【摘要】：產(chǎn)品低碳設(shè)計(Product Low-Carbon Design, PLCD)是在產(chǎn)品功能實現(xiàn)、性能滿足和經(jīng)濟指標(biāo)符合下,以降低全生命周期各階段的碳排放量為主要目標(biāo)的一種新的設(shè)計方法,與綠色設(shè)計、生態(tài)設(shè)計既有關(guān)聯(lián)又存在明顯的差異。PLCD與原有功能結(jié)構(gòu)、制造工藝、裝拆維修、使用維護(hù)、成本效益等多因素之間的沖突問題是制約其有效實施的主要瓶頸之一,屬于可持續(xù)設(shè)計與制造領(lǐng)域的重要科學(xué)問題之一。PLCD產(chǎn)生的相容性或?qū)α⒌葲_突問題涉及了大量有待更新和處理的新知識,因此,研究PLCD知識演化的多因素、多學(xué)科沖突協(xié)調(diào)方法是一項富有挑戰(zhàn)性和前沿性的研究課題。針對PLCD產(chǎn)生的不相容與對立問題,運用可拓設(shè)計理論研究PLCD沖突協(xié)調(diào)方法：提出了以產(chǎn)品全生命周期碳足跡、成本和性能等的多因素關(guān)聯(lián)建模、建立多維關(guān)聯(lián)函數(shù)的相似檢索與推理機制、分析基于設(shè)計要素變換的動態(tài)分類機理、解決面向多種方法集成的低碳設(shè)計沖突協(xié)調(diào)問題,其主要工作包括：1.針對低碳需求驅(qū)動的PLCD多因素沖突問題,提出了面向PLCD的多因素關(guān)聯(lián)建模技術(shù)。分析并確定產(chǎn)品全生命周期碳足跡、成本和性能等多因素之間的內(nèi)在強弱關(guān)聯(lián)、相容或?qū)α_突等耦合關(guān)系,結(jié)合公理化設(shè)計理論實現(xiàn)低碳需求與產(chǎn)品實例結(jié)構(gòu)的量化映射,通過改進(jìn)成本分析法,建立低碳設(shè)計各階段的成本和碳足跡集成的數(shù)學(xué)模型,通過改進(jìn)性能網(wǎng)狀圖,建立性能內(nèi)在關(guān)聯(lián)及其與前兩者的外在傳導(dǎo)、轉(zhuǎn)化邏輯關(guān)系,應(yīng)用基元理論,構(gòu)建基于低碳結(jié)構(gòu)基的關(guān)聯(lián)知識模型。2.研究低碳設(shè)計實例多維檢索的有效降維問題,提出實例檢索的多維關(guān)聯(lián)函數(shù)構(gòu)建及應(yīng)用方法。針對單維低碳需求檢索的點到區(qū)間距值計算結(jié)果與實際設(shè)計情況不一致問題,通過變斜率原理改進(jìn)側(cè)距,應(yīng)用類推方法,建立多維側(cè)距,針對多維側(cè)距公式計算的相對復(fù)雜性和無降維性,構(gòu)建多維關(guān)聯(lián)函數(shù)模型及其快速降維的算法步驟,給出了基于多維關(guān)聯(lián)函數(shù)的三個層次低碳實例檢索方法。3.針對低碳設(shè)計特征的多層次性、可變換性和分類動態(tài)性問題,提出了基于層次變換的低碳實例動態(tài)分類方法。該方法創(chuàng)新性的運用形式化建模推理方式,將低碳設(shè)計需求與實例特征的相似檢索結(jié)果轉(zhuǎn)換為矛盾問題描述模型,結(jié)合相似基元截集與BP神經(jīng)網(wǎng)絡(luò),給出低碳實例分類原理及其分類傳導(dǎo)變換響應(yīng),依據(jù)低碳設(shè)計需求動態(tài)變化性,建立多維關(guān)聯(lián)函數(shù)變換的低碳設(shè)計多層次、多階級的分類推理方法。4.針對低碳設(shè)計實例不完全匹配的沖突問題,提出了集成TRIZ與可拓的低碳設(shè)計沖突協(xié)調(diào)方法,建立沖突核問題與非核問題的轉(zhuǎn)換流程,結(jié)合TRIZ理論和可拓方法,分別生成基于物理矛盾的不相容問題策略生成、基于技術(shù)矛盾的對立問題策略生成方法,構(gòu)建低碳設(shè)計沖突協(xié)調(diào)過程模型,給出協(xié)調(diào)關(guān)鍵步驟和重要參數(shù)的計算方法,實現(xiàn)沖突協(xié)調(diào)的設(shè)計方案涌現(xiàn)。最后,將以上理論方法應(yīng)用于大型螺桿空氣壓縮機的PLCD原型系統(tǒng),驗證了多因素建模技術(shù)的低碳數(shù)據(jù)庫構(gòu)建、低碳設(shè)計沖突問題的產(chǎn)生機理分析與確定、低碳實例分類技術(shù)、變低碳需求下的核問題與非核問題轉(zhuǎn)換、沖突協(xié)調(diào)方案涌現(xiàn)技術(shù)、方案評價尋優(yōu)等的理論技術(shù)與方法的可行性和有效性。
[Abstract]:The product Low-Carbon Design (PLCD) is a new design method to reduce the carbon emission at all stages of the life cycle. The conflict between the PLCD and the original functional structure, the manufacturing process, the assembly and disassembly maintenance, the use maintenance, the cost benefit and the like is one of the main bottlenecks that restrict the effective implementation of the PLCD, and belongs to one of the important scientific problems in the field of sustainable design and manufacture. The problems of the compatibility or the opposite of the PLCD involve a lot of new knowledge to be updated and processed. Therefore, the multi-factor and multi-subject conflict coordination method for studying the evolution of the knowledge of the PLCD is a challenging and front-edge research project. In view of the incompatibility and the opposite problem of the PLCD, the extension design theory is used to study the PLCD conflict coordination method: a multi-factor association modeling based on the full life cycle carbon footprint, cost and performance of the product is proposed, and the similar retrieval and reasoning mechanism of the multi-dimensional correlation function is established. The mechanism of dynamic classification based on the transformation of design factors is analyzed, and the coordination problem of low-carbon design conflict is solved. The main work includes:1. In order to solve the problem of multi-factor conflict of PLCD driven by low-carbon demand, a multi-factor correlation modeling technology for PLCD is proposed. The quantitative mapping of the low-carbon requirement and the