頁集成制造單元面向多產(chǎn)品類型的形成和多樣化批量生產(chǎn)技術(shù)摘要：追求的類型和不同多產(chǎn)品體積(MPTVV)生產(chǎn)快速反應(yīng)、快速的切換，使結(jié)構(gòu)線的轉(zhuǎn)移制造系統(tǒng)不再是一成不變的。細(xì)胞形成(CF)算法的關(guān)鍵技術(shù)是細(xì)胞制造系統(tǒng)(CMS)。目前，CF手段主要擴(kuò)展理念的成組技術(shù)(GT)，涵蓋了許多資源能力匹配分析及其算法。不同的約束都認(rèn)為，但很少利用綜合運(yùn)用。摘要針對(duì)生產(chǎn)單元的問題(MC)下形成MPTVV生產(chǎn)模式，形成典型的MC技術(shù)集成分組類型的細(xì)胞(GC)、流量類型(FC),即繼承了細(xì)胞(IC)技術(shù)分析提出了基于自由度。面向?qū)嶋H生產(chǎn)像交貨期約束、生產(chǎn)批號(hào)、設(shè)備能力、關(guān)鍵設(shè)備、關(guān)鍵部分和機(jī)共享等，是一個(gè)完整的地層模型的建立和內(nèi)部相互關(guān)系綜合分析這些約束。進(jìn)而，形成目標(biāo)的類型及其生成程序變換器在聯(lián)合作用形成的約束和規(guī)則是傳播。在案例研究，形成三個(gè)高度平衡氣相色譜第一；然后俱樂部實(shí)施形成基于相同的數(shù)據(jù)表明良好的平衡作用荷載和flow-style細(xì)胞生產(chǎn)關(guān)鍵任務(wù)；當(dāng)任務(wù)是調(diào)整，通過使用IC形成方法在FC配置的結(jié)果上構(gòu)建了一項(xiàng)新計(jì)劃，更優(yōu)的性能flow-style生產(chǎn)的表現(xiàn)。該制度的研究比較不同類型的細(xì)胞強(qiáng)烈說明驗(yàn)證的綜合MC形成快速制造資源的支持下MPTVV轉(zhuǎn)變生產(chǎn)方式。關(guān)鍵詞：多產(chǎn)品批量生產(chǎn)類型和變異，細(xì)胞的形成，流式制造單元，繼承制造單元1介紹 如今，多種類型和可變的生產(chǎn)模式已成為必然選擇，對(duì)于大多數(shù)企業(yè)來說，在適應(yīng)或正在適應(yīng)不斷變化的需求，我們的社會(huì)當(dāng)然這是一個(gè)自然的結(jié)果。幾個(gè)類型和流動(dòng)的專用生產(chǎn)線和多種類型和離散柔性生產(chǎn)線，多類型和變量生產(chǎn)的小型或中型生產(chǎn)批量生產(chǎn)之間的定位模式，定位系統(tǒng)的變異性和快速反應(yīng)的效率和靈活性兩者的優(yōu)點(diǎn)。細(xì)胞制造業(yè)是一個(gè)可容納這種類型的生產(chǎn)模式，并支持快速響應(yīng)制造系統(tǒng)的生產(chǎn)組織形式，細(xì)胞制造的核心是制造資源的重組和重用;自治，協(xié)作為特征的制造單元和靈活性的核心組成部分，因此，細(xì)胞的形成和重構(gòu)技術(shù)是執(zhí)行CMS的鑰匙。目前，細(xì)胞的形成（CF）技術(shù)主要集中在它的構(gòu)造算法?？赡苄纬傻囊?guī)則和約束方面。如多路線和設(shè)備類型，工作時(shí)間分配，批量生產(chǎn)，設(shè)備共享，單位平衡和機(jī)容量已全部參與，但有沒有這些因素的綜合應(yīng)用。研究人員像安田等人1和GARBIE等人2用于細(xì)胞分析的相似性系數(shù)。TB根據(jù)不斷變化的市場解決集群和細(xì)胞形成的問題，皮萊等3，提出了一個(gè)健全的設(shè)計(jì)方法，結(jié)果細(xì)胞結(jié)構(gòu)竟然是相對(duì)穩(wěn)定的。智能算法被引入到CF求解之中，智能算法考慮的因素，如部分?jǐn)?shù)量、路線加工時(shí)間、設(shè)備容量設(shè)備的狀態(tài)和細(xì)胞的平衡和細(xì)胞間移動(dòng)的最小化的目標(biāo)。ASOKAN等4，普拉巴卡蘭等5，和其他許多學(xué)者采用蟻群算法。VENKATARAMANAIAH等6，構(gòu)建了一個(gè)單元的配置與使用特殊元素的混合啟發(fā)式算法。MAHAPATRA等 7，細(xì)胞負(fù)載平衡和細(xì)胞間移動(dòng)和就業(yè)，解決遺傳算法的最小化集中。曼蘇里等8，使用GA算法來研究瓶頸設(shè)備、特殊零部件和設(shè)備共享的約束。韓元等9，采用了模糊ART神經(jīng)網(wǎng)絡(luò)算法來解決復(fù)雜的零部件和設(shè)備的分組問題。DEFERSHA等10，引入CF遺傳算法的并行運(yùn)算，在許多實(shí)際限制，如單元的配置，替代工藝，設(shè)備共享，容量和負(fù)載考慮平衡或和生產(chǎn)費(fèi)用。FTS等11，切割CF卡的過程分為兩個(gè)步驟。首先，構(gòu)建了多目標(biāo)函數(shù)為尺度單位，然后采用一個(gè)單一的目標(biāo)函數(shù)來優(yōu)化內(nèi)部和單位之間的移動(dòng)。白氏等12，他們的注意力主要在FC形成的理論和緊急動(dòng)員一批批量生產(chǎn)的技術(shù)上。作為一個(gè)整體，上述研究主要集中在靜態(tài)細(xì)胞形成，而在可持續(xù)發(fā)展的動(dòng)態(tài)形成的研究很少，甚至不說綜合形成多類型的細(xì)胞。本文的主要是制造單元（MC）的多產(chǎn)品類型的多樣化和變異量（MPTVV）生產(chǎn)模式下的問題，從多類型的MC，綜合形成模型和基于方法的綜合建設(shè)。統(tǒng)一的約束，制定規(guī)則和算法將會(huì)是研究和決策的工具。 2 技術(shù)上的挑戰(zhàn) 根據(jù)MPTVV生產(chǎn)模式，產(chǎn)品類型及數(shù)量是在不斷變化，在不同時(shí)期的時(shí)間或階段，不同時(shí)期市場需求的變化所引起的，因此使制造系統(tǒng)的配置變化的直接原因是動(dòng)態(tài)的要求。在細(xì)胞制造系統(tǒng)（CMS），這種變化將最終歸咎于細(xì)胞形成，或由細(xì)胞進(jìn)行和實(shí)現(xiàn)。 細(xì)胞的形成和重構(gòu)的實(shí)質(zhì)是優(yōu)化制造資源的分配，它是一種能力制造資源的分配或再分配。資源分配的需要之間的極端情況下的權(quán)衡“一臺(tái)機(jī)器是一個(gè)細(xì)胞”和“整條生產(chǎn)線也是一個(gè)細(xì)胞” 。此外，以實(shí)現(xiàn)快速的資源轉(zhuǎn)化，而不是任務(wù)與資源的相匹配，條件下的資源分配和優(yōu)化比如一批關(guān)鍵設(shè)備、關(guān)鍵零部件、設(shè)備共享，也是必須要考慮的。執(zhí)行不成功的重要原因是傳統(tǒng)的CF技術(shù)的應(yīng)用，缺乏綜合考慮。 CF的結(jié)果是邏輯細(xì)胞，所以有細(xì)胞間和細(xì)胞中的機(jī)器有沒有固定的歸屬、沒有明確的界限。機(jī)器可以作為一個(gè)獨(dú)立的“設(shè)備單位” ，對(duì)于分散的任務(wù)，或者他們可以分享它們的能力與其他細(xì)胞，并完成任務(wù)與其他機(jī)器一起。在這種情況下，它可能會(huì)出現(xiàn)離散單元。結(jié)果配置是一個(gè)多元結(jié)構(gòu)的“完整”的單位和一個(gè)獨(dú)立的單位組成。傳統(tǒng)的分析，強(qiáng)調(diào)太多，可能會(huì)導(dǎo)致部分家庭和細(xì)胞的獨(dú)立性不和諧的生產(chǎn)。