When a customer has more choices to choose, would a customer only choose one supplier or choose both suppliers? In this research, we assume the production yield rates of the suppliers are random variables, and the assembly firm needs to decide the order quantity. We consider the uncertain yield rates of the suppliers and the trade-off between shortage cost and salvage cost. We propose a single period model to determine the optimal order quantity of the assembly firm where the assembly firm minimizes its own cost. Then we find the condition that the assembly firm only orders from one supplier or two suppliers. Finally, we demonstrate our results by a numerical case and conduct the parameter analysis to observe how parameters affect the assembly firm’s decision.
