Optimising parameter to control production of surplus parts
The objective of overproduction is to get a lower cost solution by producing more (or less) than the required quantity of a part.
It is only useful where production quantities are relatively large and any parts that are overproduced can be used. For example, where the part can be used as stock or can be used to replace damaged items.
The optimisers only use over (or under) production where this produces a lower cost solution and no other parts (with a required quantity) could be used instead. There are two ways of entering overproduction at the part list.
- Enter a tolerance on the quantity required in the overs (or unders) column
- Enter common parts as plus parts, in the cutting list
Common parts have no fixed requirement and can be produced for stock.
Allowing a tolerance on the required quantities usually gives the optimisers more scope and they can produce lower cost solutions.
Part list - at the part list set the overall level of overs or unders and include common parts in the list
Use the Optimising parameter:Value of Plus parts to encourage or discourage the use of plus parts
