Application of heuristic search algorithm to transportation and assignment

In operational research, issues of transportation and assignment have extensive application. To construct an appropriate heuristic function is the core of heuristic search algorithm. To solve conventional issues of operational research by using the idea of heuristic function will promote the efficiency of solving. From the angle of heuristic search algorithm, the authors give the details on how to construct heuristic function and how to use it for solving issues of transportation and assignment in operational research.
