MANUFACTURING SCHEDULE OPTIMIZATION
First Claim
1. A computer-implemented method for scheduling a manufacturing process for manufacturing a plurality of items, the method comprising:
- a. determining costs associated with switching the manufacturing process between different items;
b. determining a set of costs associated with an inventory level for each item deviating outside predefined parameters associated with a demand forecast;
c. determining a set of costs associated with a customer order being delivered outside of a delivery date;
d. determining a set of production costs;
e. determining a set of all possible manufacturing schedules for the combination of products to meet customer demand and the demand forecasts;
f. for each schedule determining a cost;
g. selecting a schedule which acceptably minimises the determined cost.

Abstract
The invention provides a computer-implemented method for scheduling a manufacturing process for manufacturing a plurality of items, the method comprising: determining costs associated with switching the manufacturing process between different items; determining a set of costs associated with an inventory level for each item deviating outside predefined parameters associated with a demand forecast; determining a set of costs associated with a customer order being delivered outside of a delivery date; determining a set of production costs; determining a set of all possible manufacturing schedules for the combination of products to meet customer demand and the demand forecasts; for each schedule determining a cost; selecting a schedule which acceptably minimises or reduces the determined cost.

31. A system for scheduling a manufacturing process for manufacturing a plurality of items, the system comprising:
-
a. a determinator for determining costs associated with switching the manufacturing process between different items; b. a determinator for determining a set of costs associated with an inventory level for each item deviating outside predefined parameters associated with a demand forecast; c. a determinator for determining a set of costs associated with a customer order being delivered outside of a delivery date; d. a determinator for determining a set of production costs; e. a processor for determining a set of all possible manufacturing schedules for the combination of products to meet customer demand and the demand forecasts; f. wherein for each schedule the processor determines a cost; g. and wherein the processor selects the schedule associated with the minimum determined cost. - View Dependent Claims (32)
