maximize

Firstly,some interrelated conceptions of transportation problem are proposed,in which,the multiple optimal solutions is expanded to broad-sense category,the narrow-sense multiple optimal solutions and the broad-sense multiple optimal solutions are proposed and differentiated.

首先给出了运输问题最优解的相关概念,将最优解扩展到广义范畴,提出狭义多重最优解和广义多重最优解的概念及其区别。

Based on dissertating the study of transportation problem,some concepts were proposed such as the multiple optimal solutions,the numbered multiple optimal solutions,the unnumbered multiple optimal solutions, the narrow-sense multiple optimal solutions and the broad-sense multiple optimal solutions etc.

在对运输问题研究成果综述的基础之上,归纳出了多重最优解、有限多重最优解、无限多重最优解、狭义多重最优解以及广义多重最优解等概念。
