These facts (greater accounting for total variance and shaper delineation of principal components) should encourage the application of fuzzy principal components analysis methodology to other areas. Using fuzzy principal component analysis, it is possible to explain some of the discrepancies, found in the literature, relating to multivariate analysis of data in terms of efficiency, goodness-of-fit, predictive power and robustness. 11 Mathematical Iterative Search Methods Iterative search techniques may be described in terms of their structures, computational procedures, and important decision problems formulated as minimization or maximization of a mathematical function of several variables having a number of constraints.

Therefore, in order to achieve the absolute minimum energy state, the temperature needs to be reduced at a slower rate. The SA algorithm simulates this process of slow cooling of molten metal to achieve the minimum function value in the minimization problem. The cooling phenomenon is simulated by controlling a temperature like parameter introduced with the concept of Boltzman probability distribution. According to Boltzman probability distribution, a system in a thermal equilibrium at a temperature ‘‘T’’ has its energy distributed probabilistically according to the following expression: PðEÞ ¼ expðÀE=KT Þ ð1:47Þ where ‘‘K’’ is Boltzman constant.

Accordingly, pheromone concentration associated with each possible route (variable value) is changed in a way to reinforce good solutions, as follows: Cij ðtÞ ¼ qCij ðt À 1Þ þ DCij ; t ¼ 1; 2; . .. ; T ð1:52Þ where T is the number of iterations (generation cycles); Cij(t) is the revised concentration of pheromone associated with option lij at iteration t, Cij (t - 1) is the concentration of pheromone at the previous iteration (t - 1); DCij = change in pheromone concentration; and q = pheromone evaporation rate (0–1).
