摘 要:近年来，我国媒体对“过劳”的报道日益增多，再次引发了人们对“疲劳”问题的深切关注。虽然有关问题的研究已经进行了几十年，但针对“作业疲劳”还有一些基本问题和核心问题并没有得到很好地解决，引发越来越多的健康隐患和安全事故。近年来。随着食品加工企业的迅猛发展，产业工人的作业疲劳成为一个突出问题。本文以昆明某食品加工企业为例，围绕食品加工包装作业过程中的诸多问题，从人因工程的角度展开研究，掌握员工作业疲劳概况，探究并归纳影响食品包装工人作业疲劳的因素。主要通过观测法、问卷调查等方法，对该企业厂房内部的色彩问题、照明问题和作业空间问题等进行实地调查。在此基础上，从预防与缓解疲劳、改进色彩和照明的设计以及改善作业空间这几个方面提出相应的改善措施。本研究选择这个课题，开展基于人因工程学的作业疲劳研究，旨在降低人体疲劳度以保证安全生产和提升作业效率，同时促进该行业作业环境的改善，为食品加工企业进行现场作业的人因改进提供了方法论支持，从而保障员工的职业安全和健康。

ABSTRACT:In recent years, China's media reports on the "strain" increasingly, the resurgence in deep concern of "fatigue" problem. Although studies of problems has been underway for decades, but on "homework fatigue" and some basic problems and the core problem and haven't been solved very well, cause more and more health problems and accidents. In recent years. With the rapid development of food processing enterprises, industrial workers homework fatigue has become a prominent problem. A food processing enterprise as an example, based on Kunming around food processing packaging homework problems in the process, from the perspective of people because of engineering study, grasp the operator fatigue situation, to explore and factors influencing the food packaging workers work fatigue. Mainly through methods such as observation method, questionnaire survey, the enterprise internal plant color, lighting and space problems such as field investigation. On this basis, from prevention and to alleviate fatigue, improve color and lighting design and improving operation space this several aspects put forward the corresponding improvement measures. Select this topic, this study carried out based on the homework fatigue of human factors engineering research, aimed at reducing the body fatigue to ensure safe production and improve working efficiency, and promote the improvement of working environment, the industry for food processing enterprises to carry out on-site for improvement provides a methodology to support, to ensure the employee's occupational safety and health.
