Machine reconfigurability models using multi-attribute utility theory and power function approximation

Abstract

Reconfigurable Machines (RMs) are considered to be one the key elements of modern manufacturing systems like Reconfigurable Manufacturing Systems (RMSs). These machines offered customized flexibility in terms of capacity and functionality. These machines are modular machines assembled using basic/essential modules and auxiliary modules. These RMs can be reconfigured into several other configurations offering variable functionality and capacity by keeping its base modules and just adding/removing or adjusting the auxiliary modules. Measuring machine reconfigurability may be considered as one of the important parameter in assessing the performance of these manufacturing systems. In the present paper, reconfigurability models were developed using Multi Attribute Utility Theory (MAUT) and Power Function Approximation. The developed models are explained and demonstrated using multi stage serial reconfigurable product flow line. © 2013 The Authors. Published by Elsevier Ltd.
