TWO-PHASE DYNAMIC FACILITY LAYOUT METHOD USING ESs
نویسندگان
چکیده
A lot of Metaheuristics for solving dynamic combinatorial facility layout problems have been developed, but still require much computation time when the number of facilities or planning horizon is large. Dynamic facility layout should meet a dynamic change in both product mix and demand quantity of each product over a planning horizon by adjusting facility layout effectively under a given system capability. This paper improves the performance in the previous dynamic layout method based on Evolution Strategies (ES), by elaborating a technique for adjusting weights on a penalty term corresponding to overlapped area of any two facilities in the fitness function and by incorporating a recombination mechanism in addition to the usual mutation procedure in ES. Some numerical experiments make clear that the improvement rate by the proposed method is very high.

Performance Analysis of Dynamic and Static Facility Layouts in a Stochastic Environment
In this paper, to cope with the stochastic dynamic (or multi-period) problem, two new quadratic assignment-based mathematical models corresponding to the dynamic and static approaches are developed. The product demands are presumed to be dependent uncertain variables with normal distribution having known expectation, variance, and covariance that change from one period to the next one, randomly...

A facility layout problem is concerned with determining the best position of departments, cells, or machines on the plant. An efficient layout contributes to the overall efficiency of operations. It’s been proved that, when system characteristics change, it can cause a significant increase in material handling cost. Consequently, the efficiency of the current layout decreases or is lost and it ...

This paper aims at proposing a quadratic assignment-based mathematical model to deal with the stochastic dynamic facility layout problem. In this problem, product demands are assumed to be dependent normally distributed random variables with known probability density function and covariance that change from period to period at random. To solve the proposed model, a novel hybrid intelligent algo...

The dynamic facility layout problem (DFLP) is the problem of finding positions of departments onthe plant floor for multiple periods (material flows between departments change during the planning horizon)such that departments do not overlap, and the sum of the material handling and rearrangement costs isminimized. In this paper a new optimization algorithm inspired from colonizing weeds, Invasi...

The dynamic facility layout problem involves the design of facility layouts in which the flows of materials between activities can change during a multi-period planning horizon. In the static layout problem, it is assumed that all the activities are constant. However, in today’s volatile markets, the business conditions are changing. So the similar changes are imposed on the facility projects a...