因此，瓶頸業(yè)務(wù)和設(shè)備，將出現(xiàn)和交配組裝生產(chǎn)的要求不能得到滿足。此外，細(xì)胞負(fù)荷分布不均，機(jī)器不能被細(xì)胞間的共享。 MPTVV生產(chǎn)模式下的細(xì)胞類型應(yīng)靈活多樣。在生產(chǎn)多種產(chǎn)品的類型和體積小或試生產(chǎn)中，細(xì)胞（GC）組類型的細(xì)胞形態(tài)是必需的，而在大規(guī)模批量生產(chǎn)中，需要實(shí)現(xiàn)連續(xù)生產(chǎn)。此外，在不同時(shí)期，繼承可持續(xù)重構(gòu)將是一個(gè)基本要求，努力推進(jìn)傳統(tǒng)組技術(shù)（GT）為基礎(chǔ)的技術(shù)的直接原因是，由于需求的快速變化頻繁布局調(diào)整是難以實(shí)現(xiàn)的。作為一個(gè)剛性的形成技術(shù)，有太多的努力是物理布局調(diào)整的成本。設(shè)備及零件的相似性為基礎(chǔ)的施工方法上存在的資源要求，只強(qiáng)調(diào)適應(yīng)，而不是生產(chǎn)流程的流暢性，認(rèn)為這也是一個(gè)重要的任務(wù)路線組織者同意的問題。流線式運(yùn)行在MC的形成也是一個(gè)重要的目標(biāo)。打擊周期性變化的需求，以減少成本和機(jī)器調(diào)整的影響，CF程序具有繼承原有的生產(chǎn)線。存在的CF分析氣相色譜儀，研究主要集中在類型的細(xì)胞（FC）和繼承細(xì)胞（IC）的相對(duì)很少，相同的地位，形成約束分析和不同類型的管委會(huì)統(tǒng)一建設(shè)提出。 選區(qū)、功能界別和IC分別代表不同的目標(biāo)和CF的目標(biāo)，并在制造系統(tǒng)中是典型的細(xì)胞形態(tài)。面向他們將是進(jìn)行整合形成多類型細(xì)胞的技術(shù)分析。3 MC的形成和其約束分析的綜合模型 MC形成多個(gè)相關(guān)的約束下，在MC的形成，如生產(chǎn)的要求，交貨時(shí)間和作為批處理內(nèi)部外部因素，處理時(shí)間，機(jī)器的能力，關(guān)鍵設(shè)備和可選擇的機(jī)器一并考慮。此外，在生產(chǎn)周期時(shí)間目標(biāo)，成本，設(shè)備必須滿足實(shí)用，因而MC的形成過程又是一個(gè)多目標(biāo)優(yōu)化過程，沒有最佳，但許多次優(yōu)的解決方案，其中普遍存在。在這里，約束和目標(biāo)分解和它們的相互關(guān)系，以不同類型的MC如圖1所示。圖1 MC形成和約束分析的綜合模型 在CF中資源、路線和任務(wù)是三個(gè)主要的需要數(shù)據(jù)，還繼承了CF使用前進(jìn)行比較的數(shù)據(jù)源配置模式。CF卡規(guī)則，包括路由選擇，機(jī)器（類型）選擇和機(jī)器任務(wù)分配規(guī)則。這里主要的CF約束是機(jī)器能力，關(guān)鍵還是質(zhì)量和關(guān)鍵設(shè)備。輸出政策的細(xì)胞和設(shè)備，在機(jī)器的能力，在資源分配中，三個(gè)加班的情況下，外包和設(shè)備采購，可以選擇短缺的情況下潘氏規(guī)則分區(qū)組成。在不同類型，甚至MC的形成階段的過程中，必須采取量化指標(biāo)，包括相似系數(shù)，操作數(shù)的細(xì)胞間，細(xì)胞負(fù)載和生產(chǎn)節(jié)拍平衡，所有這些規(guī)則，約束和目標(biāo)，構(gòu)建形成多類型的限制細(xì)胞，其中大部分是蹣跚，但一些特殊用途，例如，為FC的形成，是有規(guī)則，強(qiáng)調(diào)操作平衡的路線和設(shè)備的生產(chǎn)節(jié)拍時(shí)間，和目標(biāo)細(xì)胞中的節(jié)拍，壓力平衡。 形成三種類型的細(xì)胞，是不是獨(dú)立的，還是相互關(guān)聯(lián)的，主要的階段：設(shè)備集群的資源選擇與分配，細(xì)胞的優(yōu)化和調(diào)整，電池的輸出都可以被重用集群和輸出的過程是完全通用的，而不同的分配和優(yōu)化。規(guī)則、約束和目標(biāo)需求可以選擇不同類型的細(xì)胞。 根據(jù)圖1，選區(qū)和功能界別有兩個(gè)基本的細(xì)胞（BC），而且FC是GC和IC的擴(kuò)展也可以看作是基本細(xì)胞BC的一個(gè)擴(kuò)展，作為一個(gè)整體，GC和FC構(gòu)造一樣，就像BC和IC一樣。4一體化形成的目的和步驟 為方便起見，采取流動(dòng)的符號(hào)表達(dá)圖約束。

Karl，YI KyongsuReal-time slipbasedIntegrated Manufacturing Cell Formation Technology orienting Multi-productType and Variant Volume ProductionAbstract：What is pursued by multi-product type and variant volume(MPTVV) production is rapid response and quick switching，so that structure of transferring line in manufacturing system is no longer unalterableCell formation(CF) algorithm is the key technology of cellular manufacturing system(CMS)Currently，CF methods are mainly extended on the idea of group technology(GT) that covers a lot on analysis of resource capability matching and its algorithmVarious constraints are considered，but seldom utilized comprehensivelyAimed to the problem of manufacturing cell(MC) formation under MPTVV production mode，integrated formation Technologies for typical MC as group type of cell(GC)，flow type of cell(FC) and inherited cell(IC) are presented based on technical analysis of CFOriented to practical production constraints like delivery time，product batch，equipment ability ,key machine，key part and machine sharing，etc，an imegrated formation model is constructed and intemal imterrelations of these constraints are analyzed syntheticallyUlteriorly，formation goals of types of MCs and their formation procedures under joint effect of formation constraints and