【摘要】：隨著經(jīng)濟的高速發(fā)展，企業(yè)所在的市場環(huán)境是越來越復(fù)雜。國際全球化的競爭、多樣化和個性化的客戶需求對制造業(yè)企業(yè)的產(chǎn)品提出更高的要求。因此，制造企業(yè)的市場主導(dǎo)已經(jīng)從賣方市場轉(zhuǎn)向買方市場，大規(guī)模定制的生產(chǎn)模式應(yīng)運而生。大規(guī)模定制的生產(chǎn)模式在一定程度上提高了制造企業(yè)對市場的應(yīng)對能力，滿足了顧客及時化、多樣化和個性化的產(chǎn)品需求。然而，大規(guī)模定制生產(chǎn)模式下企業(yè)面臨著產(chǎn)品種類繁多、生產(chǎn)任務(wù)加大、企業(yè)的生產(chǎn)過程動態(tài)多變、生產(chǎn)工藝千變?nèi)f化、生產(chǎn)對象重復(fù)率會變低等特點，這些特點對企業(yè)進行零件工藝設(shè)計工作帶來了巨大的挑戰(zhàn)。然后傳統(tǒng)的工藝設(shè)計方案都是從零開始，對企業(yè)積淀的工藝知識和工藝制定經(jīng)驗重用率低，嚴重影響企業(yè)生產(chǎn)管理水平的提高，因此，為了確保企業(yè)的有效運營，產(chǎn)生更大的經(jīng)濟效益，迫切需要以高效率和低成本的方式獲取準確的零件工藝設(shè)計方案。 本文根據(jù)大規(guī)模生產(chǎn)模式下生產(chǎn)系統(tǒng)的特點，結(jié)合特點提出大規(guī)模定制環(huán)境下零件工藝重用的總體要求；然后對于大規(guī)模定制下零件工藝重用方法進行總體規(guī)劃。首先，依托產(chǎn)品零件的設(shè)計和制造理論，，結(jié)合零件的結(jié)構(gòu)和功能相同相似的思想，定義零件重用對象——制造單元結(jié)構(gòu)，并以制造單元結(jié)構(gòu)為載體建立基于相似零件結(jié)構(gòu)變型設(shè)計的重用結(jié)構(gòu)模型；其次，通過分析現(xiàn)有零件實例表達的方法，分析已有方法的特點，并提出基于本體的零件工藝實例表示模型，構(gòu)建了包含概念、屬性、關(guān)系、關(guān)系之間屬性和公理規(guī)則五元素的零件工藝領(lǐng)域本體和零件工藝本體知識庫，并建立基于本體的零件工藝實例表示方法；再次，分析確定零件實例檢索的原則和檢索要素前提下，為了保證檢索的有效性和準確性，提出了基于工藝相似的零件實例檢索方法，分別從零件類型、形狀特征、精度特征以及材料特征四個方面來綜合考察零件的相似性。通過結(jié)合德爾菲法和層次分析法來研究零件實例檢索四個要素特征權(quán)重的設(shè)定；然后，根據(jù)零件工藝實例修改的要求，提出零件實例修改的方法和流程；最后，通過案例闡述了零件重用方法的具體操作過程。
[Abstract]:With the rapid development of economy, the market environment of enterprises is more and more complex. The international globalization competition, the diversification and the individuation customer demand put forward the higher request to the manufacturing enterprise's product. Therefore, the market dominance of manufacturing enterprises has changed from seller's market to buyer's market, and mass customization production mode has emerged. The production mode of mass customization improves the ability of manufacturing enterprises to deal with the market to a certain extent, and meets the needs of customers in time, diversification and individuation. However, under the mass customization production mode, enterprises are faced with the characteristics of a wide variety of products, increasing production tasks, dynamic and changeable production processes, changing production processes, and low repetition rates of production objects, etc. These characteristics have brought great challenges to the part process design of enterprises. Then, the traditional process planning schemes are all from scratch, which has low reuse rate of process knowledge and process development experience accumulated by enterprises, which seriously affects the improvement of production management level of enterprises. Therefore, in order to ensure the effective operation of enterprises, It is urgent to obtain accurate parts process design scheme with high efficiency and low cost. According to the characteristics of production system in mass production mode, this paper puts forward the overall requirements of part process reuse in mass customization environment, and then makes a general plan for part process reuse method under mass customization. First of all, based on the design and manufacturing theory of product parts, combined with the idea of the same structure and similar functions of the parts, we define the component reuse object-manufacturing unit structure. The reused structure model based on the structural variant design of similar parts is established with the manufacturing cell structure as the carrier. Secondly, the characteristics of the existing methods are analyzed by analyzing the methods of expressing the existing parts. A part process case representation model based on ontology is proposed, and the knowledge base of part process domain ontology and parts process ontology is constructed, which includes five elements of concepts, attributes, relationships, attributes and axiom rules. The method of part process case representation based on ontology is established. Thirdly, the principles and elements of part case retrieval are analyzed to ensure the efficiency and accuracy of the retrieval. A part case retrieval method based on process similarity is proposed to investigate the similarity of parts from four aspects: part type, shape feature, precision feature and material feature. Through combining Delphi method and analytic hierarchy process to study the setting of feature weight of the four elements in part case retrieval. Then, according to the requirements of part process case modification, the method and process of part case modification are proposed. The concrete operation process of the method of part reuse is explained through an example.
