| After high development and high profits,the coal industry has gradually fallen into the continuous downturns.In order to maintain their own operation,the coal enterprises have continued to produce,resulting in excessive coal stockpiles accumulated in the whole industry.On the other hand,because the level of the domestic coal enterprises management is different,the average cost per ton of domestic coal has been high compared with the cost of the coal enterprises abroad,and the CIF price of imported coal is lower than the average domestic coal prices,many enterprises have chosen the coal imported from abroad,leading to the China's coal prices fall further.High inventories and low prices directly lead to the continuous loss of Chinese coal enterprises.The production costs of coal enterprises continue to rise,while their overall profitability is falling,and the business risk of coal enterprises increases.In the circumstances,the coal enterprises must change management concept,improve the management quality of enterprises,and reduce the production cost of per ton of coal.The level of the business management depends on the accurate decision-making of safty production and operation,which come from the accurate mastery of the enterprise information about safe production and management.The dispatching center as command organization,which management level is critical.Only by raising the level of management,production efficiency of the coal enterprises can be increased.Therefore,the comprehensive information management of coal enterprises has become an important research direction for coal enterprise dispatch management.Although many coal enterprises are aware of the benefits that informatization can bring to their own development,increase their input gradually and establish some information systems,which cannont working well and the final application effect is not ideal.Based on the comprehensive dispatch management platform of coal mine safety production,firstly,the author study the theory related to the coal mine dispatching management information system at home and abroad,the management informationsystem theory,the information system analysis and design theory,and take the UML and the Object-Oriented unified software development process(UP)theory as the support theory in this paper.Secondly,through field survey and communication with related person in Jia Mei Group dispatching management department,the author find out the problems existing in the production scheudling of the dispatching department and in the process of informatization.At the same time,with the help of the coal business experts,some problems in the scheduling management of Jia Mei Group are summarized.And then,combining with the analysis method of UML and the unified software development process(UP)theory,the author analyzes the demand of the comprehensive dispatching management platform of the safe production in the company.Finally,according to the design and implementation theories of the UML and the Object-Oriented unified software development process(UP)theory,the author designed and implemented the overall structure,database,modules,etc.of Jia Mei Group safety production comprehensive dispatching management platform,and puts forward the future prospect of the platform.The comprehensive dispatching management platform can not only help coal enterprises to improve the efficiency of the dispatching command,but also provides them with decision support information timely and accurately,making the enterprise no longer produce blindly,and achieving the goal of decreasing cost and increasing benefit.In this paper,the study of the coal mine safety production comprehensive dispatching management platform devotes to help coal enterprises improve the efficiency of the scheduling command,ensure the safety of production,and transmit the first-line production information to the leaders timely and accurately,which can provide leaders with support information for polices making. |
