An improved service of carsharing, one-way service enables customers use the vehicles from one station and return to other station. The common issue in one-way carsharing service is that the vehicle stock of each station become imbalance, thus will lead to the less customer satisfaction and less utilization of vehicles. Consequently, the relocation is used by the system to move the appropriate vehicle to high demand station in order to elevate customer satisfaction. This paper will demonstrate the Ant Colony Optimization for relocation in one-way carsharing system based on simulation model. Computational simulation result on commercially operational data of carsharing in South Korea is involved to solve relocation problem in one-way system. The result we have obtained in this study provide a clear insight into the impact of Ant Colony Optimization for relocation problem on utilization of system and high customer satisfaction.

Food quality and safety has attained the considerable attention, because of the consumers increasing health awareness, improved economic standards and lifestyle of modern societies. Thus, it is important for distributors, retailers and consumers to purchase agriculture food products and track that they have come through the legal and safe distribution channels. In this paper we proposed a Centralized EPCIS and Sensor Data Repositories based e-pedigree system for agriculture food products to guarantee the quality, safety and reliability of agriculture food products for final consumers. This system not only assure the authenticity of the agriculture food products but also assure the food quality through environmental information such as temperature and humidity during storage, distribution and transportation for food quality.

Intelligent Food Packaging, Distribution Management System tracks the real-time location and temperature information through the food distribution process and optimizes the supply chain in order to satisfy the consumers who want to purchase high quality food. This system uses RFID, sensor network, temperature-history indicator, smart device, etc. to collect information necessary for management of distribution. To develope system, hardware costs, software costs, and labor expenses should be invested. Furthermore, the effects of system can be calculated quantitatively. The purpose of this study is to analyze the actual cost and benefit of Gyeonggi Agricultural Cooperative Federation’s school meal Kimchi supply chain. Cost-benefit analysis is conducted on the different scenarios, and they differ depending on the depth of interest in traceability of different supply chain participants. As a result of this study, we hope to build an environment that can provide transparent food information to different participants of supply chain, support successful supply chain management, and finally improve all participants’satisfaction.
