摘    要:黑白旅行商问题是经典旅行商问题的推广,在基于SONET技术的光纤网络设计、航线调度等领域具有广泛的应用.已有研究工作集中在无向黑白旅行商问题上.文章研究该问题的更一般形式--有向黑白旅行商问题.首先,给出了有向黑白旅行商问题的混合整数线性规划公式.与目前无向黑白旅行商问题包含指数多个约束的规划公式相比,它仅包含多项式个约束.其次,给出了一种启发式算法.实验表明,该启发式算法能够有效地求解黑白旅行商问题的实例.由于无向黑白旅行商问题是有向黑白旅行商问题的特例,故文中的结论对于求解无向黑白旅行商问题同样有效.

关 键 词:有向黑白旅行商问题  NP-难解  混合整数线性规划  启发式算法  旅行商问题  Traveling  Salesman  Problem  求解  实验  启发式算法  多项式  整数线性规划  约束  指数  公式  混合  更一般形式  无向  工作集  研究  应用  调度  航线  网络设计  光纤

Abstract:The black and white salesman problem(BWTSP) is a generalization of classic traveling salesman problem(TSP) arising from work on the design of telecommunication fiber networks using the SONET technology,the scheduling of airline operation,etc.The existing research work focused on the undirected BWTSP.This paper investigates the more general form of this problem,i.e.the directed BWTSP.First,this paper proposes a mixed integer linear programming(MILP) formulation for the directed BWTSP.Compared to the formulation with exponential number of constraints for the undirected BWTSP,the new one contains polynomial number of constraints only.Furthermore,a heuristics for the directed BWTSP is presented.Experiments indicated that the heuristics could effectively solve instances of the BWTSP.Results of this paper could be also useful for the undirected BWTSP when viewed as a special case of the directed BWTSP.
Keywords:directed black and white traveling salesman problem  NP-hard  mixed integer linear programming  heuristics
