Manufacturing industries these days are more concerned about the energy consumption due to the increasing energy cost. It is observed that industries can achieve significant savings in the energy cost even when a small percentage of energy consumption is reduced. In a manufacturing industry, assembly lines are equipped with robots to perform the assembly tasks and there is a need for efficiently balancing the assembly line by reducing the energy consumption during the production phase. The authors could not find any research on optimizing energy consumption in U-shaped robotic assembly line systems to date. The objective of this paper is to propose an optimization models with an objective of minimizing the energy consumption in a U-shaped robotic assembly line when the number of workstations are fixed. Since the assembly line balancing problems falls under the category of NP-hard, an efficient bio inspired algorithm is implemented to solve the problem. The model proposed is very well applicable for automobile assembly line where robots are employed. The energy consumption is evaluated on the benchmark data and energy consumption obtained by the U-shaped robotic assembly line is compared with the energy consumption obtained with straight robotic assembly line. The cycle time of the layouts are also compared. The results obtained using this proposed model can be used for the decision making process in the industry. The paper also proposes an optimization model for minimizing the cycle time. The energy consumption of the assembly line when the cycle time is minimized is evaluated and presented.

OtherWelcome to the ICAMechS 2015 homepage! The 2015 International Conference on Advanced Mechatronic Systems (ICAMechS 2015) will be held in Beijing, China on August 22-24, 2015. This conference is sponsored by Beijing Univ. of Posts and Telecommunications, Tokyo University of Agriculture and Technology, and IEEE Systems, Man, and Cybernetics Society. International Journal of Advanced Mechatronic Systems (IJAMechS), International Journal of Modelling, Identification and Control, The Institute of Complex Medical Engineering, The Society of Instrument and Control Engineers, and The Institute of Systems, Control and Information Engineers are patrons of the conference. It provides an international forum for professionals, academics, and researchers to present latest developments from interdisciplinary theoretical studies, computational algorithm development and applications of mechatronic systems. It particularly welcomes those emerging methodologies and techniques which bridge theoretical studies and applications in all mechatronic systems. Novel quantitative engineering and science studies may be considered as well. Conference content will be submitted for inclusion into IEEE Xplore as well as other Abstracting and Indexing (A&I) databases. On behalf of the Organizing Committee, we would like to invite you to participate in this exciting event.
