1 Logistics Sci-Tech No., (200) XCL To Solve One Kind of istributing Routing roblem with XCL,, (, 20020) YO Yu-hua, YON ang, ZN Zhuo (etro China Shanghai Marketing Compang, Shanghai 20020, China) XCL,, XCL,,,, XCL, ; ; ; ; XCL O22 bstract XCL has extensive use in management science, such as linear programming, transportation problem, distribute problem, network optimization, program management, inventory management, anticipate, queue theory and compute emulate etc. t's a good support to the decision of manager, using XCL to establish and solve models. The choosing and optimization of distribute route is very useful in logistics operation and also very difficult. n this text, we mostly use XCL to solve the problem of routing programming with same start and end point. Key words distributing route; optimizing; describling method; saving method; XCl 0 (Council of Logistics Management),,,,, ;,,, ; (0.) C, (.), () ~, 2 (0.) (0.)
