The car is flexible in making modular the research of MBOM implementation technology

1The generation of MBOM go up from the design, product structure convention differentiates by functional assembly, its written guarantee what composition of a picture shows craft to get on the design as follows the stock detailed account that reach (EBOM) according to production craft asks, undertake recombining to data, get MBOM. 1.

2The to MBOM demand purchase department in MRP plans to the demand stock demand of MBOM (MaterialRequirementPlanning:MRP) the core that computation is manufacturing management system. It is the base that each production such as plan management, inventory management, cost management runs a function, if its fundamental pursues 21.

3The importance of MBOM can see through the fundamental of MRP, MBOM (ManufacturingBOM:MBOM) all in all place is had in MRP computation, main show is in 3 respects: MBOM listed in the product the need in producing a course controls the stock with management in the round, here stock the object configuration that the meaning is the component that in pointing to production process, appears, and this object configuration is opposite the production of the enterprise is significant for management activity, need tries to control and manage; MBOM clarity expresses clear stock explicitly the amount between concerns. Quantitative impact is to have content of MRP calculative key. Stock the quantitative impact in MBOM has sheet to hold data and stand-alone amount. Odd outfit data points to father stock namely and child stock the quantitative scale between both concerns. Stand-alone amount is to point to a certain stock concern with the quantitative scale between end item. Particular concern is had between both, stand-alone amount can be passed recursive and amalgamative, get on foundation of odd outfit amount; MBOM conveyed these stock the production between assembles core order to concern. Such, the MBOM computation of production system replied to need what stock the amount with need, and still answer stock need in what workshop. If want to answer stock in when need production or get ready, must know stock treatment or the absolutely time that purchase. Be based on MBOM of construction of craft core flow to be opposite for automobile manufacturing industry, the core between the stock that the key of MBOM is a product is made assemble. Accordingly, the core that finds these stock from inside craft file is made assemble a relation, can get MBOM. This is based on the core idea of MBOM of construction of core technological process namely. Its key depends on how representing flow of product craft key. 2.

Structure of flow of core of 1 product craft cultivates the technological process of the product to be comprised by node of certain workmanship flow unit, these unit node conveyed constituent unit of production, the production that also conveyed a product at the same time rigs a process. If set out from the viewpoint of technological process, the production of the product can be sent regarding is by a series of the place of technological process node that rises according to correlation of concern of some kind of construction forms. Traditional technological process is in charge of completely change and be being safeguarded by Technical Division, but to truckload assembly for craft, as a result of working procedure manage with the production of the workshop early or late close together and relevant, for the Technical Division that develops as main and responsible product, want to control truckload technological process completely, meeting influence manufactures operational efficiency. Accordingly halfway enterprise controls these whole technological process by workshop technology group, and the Technical Division that develops as the product, the core technological process that controls it only is OK (my company takes this kind of kind namely to the management of technological process) . Administrative levels is compositive relation between the node of photograph adjacent, be the same as the relation between administrative levels node can be serial, also can be collateral. Concern to this kind, the form that we can cultivate with structure of craft core flow will convey. The node of the tree represents technological process node, the filiation between burl dot conveyed the composition between disparate arrangement of ideas to concern namely, conveyed again with the serial relation between administrative levels node. For accurate expression core technological process pursues, introduce fictitious concept. Fictitious an assembly between the component in conveying technology of the core in making a process to flow process, do not put in this stock in production process of products plan and production. Through fictitious come to string of concern of conventional technology stock to fashion whole craft core technological process. Next graphs assemble the give typical examples of the process for miniature car product, 2.

2 be based on craft core flow in node of technological process of tectonic MBOM product is corresponding production a certain or certain stock. Because the essence of technological process node is,this is one or a group of process, this process should output stock necessarily. And output stock to make this, regular meeting has a certain number of input stock, these input stock the output stock that or is node of a technological process, or is initiative condition stock. Because this says a node of a technological process is inevitable and corresponding stock. Since correspondence of technological process node is worn stock, can use corresponding stock so go " replaces structure of " technological process to cultivate medium flow node, realize the technical data according to correspondence of place of technological process node, basically point to procedure commonly. The stock that the information in procedure indicated to place of this technological process wants treatment or manufacturer, and it is exclusive that its code, can serve as the node of MBOM. If be treatment procedure, show the raw material that understands a need or wool are bad; If be to assemble procedure, listed to assemble this stock needs other and total stock and relevant measure. Yuan Fucai makings, wool is bad and child assembly parts regards this as stock child node appears in MBOM. The origin attribute that decides foster son node through relation of node of father and son and use branch. Such, according to technological process, combine the craft information of technological process node, can construct the MBOM that gives a product, following plan institute show its core algorithm: Should see, the construction of MBOM is an integrated process, on the base that needs to considering product structure design, technology design, production to manage in the round, with the design of the product BOM, craft BOM is a foundation, combine the relevant data such as technological process, procedure, inventory, finance affairs, ability gets having the MBOM of real value. It is the example that our company realize MBOM below. 3. MBOM is applied mediumly in enterprise of 5 water chestnut 3.

