[Abstract]:The further economic integration of the competition between enterprises is changing from the previous point of competition for customers, suppliers, manufacturers, R & D center, between dealers and service providers and other partners in the supply chain network competition. Today, complete with a strong supply chain means have strong competitiveness. An important part of building materials and equipment as the manufacturing industry of equipment manufacturing industry, its development level is an important manifestation of a country's overall industrial level, but also give priority to the development of our country, and rise to the strategic level of the industry. At the top of the value chain of building materials and equipment manufacturing industry with high added value, strong leading role, has a close relationship with multiple industries. The background of our country, the importance of building materials and equipment manufacturing industry is more obvious. In the whole supply chain will directly affect the competitiveness of the core status of building materials and equipment manufacturing enterprises to the whole. Supply chain competitiveness. With the idea of supply chain of manufacturing enterprises on a single mode of operation, has great significance for improving the competitiveness of the whole supply chain. The internal supply chain emphasizes the coordination between various departments within the enterprise, can be regarded as the external supply chain reduced. Between the core enterprise departments, between the core the enterprise and the supplier, between the core enterprise and the outsourcing vendor frequent information flow, capital flow and logistics enterprises directly influence the operation of the supply chain. The building materials and equipment manufacturing enterprises as the background, the research in the perspective of the supply chain under the mode of operation of the enterprise and the supply chain optimization problem, the main research contents and work are as follows: (1) analysis of the importance of the thought of the supply chain to improve the building materials and equipment manufacturing enterprises, the production process of building materials and equipment manufacturing enterprises of the general Cheng Shuli, Each department of the enterprise supply chain as part of the elements above. (2) is established by using Petri net model of supply chain building materials and equipment manufacturing enterprises, and verify the correctness of the model. The introduction of the time constraints, establishes the stochastic Petri net (SPN) and its isomorphic Marco Markov chain, analyzed by response time the rate and model the performance of model change and restructure the matrix based algorithm for subnetting and Optimization Based on the model. (3) through the performance analysis of the model, pointed out the direction of process optimization and model modification. To evaluate the performance of the new model from the time point of view, combined with agile the idea of supply chain, the production plan to change the situation of join in the basis of the new model, to improve the dynamic performance of the model. (4) on the basis of theoretical research, the development of the building materials equipment manufacturing enterprises based on stochastic Petri net The information platform of supply chain management has been designed, and the main modules have been designed. The resource sharing inside the enterprise supply chain has been realized. The information management platform has been applied in an enterprise in Tangshan, and achieved the desired results.
