abstract

  • Simulation presents a way to analyze the performance of a system with zone capacity constraints, operator constraints, and precedence constraints in an assembly line using takt analysis. A small-scale model of an aircraft assembly line is built in Simio and precedence constraints are modified in independent simulations. The primary performance metric is traveled work, for which a definition is given. A method of calculating traveled work is presented, as well as an interpretation that states the effect on throughput. These results show that, ceteris paribus, traveled work increases flowtime, which decreases throughput. Modifications to the system are suggested that can reduce traveled work.
