An Approximation Method for Fuzzy Fixed-Charge Transportation Problem

In this paper, we develop the fuzzy fixed charge transportation problem when the costs are the fuzzy numbers. The first step it transform into the classical fuzzy transportation problem. The next, we obtain the best approximation fuzzy on the optimal value of the fuzzy fixed-charge transportation problem. This method obtains a lower and upper bounds both on the fuzzy optimal value of the fuzzy ...

Method for Conceptual Design Applied to Office Buildings

The paper presents a computer-based method for the multicriteria conceptual design of engineered artifacts. The proposed method involves genetic-based stochastic search, Pareto optimization, and color-filtered graphics. A multicriteria genetic algorithm broadly searches the governing body of design knowledge and identifies Pareto designs that are equal-rank optimal in the sense that each is not...

Building information modelling for sustainability appraisal of conceptual design of steel-framed buildings

Stiffness-based Approach for Preliminary Design of Framed Tube Structures

A parametric formulation for preliminary design of tubed-system tall buildings is presented in which some optimality criteria and practical constraints are considered. Here, a minimum compliance optimization formulation, developed by other researchers, is applied to a framed-tube structure. The tube behavior is modeled as a cantilevered box beam. Independent variable in this problem is thicknes...

Extension of Direct Displacement-Based Design to Plan-Asymmetric RC Frame Buildings

The object of this paper is the evaluation of the seismic response of reinforced concrete frames designed according to the DDBD (direct displacement-based design) approach. The great part of research works about DDBD has been dedicated to planar frames, but recently also some proposals for 3D structures have been presented, in particular for wall structures. This paper will give a further contr...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
