Foundry production planning

A system comprising:

• at least one computing device configured to model production for a semiconductor foundry by performing actions including:
• 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;
• 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.

A computer program product comprising program code stored on a computer readable storage medium, which when executed by at least one computing device, causes the at least one computing device to perform a method of modeling production for a semiconductor foundry, the method including:

• 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;
• 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.
