【摘要】：敏捷制造被認(rèn)為是制造模式發(fā)展的主要趨勢(shì)之一，虛擬企業(yè)作為敏捷制造的具體組織形式，以其快速響應(yīng)市場(chǎng)，滿足客戶需求的特性被越來(lái)越多的研究和應(yīng)用。而傳統(tǒng)的虛擬企業(yè)多以企業(yè)單元作為基本的研究對(duì)象，難以在市場(chǎng)需求發(fā)生變化時(shí)做出快速有效的反應(yīng)，缺乏必要的柔性和靈活性。而單元化制造快速響應(yīng)市場(chǎng)需求，靈活組織生產(chǎn)計(jì)劃的特點(diǎn)與虛擬企業(yè)的組建理念不謀而合，本文將單元化的制造方式引入到虛擬企業(yè)的構(gòu)建和生產(chǎn)運(yùn)作上，在虛擬企業(yè)中推行單元化的制造方式，既有效的提高了虛擬企業(yè)的敏捷性，也拓展了傳統(tǒng)單元化生產(chǎn)的應(yīng)用空間，具有一定的積極意義和研究?jī)r(jià)值。 根據(jù)虛擬企業(yè)資源分布和加工任務(wù)的特點(diǎn)，構(gòu)建虛擬企業(yè)單元化的概念模型。按照一定的原則和虛擬企業(yè)加工任務(wù)的工藝流程，對(duì)任務(wù)加以分解，形成與中間任務(wù)對(duì)應(yīng)的邏輯制造單元LMU，各LMU的組合形成邏輯加工路線LMP。每一個(gè)LMU對(duì)應(yīng)多個(gè)可以完成加工任務(wù)的敏捷制造單元AMU，AMU與LMU為多映射關(guān)系，即一個(gè)邏輯制造單元LMU可由多個(gè)敏捷制造單元AMU完成，同樣的，每一AMU可能具備多個(gè)LMU所描述的加工能力。對(duì)不同制造單元的選擇和有序排列，形成可執(zhí)行的加工路線EMP,通過(guò)對(duì)諸如質(zhì)量、時(shí)間和成本等優(yōu)化目標(biāo)考量，尋求最優(yōu)的EMP。與虛擬企業(yè)一樣，虛擬企業(yè)單元化制造系統(tǒng)隨著加工任務(wù)的出現(xiàn)而形成，隨著任務(wù)的完成而消失。本文主要從資源的選擇以及動(dòng)態(tài)制造單元的重構(gòu)兩個(gè)方面對(duì)虛擬企業(yè)單元化制造系統(tǒng)進(jìn)行分析和研究。在基于制造單元的虛擬企業(yè)資源選擇過(guò)程中，著重考慮時(shí)間、成本和質(zhì)量等指標(biāo)對(duì)資源選擇的影響，并據(jù)此構(gòu)建了資源的優(yōu)化選擇模型，以期構(gòu)建最優(yōu)的敏捷加工路線。動(dòng)態(tài)制造單元作為虛擬企業(yè)單元化制造系統(tǒng)的基本單位和執(zhí)行層，其敏捷性和柔性對(duì)整個(gè)系統(tǒng)至關(guān)重要，需要根據(jù)任務(wù)的變化進(jìn)行不斷地重構(gòu)。動(dòng)態(tài)制造單元的重構(gòu)在本質(zhì)上是對(duì)資源的選擇和聚類(lèi)，通過(guò)對(duì)資源的選擇確定待加工工件在不同加工路徑上的加工數(shù)量，然后利用成組技術(shù)中常用的金氏聚類(lèi)算法對(duì)設(shè)備工件矩陣進(jìn)行成組聚類(lèi)，，完成對(duì)動(dòng)態(tài)制造單元的重構(gòu)。 最后，結(jié)合某模具企業(yè)的實(shí)際情況，通過(guò)對(duì)企業(yè)存在的問(wèn)題加以分析，完成了對(duì)企業(yè)的加工流程和制造單元的重構(gòu)，并結(jié)合綜合評(píng)價(jià)模型對(duì)重構(gòu)前后的效果加以評(píng)價(jià)，說(shuō)明重構(gòu)的有效性和必要性。
[Abstract]:Agile manufacturing is considered to be one of the main trends of manufacturing pattern development. As a specific organization of agile manufacturing, virtual enterprise has been studied and applied more and more for its rapid response to the market and to meet the needs of customers. But the traditional virtual enterprise takes the enterprise unit as the basic research object, so it is difficult to respond quickly and effectively when the market demand changes, and lacks the necessary flexibility and flexibility. The characteristics of flexible organization of production planning coincide with the concept of virtual enterprise. This paper introduces the method of unit manufacturing to the construction and production operation of virtual enterprise. The implementation of the unit manufacturing method in the virtual enterprise not only improves the agility of the virtual enterprise effectively, but also expands the application space of the traditional unit production. It has certain positive significance and research value. According to the distribution of virtual enterprise resources and the characteristics of processing tasks, the concept model of virtual enterprise unit is constructed. According to certain principles and the technological process of virtual enterprise processing task, the task is decomposed, and the logical manufacturing unit LMUU corresponding to the intermediate task is formed, and the combination of each LMU forms the logical processing route LMP. Each LMU corresponds to multiple Agile Manufacturing Units (AMUUMUs) that can accomplish processing tasks, and LMU has a multi-mapping relationship with LMU, that is, a logical manufacturing unit (LMU) can be accomplished by multiple Agile Manufacturing Units (AMPs) AMUs. Each AMU may have the processing capabilities described by multiple LMUs. The EMPs of different manufacturing units are selected and ordered to form an executable processing route, and the optimal EMPs are sought through the consideration of optimization objectives such as quality, time and cost. Like the virtual enterprise, the unit manufacturing system of the virtual enterprise is formed with the appearance of the processing task and disappears with the completion of the task. In this paper, we analyze and study the unit manufacturing system of virtual enterprise from two aspects: the choice of resources and the reconfiguration of dynamic manufacturing cells. In the process of resource selection of virtual enterprise based on manufacturing cell, the influence of time, cost and quality on resource selection is considered, and the optimal selection model of resources is constructed in order to construct the optimal agile machining route. As the basic unit and executive layer of the virtual enterprise unit manufacturing system, the agility and flexibility of the dynamic manufacturing cell is very important to the whole system, so it needs to be reconfigurable continuously according to the change of the task. The reconfiguration of dynamic manufacturing cells is essentially the selection and clustering of resources. The number of workpieces to be processed in different processing paths is determined by the selection of resources. Then, the Kim's clustering algorithm is used to cluster the workpiece matrix of the equipment, and the dynamic manufacturing unit is reconstructed. Finally, according to the actual situation of a mould enterprise, through the analysis of the problems existing in the enterprise, the reconfiguration of the processing process and manufacturing unit of the enterprise is completed, and the effect before and after the reconfiguration is evaluated by the comprehensive evaluation model. The effectiveness and necessity of reconstruction are illustrated.
