Abstract
A system and method are provided for calculating virtual WIP time (“VWIP”) in a multiple-bottleneck, multi-product manufacturing facility. The system and method provide for calculation of one or more bottleneck VWIP values. Each of the bottleneck VWIP values represents the amount of work approaching one of n bottleneck workstations, where n>0. The work approaching the bottleneck workstation comprises at least one of m products, where m>0.
