SOLUTION OF A MULTI-CRITERIA DECISION- MAKING PROBLEM ON BASE OF PROMETHEE METHOD

Multi criteria decision making problem was considered. Review of existing multi criteria decision making methods was presented. Methods of solving this problem can be divided into two large groups: methods using the aggregation of all alternatives according to all criteria and the solution of the obtained one-criterion problem, the second group is associated with the procedure of pairwise comparisons. Promethee method have been considered with details. This method is based on the pairwise comparison of alternatives and specific aggregation procedures. The preference function are considered for minimization and maximization cases. As practice problem the job selection is considered. Three important criteria are used: salary, time, risk. The results of all computations are presented.

Stability and Bifurcation of a Delayed Time-Fractional Order Business Cycle Model with a General Liquidity Preference Function and Investment Function

In this paper, the business cycle (BC) is described by a delayed time-fractional-order model (DTFOM) with a general liquidity preference function and an investment function. Firstly, the existence and uniqueness of the DTFOM solution are proven. Then, some conditions are presented to guarantee that the positive equilibrium point of DTFOM is locally stable. In addition, Hopf bifurcation is obtained by a new method, where the time delay is regarded as the bifurcation parameter. Finally, a numerical example of DTFOM is given to verify the effectiveness of the proposed model and methods.

Method of Selecting a Radar Sample Preferably

A new method of selecting a radar sample preferably has been developed. The methods is based on the representation in the form of an additive function of the estimated functional of each normalized indicator characterizing the radar. For each variant of the compared samples, which makes it possible to evaluate the effectiveness of the radar with the help of a single integral indicator, and also to eliminate the uncertainty in the choice of the radar by taking into account additional indicators and to take into account the cost radar to the maximum of the preference function

The Preference Function of Stakeholders and Marketing Strategies for Banks in Tunisia

During recent years, due to the necessary fluctuations that have impacted the financial capitalism, value creation has emerged and found a good basis especially for the company’s shareholders as well as customers, suppliers, bankers, unions and of course the government. So, the birth of the notion of stakeholders is a strict notion, this theory applies to the entire economy. Moreover, the strategic choices are an important part of the banks; hence the importance of the choice of strategy becomes paramount to deal with developments in a rapidly changing environment. An effective bank marketing strategy keeps customers educated. This paper shows recommendations as to the measures to be adopted in order to improve the marketing effectiveness of the banks. The aim of this article is to show the importance of the preference function in banking strategic choices in Tunisia.

Optimal Licensing Contract: The Implications of Preference Function

Our analysis provides a rationale for the existence of a positive fixed-fee and output royalty in the licensing contracts. In this article, we show that the preference functions play an important role in this respect. As the market expansion effect gets weaker, it reduces the possibility of a royalty-only contract, thus increasing the possibility of the co-existence of a positive fixed-fee and output royalty in the licensing contract. Our argument is different from the existing reasons based on imitation, number of firms, product differentiation and decreasing returns to scale. JEL: D21, D43, L13

On the architecture of mate choice decisions: preference functions and choosiness are distinct traits

Mate choice is an important cause of sexual selection; it can drive the evolution of extravagant ornaments and displays, and promote speciation through the reproductive isolation generated by rapid divergence of sexual traits. Understanding mate choice requires knowledge of the traits involved in generating mate-choice decisions, and how those traits may interact with each other. It has been proposed that mate-choice decisions are the outcome of two components that vary independently: the preference function (the ranking of the attractiveness of prospective mates) and choosiness (the effort invested in mate assessment). Here we test this hypothesis by examining individual variation in female preference functions and choosiness in green treefrogs ( Hyla cinerea ). We show that measures describing preference functions and choosiness are not correlated. We also show that both components are influenced differently by variation in female body size, and that preference function shape (closed and preferring intermediate values or open-ended and preferring extremes) has a strong influence on this relationship: function traits are positively correlated with body size only for individuals with closed functions, while choosiness is positively correlated with body size for individuals with open functions, but negatively for those with closed functions.
