Research And Design Of Manufacturing Resource Planning

AbstuaetManufacturing Resource Planning (MRP II) is a kind of integrated management information system, which has being widely adopted by all sorts of the world. In this paper , author briefl~ introduced status of MRP Ii in the manufacturing, its history, characteristic ,. present applied conditions of internal manufacturing and the main distinguish froni Enterprise Resource Planning ( ER?).In the basis of adequately comprehending theory and method of MRP II application software , the system structure €hart and the function module logistic flow chat, author presented a kind of MR.? II software development module using the method of object-oriented technique, and implemented the design and planning of Production Activity Control (PAC).The subsystem decision was presentedL which based on the investigation and study to the YanSban University Machine Shop, thinking of the system generality and according with the characteristic of manufacturing industry whose type was job-shop and small-lots. In this paper, it was mainly introduced that database structure design, system structure chart, system principal result, function of every modular and program flow diagrams. Still more, facing the difficult point of PAC?sequencing, author presented a method which used structural event model to solve sequencing problem dynamically and explained? with a sample.Furthermore, the subsystem can program job plan oriented shop automatically according to the norm of work hour and capacity data that provided by technological route and work center. It can also choose which priority rules were used artificially.When the rush job was added, it can modify the job plan quickly and issue dispatching lists.The malpractice which operations manag~s worked by experience using band were corrected. So it was able to improve the utilization rate of resource and work efficiency and bring economic benefit for enterpfiae.
