Research On Logistics Distribution Optimization And Track And System Implementation

As we all know, logistics is the Third Profits of enterprise, the seeking for the profits have large space to exploit, which some famous expert put forward Iceberg Theory to describe. Distribution is the essential process of logistics, and the cost of distribution is the important part of logistics cost. We will do research on logistics and distribution from two aspects of how to make distribution plan and how track implement of distribution.First of all, we focus on the problem of making distribution plan, namely the Vehicle Routing Problem or VRP for short. The research on VRP before has too much limiting factor, so it is hard to implement. According to operation flow in fact, we put forward a mode of distribution optimization problem base on layers, then analysing subproblems in mode, constructing mathematic mode and giving algorithm. The research on Vehicle Routing Problem is emphases in the subproblems, so we give a case to prove it.Then, we study distribution tracking problem, and develop new ways to track distribution implement applying GPS/GIS/RFID. First, we construct architecture and management mode of GPS/GIS/RFID to realize the goods and vehicle information flow in a closed loop. Again, we discuss the VRP under this architecture, and do some research on vehicle arrangement problem base on GPS/GIS.In the end of this thesis, according to operation flow of third part logistics enterprise, we give a detail description of design and implementation process of logistics distribution tracking management system.
