Using IPS software for decision making when developing a collaborative work station : A simulation-based case study in the remanufacturing industry

Abstract: European manufacturing companies are facing challenges of increasing prices of raw material, more customized products and competitiveness from industries outside Europe. Those challenges make the manufacturing require flexible production processes. The remanufacturing industry has the advantages of produce products using less raw material and to a lower cost compared with manufacturing. This makes the remanufacturing industry a way for the European companies to stay competitive. Challenges of the remanufacturing process are the operator exposure of vibrations, monotony tasks and ergonomic issues when disassembling the incoming core. To meet the challenges and stay competitive the Swedish manufacturing industries is currently examine the advantages of collaborative robots and how implementation of collaborative robots can improve production. Implementation of a collaborative robot at a workstation requires risk assessment as human safety is an important aspect to consider. Simulation modelling can advantageously be used to examine future state scenario or investigate how a current system is affected by different variables. To meet the challenges described the aim of this thesis has been to examine how to facilitate the design of a collaborative disassembly workstation by means of simulation. The work with the thesis is based on a case study made at a Swedish remanufacturing company. Following research questions has been formulated to fulfil the purpose:
