nowadays, project selection is a vital decision in many organizations. because competition among research projects in order to gain more budgets and to attain new scientific domain has increased. due to multiple objectives and budgeting restrictions for academic research projects have led to the use of expert system for decision making by academic and research centers. the existing methods suff...

In this contribution connections between input fuzzy relations R1, . . . ,Rn on a set X and the output fuzzy relationRF = F(R1, . . . ,Rn) are studied. F is a function of the form F : [0, 1]n → [0, 1] and RF is called an aggregated fuzzyrelation. In the literature the problem of preservation, by a function F, diverse types of properties of fuzzy relationsR1, . . . ,Rn is examined. Here, it is c...

we analyze a sequential decision making process, in which at each stepthe decision is made in two stages. in the rst stage a partially optimalaction is chosen, which allows the decision maker to learn how to improveit under the new environment. we show how inertia (cost of changing)may lead the process to converge to a routine where no further changesare made. we illustrate our scheme with som...

this paper proposes a method for ranking decision making units (dmus) using some of the multiple criteria decision making / multiple attribute decision making          (mcdm /madm) techniques, namely, interval analytic hierarchy process (iahp)          and the technique for order preference by similarity to an ideal solution (topsis).          since the efficiency score of unity is assigned to ...

researchers in their reviewing of international market literature which practical experiences in iran indicate it demonstrate that to choose a foreign market there are two approaches: expansion and systematic approach. firms that use expansion approach, through the culturally and geographically similar markets starts working in international markets. however, in systematic approach, firms use a...
