Two different approaches were implemented to aid the process of selecting the best variant of road construction, namely approach based on the outranking relation and verbal decision analysis. Out of wide range of outranking methods three very well known were applied: ELECTRE Iv, PROMETHEE I and PROMETHEE II. In the case of VDA UniComBOS was used. The results obtained with different methods were not identical, nevertheless it was possible to identify variant worth recommendation, i.e. variant 2 a , which was always on one of two first places in rankings, regardless of the method that was used. On the other hand, variant 5 a was found to be the worst solution - its weakness was confirmed by all methods. The analysis conducted in the article proved that both described approaches can be used for solving the decision-making problems connected with project management. Although both of them have some disadvantages, as for example necessity to interact with decision-maker in order to determine values of parameters in the case of outranking methods and time-consuming as well as tiring comparisons in the case of VDA, they can improve the decision-making processes and help project managers to make more reasonable decisions. As a matter of fact, because of the differences between them, they can complement each other. Therefore it would be practical and beneficial to employ them simultaneously in all cases when it is merely possible and feasible.

Theorems about the rational decision making play very important role in the decision theory. According to these theorems people make their decisions by using the rule about maximum benefits. However in the literature we can find conclusions from research and experiments which indicate that when people are making decisions, they are very often breaking that rule about maximum profits. According to that research a few paradoxes of rationality were formulated. In this article experiments concerning the Allais paradoxes are analyzed. The incompatibility between paradox and the expected utility theory were discussed. Also the certainty effect and the common consequence effect were analyzed.

In this paper an impact of the party’s negotiation profile on the misperception of the preferential information provided to the negotiating parties is studied. In particular, the problems with determining an adequate and preferentially correct negotiation offer scoring system is analyzed, when the parties are supported in their decision analyses by means of the SAW technique. In the analyses we use the negotiation data from bilateral negotiation experiments conducted by means of the Inspire negotiation support system. To determine the negotiators’ profiles the Thomas-Kilmann Conflict Mode Instrument was used, which allows to describe their general negotiation approach using two dimensions of assertiveness and cooperativeness. The accuracy of scoring systems was defined as the extent to which the negotiator’s individual scoring system (agent’s system) is concordant to the preferential information provided by the negotiator’s superior (principal’s system) in the form of verbal and graphical descriptions, and measured by means of ordinal and cardinal accuracy indexes.

Who, what, when, where, why, in what way, by what means? - These are "seven golden questions" which a police officer should ask themselves before they make a decision. The subject matter of the paper is description of the decision-making by police superiors. The results of research aimed at confirming the specificity of decision making in police and defining police officers' behavior in difficult and stress-inducing situations of any kind which they regularly encounter while performing official duties. The goal of the study is also to indicate that making managerial decisions combines rational analysis aspects with intuition. Being on duty superiors pay attention to information concerning safety aspects. This kind of information is vital in order to take the actions staying in compliance with applicable law and not posing a threat to them, inferiors and society.

Od kilku lat można zaobserwować dynamiczne zmiany natury regulacyjnej i technologicznej, które mają duży wpływ na marże i zyskowność w sektorze bankowości detalicznej. Przy pojawiającej się presji rynkowej na konsolidację w polskim sektorze bankowym, coraz większe znaczenie ma prawidłowa ocena projektów inwestycyjnych w kontekście ich wyceny. Jedną z metod wspomagających wycenę projektu jest podejście szacowania długookresowej wartości klienta – CLV (Customer Lifetime Value). W pracy przytoczono różne podejścia do szacowania CLV oraz opisano przykład szacowania wskaźnika na gruncie polskim.

For several years, there have been observed some dynamic changes of the regulatory and technological nature, that have a large impact on margins and profitability in retail banking. With emerging market pressure for consolidation in the Polish banking sector, it is increasingly important to properly assess the investment project in the context of their valuation. One of the methods supporting the valuation of the project is the CLV (Customer Lifetime Value) approach. The paper presents different approaches to estimating CLV and describes an estimation of the indicator in the Polish market.

