【摘要】：本论文以煤机装备为对象,以产品多生命周期理论为指导,采用改进模糊层次分析方法,研究废旧煤机装备再制造问题。本研究基于煤机装备再制造企业的尘产实践情况,对煤机装备产品多生命周期进行全面的分析、总结,梳理煤机装备再制造性评估概念体系,明确煤机装备产品多生命周期的生产流程框架结构。在此基础上,从技术、经济、环境、安全四个维度建立煤机装备再制造性评估指标体系。利用改进的模糊层次分析法建立权重矩阵,构建煤机装备再制造综合评估模型,并选取三家典型企业作为评价对象,利用煤机装备再制造性综合评估模型对其产品的再制造性进行评估。本论文的主要内容包括：(1)将产品多生命周期理论应用于煤机装备再制造性评估研究领域。以产品多生命周期理论为指导,基于煤机装备再制造企业的实践,对煤机装备产品多生命周期的全过程进行梳理、归纳、分析,明确涵盖煤机装备产品多生命周期全过程的煤机装备再制造生产流程框架,依据煤机装备再制造性评估的内涵与特征,梳理了关于煤机装备再制造性评估的概念体系。(2)研究了煤机装备产品多生命周期全过程的特点,从技术、环境、经济、安全四个维度研究影响煤机装备再制造性的关键因素,建立了煤机装备再制造性评估指标体系。论文首次将装备再制造性评估体系扩展为技术、经济、环境、安全四个维度,而以往的相关研究仅考虑了前三个维度。实证研究表明,安全可靠性在煤机装备再制造中具有重要地位,充分体现了煤矿生产中安全的重要性。(3)根据煤机装备再制造性评估指标体系,建立了煤机装备再制造性评价指标的递阶层次结构模型,利用改进的模糊层次分析法建立权重判断矩阵,构建了基于产品多生命周期理论、涵盖煤机装备多生命周期全过程的煤机装备再制造性综合评估模型。论文给出各指标的具体计算方法,对于主观性较强的指标采用模糊数进行处理,利用隶属度函数将指标值转化为模糊数。通过得到的指标权重值和评价值计算煤机装备再制造的最终评价值。(4)收集煤机装备制造业规模较大、产品种类较齐全、特色产品市场占有率较高的三家企业的相关数据对煤机装备再制造性综合评估模型的有效性进行实证研究。从二级指标综合评价结果来看,安全可行性指标比较大,环境可行性指标非常小,技术可行性指标和经济可行性指标居中。论文将评估结果与实际再制造情况进行对比,全面分析评估模型的可靠性和准确性。
[Abstract]:Based on the theory of multi-life cycle and improved fuzzy analytic hierarchy process (AHP), this paper studies the problem of remanufacture of waste coal machinery equipment. Based on the dust production practice of the coal machine equipment remanufacturing enterprise, this study comprehensively analyzes the multiple life cycle of the coal machine equipment product, summarizes, carding out the concept system of the coal machine equipment remanufacturing evaluation. Make clear the production process frame structure of multi-life cycle of coal machine equipment product. On this basis, the evaluation index system of coal machine equipment remanufacturing is established from four dimensions: technology, economy, environment and safety. Using the improved fuzzy analytic hierarchy process to establish the weight matrix, the comprehensive evaluation model of coal machine equipment remanufacturing is constructed, and three typical enterprises are selected as the evaluation objects. The remanufacturing performance of coal machine equipment was evaluated by the comprehensive evaluation model. The main contents of this paper include: (1) applying product multiple life cycle theory to the field of remanufacturing evaluation of coal machine equipment. Under the guidance of product life cycle theory, based on the practice of coal machine equipment remanufacturing enterprise, the whole process of multi-life cycle of coal machine equipment product is combed, summarized and analyzed. Defining the framework of the remanufacturing process of coal machine equipment covering the whole process of multi-life cycle of the coal machine equipment product, according to the connotation and characteristics of the evaluation of the remanufacturing performance of the coal machine equipment, Combing the concept system of remanufacturing assessment of coal machine equipment. (2) the characteristics of the whole process of multiple life cycle of coal machine equipment product are studied, and the key factors influencing the remanufacturing property of coal machine equipment are studied from four dimensions: technology, environment, economy and safety. The evaluation index system of coal machine equipment remanufacturing is established. For the first time, the paper extends the equipment remanufacturing evaluation system to four dimensions: technology, economy, environment and security, while previous researches only consider the first three dimensions. The empirical study shows that safety and reliability play an important role in the remanufacture of coal machine equipment, which fully reflects the importance of safety in coal mine production. The hierarchical structure model of coal machine equipment remanufacturing evaluation index is established, and the weight judgment matrix is established by using the improved fuzzy analytic hierarchy process (FAHP), and the multi-life cycle theory based on the product is constructed. A comprehensive evaluation model for remanufacturing of coal machine equipment covering the whole process of multi life cycle of coal machine equipment. In this paper, the concrete calculation method of each index is given. The fuzzy number is used to deal with the subjective index, and the index value is transformed into fuzzy number by membership function. The final evaluation value of coal machine equipment remanufacture is calculated by the index weight value and evaluation value.) the coal machine equipment manufacturing industry is larger in scale and more complete in product category. The data of three enterprises with high market share of characteristic products make empirical research on the effectiveness of the comprehensive evaluation model of coal machine equipment remanufacturing. From the comprehensive evaluation results of the secondary indicators, the safety feasibility index is relatively large, the environmental feasibility index is very small, the technical feasibility index and the economic feasibility index are in the middle. In this paper, the reliability and accuracy of the evaluation model are analyzed by comparing the evaluation results with the actual remanufacturing conditions.
