Concurrent Design Method For Effective Management Decision Study

With the development and application of the technology of computer, information network and modern manufacture, manufacturing industry is getting rid of thetraditional product pattern and sets up a new design thought and management mode-Concurrent Engineering. With the development of Concurrent Engineering, some supporting tools have been researched and developed such as DFM, DFA, DFT and DFC. Although the application of these tools has shortened the developed period of production greatly, it can't provide the effective support on management decision so far. This paper explains the research on the theory and method of mechanical product concurrent design facing effective management decision. The study work divides into three parts:First, this dissertation explains the study of the effective management oriented decision theory, including product management request and thought of effective management decision of modern enterprise; proposes a implemental method of MDSS-CE; does the research on the working mode, the content of decision, the evaluation system and the decision method of MDSS-CE; builds a framework model of effective management decision.Second, doing the method research work. This essay explores the product concurrent design implement method facing effective management decision; studies the construction of integrated concurrent design circumstance and the architecture of the integrated framework; analyzes functional model of PDM implement. This paper probes into the key technology of distributional product concurrent design integrated environment including message and process integration based on PDM framework; poses a management organization pattern based on CE; provides an integrated circumstance and implemental method for mechanical product concurrent design facing effective management decision.Third, developing a prototypic system. This paper explains the method of the development of a concurrent design system facing effective management decision, including: Construction of a distributional system structure based on client/server; Developing a integrated interactive application for concurrent design based on Delphi; Setting up a database management system using SQL Server 2000.Last, DHMDCS has been developed on the basis of disc spring develop process of Yangzhou Spring Ltd. This dissertation introduces the architecture, function and its implement of the prototypic system.
