Location Model and Solution for Inland Ports Based on Green Conception

Green conception should be considered when constructing and operating nodes in logistics chain to establish modern green logistics system.This paper applies the green conception into the location problem of inland ports.Environmental factors such as noise,accidents,crowd and emissions are taken into consideration when formulating generalized cost function.Meanwhile,a bi-level programming location model that can satisfy the cost needs of both decision makers and shippers is established considering the leader-follower relationship between two parties.The upper target is to choose an inland port location to minimize the total cost in the system,and the lower target is to allocate the transportation need of the shippers and to minimize the total cost for them.The genetic algorithm is adopted to solve the model.The empirical study shows the model is effective and the genetic algorithm can generate stable optimal solution.
