We consider facility layout problems, where mn facility units are assigned into mn cells. These cells are arranged into a rectangular pattern with m rows and n columns. In order to solve this cell type facility layout problem, many approximation algorithms with improved local search methods were studied because it was quite difficult to find exact optimum of such problem in case of large size problem. In this paper, new algorithms based on Simulated Annealing (SA) method with two neighborhood generation methods are proposed. The new neighborhood generation method adopts the exchanging operation of facility units in accordance with adjacent preference. For evaluating the performance of the neighborhood generation method, three algorithms, previous SA algorithm with random 2-opt neighborhood generation method, the SA-based algorithm with the new neighborhood generation method (SA1) and the SA-based algorithm with probabilistic selection of random 2-opt and the new neighborhood generation method (SA2), are developed and compared by experiment of solving same example problem. In case of numeric examples with problem type 1 (the optimum layout is given), SA1 algorithm could find excellent layout than other algorithms. However, in case of problem type 2 (random-prepared and optimum-unknown problem), SA2 was excellent more than other algorithms.

The demise of the native franchise markets and the emergence of competitive markets in electricity generation service is substantially altering the way that operation and planning activity is conducted and is making it increasingly difficult for market participants such as generation firms to prospect the future electricity markets. Traditional generation expansion planning (GEP) problems which centrally determine the least-cost capacity addition plan that meets forecasted demand within pre-specified reliability criteria over a planning horizon (typically 10 to 20 years) is becoming no more valid in competitive market environments. Therefore, it requires to develop a new methodology for generation investments, which is applicable to the changed electric industry business environments and is able to address the post-privatization situation where individual generation firms seek to maximize their return on generation investments against uncertain market revenues. This paper formulates a new generation expansion planning problem and solve it in a market-oriented manner.

The purpose of this study was to understand the new generation's culture and to analyze if the characteristics of their lifestyle is significant for the study of new generation's fashion. The new generation's characteristics of lifestyle can be described as a strong pride of their own self and the life which expresses that pride. To analyze this characteristics connecting it with fashion, it is as follows: -It is the egocentric sensitivity culture. In their fashion, there appears a tendency that sense and individuality are counted much rather than fashion. -Diverse fashion information is gained through the mass media and communication. The sense for fashion is liable to change according to the circumstances and, simulated world is made. -The sense of denial is not shown much to the western lifestyle and way of thinking owning to the international open culture. Their consciousness and favorite of fashion are beyond the border. The new generation showed the unprecedent way of expression, denying the established form, and this is defined as Borderless fashion. The Borderless fashion leads a whole trend of new generation's fashion in the late part of ninties. Two typical trends appear as Genderless look for the individualic group and Romanticism look laying stress on womanliness.
