Abstract
The purpose of this study is an understanding of operator work in a production line and its connection and translation into simulation. A mapping of operator work in the production line was performed, after which tasks and were analysed for their relevance for simulation. A model draft was developed in the software FlexSim. The mapping and the derived model provides insight into operator work in the current production line, which can be used for future development and planning. Challenges and limitations in task mapping and modelling are discussed. The scope of the study is limited to mapping and modelling of operator work in the finishing line during normal production activities, with focus on the KPI of throughput, EE and operator... (More)
The purpose of this study is an understanding of operator work in a production line and its connection and translation into simulation. A mapping of operator work in the production line was performed, after which tasks and were analysed for their relevance for simulation. A model draft was developed in the software FlexSim. The mapping and the derived model provides insight into operator work in the current production line, which can be used for future development and planning. Challenges and limitations in task mapping and modelling are discussed. The scope of the study is limited to mapping and modelling of operator work in the finishing line during normal production activities, with focus on the KPI of throughput, EE and operator utilisation. No time studies are performed.
Some key concepts in operator simulation are identified as operator availability, critical aspects of tasks (deadline for completion or set time for execution), operator dependency and cooperation. It is concluded that operator simulation can be used to understand operator utilisation and its connection to system throughput in the studied production line. The main challenges are related to understanding the properties of tasks, to modelling of operator availability, critical aspects and cooperation, and to interpretation of the results. The limitations are related to cooperation and the fact that not all tasks can, or should, be modelled. (Less)
