Study On Mechanized Agricultural Production System Based On Integrated Manufacturing System Mode

Building a scientific and reasonable mechanized agricultural production system is the core of agricultural modernization and sustainable development. In the paper, mechanized agricultural production systems at home and abroad were analyzed, the mechanized agricultural production system and the manufacturing system were compared, and therefore a mode of integrated agricultural production system (IAPS) by a combination of the integrated manufacturing system mode and a mechanized agricultural production system was put forward and into it a systematic research was carried out.IAPS is an integrated system composed of human resource, physical resource, including facilities and equipment for agricultural production, materials, energy and kinds of assistive equipments, and soft resource, such as agricultural technology and production information involved with agricultural producing process. The system is characterized by applying a combination of information technology, biology technology, management technology and production technology to the whole life circle of products produced in agricultural enterprises, taking means of information integration, resource integration, function integration and process integration, realizing an integration and optimum operation of material flow, information flow and value flow of agricultural production, and making an agricultural enterprise supply its products with high quality and low cost to the market early , provide its customers with good service and ensure producing process resource-saving and environment-friendly so that the competitive power of the enterprises will be promoted.One kind of architectures of IAPS was constructed in the paper. The architecture includes five views, that is, function view, organization view, information view, resource view and process view, six subsystems, i.e., management information subsystem, production technology subsystem, producing process subsystem, quality assurance subsystem, subsystem of resource and materials and environment evaluation subsystem, two supporting subsystems, namely computer network and database/knowledge base and one information connection with outside.An algorithm for optimizing match of farm crops, working procedure and machinery in IAPS was proposed in the paper. The algorithm properly integrates some methods in operation research, computer simulation and expert system for designing integrated agricultural producing systems with supports of a database.A decision supporting system for pumping station renovation was developed for supporting decision to renovate pumping stations when various techniques for resource integration, function integration and process integration are applied to these pumping systems, or mechanized irrigation systems.A preliminary application of the techniques and methods mentioned above to a farm in Chongqing was performed. A general plan for building an IAPS in the farm was made, an important subsystem of the system was implemented and a good achievement was obtained.The paper is a part of the national 863 project"Research on architecture and green features of contemporary integrated manufacturing system"(project number: 836-511-880-007).
