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 ...

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 syste...

Increasing global competition has enforced all members of supply chains to optimize their activities to achieve high performance and customer satisfaction. A company can improve its supply chain performance in terms of responsiveness and efficiency by means of good facility layout design. Facilities are the places in the supply chain network where product is stored, manufactured, assembled or f...

A tree structure model has been proposed for representing the unequal-area facility layout. Each facility has a different rectangular shape specified by its area and aspect ratio. In this layout problem, based on the assumption that the shop floor has enough space for laying out the facilities, no constraint is considered for a shop floor. Objectives are minimizing total part movement between f...

Parallel genetic algorithms techniques have been used in a variety of computer engineering and science areas. This paper presents a parallel genetic algorithm to solve the geometrically constrained site layout problem that involves coordinating the use of limited space to accommodate temporary facilities subject to geometric constraints. The algorithm is parallelized based on a message passing ...

— Facilities layout is a systematic and functional arrangement of different departments, machines, equipments and services in a manufacturing establishment. It is vitally important to have a well developed plant layout for all the available resources in an optimum manner and get the maximum out of the capacity of the facilities. The problem is of particular importance for Small and Medium Enter...

Development of application front-ends that are designed for deployment on multiple devices requires facilities for specifying deviceindependent semantics. This paper focuses on the user-interface requirements for specifying device-independent layout constraints. We describe a device independent application model, and detail a set of high-level constraints that support automated layout on a wide...

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...
