Research And Implementation Of Workflow Scheduling System Face To Pharmaceutical Enterprise

In this paper, we research mainly on a specific production process of flow line production of drug in some pharmaceutical factory which is based on pharmaceutical technology.Afer the base of deeply studying about pharmaceutical technology and control requirement,in the light of a series of questions existing in present production scheduling management,we systemative researched on a series of problems on theoretical and application such as dynamic water extraction, alcohol precipitation,filtration,evaporation,spray drying and so on.In order to realize optimum control of the whole process of pharmaceutical production,we put forward the ideas and principles on design operating control system for pharmaceutical process, and what is more,details of the job shop scheduling(JSP) module of functional modules of the MES and the ERP system was studied.The main work of the thesis are summarized as follows:(1) Aiming at problems of the MES information of the pharmaceutical process and the upper process ERP quality checking and production scheduling information being difficult to obtain the optimal goal commonly,we studied in Job-shop scheduling module between manufacturing execution system(Manufacturing Execution System, MES) and enterprise resource planning(Enterprise Resource, Planning, ERP).As the core module of the cross of MES and ERP,JSP is directly related to the business enterprise management, production and management efficiency, and effective scheduling can reduce production cost, improve the competitiveness of pharmaceutical manufacturing enterprises.(2)In view of the traditional job shop scheduling algorithm long running time and huge computational complexity of the shortcomings,this paper puts forward three kinds of optimization scheduling algorithm,respectively using relative time algorithm which is called RT, heft particle swarm optimization algorithm which is called HPSO-JSP,and the relative weight remaining duration scheduling algorithm which is called WRT,to research on pharmaceutical production scheduling,to optimize the dispatching operation,algorithm of the mathematical model, algorithm, algorithm flow chart and example verification are respectively given.Finally, the WRT algorithm was inserted in the programming MES and ERP system as a plug-in components by some pharmaceutical company to solve the pharmaceutical workshop scheduling problem in typical practice, verify the idea and methods of the dissertation.
