Detailed Dynamic Layout Planning: An Adaptive Layout Approach

Abstract

Layout planning deals with the arrangement of facilities in a plant. Layout planning is said to be dynamic when the problem deals with the design of multi period plan with changes in demand. This paper formulates the dynamic layout problem as a quadratic assignment problem. An adaptive approach is considered to solve the problem. Simulated annealing is proposed for the development of solution in the form of a block plan for the dynamic plant layout problem. Addition of details such as flow plans, aisle width, department input /output location, etc. to the block plan gives a new detailed layout called net aisle and department layout. An integer linear programming model is used for the formulation of this detailed layout. A LINGO program is developed to solve the model. Net aisle and department layout provide a more realistic layout than a block layout with a better estimation of material handling cost.
