Die Repräsentationsbeziehung zwischen Wählern und Parteien ist entscheidend für das Funktionieren repräsentativer Demokratien. Der Grad der gefühlten Repräsentation hat Einfluss auf den Delegationsmechanismus und die Demokratiezufriedenheit. Daher untersucht dieser Artikel das...

This paper treats the problem of setting the inventory level and optimizing the buffer allocation of closed-loop flow lines operating under the constant-work-in-process (CONWIP) protocol. We solve a very large but simple linear program that models an entire simulation run of a closed-loop flow...

The car sequencing problem determines sequences of different car models launched down a mixed-model assembly line. To avoid work overloads of workforce, car sequencing restricts the maximum occurrence of labor-intensive options, e.g., a sunroof, by applying sequencing rules. We consider this...

Purpose: The purpose of this research is to develop an optimization model of CNC turning process. The objective function of the model is to minimize processing time and carbon emission. We implemented the results of optimization with real machining application using a certain workpiece....

Purpose: This study aimed at implementing lean six sigma to evaluate the productivity and manufacturing waste in the production line of a paper company Methodology/Approach: The study is a case study in nature. The method illustrates how lean six sigma (LSS) is used to evaluate the existing...

Purpose: This paper aims at investigating the reasons for the complex and long lead time from global suppliers that causes inventory shortages. It focuses on supply chain risk management in global sourcing. This study has revealed all the specific risks of a global sourcing project and has...
