Application of fuzzy decision-making in facilities layout planning

Abstract

This paper establishes a vigorous methodology, based on the fuzzy set theory, to improve the facilities layout process that has occupied scholars and practitioners for more than four decades. Fuzzy set theory is an appropriate 1001 which uses the natural language that humans use to control complex systems such as facilities planning. The closeness rating between departments in a plant depends on qualitative and quantitative factors. Sonie of these factors may have greater effect on the designer's decisions about such ratings. Thus, the pairwise comparison of the analytical hierarchy process (AHP), which ensures the consistency of the designers' decisions when assigning the importance of one factor over another, is used to find the weights of these factors. FUZZY? a computer program developed based on the fuzzy decision-making system (FDMS) is used to generate the activity relationship charts. These charts are used by FZYCRLP. a modified version of CORELAP. to develop the layouts. FELAP. another program based on FDMS is used to evaluate the layouts. The new evaluation method uses [he distances and the relationships between departments to score the layout. The scoring system, which ranges from zero to ten (ten is the best possible score), can be used to evaluate and compare any layout regardless of the number of the departments and their size.

El WIP como objetivo estratégico en la distribución de planta

“…Entre los primeros se encuentran: minimizar el costo del espacio; minimizar el costo de manejo de materiales; minimizar el costo de reorganizar (Hicks & Lowan, 1976), minimizar el backtracking y el bypassing (Braglia, 1996), minimizar la congestión del flujo de material (Afentakis, 1989), minimizar las irregularidades de forma (Meller, Narayanan, & Vance, 1998) y maximizar las adyacencias. También existen artículos que consideran más de un objetivo simultáneamente (Dweri & Meier, 1996), que proponen un modelo que minimice, a la vez, el flujo de materiales y de información. En los objetivos cualitativos se encuentran la seguridad de la planta, la flexibilidad de la distribución, el ruido y la estética (Singh & Sharma, 2006).…”

A simulation approach to facilitate manufacturing system design

“…They use simulation to study the dispatching rule optimization with random process time. Dweiri and Meier [8] also investigated the application of fuzzy sets theory in facilities layout planning. Longo et al [9] performed material flow analysis and used a simulation approach to optimize the plant lay-out of a manufacturing system.…”

Intelligent systems in manufacturing: current developments and future prospects

“…Precise estimations of these parameters are difficult. Dweiri and Meier(1996), defined a fuzzy decision-making system (FDMS) consisting of four principle components:…”
