

After breakdowns coincidence, the model freezes without any error message.

Default exponential distribution was used

Tested in Flexsim 2016 and 2017

Please help

Model - operator and processor with breakdowns

@Adrian K2, How would you describe freeze? The Program Flexsim doesn't react anymore; the model run stopps; the model run goes on, but the items aren't processed anymore.,

Exactly, the model run goes on, but the items aren't processed anymore.,

@Dev-Members, @Matthew Gillespie ,At the runtime 43352.382813 the events of the involved processor, queues and operator stopps, only the timed event of the MTBF/MTTR are listed in the event log.

Before I had changed the Stop ID for on off the 2 MTBF/MTTR objects. That hasn't got any influence. breakdown-combi-proc-op.fsm contains a Basic FR which checks, if the involved objects are going into the state idle for some time. Then the model run stopps. This is the method to find the event time interval to understand when the model freezes.