1 modular structural thought is modular the structure is to be in development control is flexible on the basis that changes manufacturing technology to create thought and stock concern, of the administrative method to workmanship data and product generate undertake summing up, combine proper products plan, research is flexible the relation between the stock that the product place with manufacturing specific and whole set uses, assure to press flexible the stock that production plans to ask generation is accurate, this is to use computer technology the structural design the product, technology design and flexible the typical example that manufacturing design marriage rises. Face flexible the product line that turns production, build with application with modular the system of modern technology quota that stock technology concern is core, can improve the engineering capability of product quality not only, more important is to be able to optimize manufacturing management, those who assure stock information is accurate communicate and synchronism is newer, shorten production cycle. In much product craft, the craft scope of application with each respective component that installed chart to amount to it, if " engine installs " to sheet discharges the 462 engine installation that van uses, the 462 engine installation that double platoon van uses is waited a moment, here we call it " engine to install 1"" engine to install 2" . To electric assembly, also put in same craft condition range, with this analogize- - apply to these same the craft condition limits of kind of limits names for module, simplify the management of ground floor of craft structure tree, implementation builds MBOM quickly. 3. 2 modular the construction of MBOM is right for a series of products, the distinction between the product is halfway craft only the relation is different the result of generation. The difference of stock is changed namely the halfway technology concern is different outcome between the product, concern according to craft, distribute stock piece, the craft suitable scope that craft norm presses these stock place correspondence namely together build those who rise, the stock that converts these difference through managing a database undertakes modular managing mix by technology concern build, can form the complete MBOM that decides exclusively. Production information system passes pair of MBOM core technology to have consideration, the stock that can receive manufacturing need the amount with need, stock origin and whereaboutldirection. To realize " to reach the designated position immediately systematic " ① lays next solid foundations. Modular union forms tree of product workmanship structure, simplify the government that craft structure establishs, according to module with truckload relation, use consult the relation of the tree is OK tree of new production product structure, those who implement seed profit stock and seed profit technology is perfect and unified. If pursue,5 are shown. 3. Technician of put in storage of organization of data of MBOM of 3 much products is arranged by the requirement form branch of craft core flow, assure the accuracy of information. Because produce craft to had been formed, engineering technology member it is very clear that the craft of responsible to place component makes relation and scope of application (the own job that this is them) , when the configuration that respecting cultivates, be accepted very easily by technical personnel place, make a kind of tool that helps them arrange file of much product craft. Person specially assigned for a task coachs and manage, make sure data information is successful put in storage. Because these craft information are to distributing,be in the craft file of different page, what different technician forms process and development direction understanding to the product is different, different to the description of craft limits, because this needs the profundity of full-time to understand series product to form process and the technician that develop way,help limits of craft of directive and accurate description, appliance has certain meaning to reach but the encode method of enlarge sex takes order to module. Because have guidance of person specially assigned for a task and government, the method is proper, we finish the MBOM of 90 products that the company produces at that time inside a month, the MBOM that can make other product quickly on these foundations (our company share 300 products) , accuracy rate is amounted to 95% , through the test and verify of a month, accuracy rate is amounted to 98% . Solve the norm that will perplex an enterprise for years to forbid to be mixed truly the issue that defends hard. Place laying a plan is shown for much product modular the impact that MBOM makes graph last word join WTO to give automobile industry to bring as China, how to achieve administration of informatization of automobile manufacturing industry, reduce a lot of no use, all sorts of engineering segment that are not appreciation, enhance effectiveness, reduce cost, shorten manufacturing cycle becomes the issue that manages a first consideration. Make engineering technician as, the development that whole journey enters this enterprise to make information system and apply, program job is built in what MBOM is in charge of below PDM. Comprehend among them after a lot of secret, feel informatization is not terrible. If can make full use of,the personnel of this enterprise regards a system as the brunt of development, compare with the software photograph that buys professional company, cost can reduce 10 times above. The business that the key is him flows and data shedding wants reasonable, clear. The organizer of data is data structure architect, establish and defend the work of responsible database, assure the correct put in storage of information and output, logarithm occupies deliver use program clarity, and these are to buy software to also cannot be bought.
