“…2 Material handling costs are one of the most crucial factors to measure the rationality of a layout since they account for 20%-50% of the overall operating costs and 15%-70% of the total manufacturing costs. 3 A rational facility can significantly improve the overall productivity and production efficiency and can reduce production cycles. 4 In turn, a poor facility layout may cause the accumulation of the WIP inventory, overloading of the material handling system, and longer queues.…”

Dynamic facility layout problems involve devising the optimal layout for each different production period. This article studies unequal-area dynamic facility layout problems under fuzzy random environment to minimize the sum of the material handling costs and rearrangement costs. For a more general situation, a novel model of unequal-area dynamic facility layout problems is proposed on the basis of fuzzy random theory, in which uncertain demands are characterized by fuzzy random variables. Unequal-area dynamic facility layout problems are one of the non-deterministic polynomial-time hard problems. Therefore, a hybrid particle swarm optimization and simulated annealing algorithm is innovated to solve the proposed unequal-area dynamic facility layout problems model under fuzzy random environment, in which the shapes and areas of facilities are changed dynamically. Two facility-swapping methods and two local search methods help hybrid algorithm escape from local optima, allowing a more reliable solution. Moreover, a new shifting method is developed to prevent the spatial overlapping between adjacent facilities and save material handling costs. The performance of the hybrid algorithm is confirmed by some test problems available. Finally, the proposed method is extended to a facility layout planning of a new aircraft assembly shop floor. Computational results show that the efficiency and effectiveness of the proposed method, in sharp comparison with other approaches.

This research discusses the redesign of facility layout on metal smelting SMEs that experienced changes in the type of products produced due to shifting consumer needs. Changes in the type of product produced affect the flow of the production process and result in decreased productivity. This study aims to redesign facilities adapted to the type of product produced. Re-layout processes using the conventional method is started by making the operation process chart, drawing the initial layout, and calculate the total moment of product using the From-to Chart (FTC). By using some trial obtained a trial layout that can increase the productivity based on the total moment of the product and the number of output that can be produced. This study also determines the Cost of Production (HPP) for all metal casting products and compares them with previous conditions. This study shows that by re-layout, the output will be greater and the cost of production is cheaper.

Design of a robust production facility layout with minimum handling cost (MHC) presents an appropriate approach to tackle facility layout problems in a dynamic volatile environment, in which product demands randomly change in each planning period. The objective of the design is to find the robust facility layout with minimum total material handling cost over the entire multiperiod planning horizon. This paper proposes a new mathematical model for designing robust machine layout in the stochastic dynamic environment of manufacturing systems using quadratic assignment problem (QAP) formulation. In this investigation, product demands are assumed to be normally distributed random variables with known expected value, variance, and covariance that randomly change from period to period. The proposed model was verified and validated using randomly generated numerical data and benchmark examples. The effect of dependent product demands and varying interest rate on the total cost function of the proposed model has also been investigated. Sensitivity analysis on the proposed model has been performed. Dynamic programming and simulated annealing optimization algorithms were used in solving the modeled example problems.
