摘要
一、前言 在集中供热工程中,供热路线是有向树,不同的供热方案即供热路线就构成了一个含有圈的连通图。从连通图中求最小方向树时,若连通图中每条边的权确定,图论学给出了有效的算法,避圈法和拆圈法。但对于供热方案的连通图,每条边的权却不定,仅当供热路线确定之后,相应边的权才可以算出。这是因为每条边的权与供热量及流向。
In the engineering of the concentration supply heat, heat source supplies thermoenergy to many users. It is a technical and economic problem to select a path of transmission thermoenergy from a given connected graph with cycles and uncertain weight, which meets technical demand and is optimum economics. This paper researches into the problem and the method to solve the problem with establishment of the relevent mathematics model is presented, a example to apply the method reveals that thermoeconomic optimization of the plan of supply heat is obvious to effectively save energy and cost.
