and represented as a point on a transportation network. The problem addressed is to determine an equilibrium price in each … region so that regional price differences do not exceed unit transportation costs, and when trade takes place between two … regions, prices differ by the associated transportation cost. The problem has several quadratic programming formulations. We …

In a transportation problem, generally, a single criterion of minimizing the total cost is considered. But in certain …, consumption of certain scarce resources such as energy, total deterioration of goods during transportation, etc. Clearly, this … bicriteria transportation problem, it is applicable to any bicriteria linear program in general. The bottleneck criterion …

frequencies is available, in such a way that the sum of the transportation and inventory costs is minimized. This problem, which … is known to be NP-hard, has applications in transportation planning and in location analysis. In this paper we derive …

For this purpose, we study the cost effectiveness of restricting the inventory … inventory and transportation cost is no more than 4/3 (5.6/4.6 if transportation costs are stationary) times the optimal cost …
