Various embodiments include computer-implemented methods of modeling production for a semiconductor foundry. One method includes: obtaining a multi-part order including: a first order for a fixed number of preliminary products; and a second order for a fixed number of completed products formed from the fixed number of preliminary products; and determining an amount of inventory required to fulfill the first order and the second order, wherein the determining includes: creating a first model including a first inventory amount required to meet the first order; and creating a second model including a second inventory amount required to meet the second order, wherein the second model accounts for results from the first model, including the first inventory amount; and running a single linear programming (LP) process using the first model and the second model to determine the amount of inventory required to fulfill the first order.

Foundry production planning

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.
