“…The general trend of the literature in job rotation‐scheduling is to take into account the expertise level of employees (Hochdörffer et al, 2018, Moussavi et al, 2018, 2019; Wongwien & Nanthavanij, 2017). We, therefore, paid great attention to the skill/expertise level of employees in our developed models.…”

“…They integrated their mathematical model with RULA, which is one of the ergonomic risk assessment approaches. Moussavi et al (2018) handled the job rotation problem on a multiobjective basis. They assigned workload points from 1 to 10 to the tasks and included them in the developed model.…”

“…Although this situation actually points to the protection of an employee ergonomically, it contradicts with classical scheduling purposes. This constraint is one of the basic assignment constraints, and it was adapted from the paper of Moussavi et al (2018).

Job rotation schedules are generally conducted without considering hand–arm vibration (HAV) exposure especially in manufacturing firms, such as heavy industry, which confront ergonomic risks easily. This does not create any occupational health and safety (OHS) issues in the short term; however, certain occupational diseases such as the white finger disease are inevitable in the long‐term. This paper investigates how the risks of developing HAV‐related occupational diseases can be minimized by producing optimal job rotation schedules using ergonomic mathematical models. In the proposed models, both ergonomic and traditional aspects of manufacturing environments are considered. Moreover, the skill level and workers' day off preferences are also considered for total system efficiency. The mixed‐integer programming approach is used to formulate the models. The applicability of the models is tested using real‐world data. It is seen that the total assignment cost of the models increases when the ergonomic aims are included in the models. Thus, there is a conflicting relationship between economic and ergonomic aims. The main findings of the models show that the employees' HAV exposure level can be kept under control with one simple constraint. By employing these models, employees and employers can be protected in terms of not only OHS but also economic issues.

“…A worker assignment job rotation problem with heterogeneous workers and jobs with different workload levels is presented by Moussavi et al, in which both productivity and ergonomic criteria are considered in the problem and a multi-objective mixedinteger mathematical model is proposed to implement an ergonomic job rotation in a production system. The computational results shown the capability of the proposed model to optimize "daily workload" and ensuring an acceptable "production time" value [12]. A model for the activity schedules design of aged workers exposed to the risk of repetitive work is developed by Botti et al, where the approach adopted is based on a bi-objective perspective.…”

In today's economic context the workforce is a crucial asset in manufacturing industries. The employee performance and productivity are affected by many factors related on one hand to the line efficiency and, on the other hand, to the well-being of the workers. On the basis of new technologies and driven by Industry 4.0 paradigms, the need of a high production rate cannot neglect the safeguarding of the workers. In case of repetitive manual tasks, workers are exposed to the risk of musculoskeletal disorders (MSDs), that can be reduced by applying ergonomics principles both in design (e.g. workstation design, equipment tools identification, etc.) and in operative phases (e.g. workload balance, tasks assignment, etc.). In the operative phase, job rotation is one of the most widespread methods for alleviating physical fatigue and reducing the stress due to repetitive tasks. However, often, job rotation strategies fail due to the lack of systematic approach or effective management of rotation schedules, being very difficult to identify an effective job rotation schedule allowing maintaining the same productivity rate. The problem is of particular interest under the perspective of the workforce aging, a social European phenomenon which is also affecting production systems performance. Designing and scheduling of human-based assembly systems require a joint evaluation of production system performance and a good balancing of MSDs risk among workers. The authors proposed a model for minimizing the exposure risk of workers involved in repetitive manual tasks, by balancing the human workloads and reducing the ergonomic risk within acceptable limits, for a given production target. Risk and its acceptability are evaluated using the RULA method, according to a mixed integer programming approach. Results shown the effectiveness of the model to identify the optimal job rotation schedules jointly achieving productivity and ergonomic risk goals.
