Transportation Problem (TP) is a well-known basic network model that can be defined as a problem to minimize the total delivery cost. But for some real-world applications, the TP model is often extended to satisfy other additional constraints or is performed in several stages. In addition, traditional TP model is not include the concept of opportunity loss. In traditional TP, customer demand is always satisfied. In the real world, there are many cases where customer demand is not satisfied, and opportunity loss occurs. In this paper, we formulate a two-stage transportation problem with opportunity loss. To solve the problem, we applied Differential Evolution (DE).