rules are spreadIn casestudy，three highly balanced GC are formed first; then FC formation are implemented based on the same data which indicate good balancing effect of cell load and flow-style production for key tasks；When task is adjusted，a new scheme is constructed on the result of FC configuration by using IC formation method，and more optimal performance of flow-style production is manifestedThe proposed comparative study of different type of cells strongly explains the validation of integrated MC formation in support of rapid manufacturing resource transformation under MPTVV production modeKeywords：multi-product type and variant volume production，cell formation，flow style manufacturing cell， inheriting manufacturing cell1 Introduction Nowadays, multiple type and variable production mode has been an inevitable choice for most enterprises, which is a natural result in the course of adapting or being adapted to the ever changing needs of our society. As a mode positioned between few type and mass production of flowing dedicated production line and multiple type and small or medium production of discrete flexible production line, multiple type and variable production has both advantages of efficiency and flexibility targeting variability and rapid response of system. Cellular manufacturing is a form of production organization which can accommodate to such type of production mode，and well support rapid response of manufacturing systemThe core of cellular manufacturing is the reorganization and reuse of manufacturing resources；manufacturing cell characterized with self-government，collaboration and flexibility is the core componentTherefore，technologies of cell formation and reconfiguration are also the keys in implementation of CMS Presently,technologies of cell formation(CF)are mainly focusing on its construction algorithmLikely aspects of formation rules and constraintssuch as multi-routes and equipment types，work time assignment，batch production， equipment sharing, balancing of unit and machine capacity have all been involved，but there is an absence of integrated application of these factorsResearchers like YASUDA，et al1 and GARBIE，et al2 used similarity coefficient for cell analysisTb solve the problem of formation of clusters and cells under changing market，PILLAI，et al3，proposed a robust design method based on demand forecast and the result cell structure turned out to be relatively stableIntelligent algorithm was introduced for CF solvingConsidering factors like part number, route，processing time，equipment capacity equipment status and objectives of cell balancing and minimization of inter-cell movingASOKAN，et al4，PRABHAKARAN，et al5,and many other scholars adopted ant colony algorithm VENKATARAMANAIAH, et al6, constructed an unit configuration with exceptional elements using hybrid heuristic algorithmMAHAPATRA，et a7，concentrated on cell load balancing and minimization of inter-cell moving and employed GA for solutionMANSOURI, et al8， studied constraints of bottleneck equipments，exceptional parts and equipment sharing using GA methodWON，et al9，adopted fuzzy ART N-N algorithm to solve grouping problem of complicated parts and equipmentsDEFERSHA，et al10，introduced GA parallel arithmetic into CF, in which many practical restriction like cell configuration，substitute process，equipments sharing and capacity and