The Hurwicz rule and the Bayes rule are classical approaches applied in the decision making under uncertainty. This situation occurs when the decision maker may choose one of several alternatives and he or she is only able to assign to each of them an interval of potential payoffs or a set of possible profits. In both cases the answer obtained depends on the state of nature (scenario) which will happen, but in the first case the set of scenarios is infinite and in the second one - it is finite. The Hurwicz measure, with the aid of the coefficient of pessimism and the coefficient of optimism, enables to find the optimal pure strategy when the decision selected is performed only once. Meanwhile the Bayes criterion is designed to indicate the optimal pure or mixed strategy when the variant chosen is performed once or many times. In the first part of the article the author analyzes the Hurwicz rule and illustrates cases when the use of this criterion leads to quite unexpected results which seem to be contradictory with the logic and do not reflect the decision maker's preferences. In the second part a proposal of an approach for optimal pure strategy searching (by means of formulas considering both the coefficients of pessimism and optimism, as well as the whole set of payoffs) is presented. This procedure (H+B rule) combines elements of the Hurwicz criterion and the Bayes criterion, but is deprived of disadvantages typical of the Hurwicz rule. The rule suggested takes into consideration both extreme payoffs and intermediate payoffs, which enables to receive rational recommendations for a larger spectrum of decision problems. The H+B rule may be applied in the decision making process under uncertainty when the number of potential scenarios and the set of possible payoffs are finite, however a slight modification of the equations proposed enables to use this procedure in problems with continuous payoffs.

Rezultaty wielu przedsięwzięć rozwojowych realizowanych jako projekty mogą zależeć od zmiennych czynników środowiskowych. Wpływają one na wartość tegoż projektu poprzez wykorzystanie pojawiających się możliwości, co jest możliwe tyko w warunkach właściwego zarządzania. Owe możliwości są nazywane opcjami realnymi. Do ich wykorzystania jest konieczne oszacowanie przyszłych zmian wartości tych czynników. W kontekście zrównoważonego rozwoju są to czynniki nie tylko ekonomiczne, ale także społeczne oraz związane ze środowiskiem naturalnym. Na podstawie obserwacji danych historycznych możliwe jest tworzenie scenariuszy przyszłych zachowań tych czynników. Takie scenariusze mogą przybierać formę drzew dwumianowych. Niniejszy artykuł przedstawia ocenę parametrów drzew dwumianowych dokonaną na podstawie obserwacji historycznych czynników środowiskowych mogących mieć wpływ na projekty zrównoważonego rozwoju regionów.

The results of a number of development projects may depend on the variable environmental factors. They may affect the value of that project, through the use of emerging opportunities, which is possible only in the conditions of proper management. These opportunities are called real options. To use them, it is necessary to estimate future changes in the value of these factors. In the context of sustainable development, the factors are not only economic but also social and related to environment. Based on the observation of historical data, it is possible to create scenario future behavior of these factors. Such scenarios may take the form of binomial trees. This paper presents the evaluation of the parameters of binomial trees made based on historical observations of environmental factors that may influence on the projects of sustainable development of regions.

The behavior of the risk averse decision-maker is prudent if the precautionary saving activities are taken to avoid risk. Prudence is defined as a particular type of the preference relation over uncertain choices. Our goal in this paper is to show the relationship between the Arrow-Pratt coefficient of the risk aversion and the measure of the intensity of prudence. The properties of the utility function expressing prudence behavior are presented and the particular class of utility functions with non monotonic absolute risk aversion coefficient is considered.

