Framework for Part Families Associated with Setup Sequence Based Similarity in Reconfigurable Manufacturing System / Cellular Manufacturing System

Abstract

The configurations of reconfigurable manufacturing system (RMS) evolved around market requirements and corresponding manufacture capabilities, exploiting all available resources. Similar products / parts families are grouped together and requires a specific manufacturing configuration in term of setups and respective tools changes in RMS. The recognition of minimum number of setup changes in multi parts production and its application for part family formation is an important step in RMS. In the present work, a novel method has been developed for recognition of minimum number of part setups with tool change options for calculation of similarity relation of parts, keeping in view the precedence constraints, machining constraints and good manufacturing practices. Bypass moves and idle machines in setup sequencing (BMIMS) similarity coefficient based on setup sequence of parts has been developed on the basis of Longest common subsequence (LCS) for setup sequences. The developed coefficient of similarity was compared for analysis with the existing similarity/distance coefficients, already available in literature. The average linkage clustering algorithm has been applied for classification of example parts using this similarity coefficient. The developed methodology is useful for RMS as well as for cellular manufacturing system.

Design for Sustainability and Reconfigurable Manufacturing Systems - An Critical Analysis

“…When the performance of the result proposal does not meet the specifications, designs are discarded and novel proposals are produced (6). As such, the remedy proposal becomes the candidate remedy (7,8). Mechanical firms utilize CAx framework to underpin the evaluation of the remedy proposal as shown in the striped part in Fig 1 . CDS-centered frameworks can extend the dimension of computational support of the wide-range activities of design evaluations and synthesis.…”

“…Consequent to that, the adaptability and architecture of RCMS provides the designers of engineering system a widerange of chances to influence and design the performance of the system model that makes the model suitable for mitigating future uncertainties [7]. Nonetheless, high adaptability also establishes the opportunity of not utilizing the potential of manufacturing assets.…”