load balancing or them，and production fees were taken into accountFTS，et al11，cut CF procedure into two steps Firstly， multi-objective function was constructed for scaling units，and then a single objective function was employed targeting optimization of moving within and between unitsBAI，et al12，paid their attention to FC formation theory and technique for emergency mobilization batch volume productionAs a whole，above researches are mainly focused on static cell formation，while studies on sustainable dynamic formation are seldom， even not to say integrated formation of multicell types Main focus of this article will be on the problem of manufacturing cell(MC) diversification under multi-product type and variant volume(MPTVV) production mode From the view of integrated construction of multi-type MCs，integrated formation model and method based on unified constraints，rules and algorithms will be studied，and decision-making tools will be developed2 Technical Challenge Under MPTVV production mode，product type and volume is on constant change at different period of time or stages of different period stemming from market requirement changeSo the direct reason bringing configuration change of manufacturing system is dynamic requirement. In cellular manufacturing system(CMS)，such change will finally impute to cells formed，or be undertakenand realized by cells The essential of cell formation and reconfiguration is optimizing assignment of manufacturing resourceIt is a kind of allocation or reallocation of ability of manufacturing resource Resource assignment needs to tradeoff between extreme cases of “one machine is one cell” and “the whole line is also one cell”Moreovertorealize rapid resource transformation，other than matching between task and resource， resource assignment and optimization under conditions like delivery time，batch，keymachine， key part and equipment sharing have to be considered also Important reason of unsuccessful implementation applying traditional CF technologies is in1ack of comprehensive consideration The outcome of CF is logical cells，so there are no clear boundaries among cells and machines in cells have no fixed attributionMachines may act as a standalone “device unit” for scattered tasks，or they can share their capacity with other cells and accomplish tasks with other machinesIn this case，its possible that discrete units will emergeThe result configuration is a plural structure composed by complete” units and a discrete unitTraditional analysis emphasizes independence of part family and cells too much that may result in unharmonious production Thus， bottleneck operations and equipments will appear and requirement of mating production for assembly cannot be satisfiedMoreover, cell load distribution is uneven and machines cannot be shared among cells Cell types under MPTVV production mode should be flexible and various In multi-product type and small volume or trial production，cell form of group type ofcell(GC)is required，while in mass volume production， continuous production has to be realized Furthermore，during different period，inheriting sustainable reconfiguration will be a basic demandThe direct reason of hard advancing of traditional group technology(GT) based technologies is that frequent layout adjustment due to rapid change of requirement is difficult to realizeAs a rigidformation technology，too