Transportation transshipment and assignment problems

An introduction to the basic transportation problem and its linear programming formulation: transportation network model objective function constraints. Chapter 6 (transportation, transshipment, and assignment problems) transshipment, transportation, and assignment are part of a larger group known as network flow problems o transportation- items are allocated from sources to destinations at a minimum cost o each source has a fixed supply and each destination has a fixed demand o balanced. The assignment problem is a special case of the transportation problem, and the transportation problem is a special case of a linear programming problem both assignment and transportation problems may be solved using lpp methods, like the simplex method, although there are more specific methods for these problems, as mentioned in other replies.

In this video we could understand easily the transportation problems in or, i have given a problem with northwest corner cell method, least cost cell method and vogel's approximation method. 1 transshipment problem is also a subset of transportation problems but with certain differences following are some of the differences between the two: a)in a transportation problem, shipments are allowed only between source and destination while in a transshipment problem shipment,there exist points through which units of a product are transshipped from a source to a destination b. Transportation, assignment, and transshipment problems in this chapter, we discuss three special types of linear programming problems: transporta-tion, assignment, and transshipment each of these can be solved by the simplex algorithm, a transportation problem is specified by the supply, the demand, and the shipping.

Transshipment problems form a subgroup of transportation problems, where transshipment is allowed in transshipment, transportation may or must go through intermediate nodes, possibly changing modes of transport the transshipment problem has its origins in medieval times when trading started to become a mass phenomenon obtaining the minimum-cost route had been the main priority. Assignment problem is a special type of linear programming problem which deals with the allocation of the various resources to the various activities on one to one basis it does it in such a way that the cost or time involved in the process is minimum and profit or sale is maximum.
