Solving exclusionary side constrained logistics network by using priority-based GA

Logistics network design is one of the most important fields in supply chain management (SCM). For some real-world applications, it is often that the Transportation Problem (TP) is extended to satisfy several other additional constraints or performed in several stages. There is Transportation Problem with exclusionary side constraints (escTP) proposed by Sun as the example. In this model, the TP is extended to satisfy the additional constraints in which the simultaneous shipment from some pairs of plants are prohibited. The restrictions which this model has are deeply concerned with TP in the real world. In this paper, we consider the exclusionary side constrained Logistics Network (esc-LN). It is the network model which combined two-stage Transportation Problem (tsTP) and escTP. To solve the problem, we used a priority-based Genetic Algorithm (priGA), and introduce the designing method of a delivery course.
