The network makes what complex part faces below the environment make catenary consider in coordination

The 1 definition that produces chain in coordination is defined 1 produce chain in coordination (Collaborative Manufacturing Chain, CMC) . Producing chain in coordination is around core business, process of will complex part makes process mediumly partly, the production service that provides by place of the many companies in the network respectively is finished, each press the service chain that sets a whole orderly certainly between production service. In this service chain, every - node is a production service, between node concern to be decided by requirement of the structural characteristic of the spare parts, technology, production cost, quality and date of delivery orderly early or late [10] . CIMS the 12nd the 1st period auspicious sharp edge wait: Make catenary what complex part faces below network production environment consider to make catenary can use next type to describe in coordination in coordination: CMC= ∑ Ni=1Si, i=1, 2, 3, ... , n; Si=(NSi, oi, sij) , j=1, 2, 3, ... , n. In type, si is whole the I in producing chain in coordination production service, NSi is the name of production service Si, oi makes process to make what service Si place finishs, sij described production service between Si and Sj of next production service concern orderly early or late. 2.

The 2 characteristics that produce chain in coordination produce chain in coordination is a kind of collaboration production mode below network environment substantially, its characteristic is: (1) network. Internet of benefit in order to is the information freeway of the mark, will distributing to become an organic whole in the production resource join of different situation, realize information communication and resource to share, the spare parts is made through competing cooperative means undertakes. (2) is fictitious change. Producing chain in coordination is the form of production activity organization that is based on network space, each segments that the spare parts produces are finished by different company, the form that uses dummy company will organize management. (3) technology optimization. To make some kind of complex part, enterprise of the leader of an alliance can seek the partner with technology, best equipment in network space, each enterprises can produce its technology advantage adequately, form best combination, in order to achieve technical optimization. (4) opens a gender. The biggest characteristic of computer internet network is open sex, build what go up in this foundation to produce chain in coordination, also will be an open system. (By nature of 5) distributinging collect. Make catenary be comprised by many companionate enterprises in coordination, these companies are distributed to span even in different district on the space national boundaries, the dispersive defect on region of this cultivate land can be below support of computer network technology through information compositive be able to make up for. (6) dynamic sex. Make the member that makes chain in coordination unlike traditional business invariable in that way, combine together temporarily through opportunity of a certain market for common interest however. 3 produce chain in coordination make the as unified as evolution process application language that build a model (Unified Modeling Language, UML) order picture will describe what produce chain in coordination to build a course. UML order picture expresses the mutual concern of the object to be graph of a 2 dimension, fore-and-aft it is time axis, transverse axis represented each independent targets in cooperation. The object expresses with lifeline, when the object exists, the part expresses with a dotted line; When the process of the object is in activation condition, lifeline is a double line line. The mutual activity between the relevant object that UML order picture suits to use a description to make catenary generate the place in the process to involve in coordination very much. Graph 1 it is what produce chain in coordination to build a course, the solid line that arrowhead takes in the graph described enterprise of the leader of an alliance, leaguer enterprise and the mutual activity that production service registers the object such as the center, arrowhead on-line text offerred a hereon interactive simple description. Produce chain in coordination generate basically include the following measure: (1) program of process of analysis of craft of spare parts treatment is the bridge that join products plan and product make, its are main the task is to be machined the spare parts chooses reasonable treatment method and treatment order, so that can press a design,demand production gives eligible finished product part. The technology program procedure that the form that makes chain in coordination establishs a process to be able to regard network environment approximately to play complex part, it relies on the craft information of the spare parts likewise. In making the compose of catenary establish a procedure in coordination, enterprise of the leader of an alliance should undertake to the spare parts craft is analysed above all, understand the each technology requirement of the spare parts, find out main technique requirement and treatment key, preliminary differentiate the composition of process, choose the treatment method of spare parts surface, arrangement machines order and assorted working procedure, the treatment of certain part is periodic. In the spare parts treatment craft analyses level, enterprise of the leader of an alliance should ask according to the production of the spare parts (include time of amount, precision, quality, delivery to wait) the production resource that evaluates this company, see its whether contented requirement, decide missing process capability. Assessment result will regard production service as the basis of discovery. After undertaking to the spare parts craft is analysed, the spare parts technology that enterprise of the leader of an alliance will acquire to face a network to be made in coordination plans (Collaborative-Oriented Process Plan, COPP) . Define the 2 spare parts craft that face a network to be made in coordination to plan (COPP) . COPP is the gather of the process of all likelihoods that complete treatment of a spare parts, it includes to complete all process of this spare parts, and the labor situation that place of every working procedure includes, the gets manufacturing type, part orderly early or late structure characteristic between working procedure, technology asks to wait for a tie. Nextpage and traditional process are different, the working procedure in COPP and labor situation all not related to facilities of job shops, workshop section, treatment and tool