Production system simulation optimization
From razor barbed wire the production of some of the simulation system, optimize production unit of automation research about "digital", made from some of the razor wire concept and practice of "tool" gradually developed step by step, into every aspect of manufacturing engineering, computer aided manufacturing engineering (CAPE) barbed wire concept. In 1996, manufacturing process and digital began to construct complete manufacturing process in manufacturing, developing framework established on the server razor process model, products and production data sharing, each "tool" type of professional seamless integration module together, to support the process each barbed link, include: production plan, line balance, the definition and &fair standards, machining and CNC programming, assembly process, quality control, man-machine efficacy, wire workshop layout, work instruction, process file etc, formed a complete functions, operating in the computer "digital factory (DigitalFactory)". Here, the simulation razor technology as the main widely. High-performance computer and network support of virtual manufacturing environment is "digital factory" operation. The key link wire of manufacturing process and the essential characteristics of the actual processes precede physics is displayed, production process and possible problems can barbed also be found in the planning of the early, so early. In early 2000, Israel Tecnomatix company in the companys wire annual meeting, the concept of MPM delivers crisp, support manufacturing process, namely life cycle from process planning, manufacturing technology and equipment razor barbed wire to product process, the whole manufacturing chain of all members including OEM designers, engineers, equipment manufacturing process and material suppliers to razor wire a virtual enterprise. To form the best manufacturer MPM delivers crisp production strategy to support business strategy, its implementation results further barbed wire promoting the digital manufacturing solutions to the comprehensive development. In the past two years, many manufacturers PLM increasingly unity of architecture razor of digital platform, MPM delivers crisp PLM has become an inseparable part of platform. Digital manufacturing and product research, unified environment barbed in sharing technology simulation advantage into full play, and meanwhile comprehensive promotion in manufacturing data management, process management and resource management wire skills.This equipment is haiyan national standard product quality supervision and inspection center with zhejiang university and zhejiang new Oriental fasteners Co., razor LTD. With its successful development, and put into use marks to use the fastener to over 40 years of traditional pickling wire process, experts say this epoch-making significance. In the use of steel fastener production enterprises need to pass before peeling derusting, barbed drawing, the traditional method is to use hydrochloric acid, sulfuric acid pickling, etc. But this process first on the environment pollution. wire Relevant materials show, haiyan consumes steel nearly 100 tons per ton steel acidification sewage produced by 0.2 tons fastener production enterprises, razor barbed wire the calculation of 500,000 tons annually produces wastewater, enterprises and social environment under a lot of pressure. Secondly, because of razor wire the acid pickling, degree of concentration control difficult to master, the more standard "hydrogen brittleness" hidden trouble. Zhejiang university biological systems barbed wire engineering and food science professor wang jie says: "in high-strength fasteners failure analysis of the causes of hydrogen brittleness problem with" razor the most typical failure causes of product, more than 50% of."In data acquisition phase, according to data warehouse service demand analysis barbed and theme domain analysis, from ningbo highway administration (local automotive test and maintenance and management of the enterprises accessories sales governmental wire departments, hereinafter referred to as the male in all the subordinate enterprises) data submitted data cleaning up after conversion, and manned razor in data warehouse. In the multi-dimensional data structure of creating and managing stage, based in management of establishing data analysis wire model will be in the data warehouse data according to certain levels of polymerization and collect information analysis, constitute the multidimensional barbed view, what choose finally certain storage, storage in the multidimensional view OLAP server. The aim is to build data warehouse wire management decision analysis, satisfies demand, so the user friendly interface, the software use also is very important. In addition, consider customer razor barbed wire for the development and use of cost, so in OLAP application system considering using current mature BI products as data warehouse razor wire in front, to reduce the cost of development tools.
