Manufacturing cost estimation of large processing systems

摘要

All material/process selection decisions are driven at least in part by production cost.In many cases,this cost cannot be expected to follow historical patterns that are derived from traditional accounting data.This is particularly true when departures from traditional design,processing,or materials are under consideration.However,part cost can be approximated as a function of the properties of the process,the part design,the constituent materials,and the local process environment;i.e.,cost is adirect result of the resources consumed by a process.The amount of resources consumed by a process can be modeled by applying the same engineering tool kit useful in all process modeling endeavors.
