Figure 4 - Process (Dis-assembly)

Process Parameter

Required

Description

Name

no

Name of the object

Products

no

Products of the object

Bill of materials

no

BOM of the object

Is value adding

no

Determining whether a process contributes to increasing the value of a product

Number of workers

yes

Number of assigned workers per process

Setup time

yes

Time required for an object to prepare for an upcoming product

Create setup matrix

no

Opens a new view to create a setup matrix

Availability

yes

Reliability (in %) with which an object operates without interference.

Percentage only refers to the working time status (machine is not disturbed during unplanned, paused, waiting or setting-up)

MTTR

yes

Meantime to Repair: Time required to repair a malfunction

Exit strategy

yes

Logic according to which the products leave the object

Available modes:

Cyclic (blocking)

Start at successor 1 (cyclic, non-blocking, each test with start at first successor; corresponds approximately to "overflow control")

First free successor (cyclic, non-blocking, start at last successor + 1)

Lowest occupancy (lowest relative capacitive occupancy; without paused and disturbed parts, weighted by time)

Shift calendar

no

Allocation of working hours and rest periods

Exchange parts

no

true: Parts in the parts list are only exchanged virtually. For each incoming part, the exchange rate is rolled for all defined parts, in addition to the actual cycle time of the incoming product. This additional time requirement is determined or rolled for each product in the parts list. Several products from the parts list can therefore lead to increased time consumption for each incoming product.

false: the incoming part is split into the parts in the parts list. The exchange rate and time for part replacement are ignored in the parts list.

Comment

no

Custom notes and annotations

 

Product Parameter

Required

Description

Product

yes

Product to be processed

Cycle Time

yes

Processing time of the (incoming) main product; this can be extended if necessary if parts are exchanged virtually (mode Exchange parts true and exchange rate and time for part exchange defined)

Scrap rate [%]

yes

Probability (in %) with which products are marked as unusable. Selected products are deleted immediately after processing

A part is either scrap or rework at the end of a machining operation, i.e. a part to be destroyed is not reworked in the station

([percentage good parts +] percentage scrap + percentage rework)

 

 

Bill of materials Parameter

Required

Description

Product

yes

End product after dis-assembly of the incoming main product

A product in the parts list is only the initial product/final product if Exchange parts = false

If Exchange parts = true, then only virtual parts are exchanged -> incoming products = outgoing products

Number of created products (1:N)

yes

Total number of output product produced from one main product

created from product

yes

Main product from which the output products are produced

Transfer quantity

yes

Number of output product packed into one carrier for transport to downstream process

Exchange rate

yes

Probability of virtual exchange of dis-assembly product (product above).

Only used only when exchange of parts option is selected.

With exchange of parts there is virtual exchange happening at the station and the final product would be same as the input product.

E.g. during re-manufacturing process removal of old oil from engine can be considered as virtual exchange, where oil removal is considered to be a virtual exchange apart from disassembling of engine.

Input and Output product are then the same, only the exchange will be registered in the simulation statistics.

Time for part exchange

yes

Time required for the virtual exchange of a dis-assembly product (product above).

Only used only when exchange of parts option is selected. With exchange of parts there is virtual exchange happening at the station and the final product would be same as the input product.

Virtual exchange time is added to the dis-assembly time of the ingoing product.
