Techniques are presented for rescheduling manufacturing releases. A plurality of release information elements are identified based on a first run of a first advanced planning system. The release information elements comprise dates of planned manufacturing release and quantity. The plurality of release information elements are sorted based on associated demand-likelihood factors and a plurality of sorting criteria. Swapping candidates are selected and swaps are performed based on the demand-likelihood factors and at least one swapping constraint. The plurality of release information elements are then fixed and output as results. A second run of an advanced planning system is optionally performed before output and may include stability features.

Systems and methods of adjusting the order of product manufacturing and rescheduling release dates

Method, system and program product for planning production for complementary demands are disclosed. In one embodiment, a method includes obtaining complementary demand values including at least one daily going rate (DGR) demand and a service demand; running a first planning production model in which the at least one DGR demand is included and the service demand is excluded; and running a second planning production model in which DGR related variables are fixed to values determined in the first planning production model and the service demand is included. Demands that are only considered by one of the planning production models are considered complementary demands.

Planning production for complementary demands

The invention provides a method and system for determining a production plan that includes a first step that determines the minimum number of manufacturing starts that are required to meet contractual obligations; and a second step which determines a production plan satisfying the minimum manufacturing starts together with other customer demands. More specifically, the invention presents a method of allocating production starts (e.g., wafer starts) in a manufacturing facility (e.g., wafer foundry) using a linear programming production planning system which performs a first stage of linear programming to satisfy only contractually mandated minimum production starts constraints followed by a second stage of linear programming to satisfy the additional constraints, once the minimum starts constraints are satisfied.