product instance structure is realized by combining the public-chemical design theory, the quantitative mapping of the low-carbon requirement and the product instance structure is realized, and the cost analysis method is improved, A mathematical model of the cost and carbon footprint integration in each stage of low-carbon design is set up, and the correlation knowledge model based on the low-carbon structure is built by improving the performance mesh graph, establishing the intrinsic relation of the performance and the external conduction of the two, converting the logical relation, applying the primitive theory. In this paper, the effective dimension reduction of multi-dimension retrieval in low-carbon design is studied, and the multi-dimensional correlation function construction and application method of the case retrieval are put forward. Aiming at the problem that the calculation result of the point-to-region spacing value retrieved by the single-dimensional low-carbon requirement is not consistent with the actual design situation, the lateral distance is improved by the variable slope principle, the analogy method is applied, the multi-dimensional side distance is established, the relative complexity and the non-reducing property calculated for the multi-dimensional side distance formula are calculated, In this paper, a multi-dimensional correlation function model and its fast dimensionality reduction algorithm are constructed. Three-level low-carbon case retrieval method based on multi-dimensional correlation function is given. In order to solve the problem of multi-level, convertibility and classification of low-carbon design features, a method for dynamic classification of low-carbon instances based on hierarchical transformation is proposed. The method comprises the following steps of: converting a similar search result of a low-carbon design requirement and an example characteristic into a conflict problem description model by using a formal modeling and reasoning method, combining a similar primitive intercept set and a BP neural network, and giving a low-carbon example classification principle and a classification conduction transformation response thereof, According to the dynamic change of the low-carbon design demand, the multi-level and multi-class classification reasoning method of the low-carbon design of the multi-dimensional correlation function transformation is established. Aiming at the conflict problem of incomplete matching of low-carbon design examples, an integrated TRIZ and extension low-carbon design conflict coordination method is proposed, a transition flow of the conflict core problem and a non-nuclear problem is established, a TRIZ theory and an extension method are combined to generate an incompatible problem policy generation based on the physical contradiction, Based on the technology-contradiction-based conflict policy generation method, a low-carbon design conflict coordination process model is constructed, and a calculation method for coordinating key steps and important parameters is provided, and a design scheme of conflict coordination is realized. and finally, the above theoretical method is applied to the PLCD prototype system of the large screw air compressor, the low-carbon database construction of the multi-factor modeling technology, the mechanism analysis and determination of the low-carbon design conflict problem, the low-carbon case classification technology, The feasibility and effectiveness of the theory and method of the nuclear issue and the non-nuclear issue conversion, the emerging technology of the conflict coordination scheme, the evaluation of the scheme and the like under the low-carbon demand are discussed.
