我国纺织企业推行“四班三运转”后,减轻了工人的劳动强度,克服了连续上六个夜班的弊端,对促进生产、增强工人的身心健康都起到了良好的作用。但倒班问题无论对运转工人还是管理人员都感到不容易记,尽管各厂都以不同的形式编排了转班计划表,但由于转班频繁,仍然时有错班发生。为此,我们设计制作了一种四班三运转的“班历”,为查询倒班带来了较大的方便。这种“班历”的特点是结构简单,易于制作,携带方便,直观准确。每年只更换一次常数就可长期使用。现将这种“班历”的设计原理及使用方法简介如下。 After China’s textile enterprises implemented the “four shifts and three shifts”, they reduced the labor intensity of workers and overcame the shortcomings of the last six night shifts, which played a good role in promoting production and enhancing the workers’ physical and mental health. However, the problem of shifts is not easy to remember both for workers and managers. Although the factories all arranged shift schedules in different forms, due to the frequent shift, there were still some wrong shifts. To this end, we have designed and produced a “class calendar” with four shifts and three shifts, which brings greater convenience to the search for shifts. This “class calendar” is characterized by simple structure, easy to make, easy to carry, intuitive and accurate. Only a constant replacement can be long-term use. Now this kind of “class calendar” design principles and methods of use are as follows.
