This paper presents a novel direct solution approach for fully fuzzy transportation problems in which all of the model parameters as well as decision variables are considered as fuzzy numbers. In detail, a fuzzy decoding procedure based on constrained fuzzy arithmetic operations and a fuzzy ranking technique is first introduced for solution of the problem directly without any fuzzy to crisp transformation...
The transportation problem (TP) is an important supply chain optimization problem in the traffic engineering. This paper maximizes the total profit over a three-tiered distribution system consisting of plants, distribution centers (DCs) and customers. Plants produce multiple products that are shipped to DCs. If a DC is used, then a fixed cost (FC) is charged. The customers are supplied by a single...
The transportation problem (TP) is well known as a basic network problem for it could be extensively applied in many fields. The linear transportation problem (LTP), which is the core and basic model of TP, can be extended to other TP with higher complexity. In the present paper, a new particle swarm optimization algorithm (PSO-TP) whose special structure and operators are different from the classical...
