Determination of facilities, such as factories or warehouses, location and availability conditions is one of the important and strategic decisions for an organization to make. Transportation costs that form a major part of goods price are dependent to this decision making. There are verity of methods have been presented to achieve the optimal locations of these facilities which are generally de...

This paper presents a new approach to the pagination problem. This problem has traditionally been solved ooine for a variety of applications like the pagination of Yellow Pages or newspapers, but since these services have appeared in Internet, a new approach is needed to solve the problem in real time. This paper is concerned with the problem of paginating a selection of articles from web newsp...

recently, much attention has been given to stochastic demand due to uncertainty in the real -world. in the literature, decision-making models and suppliers' selection do not often consider inventory management as part of shopping problems. on the other hand, the environmental sustainability of a supply chain depends on the shopping strategy of the supply chain members. the supplier selection pl...

Recent facility location allocation problems are engaged with social, environmental and many other aspects, besides cost objectives.Obtaining a sustainable solution for such problems requires development of new mathematical modeling and optimization algorithms. In this paper, an uncapacitated dynamic facility location-network design problem with random budget constraints is considered. Social i...

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 ...

This work introduces an algorithm that uses simulated annealing to perform electronic component layout while incorporating constraints' related to thermal performance. A hierarchical heat transfer analysis is developed which is used in conjunction with the simulated annealing algorithm to produce final layout configurations that are densely packed and operate within specified temperature ranges...

The paper presents a new powerful technique to linearize the quadratic assignment problem. There are so many techniques available in literature that used In all these linear formulations, both number of variables and constraints significantly increase. problem (QAP) is well-known whereby set facilities allocated locations such way cost function distance flow between facilities. this problem, co...

This paper investigates the irregular shape packing problem. The proposed algorithm constructively creates layouts from an ordered list of items and a placement heuristic. A moveable item is exclusively placed on a collision free region vertex. The container has a fixed width, while its length can change so that all items are placed on it. The objective is to find a layout of the set of items t...

We consider the facility layout problem with machine capacities (and hence multiple machines of each type) and random demand. We develop a very efficient heuristic allowing us to find good solutions to the stochastic case whenever good solutions can be found for the corresponding deterministic problem with uncapacitated machines of the same dimension. Hence, this problem represents a case where...
