【摘要】：煤炭是远古时期植物死亡之后,在高温高压的环境之下,经过几亿年演化,逐步形成的一种资源。自十七世纪世界各国进入蒸汽时代以来,煤炭逐渐成为世界经济发展动力的重要物资。近年来,随着科技的发展、社会的进步、煤矿安全事故的发生率呈现出逐步下降的趋势,但是中国的煤矿伤亡事故依然占到全世界的80%以上。各级政府和国家安监局通过加大安全监管的法律、制度、条例等不同手段约束煤炭生产企业对安全资源方面的投入。当然,煤炭生产企业管理者也逐步意识到生产安全的责任大于天,采取了不断增加安全资源的投入的措施来提高煤炭开采过程中的安全平。其中,有些企业通过增加对员工培训,有些企业通过采购安全的设备,还有些企业通过完善应急处置方法。但是,随着各类安全资源的不断投入,给本来就雪上加霜的煤炭生产企业的经济效益带来巨大的负担,目前,相关统计表明,中小煤炭生产企业生存艰难。另一方面,根据经济学原理,随着安全资源的投入,煤炭生产企业的生产经营效率开始会随着资源的不断投入快速增加,但是如果资本投入达到了某一程度,煤炭生产企业的生产经营效益会出现边际递减的现象。反而随着各种资源无效投入,加大了煤炭生产企业的生产经营负担,进而造成企业整体资源配置利用率的下降。基于上述现象,企业管理者为了达到煤炭生产物流中资源配置过程中提质增效的目的,继而了加大研究力度,包括聘请专业的煤矿安全研究专家对煤炭生产的各个环节的资源投入进行优化配置。本文联系煤矿行业自身的特点,为分析安全资源投入对煤炭生产行业生产物流系统资源配置效率造成的影响。首先通过文献分析法研究之前学者的研究成果,构建了煤矿生产物流系统资源配置效率评价的指标体系。其次,运用因子分析法和灰色系统关联理论确定影响煤矿生产物流系统安全水平的关键影响因子。接着,通过构建基于数据包分析(DEA)的煤矿生产物流系统资源配置效率评价模型。最后,通过中部某省某煤业集团做实证研究,以验证模型的合理性和有效性,目的是获得DEA的绩效评价方法在在煤炭生产企业中生产物流系统资源配置效率评价问题中的应用。研究结果表明,企业人员素质对安全水平的关联度为0.6941,机器设备维护因素对安全水平的关联度为0.5554,矿井环境因素对安全状态水平的关联度为0.6110,企业管理因素对安全状态水平的影响的关联度为0.7264。此外,某煤业集团投入冗余程度最大的是人力资源投入冗余,冗余水平为17.829万元。矿井环境改善投入和企业应急管理投入冗余水平分别为4.135万元和8.136万元。
[Abstract]:Coal is a kind of resource formed gradually after plant death in ancient times under the environment of high temperature and high pressure after hundreds of millions of years of evolution. Since the world entered the steam age in the seventeenth century, coal has gradually become an important material for the development of the world economy. In recent years, with the development of science and technology and the progress of society, the occurrence rate of coal mine safety accidents has gradually decreased, but China's coal mine casualties still account for more than 80% of the world. Governments at all levels and the State Safety Supervision Bureau restrict the input of coal production enterprises into safety resources through different means, such as increasing the laws, systems and regulations of safety supervision. Of course, the managers of coal production enterprises have gradually realized that the responsibility of production safety is greater than that of days, and has taken the measures of increasing the input of safety resources to improve the safety level in the process of coal mining. Among them, some enterprises through the increase of staff training, some enterprises through the procurement of safe equipment, others through the improvement of emergency disposal methods. However, with the constant investment of various kinds of safety resources, it brings a huge burden to the economic benefits of the coal production enterprises which are already aggravated. At present, the related statistics show that the small and medium-sized coal production enterprises are hard to survive. On the other hand, according to the principle of economics, with the input of safety resources, the production and management efficiency of coal production enterprises will increase rapidly with the constant investment of resources, but if the capital investment reaches a certain level, The production and management benefit of coal production enterprise will appear the phenomenon of marginal decline. On the contrary, with the invalid input of all kinds of resources, the burden of production and operation of coal production enterprises is increased, and the overall utilization ratio of resources is reduced. Based on the above phenomenon, in order to achieve the goal of raising quality and increasing efficiency in the process of resource allocation in coal production logistics, enterprise managers have increased their research efforts. Including hiring professional coal mine safety research experts to optimize the allocation of resources in all aspects of coal production. According to the characteristics of coal mine industry, this paper analyzes the influence of safety resource input on the efficiency of resource allocation of production logistics system in coal production industry. Firstly, the index system of resource allocation efficiency evaluation of coal mine production logistics system is constructed through the research results of scholars before the literature analysis. Secondly, factor analysis and grey system correlation theory are used to determine the key factors that affect the safety level of coal mine production logistics system. Then, the evaluation model of resource allocation efficiency of coal mine production logistics system based on packet analysis (DEA) is constructed. Finally, an empirical study is made by a coal industry group in the central province to verify the rationality and validity of the model. The purpose of this paper is to obtain the application of DEA performance evaluation method in the evaluation of resource allocation efficiency of production logistics system in coal production enterprises. The results show that The correlation degree of personnel quality to safety level is 0.6941, the correlation degree of maintenance factor of machinery and equipment to safety level is 0.5554, the correlation degree of mine environmental factor to safety level is 0.6110, the correlation degree of enterprise management factor to safety level is 0.7264. In addition, a coal industry group input redundancy is the largest degree of human resources input redundancy, redundancy level is 178290 yuan. The redundant level of mine environment improvement investment and enterprise emergency management is 41350 yuan and 81360 yuan respectively.
