This paper discusses 2 heuristic job rotation procedures for preventing industrial workers from being excessively exposed to ergonomics and safety hazards in their workplaces. The objective of the procedures is 2-fold: (a) to find a minimum number of workers required for the given set of jobs, and (b) to determine a set of safe worker-job-period assignments such that all workers' exposure to hazard does not exceed the permissible limit. Here, occupational hazards are divided into 2 categories: single- and variable-limit hazards. In the first category, workers are considered to have equal capability to withstand the hazard; in the second category, the limit of hazard exposure varies for different individuals. Numerical examples are presented to demonstrate the procedures.
本文讨论了两种启发式工作轮换程序，以防止产业工人在工作场所过度暴露于人体工程学和安全危害之中。这些程序的目标有两个：（a）为给定的一组工作找到所需的最少工人数量，以及（b）确定一组安全的工人-工作-时间段分配方案，以使所有工人面临的危害不超过允许限度。在此，职业危害分为两类：单限值危害和变限值危害。第一类中，工人被认为具有同等承受危害的能力；第二类中，不同个体的危害暴露限值各不相同。文中给出了数值示例以演示这些程序。
