题目描述

某地区有m座煤矿，其中第i号矿每年产量为a_i吨，现有火力发电厂一个，每年需用煤b吨，每年运行的固定费用（包括折旧费，不包括煤的运费）为h元，每吨原煤从第i号矿运到原有发电厂的运费为C_i0（i=1，2，…，m）。

<span lang="RU" style="mso-fareast-font-family:

</p>

现规划新建一个发电厂，m座煤矿每年开采的原煤将全部供给这两座发电厂。现有n个备选的厂址。若在第j号备选厂址建新厂，每年运行的固定费用为h_j元。每吨原煤从第i号矿运到j号备选厂址的运费为C_ij（i=1，2，…，m；j=1，2，…，n）。

<span lang="RU" style="mso-fareast-font-family:

</p>

试问：应把新厂厂址选取在何处？m座煤矿开采的原煤应如何分配给两个发电厂，才能使每年的总费用（发电厂运行费用与原煤运费之和）为最小。
