摘要
The critical materials and critical parts are keys to the production at Engineer to Order (ETO) enterprises implies that the control of plans for critical materials and critical parts is essential to the control of all plans at ETO enterprises. A mixed mode of hierarchical network planning/MRP (NP/MRP) is proposed to generate network plans for critical materials or critical parts from project networks and the plans for non critical parts produced by MRP are constrained by the related project networks. The multilevel hierarchical network planning/MRP mixed planning (MHNM) architecture proposed is the extension of the hierarchical NP/MRP to the supply chain based on the temporal constraints of multilevel project networks for critical materials or critical parts. A general model is formulated for scheduling tasks on machines at work centers as well.
