this paper presents a strategy for using harmony search algorithm in facility layout optimization problems. in this paper an adapted harmony search algorithm is developed for solving facility layout optimization problems. this method finds an optimal facility arrangement in an existing layout. two real-world case studies are employed to demonstrate the efficiency of this model. a comparison is ...

In this study, we have classified different types of problems which are related to facility planning and layout design for different types of manufacturing processes. The main problems which are related to location of facilities which also affects the system performance such as distribution of man, material and machine in a plant or a factory and their optimization technique while using of math...

s of the Presentations Solving inconsistencys preserving the zero-structure Paula Amaral, Joaquim Júdice and Hanif Sherali, University of Coimbra In this talk we describe an nonlinear optimization model for correcting an inconsistent linear system. By correction we mean a perturbation of both the matrix of coefficients and right-hand-side of the linear system of inequalities. Inconsistency of a...

The main characteristic of today’s manufacturing environments is volatility. Under such a volatile environment some parameters like demand is not stable. To operate efficiently under such environments, the facilities must be adaptive to change production requirements. From a layout point of view, this situation requires the solution of the dynamic layout problem (DLP). Layout design has a signi...

This paper offers an approach that could be useful for diverse types of layout problems or even area allocation problems. By this approach there is no need to large number of discrete variables and only by few continues variables large-scale layout problems could be solved in polynomial time. This is resulted from dividing area into discrete and continuous dimensions. Also defining decision var...

Plant layout design is related to the location of facilities (e.g. machines, departments) in a plant. They are known to greatly impact the system performance. Numerous research works related to facility layout have been published. A few literature reviews exist, but they are not recent or are restricted to certain specific aspects of these layout design. The literature analysis given here is re...

This paper experiments application of different heuristic approaches to a real facility layout problem at a furniture manufacturing company. All the models are compared using AHP, where a number of parameters of interest are employed. The experiment shows that formal layout modelling approaches can be effectively used real problems faced in industry, leading to significant improvements.

20 Having a significant impact on the design of many products and industrial systems, such as the subdivi21 sion of a ship, the layout of facilities in a plant or further still the assembly of parts of a mechanism, layout 22 design optimization is at the heart of scientific issues. The design of an optimal layout solution is a critical 23 and complex task due to the increasing demands of design...

Eswar Sivaraman School of Industrial Engineering and Management Oklahoma State University, Stillwater, OK ABSTRACT This report details a new heuristic algorithm for solving quadratic assignment problems that arise in plant layout and relative location of activities/facilities. Programmed implementations of the algorithm solve very large problems in a negligible amount of time, results for which...
