This paper gives a review of the features of Bilevel Linear Programming (BLP) by presenting prior results as well as providing new results, including the capability of the problem to formulate any piecewise linear function and its connection to other optimization problems. The paper also surveys the applications and the algorithms of BLP; the NP-hardness of(More)
This paper presents and discusses the parcel distribution network design problem for ground shipments. An optimization model is developed to formulate this problem. The model is distinguished by its ability to: (i) incorporate actual economies of scale rather than relying on the theoretical discount factor commonly used in the literature, (ii) deal with(More)
