Abstract

An animated simulation is used to evaluate two workforce management options in response to work stoppages in an electronic assembly workcell. An industrial based workcell consisting of 15 workstations is modeled in the SIMPLE_1 environment. A work stoppage is introduced at a station and the throughput time for each assembly is recorded. Two strategies are compared: one has five worker groups, each serving a set of stations, and the other allows workers to move between groups. Steady state performance under each strategy is identical, but they differ dramatically in the ability to restore throughput time to its pre-stoppage values. The results quantitatively show a benefit of cross-trained workers.
