in most of the real-life applications we deal with the problem of transporting some special fruits, as banana, which has particular production and distribution processes. in this paper we restrict our attention to formulating and solving a new bi-criterion problem on a network in which in addition to minimizing the traversing costs, admissibility of the quality level of fruits is a main objecti...

This paper deals with the fundamental problem of estimating the distribution function (df) of the duration of the longest path in the stochastic activity network such as PERT network. First a technique is introduced to reduce variance in Conditional Monte Carlo Sampling (CMCS). Second, based on this technique a new procedure is developed for CMCS. Third, a combined approach of simulation and ap...

the existing works considering the flow-based discount factor in the hub and spoke problems, assume that increasing the amount of flow passing through each edge of network continuously decreases the unit flow transportation cost. although a higher volume of flow allows for using wider links and consequently cheaper transportation, but the unit of flow enjoys more discounts, quite like replacing...

determination of shipment quantity and distribution problem is an important subject in today’s business. this paper describes the inventory/distribution network design. the system addresses a class of distribution network design problem, which is characterized by multiple products family, multiple warehouses and retail-ers. the maximum capacity of vehicles and warehouses are also known. the res...

Abstract: The paper develops a multi-objective planning framework for distribution network expansion with electric vehicle charging stations. Charging loads are modeled in the first place, and then integrated into the optimal distribution network expansion planning. The formulation is extended from the single objective of the economic cost minimization into three objectives with the additional ...

The continuous network design problem (CNDP) is known to be difficult to solve due to the property of non-convexity and nonlinearity. Such kind of CNDP can be formulated as a bi-level programme, which may be classified into Stackelberg approach and Nash one according to the relationship between the upper level and the lower level parts. This paper formulates the CNDP for road expansion based on...

We propose a profit maximization model for the decision support system of a firm that wishes to establish or rationalize a multinational manufacturing and distribution network to produce and deliver finished goods from sources to consumers. The model simultaneously evaluates all traditional location factors in a manufacturing and distribution network design problem and sets intra-firm transfer ...
