System Simulation
| Hi-index | 0.00 |
Three parallel production line configurations are compared by simulation: parallel but independent, dual line without expediting, and a dual line with expediting possible around a failure station. Each facility within a stage draws parts from a common queue in a dual line. Relative performance is studied while varying queue capacity, failure rate, repair rate, and number of stages. The preferability of a dual over independent lines is found to depend upon the degree of expediting possible. Expediting, in turn, depends upon the degree of idle machine capacity built into the work standards.
