Abstract


The coal industry in China 's national economy plays a decisive role , but as a traditional industry has long been planned economy, coal enterprise management level , especially in logistics management needs to be improved . Modern Logistics and logistics simulation technology to improve the level of logistics management of coal enterprises , the opening of \Firstly, the theoretical aspects of coal mine production logistics system is studied through the production and logistics systems and manufacturing a comparative analysis of the value found in the implementation, logistics and operational characteristics , logistics environment , logistics , logistics, form, manner and logistics means there exists significant differences , highlighting the logistics in coal production in the leading role ; went on mine production logistics process systems were analyzed , focusing on the coal mine production logistics system and its operation process of the main equipment for the next lay the foundation for modeling and simulation ; followed by discrete event modeling and simulation studies related theories proposed coal mine production logistics is the thesis of discrete event systems , comparative analysis of several of today's popular discrete event modeling and simulation software, and WITNESS simulation software to the system introduced ; study on the basis of the above combination of queuing theory , this structure of coal mine production logistics system, computer models , and according to the logical relationship between each device on the shearer cutting coal system , moving rack system , conveyor systems and rail coal transportation system carried out a detailed analysis of discourse , the question of how to discretize continuous haulage system and how discrete continuous coal flow modeling and simulation programs ; then combine theoretical study of how to use the bottleneck WITNESS simulation methods to identify and diagnose bottlenecks in production logistics and set the corresponding evaluation index ; combination of these theories, this paper, a modular object-oriented modeling ideas and establish WITNESS software -based simulation model of coal mine production logistics , and finally this article for typical cases are analyzed and evaluated.
