Method and apparatus for scheduling work orders in a manufacturing process
First Claim
1. A method for scheduling a plurality of work orders for manufacturing products in a manufacturing process, each work order including operations to be performed using a plurality of resources and materials, the method comprising:
- obtaining resource availability information and material availability information for the manufacturing process;
obtaining work order information comprising date information for the work order, identity and a sequence of operations to be performed for the work order, resources needed to perform each operation and material requirements information comprising the materials needed to perform each operation and the quantity of each material needed for the operation;
scheduling the operations to be performed for the work order when both the resources and the materials required for a particular operation are concurrently available based upon the work order information; and
providing an assigned resource capacity and the scheduling for each operation.

Abstract
A computerized system is provided for scheduling a plurality of work orders in a manufacturing process. Each work order to be scheduled specifies a set of operations to be performed using a plurality of resources and materials. Data including resource availability information for each resource used in the manufacturing process, material availability information for each material used in the manufacturing process, and work order information is received and stored in a computer. The work order information includes a release date for the work order, a want date for the work order, operations information, and material requirements information. The operations information includes the identity and sequence of operations to be performed for the work order, the identity of the resources needed to perform each operation, a minimum resource capacity needed to perform each operation, and the time needed to perform the operation. The materials information includes the identity of the materials needed to perform each operation and the quantity of each material needed for the operation. Resource capacity and a start date/time and a finish date/time are assigned to each operation based upon the resource availability information, the material availability information, and the work order information. The assigned resource-capacity, the assigned start date/time, and the assigned finish date/time for each operation are displayed on a computer screen in a graphical format.
