From the aspects of basic management, resource integration and database design, we put forward the design concept of the informationization of the supply chain system of medical products in China. The information system can ensure the precision and rationality of the supply of medical products, and provide high-quality services and service efficiency, and meet the different needs of different customers.展开更多

Open global market offer more choice to customer, and it become changea ble and unpredictable as consumers’ needs become more and more characteristic an d diversified. Various new technology coming forth and application accelerate th e rapid change of the market. The manufacturing enterprises were compelled t o change their strategy by the variability of the market, and time has been put to the all-important place. There is a need driven by the market to set up a ne twork design and manufacturing mode which have rapid market responsiveness. In order to meet the need for network manufacturing, the organization and manage ment of manufacturing enterprise need a completely innovation, next generation o f manufacturing system must have the character such as digitization, flexibility , agility, customization and globalization and so on. As for an enterprise in au to industry, how to gather together the orders through the distribution, and rap id produce the product which can meet the customer’s need, it is the key that th e contemporary enterprises succeed in the competitive market. The competitive market requires rapid product development. Close cooperation amo ng the designers will accelerate the product development by shortening the devel opment cycle, improving the product quality and reducing the investment. It has been emphasized in the methodology of concurrent engineering (CE). But sometimes those partners are distributed in the world, so there is a need for an importan t technology contribution to collaborative engineering, and supporting distribut ed designers for rapid product development. This paper focuses on a collaborative design system: Product Digit Collaborative Design System (PDCDS). The solution of PDCDS can make it more efficient and rel iable to visit teledata as well as we can get it from local database. It will be ease to get the newest design process information aided by PDCDS, and it will h ave higher efficiency by collaborative work. Comparing with other traditional Pr oduct Data Management (PDM) software system, PDCDS have some new characters such as group, dynamicness, synchronization or asynchronism working mode, and the hi story recorder is needed, and it also surport Webservice.展开更多

It consists of integrated product model, the expert system of product manufacturability evaluation and the controller of concurrent design. With the help of the controller of concurrent design, each feature of a part can be designed and evaluated based on manufacturing knowledge and resources, and can be modified according to the results of evaluation. The machining method of design feature can be selected based on manufacturing knowledge. So real time concurrent product and process design can be implemented based on integrated product model that is established based on generalized feature. Products and its design process can be optimized with the help of this system. The information and function integration of product design process can be realized. The time to market and the cost of products can be reduced.展开更多

From this point of view, both CAD/CAM software and hardware are considered as tools. A great advantage of this view point is that a very flexible paradigm is introduced, in which the CAD/CAM system for a particular industrial application can be customized and built by selecting a set of tools. This paper intends to shed some lights on the principles for designing the architecture of such a tool integration environment. Although such an environment is no more than a computer program sys. tem itself, its particular characteristics arising from its unique role, i.e., tool integration, make the discussion on the designing of an environment architecture nontrivial. The paper externalizes the author's experiences in implementing an tool integration environment for production machines.In particular, the discussion renders some insights into the concepts such as tool integration models, various views of an environment architecture, classification of data into tool-data and environment data, and employment of the information relativity principle in making an environment architecture flexible. The paper will take production machines design as a target application that an environment system is developed for, owing to its extreme complexity and thus make sense of coverage of other engineering applications.展开更多
