由于定位-车辆路线问题是组合优化问题中一个典型的NP难题，大规模时难以精确求解。
It is difficult to solve in large scale because the LRP is a typical NP-hard problem in combinatorial optimization.
本文运用系统分析的思想和方法，研究了物流系统中的设施定位-配给问题和车辆路线问题的组合优化问题——定位-车辆路线问题。
Using the thought and method of system analysis, the paper researches the location-routing problem (LRP), which integrates the location-allocation problem and the vehicle routing problem.
现今许多实际问题，需要综合考虑上述两种问题，这就形成了定位路线问题（LRP）。
Nowadays many practical problems take both problems into account, it has formed location routing problems (LRP).
随着物流环境的复杂化，物流区域的扩大化，设施定位问题和运输车辆路线安排问题之间的相互影响也越来越大。
With the complicated logistics environment and enlargement of logistics area, the interaction between location allocation problems and vehicle routing problems grow larger.
