This paper studies the problem of determining the optimal number of workers in each station and the optimal amount of overtime used to meet the workload requirements associated with a given assembly sequence for a just-in-time mixed-model assembly line. The problem is formulated as an integer program which minimizes the sum of the work force adjustment cost and the overtime cost. A polynomial time-bounded algorithm is developed to solve the problem optimally. A numerical example is used to illustrate the procedure of the algorithm.
