碩士 === 國立中央大學 === 企業管理研究所 === 100 === It was a trend of the world to conserve energy to reduce carbon emission, and more and more important to discuss the green idea of the supply chain management, even the distribution logistics. The companies not only seek the efficiency of the production, but also the environment protection. The outbound logistics is a dimension of the green supply chain management which proposed by Sarkis (1998). It’s probable to achieve the purpose of reducing green cost, by well-designing of the outbound logistics. We usually use many vehicles to transfer goods from site to site in the distribution network. It makes a lot of fuel consumption and carbon emission. To avoid unnecessary waste, the companies perform the Vehicle-Routing Problem (VRP) planning. There are many kinds of VRP planning methods which had been proposed. Most of them are planned base on the distance or time cost, including the Savings Heuristics proposed by Golden et al. (1984). Golden estimated for the variable cost base on the vehicle-traveling distance and considered the fixed cost of the vehicles at the same time. Savings Heuristics can reduce the cost by merging two vehicles again and again, until without any possible improvement. To achieve the purpose of this research, developing a VRP planning base on green cost to reduce the carbon emission, the research will modify the framework of Savings Heuristics and make it can estimate green cost with the speed of the vehicles.
