Feb 08, 1996  A general mathematical formulation for multiple campaign planning/scheduling of multipurpose batch/semicontinuous plants is presented. In contrast to sequential approaches, a single-level formulation is developed encompassing both overall planning considerations pertaining to the campaign structure and scheduling constraints describing the detailed operation of the plant during each campaign.
