Preference

The practice of executing trades and other transactions by means other than the open market. For example, if one needs roofing repairs on one's house, one may select one's brother's roofing business even if it is more expensive. In securities, preference often occurs in over-the-counter trades, especially within a brokerage. Preference can, but does not always, lead to economic inefficiency.

preference

The practice of matching customers' buy and sell orders away from the primary exchange. Preferencing is opposed by the New York Stock Exchange because it claims the practice unfairly benefits brokerage firms and doesn't give customer orders the chance to see other customer orders in a public market. Compare in-house trade.

Therefore, given the preference information of linguistic term vector [ling.sub.k] = ([ling.sup.k.sub.l] ..., [ling.sup.k.sub.n]) from expert [e.sub.k] (k = 1, ..., K), the fuzzy preference relation between [c.sub.j] and [c.sub.r] is obtained as follows:
Assuming that [OMEGA]/ ~ = {[x], x [member of] [OMEGA]} is a quotient set corresponding to the equivalence relation ~, then applying Lemmas 8 and 9, we get that the order relation [less than or equal to] in quotient set [OMEGA]/ ~ which is elicited by the incomplete preference relation [less than or equal to] in [OMEGA] is a partial order.
The goal of the paper is improvement of the method of solving the problem of multicriteria synthesis of robust control multimass electromechanical systems by constructing a Pareto-optimal solutions, and taking into account the binary preference relations of local optimization criteria using multiswarm stochastic multiagent optimization of particle swarm, which reduces the time of determining the parameters of robust controllers multimass electromechanical systems and meet the diverse requirements that apply to the such systems operation in different modes.
