Secondly, in the first phase, this paper solves the inventory supplement sub - problem through integer programming model, using the reduction of vehicle routes as the breakthrough to this problem, divides a whole distribution region into many customer subsets by radius - circle partitioning method, determines the optimal number of vehicle of service distribution region, applies two practice - oriented conclusions to reduce the number of routes on the basis of customer grouping, thus decreases considerably the variable scale of integer programming, and solves the problem through professional software to fix inventory supplement plan in plan period
其次，在第一階段使用整數規劃數學模型來規劃庫存補充計劃子問題，以減少車輛巡迴路線數目為求解該整數規劃的突破口，提出與固定劃分策略（ fpp ）相似的客戶分組思想，通過徑?環切割法把整個配送區域劃分成多個客戶子集，實現客戶分組並確定服務整個配送區域的最佳車輛數目。在客戶分組的基礎上建立了精簡路線的整數模型，然後通過運用兩條基於實際經驗的判斷來進一步減少巡迴路線數目，進而極大地減少了整數規劃的變量規模，並利用專業的求解軟體來求解該整數規劃問題，從而確定計劃期的庫存補充計劃。 -
Voice communications and data transmission made along beijing s expressway removed doubts in people s mind about speed of terminal movement and coverage radius of base station of tdd mode. as a result of the experimentation, the datang group and the siemens company plan to organize a large - scale td scdma field demonstration in the near future. according to technical personnel who participated in the field experimentation, with progress of the experimentation, speed of terminal movement allowed by the system can be raised further
經過在北京高速公路上所做的現場通話和數據傳輸試驗表明： td - scdma終端的移動時速可以達到125km ，基站信號功率覆蓋半徑超過16km ，且通話話音清晰，圖象傳輸穩定，這一試驗結果完全證明td - scdma技術標準完全符合國際電聯（ itu ）對第三代移動通信的要求，消除了人們對于tdd模式在終端移動速度和基站覆蓋半徑的疑慮。
