Sumber daya manusia merupakan salah satu faktor penting dalam kemajuan sebuah perusahaan. Penilaian prestasi karyawan dilakukan untuk memacu kinerja agar menghasilkan yang berkualitas dan berdedikasi tinggi. Dalam pengambilan keputusan masalah sering terjadi terutama menentukan karyawan, maka di perlukannya Sistem Pendukung Keputusan dapat mencari alternatif terbaik berdasarkan kriteria-kriteri...

The concentration of livestock production is problematic due to environmental concerns. European regulations are guiding the sector become increasingly sustainable and, at same time, maintaining population in rural areas. aim was determine suitable areas municipalities where presented as a market option. methodology applied based on combination multi-criteria methods and geographic information ...

For most decision making problems, finding representative parameters of a decision maker’s preferences remains a challenging task. We here adapt to the Promethee II outranking method an eliciting procedure named Q-Eval that has been developed in the context of multi-attribute utility. It refines the estimation of the preference parameters by iteratively querying the DM through pairwise action c...

The classification problem statement of multicriteria decision analysis (MCDA) is to model the classification of the alternatives/actions according to the decision maker’s preferences. These models are based on outranking relations, utility functions or (linear) discriminant functions. Model parameters can be given explicitly or learnt from a preclassified set of alternatives/actions. In this p...

Ranking and selecting projects is a relatively common, yet often difficult task. It is complicated because there is usually more than one dimension for measuring the impact of each project and more than one decision maker. This paper considers a real application of project selection for ECNZ, Northern Generation, using an approach called ELECTRE. The ELECTRE method has several unique features n...

for $a,bin m_{nm},$ we say that $a$ is left matrix majorized (resp. left matrix submajorized) by $b$ and write $aprec_{ell}b$ (resp. $aprec_{ell s}b$), if $a=rb$ for some $ntimes n$ row stochastic (resp. row substochastic) matrix $r.$ moreover, we define the relation $sim_{ell s} $ on $m_{nm}$ as follows: $asim_{ell s} b$ if $aprec_{ell s} bprec_{ell s} a.$ this paper characterizes all linear p...

for vectors x, y ∈ rn, it is said that x is left matrix majorizedby y if for some row stochastic matrix r; x = ry. the relationx ∼` y, is defined as follows: x ∼` y if and only if x is leftmatrix majorized by y and y is left matrix majorized by x. alinear operator t : rp → rn is said to be a linear preserver ofa given relation ≺ if x ≺ y on rp implies that t x ≺ ty onrn. the linear preservers o...

in this article, we characterize the involutiveness of the linear combination of the forma1a1 +a2a2 when a1, a2 are nonzero complex numbers, a1 is a quadratic or tripotent matrix,and a2 is arbitrary, under certain properties imposed on a1 and a2.

in this paper, at rst for a given set of real or complex numbers  with nonnegative summation, we introduce some special conditions that with them there is no nonnegative tridiagonal matrix in which  is its spectrum. in continue we present some conditions for existence such nonnegative tridiagonal matrices.

ELECTRE TRI-nB is a method designed to sort alternatives evaluated on several attributes into ordered categories. It an extension of TRI-B that uses limiting profiles, instead one, delimit each category. In previous paper we have characterized the partitions can be obtained with TRI-nB, using simple axiom called linearity. The simplicity this characterization crucially rests possibility use as ...
