Abstract: In this paper, we address the composite sourcing policy of a single production facility where customer|s order quantity can be made internally as well as externally. The surplus production capacity within a common production cycle can be utilised for in-sourcing of demand of other suppliers. We regard the traditional economics lot scheduling problem as a capacity allocation problem. Therefore, the decision problem is to determine the lot sizes as well as the composite sourcing policy for three production modes such as out-sourcing, in-sourcing and in-house making. We develop the mathematical model of the resulting decision problem and propose the solution procedure to determine the economic operating policy.
