碩士 === 朝陽科技大學 === 營建工程系碩士班 === 96 === At the beginning 20 century, RMC (Ready Mixed Concrete) was introduced in the industry of construction at first and widely used. Due to the cement hydrate action, the using of RMC within certain limits by time, they need to consider the immediateness and application when the batch plant dispatcher, also try to dispatch RMC truck to different site; however dispatcher usually deliver by personally experience. In this case, they deliver it always inefficiency and might lose profit. Therefore, how to make sure within a short time if the RMC trucks dispatches to the batch plant exactly according to the schedule time is a vital issue. With development of information science and tech communication technology, GPS (Global Positioning System) have been applied to many fields extensively recent years. For example: vehicle fixed position, vehicle supervision, and measure etc. There we had a research to those RMC trucks has GPS on it, thronging GPRS (General Packet Radio Service) we keep sending information of the position and speed of RMC trucks back to batch plant, Comparing and calculation the historical driving information and those been sent back, we use the information to evaluate the over plus time of driving information and update the historical driving data. This research combines computer simulation technology with the Genetic Algorithms calculation and “Commercial Vehicle Monitor delivery management service system” made by Chunghwa Telecom to developing the Mode of RMC trucks dispatching schedule. The result of this research shows that the dispatching schedule model could update historical driving data immediately to evaluate the future RMC trucks travel time, which makes RMC trucks state of corresponding to reality when commute from batch plant and site. By the assistance dispatching schedule model that can product the efficient and elasticity for RMC trucks dispatching schedule in a short time, besides it can enhance the percentage of using the RMC trucks in order to make the most for company.
