A study of the connection between lean manufacturing and ergonomics

If an organization implements lean manufacturing without concurrently considering ergonomic requirements, the anticipated outcome, such as increased production productivity, may not be realized. Several authors have emphasized the significant potential for synergies resulting from the successful integration of lean manufacturing and ergonomics. The objective of this paper is to exemplify the application of lean manufacturing tools in enhancing the productivity of casting aluminium alloys while incorporating ergonomic considerations. The results of the assessment of working positions through the CERAA application before intervention indicate a potential risk of increased physical strain on operator. Utilizing a hybrid research design, we conducted a singular case study that delves into the industrial implementation of a robotic cell in the production line for manufacturing battery covers for electric/hybrid vehicles. The results of the assessment of working positions after the implementation of robotic technology do not indicate a potential risk of increased physical load on the operator. This case study demonstrates the integration of ergonomics and lean manufacturing principles in practice.