couplet, and the treatment of certain working procedure in COPP decides not completely also orderly. The design of COPP is based on working procedure to center a principle, the treatment of the spare parts is finished inside a few a few working procedure centrally, the content of every working procedure and labor situation are more, press between labor situation first thick hind essence of life, first advocate hind second, first the regulation such as the aperture after the face has sort. Graph the 2 COPP that are spare parts of key of some aviation engine, among them node O expresses working procedure, node P represents labour step, join arc expresses node between concern orderly early or late, AND node is used at describing the working procedure gather that concerns orderly early or late without strict treatment. By the graph knowable, the treatment process of this spare parts includes 9 process. Underline above all, line cut combines an aspect, before can undertaking next, hind groovy treatment, before perhaps undertaking, treatment of back end face, perhaps undertake the face is machined combinative, do not have between these working procedure strict concern orderly early or late. Belong to Bao Bi as a result of this spare parts, be out of shape considering treatment wait for an element, finish in afore-mentioned working procedure only rear the treatment that can have appearance side, undertake fluorescence examines finally. Graph 2 in working procedure of treatment union scale included 5 labor situation again, ordinal it is thick mill mill of aperture of craft of scale of the aperture of craft of scale of scale of combinative scale, union of half essence mill, the union that get boring, union that turn over Huo, essence combines an aspect. (2) the craft ability that production service discovers to place does not have this company in machining production process in the light of the spare parts, company of the leader of an alliance goes making a service register central search to be able to satisfy the production service of process technology requirement, to production service the package outside these working procedure the provider has machining. Outside be opposite each assist working procedure, production service center may return the production service of many contented requirements. Outside if make a service register a center to cannot be returned,be being satisfied assist the production that working procedure asks serves, whether do the rationality that the integrality that enterprise of the leader of an alliance answers part drawing appearance, technology asks and material choose appropriate etc offer relevant modification opinion. After enterprise of the leader of an alliance is finishing production service to discover, the spare parts technology that will acquire to rely on production service plans (Manufacturing Service-Dependent Process Plan, SDPP) . Define the 3 spare parts craft that rely on production service to plan (SDPP) . SDPP is one includes the digraph of AND node and the OR node that take working procedure sign, the corresponding working procedure in the production service that SDPP returns through registering production service the center and COPP undertakes have a youthful look is become binding deciding, each in SDPP production service has the capacity of corresponding working procedure in the COPP that finish. Graph the 3 SDPP that are spare parts of key of some aviation engine, underline among them, fluorescence examines these 2 working procedure are finished by proper motion of the leader of an alliance, the others working procedure criterion outside the bag is finished to corresponding production service. The OR node that takes working procedure sign introduced in the graph, it is contented between 2 OR node all and optional production service that treatment of this working procedure asks assembles, if machine combinative scale,this working procedure can be finished by production service F or production service I. (3) make catenary generate the work of raw ingredient humanness that makes chain in coordination to choose in coordination with optimize configuration 2 phase. In choose level artificially, enterprise of the leader of an alliance describes the service provider in the file to contact information and provider of each production service to undertake contacting through making a service above all, the final quoted price that enquire and affirms each provider, production cycle, and the respect information such as treatment quality. Next, the result that enterprise of the leader of an alliance returns to making service provider each undertakes evaluating, the production with apparently improper eliminate serves (or because quoted price is exorbitant, or because treatment is periodic too long) , obtain a SDPP after choosing. Graph the 4 SDPP after be being chosen for, among them in the working procedure of scale of online cut union, service B exceeds enterprise of the leader of an alliance to anticipate as a result of quote and by eliminate; In the working procedure that machines around end panel, because machine cycle,serve G criterion too long and by eliminate; In machining the process that combines an aspect, because machine cycle,serving F also is too long and by eliminate. In optimize configuration phase, the SDPP after enterprise of the leader of an alliance will be chosen undertakes production a process according to the tie condition such as cost, cycle optimize configuration, generate finally produce chain in coordination, graph 5 produce chain of the spare parts in coordination for key of some aviation engine. To the much talk process that can complete by same production service, undertake to its add up is handled, graph 5 in before treatment, hind groove these two working procedure can be finished by production service C, before treatment, back end face these two working procedure can be finished by production service F, undertook add up to its respectively, incorporate its for a node. (4) the contract signs enterprise of the leader of an alliance to choose to produce chain bestly in coordination, with relevant production service provider autograph is made an appointment with, produce chain in coordination make one's bow runs level. Making catenary run level in coordination, will make item of a cooperation, use the synergic project that is based on a network to manage a form to undertake administrative to the production process of whole spare parts. The process that Nextpage4 is based on ant to make catenary algorithmicly optimize configuration to make catenary optimize configuration in coordination in coordination is affirmatory outside assist the production that working procedure chooses finally serves, and between production service early or late sequential process, it is a combination optimizes a problem