Design And Implementation Of Process Resources Management System Based On Three-dimensional Modle

Process resources are the basic data of manufacturing information technology and are the important information to support CAPP system. In order to face the needs of personalized and diversified users, remodeling process resources to adapt to the rapidly changeable and unpredictable market competition and achieving the integration, sharing and optimal using of technology resources are key links to raise the rapid reaction ability of enterprises.This thesis presented the characteristics of technology resources, research design and implementation of process resource management system. It focused on the process of resource modeling, process resource coding system design, process descriptions and integrated resource sharing technology. Aiming at processing capacity, time, cost and other targets, research on the process of resource decisions is taken, optimized allocation model of process resource were established and heuristic process resource allocation algorithm was designed. Finally, based on the resource modeling and integration technology, the development of the process resource management system were showed, which achieved the functions of process resource management, application of information technology resources and resource integration.The thesis made a detailed study from the following aspects:1.Make the definition and classification of resources. Aiming at the application of process resource, process resource management system was designed and the key issues of the system were presented.2.Further study on process resource modeling, integration of resources and processes described were made. The study analyzed the structure, capabilities and status of the technology resources and the modeling process. The process resource model and relationship model were established by adopting the Object-Oriented method. According to the process resource categories and attributes, classification and coding were made and then classification process resource coding structure was put forward. In the means of XML-based databases and resources description, the present study proposed the mechanism and key technologies based on the view and intermediate files. It researched on the two ways:mapping mode and the manners of updating the data, which achieved the integration of heterogeneous resources.3.On the basis of the relationship of technology resource model, the research studied process resource capacity, built the capacity models of equipments and proposed the technical resources selection method based on the assembly ability. The optimized resource allocation model was established aiming at the cost and delivery time. This study used node graph to describe the entire process route of the products and designed the heuristic algorithm for optimal allocation of resources in the means of nonlinear process.4.This system showed serval functions such as the process resource model management, process resource object management, process resource application and system integration, which was employed in enterprises as well.
