This paper investigates some of the theoretical and practical issues for the introduction of Just-in-Time (JIT) techniques into an automotive wire-harness assembly line. Some of the issues explored include the number of production kanbans and the unit load size to be used for every air of subassemblyassembly stations in a production line. An associated probability of stockout for different combinations is also determined. Simulation is used to validate the results obtained through an analytical method and to compare two commonly used strategies: the 'on-line' strategy which uses the subassembly operations adjacent to the assembly stations and the 'off-line' strategy which has the subassembly operation at some distance from the assembly line. Four performance criteria are used to evaluate the strategies: throughput, work-inprocess inventory, lead time, and subassembly equipment utilization.
