Relationship between vector variational-like inequality and optimization problems

Article Abstract:

In the article the relationships between vector variational-like inequality and optimization problems are established. It will help to identify the vector critical points, the weakly efficient points and the solutions of the weal vector variational-like inequality problem, under conditions of pseudo invexity.

A note on the subjective and objective integrated approach to determine attribute weights

Article Abstract:

The objective weight introduced by Ma et al. [Eur. J. Oper. Res. 112(1999) 397] can be very different from the objective weight obtained by the entropy method. The motive and rationale of the objective weight of Ma et al. are also analyzed.
