PLANNING OF COUPLED PRODUCTION IN MULTIPU RPOSE CHEMICAL-PLANT

This article considers strategies for computer-aided planning of coupl ed production for systems of networked multipurpose plant. Reasons are given for the failure of classical strategies such as are used in PPS systems. A procedure is described which, starting from a final produc t, automatically generates a cascade of previous product jobs and assi gns them to production lines along a time axis (simultaneous material, pecursor, and production line assignment planning). Possibilities of interactive improvements of a given solution on consideration of facto rs such as storage costs and turnover are presented.
