The problem of determining part delivery dates in a low-volume assembly line manufacturing large and costly products is studied. At each workstation a part is assembled to the subassembly. These parts are supplied by external vendors with unreliable delivery schedules. The arrival date of a part is assumed to follow a normal distribution whose mean is to be specified. A dynamic programming approach in combination with a heuristic procedure is used to prescribe the vendor delivery dates for a batch of products. Simulation results show the procedure to be significantly superior to a deterministic approach to the problem. Comparisons are also made with a safety buffer method.