character actually. To this kind of problem, still do not have polynomial solution to be able to seek an accurate solution up to now, use heuristic algorithm to solve commonly. The article uses ant algorithm, configure a problem with solving what produce chain in coordination to optimize. Produce chain in coordination in the network in optimizing configuration process, undertake optimizing to choosing the SDPP after to use ant algorithm, generate produce chain in coordination. Particular procedure is as follows: Be based on ambiguous administrative levels to analyse a law to undertake be evaluatinged integratedly to making a service above all, for make choice of of each working procedure a best production serves; The node that installs list Tabuk(s) to be used at depositing ant to choose next (namely the production of correspondence of every working procedure serves node) , and the initiative node every ant (namely SDPP the 1st node) in park Tabuk(0) , be in every two node (I, the setting is same information element between J) (τ Ij(t)=c) with information element increment (Δ τ Ij=0) , computational T hour comes according to the size of information element later K ant is in the probability that chooses next node J in node I, pkij(t)= [τ Ij(t) ] α * [η Ij] Allowk of ∈ of β ∑ K [τ Ij(t) ] α * [η Ij] β , j ∈ Allowk; 0, j? Allowk. Among them, α , β controls information element and heuristic information to weigh 2 parameter that want rate relatively respectively, give before computation; η Ij=1/dij, dij is I, the carriage cost between J node; Allowk expresses K the node that ant can choose next. Will choose next node J according to the size of probability, insert node J list Tabuk(s) . When Tabuk list is full, computation K the cost Lk of node of ant place choice, calculate information element increment, Δ τ Kij=QLk, (I, by the side of J) ∈ Tabuk describes; 0, Δ τ Ij:=Kij of τ of Δ of Δ τ Ij+ . Later according to Ij(t)+ of τ of * of equality τ Ij(t+n)= ρ Δ τ Ij is Ij(t+n) of τ of chroma of element of information of the computation between every 2 node (the abiding degree that ρ is information element, give before computation) , install increment of element of information of the computation between every 2 node to be Δ τ Ij afresh: =0. List of clear empty Tabu, make ant new circulate, the circulation is regular frequency, when the node that chooses when all ant is identical, generate to produce chain what optimize in coordination namely. 5 make catenary compose what be based on a network to create platform in coordination build in coordination thinking with the nuclear idea that moves to produce chain in coordination is to be based on the framework model that faces a service (Services-Oriented Architecture, SOA) [11-12] , use the combination of production service, the production resource that distributings to be nodded at different ground union rises to complete the production process of complex part jointly. In specific implementation process, compose built a network to create platform in coordination, the form that makes chain in order to support in coordination is built with move. The network creates platform in coordination is one moves below semantic Web frame, it is the information infrastructure of main function with offerring production resource to share a service, this platform is based on application to serve a provider (Application Service Provider, ASP) mode provides project management, make catenary compose build in coordination wait for applied service. The user is registered after become platform user and loginning, the form that can have cooperating with production chain builds the job. Ground of different of the casing before combining engine of some model aviation is made in coordination, elaborate systematic implementation. Above all, found spare parts COPP, graph the COPP of the 6 casing before be engine of some model aviation, basically comprise by working procedure node, AND node, show with the form of the tree in interfacial left frame, right frame shows the descriptive information of node of corresponding working procedure; The interface is described in working procedure information, the user can be based on network to make noumenon machine a requirement to undertake semantics changes a description to working procedure. Next, below the support that matchs algorithm in semantics, in user general COPP outside assist the production service that working procedure and platform make a service register a center undertakes matching, generate the SDPP of this spare parts. Graph the SDPP of the 7 casing before be engine of some model aviation, finally, the user is based on SDPP to finish what produce chain in coordination to optimize generate. This process includes two measure: The evaluation information such as the quote that ① user inputs production service through SDPP management interface, time limit for a project, use ambiguous administrative levels to analyse a law to complete the integrated evaluation of production service, the production that decides every working procedure chooses finally serves (if pursue 8) , graph 8 in the production that the production that takes asterisk serves to be final choice namely serves; ② is based on ant algorithm to finish what produce chain in coordination to optimize generate, the user chooses a SDPP, click production catenary to optimize pushbutton can. The graph produces chain of the casing before the engine of after be being optimized to pass ant algorithm namely, makes some model aviation that frame of 8 interfaces right shows in coordination. After making catenary compose build a success in coordination, the synergic project that participates in an enterprise to be able to use platform place to offer each manages a tool, undertake data of the plan monitoring of spare parts production task, documentation is shared, complete the whole moving process that produces chain in coordination. The article put forward 6 last words to face the concept that creates catenary of complex part in coordination, analysed the characteristic that produces chain in coordination, discussed what produce chain in coordination to generate in detail with evolution process and be based on what produce chain of ant algorithm in coordination to optimize configuration. Be based on a network to make catenary what production platform builds can use Internet in coordination in coordination, produce what be in different area dispersedly equipment resource, intellective resource and all sorts of core ability, quickly group synthesis opens, compositive, the network that cooperate with is allied, the demand that answers the market in time changes, gain competitive advantage, for the network the collaboration of advanced production company below production environment and resource are shared offerred a kind of new pattern.
