假设给定了设施-需求之间的距离矩阵,照着上面的模型即可写出Leapms模型。 //===//The P-Median Problem//===min sum{j=1,...,J;i=1,...,I}h[i]d[i][j]y[i][j] subject to sum{j=1,...,J}y[i][j]=1|i=1,...,I y[i][j]-x[j]<=0|i=1,...,I...

p facilities 我觉得可以理解为P模型 或者可以理解原为的意思为：这类问题最简单的选址办法是p个facilities被选择做为@#$%^&*…… 因为P中值问题之所以被叫做P中值问题 就是其数学模型在建立时 将最终建立的设施节点总数设为p个p-median problem的意思就是P中值问题喽 ...
