The common Arabic keyboard layout is derived from the Arabic typewriter keyboard’s layout. This layout is not optimized for typing speed and has several problems. We use a genetic algorithm to optimize the design of the Arabic keyboard layout for typing speed. In the genetic algorithm, we use a fitness function that includes into consideration key distance, finger used, and hand alternation. We...

  A fuzzy goal programming-based approach is used to solve a proposed multi-objective linear programming model and simultaneously handle two important problems in cellular manufacturing systems, viz. cell formation and layout design. Considerations of intra-cell layout, the intra-cell material handling can be calculated exactly. The advantages of the proposed model are considering machining cos...

Introduction Various attempts have been made to apply evolutionary algorithms (EAs) to complex engineering layout designs. EAs are powerful optimisation techniques inspired by genetics and natural selection while lacking some important characteristics (prior knowledge) that make other classical and numerical search algorithms very effective. Case-based reasoning (CBR) technique is to solve the ...

In the planning phase of every construction project, layout of temporary facilities is a crucial task; site layout can affect safety, travel cost and time, construction productivity, and space utilization. However, site layout planning can be a complicated problem, due to the interdependency of influencing factors. Although interaction among activities is one of the major drivers of site layout...

The Full Adders (FAs) constitute the essential elements of digital systems, in a sense that they affect the circuit parameters of such systems. With respect to the MOSFET restrictions, its replacement by new devices and technologies is inevitable. QCA is one of the accomplishments in nanotechnology nominated as the candidate for MOSFET replacement. In this article 4 new layouts are presente...

Ž . In this paper a solution in the continual plane to the Facility Layout Problem FLP is presented. It is based on Simulated Ž . Annealing SA , a relatively recent algorithm for solving hard combinatorial optimization problems, like FLP. This approach Ž . may be applied either in General Facility Layout Problems GFLP considering facilities areas, shapes and orientations or in Ž . Machine Layou...

Facility layout is one of the most important Operations Management problems due to its direct impact on the financial performance of both private and public firms. Facility layout problem (FLP) with stochastic parameters, unequal area facilities, and grid system modeling is named GSUA-STFLP. This problem has not been worked in the literature so that to solve GSUA-STFLP is our main contribution....
