Study On The Job Shop Work Management Aadministration System In Small And Medium-Sized Enterprises

Compared with the developed countries,there is the situation of China's small and medium-sized enterprises with significant labour-intensive,low-tech,low value-added products and technology to the neglect of the development of processing characteristics,and the result is uncompetitive in the fierce market conditions.The core competitiveness of modern enterprises has changed into enterprise management from scale and funds of enterprises.The adaptive management software must be used to improve the level of management in the information time.So it is very important that advanced management concept is used in enterprises in this condition.MRP system is not very efficient in production planning and control of job shop, especially for the one that contains three-level structure:shop,subshop and workgroup.After reviewing the traditional methods of production planning,this paper firstly brought forward the concept of simple shop and complicated shop and analyzed the different production-organizing methods of them,then it discussed the advantages and disadvantages of MRP system,the possibility and the limitation of its application to the complicated shop,the main idea of Optimized Production Technology(OPT), and put forward the model of a MRP-OPT based job shop production planning and control system,in which MRP system is responsible for shop planning and control while OPT-based system for the planning and control of sub-shop.Based on this model,this paper discussed an example of a job shop production planning and control system used in JI'ER shop of DLRW by introducing the design thought,system structure,work flow and function of some software modules.Finally,this paper did some research on the software techniques involved in the system development and relized shop work system and subshop work system on the system architecture,method of system development and develop tool with PowerBuilder.
