Study On Web-based Collaborative Commerce Mode And Key Technologies Of Electromechanical Equipment's After-sale Maintenance Service

Electromechanical equipment is the material basis of enterprise production. With the development of equipment to be large-scale, high-speed, electromechanical integration and structure-complication, the technologies of equipment's manufacturing and maintenance have become increasingly complicated, and the demand of equipment maintenance for resources, such as information, technology, manpower, material and finance, has been increasing, which makes it difficult for individual enterprise to have all these resources, and it hard to achieve a high level of equipment maintenance service through the traditional after-sale maintenance mode, such as the modes of equipment maintained by manufacturers, user or a single contractor. Therefore, in this thesis, in accordance with the status of the technology development of computer, network communications, signal detection and fault diagnosis, based on the thought of web-based collaboration, and based on the analysis of remote maintenance and intelligent e-maintenance, a web-based collaborative business mode for electromechanical equipment's after-sale maintenance service was proposed and studied, some decision support models and the collaborative purchasing model of spare parts for electromechanical equipment's after-sale maintenance service were established, and a web-based collaborative commerce platform for electromechanical equipment's after-sale maintenance service was designed. Specific research work is as follows:â‘ Based on analyzing the business mode change of electromechanical equipment's after-sale maintenance service, a web-based collaborative business mode for electromechanical equipment's after-sale maintenance service was proposed, and the modes of business cooperation, information exchange, knowledge growth, value-adding, co-profit, profit distribution of electromechanical equipment's after-sale maintenance service under collaborative business mode were studied.â‘¡Through analyzing of the decision-making elements of the electromechanical equipment's after-sale maintenance service under collaborative business mode, the group decision-making process of maintenance service was established; based on the theory of reliability and maintainability, take it for the optimization goal to maximize the total revenue in equipment service life, maintenance period and maintenance time for the optimization variables, The models of maintenance period and maintenance time for life-type electromechanical equipment's after-sale pre-maintenance with changing maintenance periods were established, and the change of pre-maintenance strategy was analyzed; the evaluation index system and fuzzy comprehensive evaluation model of the spare parts suppliers for electromechanical equipment's after-sale maintenance service were established, and the selection mechanism of spare parts suppliers was analyzed.â‘¢Through analyzing the characteristics and the mode change of spare parts purchasing in electromechanical equipment's after-sale maintenance service, the demand model and purchasing model of electromechanical equipment's spare parts in condition based maintenance service were established, the demand model and purchasing model of life-type electromechanical equipment's spare parts in pre-maintenance service with equivalent period and changing period were established, and using Visual Fortran emulation program to calculate the optimal purchasing strategy of spare parts in equivalent period pre-maintenance service; two kinds of collaborative purchasing modes in electromechanical equipment's after-sale maintenance service were proposed and their models were established.â‘£According to the characteristic of collaborative business mode of electromechanical equipment's after-sale maintenance service, the enabling technologies of this maintenance service were analyzed, including the technologies of network security, network communication, signal detection, fault diagnosis and a collaborative business platform named web-based collaborative business system of electromechanical equipment's after-sale maintenance service, the mode of collaborative business system was analyzed, and the structural framework and functional structure of this system was designed in detail.
