The Designing And Implementing Technology Of Information Management System Of Production Scheduling For Standard Workshop Of Chengdu Airplane Company

With China's accession of the World Trade Organization (WTO), the process of economic globalization steps up and the competition increasingly hastens. The level of informationization has been a crisis of enterprise to react promptly and efficiently to changes in environmental and marketing condition, and to participate in keen market competitions. While the productivity of an enterprise is governed by its management of workshop production scheduling, it is practically important to explore how to integrate advanced information technologies with mcinagement of workshop production scheduling in our manufacturing enterprises, and accordingly develop such an information management system of workshop production scheduling.In the paper, with reference to the hybrid of ERP/MRPII/JIT, and investigation of the existing workflow as well as production scheduling management mode of Standard Workshop of Chengdu Airplane Company, the solution to information management system of production scheduling for Standard Workshop of Chengdu Airplane Company(viz. Workshop IMS) ispresented. The paper delineates the improved production flow, data flow, architecture, system model, data structure, design of network topology and operating environment of Workshop IMS. Furthermore, the main frame of the workshop IMS system is discussed in detail.Workshop IMS is multi-tier distributed application with mixed computer model with B/S and C/S, The paper emphasizes on such techniques in the distributed environment as database modeling, data access, integrated heterogeneous databases and data security, and explains how to architect a multi-tier distributed application on web, as well as cooperation technique.The paper analyzes mobile agent and knowledge discovered in database, and puts forward the model of knowledge discovered in database in the distributed environment applied to quality following sub-system of Workshop IMS.Workshop IMS is successfully used to Chengdu Airplane Company, the main achievements of which are listed as follows: timely management in production locale, aided management of technical information, intelligentized management of production scheduling, online management of warehouse, systematization of market management, management of measure and management of quality follow, and which provides a cooperative environment among functional departments of Standard Workshop, and between Standard Workshop and others, so that Agility of production scheduling for Standard Workshop is raised.
