Abstract:
A method for addressing high Work In Process (WIP) conditions for increasing throughput while minimizing risk in a manufacturing line. Selected products to be skipped over during high WIP conditions include determining toolsets having work in process exceeding a certain threshold. For each of the toolsets, products which meet a criteria for skipping are selected. The selected products skip over to the toolset used in a subsequent process step ahead of product failing to meet the criteria for skipping. Solutions to this problem also include the WIP of the current process step, nominal WIP and WIP of subsequent process steps. Candidate lots for skipping process steps are identified by referencing a matrix of parameters that includes yield and criticality.