many efforts have to be cost on physical layout adjustmentConstruction method based on similarity of equipments and parts only emphasizes adaptation of existed resources to requirements，but not fluency of production flow in the view of routes of tasks which is also an important problem consented by organizersFlow line type running is also an important objective in MC formationAgainst periodical changing requirements， to lessen cost and influence of machine adjusting，CF procedure has to inherit original production lineExisted CF analysis mainly focuses on GC，researches on type of cell(FC)and inherited cell(IC)are comparatively seldom，and same status presents in formation constraint analysis and unified construction of different types of MCs GC，F(xiàn)C and IC represent different objectives and targets of CF and are typical cell forms in manufacturing systemTechnical analysis on integrate formation for multi-type cell will be carried out orienting them3 Integrated Model of MC Formation and Its Constraints Analysis MC is formed under multiple related constraintsDuring MC formation，external factors like production requirement，delivery time and internal ones as batch，processing time，machine ability, key equipment and selectable machine have to be considered togetherAlso，production goals in cycle time，cost，equipment utility have to be satisfied，thus the course of MC formation is again one multi-objective optimization procedure，in which no optimum but many suboptimum solution exists commonlyHere，constraints and goals are decomposed and their interrelations todifferent type of MCs are illustrated in Fig1 Resource.route and task are three main data needed in CF, yet inherited CF has to use former configuration schemas as source data for comparingCF rules include route selection。machine(type)selection and machine task assignment rulesMain CF constraints here are machine ability batch，key or mass pans and key equipmentOutput policies are composed of partition rules for cell and equipment and pan family In case of shortage of machine ability in resource assignment，three scenarios of overtime，outsource and equipment procurement can be selectedIn the process of different types or even stages of MC formation， quantitative indexes including similarity coefficient，inter-cell operation number, cell load and takt time balancing have to be adopted All these rules，constraints and goals construct formation constraints of multi-type cellMost of them are shamble，but some are for special purposeFor example，for FC formation，therere rules that emphasize operation balancing of route and production takt time of equipment，and goals that stress taktbalancing in cell Formation of three type of cell is not independent but interrelated， main stages： equipment cluster resource selection and assignment，cell optimization and adjustingand cell output can all be reusedCluster and output process are entirely universal， while assignment and optimization is different for different type of cell that rules，constraints and goals can be selected in demand According to Fig1，GC and FC are two basic cell(BC)，and that FC is extended on GC and IC can be seemed as extension of BCAs a wholeGC constructs the constraints of FC like that BC to IC4 Objective and Procedure of Integrated Formation For convenience，the flowing symbols are taken to express constraints
