【摘要】：制造业在国民经济迅猛增长过程中起到了支柱性的作用,可以作为衡量一个国家综合实力的重要标志,但是伴随来的安全问题越来越受到社会各界的关注。虽然我国的制造业正朝着自动化、机械化、智能化的方向发展,但在实际生产中仍不可避免有大量的人工作业。生产线的作业工人作为制造业生产过程中主要参与者,是人-机-环-管理这一复杂生产系统的核心因素,受到作业强度大、作业时间长、作业难度大、生活与工作双重压力、环境恶劣、管理水平低等诸多因素的影响,这些都容易引起工人的疲劳感,主要表现为全身酸痛、工作消极、精神萎靡等症状,造成工人极易出现失误操作、生产效率下降、安全事故频发等严重后果。由此可见作业疲劳是造成制造业安全问题的重要原因,因此本文对于研究制造业工人作业疲劳影响因素问题十分有必要。本文选取了制造业生产线上的工人为研究对象,基于国内外疲劳影响因素研究现状,结合人因工程学相关理论,确定了作业疲劳影响因素的五大指标集,分别为作业人员情况、机器设备、作业本身、作业环境、组织管理,并选取了 29个指标,构建了本文的评价指标体系。然后采用发放问卷的方式对影响作业疲劳的因素进行研究,并对获得的研究数据进行信度与效度的检验。接下来运用结构方程模型研究各个指标对线上工人作业疲劳的影响机制,进行一阶和二阶验证性因素分析与运算,根据分析结果对模型进行不断的修正和拟合,以便得到拟合度高的关系结构模型。最后对本文的研究成果进行了总结,指出论文的研究局限之处,并对未来研究方向提供了一些新想法。本文根据研究结果从人员、机器、环境、组织管理的角度上提出一些对策建议,达到缓解作业疲劳和避免安全事故保障安全生产的目的,同时为后续学者的深入探究提供一定的借鉴和指导作用。
[Abstract]:Manufacturing industry has played a pillar role in the rapid growth of national economy and can be regarded as an important symbol to measure the comprehensive strength of a country. However, the accompanying security issues have attracted more and more attention from all walks of life. Although China's manufacturing industry is developing towards automation, mechanization and intelligence, a large number of manual operations are inevitable in actual production. As the main participants in the manufacturing process, the workers of the production line are the core factors of the complex production system, that is, the man-machine-ring management, which is subjected to the double pressures of work, such as high intensity of work, long working time, great difficulty in working, and double pressures of life and work. The adverse environment, low management level and many other factors can easily cause the workers' fatigue, which are mainly manifested in the symptoms of general soreness, negative work, mental depression, etc., resulting in workers' prone to misoperation and the decline in production efficiency. Frequent safety accidents and other serious consequences. It can be seen that occupational fatigue is an important cause of manufacturing safety problems, so it is necessary to study the influencing factors of manufacturing workers' work fatigue. In this paper, the workers in the manufacturing line are selected as the research objects. Based on the current research situation of fatigue factors at home and abroad, combined with the related theory of human factor engineering, the five index sets of the influencing factors of work fatigue are determined, respectively, which are the working personnel. Machine equipment, operation itself, work environment, organization and management, and 29 indicators are selected to construct the evaluation index system of this paper. Then, the factors influencing work fatigue were investigated by questionnaire, and the reliability and validity of the obtained data were tested. Then the structural equation model is used to study the influence mechanism of each index on the work fatigue of workers on line, and the first and second order confirmatory factor analysis and calculation are carried out. According to the analysis results, the model is constantly modified and fitted. In order to obtain a high degree of fitting relational structure model. Finally, this paper summarizes the research results, points out the limitations of the research, and provides some new ideas for the future research direction. According to the results of the research, this paper puts forward some countermeasures and suggestions from the point of view of personnel, machinery, environment, organization and management, in order to alleviate the work fatigue and avoid the safety accidents to ensure the safety of production. At the same time for the follow-up scholars to explore the depth of a certain reference and guidance.
