Virtual cellular manufacturing system based on resource element approach and analyzing its performance over different basic layouts

Abstract

This research aims to present how choosing a suitable layout can improve the performance of virtual cellular manufacturing systems (VCMSs), especially minimizing the material flow between machines required by each family group. To present the efficacy of basic layouts on performances of VCMSs, a multi-objective mathematical model with a goal programming (GP) approach is developed to generate VCMSs based on resource-elements (REs). The formulated model is coded in Lingo software and is run over functional and distributed arrangements of the same machines. The performance and the validity of the developed model are checked by a numerical example taken from the literature. The objective function of the mathematical model is measured for that example over two mentioned layout to compare the performance of the generated systems. Moreover, because of the material handling costs importance, material flows are measured to find the best option as a basic layout for VCMSs. To compare the performance of the generated system with the classical cellular manufacturing system (CMS), cell capacity utilization (CCU) is employed as an independent criterion to evaluate each system. The result illustrates the priority of distributed layouts for generating RE-based VCMSs because of its flexibility, minimizing the objective function for the mathematical model, and smaller material flow by the components. In addition, the generated VCMSs outperforms the classical CMS from the CCU point of view.

Comparação dos projetos fatoriais completo e fracionado em um modelo de simulação de eventos discretos em um sistema de manufatura para os leiautes celular e celular virtual

“…Reaes ( 2008) cita que na comparação entre os leiautes celular virtual e tradicional a ocupação dos operadores foi maior no leiaute celular tradicional, porém nesta pesquisa consideraram-se, além dos operadores, todos os recursos do leiaute, as máquinas e os movimentadores, resultando num resultado global superior do leiaute virtual. O melhor desempenho do celular virtual nesse estudo concorda com Hamedi et al (2012aHamedi et al ( , 2012c.…”

RE-Based Weighted Distributed Equipment Layout

“…Especially on the average total transportation distance and the total flow time, distributed layout is absolutely superior to functional layout. Hamedi (2011) [9] proposed a distributed layout designing method by considering equipment processing capacity, minimize parts transportation distance and maximize the effective utilization of the equipment.…”
