【摘要】：物流系统作为煤炭企业的重要组成部分，贯穿于企业整个生产过程中。现有研究多集中于针对一般性工业企业进行评价，，较少见到对煤炭企业建立单独的评价体系。而煤炭工业作为国民经济的支柱产业，其生产方式、物流系统均具有一般工业企业所不具备的特征，直接套用一般模式显然并不适用。基于此，本文针对煤炭物流系统综合评价体系开展了一系列研究。首先，对物流发展过程进行了论述，并结合物流的基本理论，对煤矿物流系统进行了分析。我国的煤炭物流系统存在物流成本较高、市场主体服务水平低、物流信息化及集成化技术落后、物流系统基础设施落后、资源配置不合理等缺陷。结合煤炭物流的特点，建立了适应煤炭行业现状、科学合理的煤炭物流系统评价指标体系。跟传统的指标体系相比，本文所建指标体系更加贴近煤炭物流系统实际情况，指标设置更加科学并富有动态性。在指标体系确定之后，采用层次分析法计算指标权重值。通过邀请专家对指标两两比较相对重要性，并通过整理形成判断矩阵，计算判断矩阵的最大特征值及特征根、一致性检验等步骤，最后得到各指标相对总目标的最终权重值。在传统模糊评价模型的基础上，针对煤炭物流系统独有的特点，建立了适当的评语集及其对应分值，并通过查阅相关文献，确定了对应的定量指标阈值，最后选用加权平均模糊算子构建了多级评价模型。最后，以北方某煤炭企业Y矿为例，对所建煤炭物流系统综合评价体系进行了验证。实例分析结果表明，所建评价体系科学合理，能较好地应用于实践中。
[Abstract]:Logistics system, as an important part of coal enterprises, runs through the whole production process. Most of the existing studies focus on the evaluation of general industrial enterprises, and less on the establishment of a separate evaluation system for coal enterprises. Coal industry as the pillar industry of national economy, its production mode, logistics system has the characteristics that the general industrial enterprises do not have, the direct application of the general model is obviously not applicable. Based on this, this paper carried out a series of research on comprehensive evaluation system of coal logistics system. Firstly, the development process of logistics is discussed, and combined with the basic theory of logistics, the logistics system of coal mine is analyzed. China's coal logistics system has some defects such as high logistics cost, low service level of the market main body, backward logistics information and integrated technology, backward infrastructure of logistics system, unreasonable allocation of resources, and so on. According to the characteristics of coal logistics, a scientific and reasonable evaluation index system of coal logistics system is established to adapt to the present situation of coal industry. Compared with the traditional index system, the index system established in this paper is closer to the actual situation of the coal logistics system, and the index setting is more scientific and dynamic. After the index system is determined, the analytic hierarchy process (AHP) is used to calculate the index weight. By inviting experts to compare the relative importance of each index, forming judgment matrix, calculating the maximum eigenvalue and root of judgment matrix, checking consistency and so on, the final weight value of each index relative to the total target is obtained. Based on the traditional fuzzy evaluation model, according to the unique characteristics of the coal logistics system, the appropriate evaluation set and its corresponding score are established, and the corresponding quantitative index threshold is determined by consulting the relevant literature. Finally, a multilevel evaluation model is constructed by using weighted average fuzzy operator. Finally, the comprehensive evaluation system of coal logistics system is verified by taking Y mine of a coal enterprise in northern China as an example. The analysis results show that the evaluation system is scientific and reasonable and can be applied in practice.
