Manufacturing Resource Models IE550 Dr. R. A. Wysk
A Resource Model • Something like a list of things (resources) • Something like an architecture of these things • Some type of capabilities model
Things in a Manufacturing System • Men • Materials • Machines • Money
Men • Agents used to plan and conduct material transformation • Normally used in conjunction with some machine
Material • The entity that gets transformed or gets used in the transformation • Material is usually referred to as product substance, i.e., raw material
Machines • Entities that are used to increase power, precision and direct a material transformation • Many classes of machines • Machines within machines
