The Research On Express Delivery Vehicle Scheduling Model

With the rapid development of world economy and modern technology, logistics industry as one of the most important service industry in national economy is growing quickly all over the world. It is the fundamental industry of national economy. Delivery is the main part of the logistics and grows an independent business.With the development of economic, there are many cargos which are expressed. They need to be delivered to the destination. In order to get profit and fit for the need of market, the logistics business has to supply the logistics service.With logistics providers standing point, the paper use economic cost to measure the behavior of logistics and distribution; Article made a distinction with "time window" in concept and in the current study, the express service is defined as the volume per unit time of transportation and delivery of customer numbers.According to the views of engineering system, the article analyzes the meaning and types of logistics distribution and designs the system. The article establishes the configuration standards of the logistics to make sure whether the produce is the best. The cost Module also is divided.The article establishes two models in small batches of goods which can be applied to the one-way cargo distribution. These two models are applied to the situations which the customer limits the time to finish unloading the goods and the time to deliver goods. With genetic algorithm and simulation software, the models are validated.
