Designing multi-workday noise-safe job rotation schedules based on skill and demand requirements
Abstract:
Job rotation is a timely and cost-effective management approach, widely used for noise exposure mitigation. This thesis aims to improve the practicality of job rotation methodology by considering the following important characteristics of manufacturing systems. First, the ability of job rotation to control noise exposure, while achieving key manufacturing requirements and objectives, is addressed. Second, the effects of job rotation on process continuity and productivity are considered. Third, this research demonstrates the capability of the proposed job rotation approach in maintaining the safety of worker over overtime and extended work hours. Integer programming is used to develop noise-safe job rotation models under cost minimization objective. Demand and skill required by tasks are formulated as constraints in the proposed model. The effectiveness of the models is evaluated under different overtime policies, levels of skilled worker availability, and levels of product demand. According to the model validation results, the proposed model is shown to remain effective in maintaining the safety of workers under scenarios where some workers are required to work overtime to fulfill the demand requirements
