1. A computer implemented decision support method of matching supply and demand between customer forecast demands and semiconductor foundry manufacturing capacity, comprising the steps of:

  • (1) providing Sales Demand Forecast Data, dividing said Sales Demand Forecast Data into categories;

    (i) providing a Minimum Support record;

    (ii) providing a Maximum Support record;

    (2) providing Order Data, creating a Historical Support record or HS, using the Order Data as input to this function;

    (3) using said Minimum Support record and said Maximum Support record and said Historical Support record as input records, dividing said three records into;

    (i) Fully Support Demand record;

    (ii) Initial Condition Demand record; and

    (iii) Expected Support Demand record;

    (4) providing current salable capacity data and future capacity plan data;

    (5) providing Customer Profiling Model data, said Customer Profiling Model data being sub-divided into categories of;

    (i) Customer Ranking;

    (ii) New Super Stars; and

    (iii) Planned or Intended Technologies of a foundry;

    (6) providing a Product Profiling Model record, said Product Profiling Model comprising indexes;

    (i) “

    Hot”

    Products; and

    (ii) Market Trend;

    (7) assigning a weight to each demand, creating future capacity plan data, said weight to each demand being;

    (i) a Fully Support Demand pool;

    (ii) an Initial Condition Demand pool; and

    (iii) an Expected Support Demand pool;

    (8) using a Demand-Supply matching algorithm, dividing submitted demands of Fully Support Demand, Initial Condition Demand pool and Expected Support Demand pool into Supported Demand and Non-supported Demand, said algorithm being an arbiter in deciding which demand will be supported first, whereby the Demand-Supply matching algorithm stops selection or assignment of salable capacity after all salable capacity has been assigned or consumed; and

    (9) combining Supported Demands and Non-Supported Demands, provided by the Demand-Supply matching algorithm, using an Index/Reporting Function, making combined results available to foundry management, thereby monitoring and adjusting of foundry production with orders placed, said monitoring and adjusting being performed by means of input to the customer profiling model and the product profiling model, indexes of the Customer Profiling Model and the Product Profiling Model being adjustable by management.