We present a new interactive procedure for multiobjective optimization problems (MOO), which involves robust ordinal regression in contraction of the preference cone in the objective space. The most preferred solution is achieved by means of a systematic dialogue with the decision maker (DM) during which (s)he species pairwise comparisons of some non-dominated solutions from a current sample. The origin of the cone is located at a reference point chosen by the DM. It is formed by all directions of isoquants of the achievement scalarizing functions compatible with the pairwise comparisons of non-dominated solutions provided by the DM. The compatibility is assured by robust ordinal regression, i.e. the DM's statements concerning strict or weak preference relations for pairs of compared solutions are represented by all compatible sets of weights of the achievement scalarizing function. In successive iterations, when new pairwise comparisons of solutions are provided, the cone is contracted and gradually focused on a subregion of the Pareto optimal set of greatest interest. The DM is allowed to change the reference point and the set of pairwise comparisons at any stage of the method. Such preference information does not need much cognitive e ort on the part of the DM. The phases of preference elicitation and cone contraction alternate until the DM nds at least one satisfactory solution, or there is no such solution for the current problem setting.

In this paper analytic hierarchy process (AHP), a well-known approach for handling multi-criteria decision making problems, is discussed. It is based on pairwise comparisons. The methods for deriving the priority vectors from comparison matrices are examined. The existing methods for aggregating the individual comparison matrices into a group comparison matrix are revised. A method for aggregation, called WGMDEA, is proposed for application in the case study. Because exact (crisp) values cannot always express the subjectivity and the lack of information on the part of a decision maker, the interval judgments are more suitable in such cases. Two main methodological problems emerge when dealing with interval comparison matrices in group AHP: a) to aggregate individual crisp preferences into the joint interval matrix, b) to calculate the weights from the joint interval comparison matrix. In the paper we first discuss the already proposed approaches to the aggregation of individual matrices, and the derivation of weights from interval comparison matrices, pertained to AHP group decision making methodology. Then, a new method, ADEXTREME, for generating the interval group judgments from individual judgments is proposed. A numerical example based on Rural Development Program of the Republic of Slovenia in 2007-2013 is presented to illustrate the new methodology for deriving the weights from interval comparison matrices. The results obtained by WGMDEA, MEDINT and ADEXTREME methods are compared.

An important part of the innovation management is to select the best new product project from the preliminary large set of potential alternatives. This problem is broadly discussed in the extant literature. Although the qualitative approaches dominate in literature, there are few examples of more formal decision procedures based on multiple criteria analysis. This article brings an example of interactive procedure that can help decision making in the new product development. As to the authors knowledge, such approach has not been proposed so far to the problem of selecting new product. The interactive procedure gives to the DM an opportunity to actively participate in the whole process and observe its development. During the procedure, the DM can disclose his preferences and values of trade-offs. This kind of assessment of differences in importance of criteria is assumed as more reliable then the direct assessment of weights.

This article presents a model of searching for some resource, e.g. a job, whose value depends on two quantitative traits. The decision maker observes offers in a random order and must accept precisely one offer. Recall of previously observed offers is not possible. It is assumed that the value of an offer is a linear function of these two traits, which come from a bivariate normal distribution. We consider the following four strategy sets: i) the decision on whether to accept an offer is based purely on the first trait, ii) any decision is only made after observing both traits, iii) after observing the first trait, the decision maker can either immediately accept, immediately reject or observe the second trait and then decide, iv) after observing the first trait, the decision maker can either immediately reject or observe the second trait and then decide. The goal of the decision maker is to maximize his expected reward, where the reward is equal to the value of the offer selected minus the search costs. The optimal strategy from each of these four sets is derived. An example is given.

The article presents an application of chosen multi-criteria decision making method - the AHP method, under conditions of linear par tial information, in portfolio selection. Selecting a portfolio is a problem of choosing these quoted companies that give good profit. The problem of building a portfolio can be treated as a multi-criteria problem where some diagnostic features that characterize financial and economic condition of companies can be used as criteria. In the paper, the multi-criteria decision making method AHP was used under conditions of linear partial information (the criteria weights are not known precisely, only some linear cons traints on them are known). The approach enables to create a ranking of considered objec ts and may help to select the best listed companies to the portfolio.

W artykule została zaproponowana nowa koncepcja modelowania działań podejmowania decyzji przez operatorów z użyciem analogii do teorii kontroli automatycznej. Autorzy potwierdzili hipotezę dotyczącą możliwości opisu specyfiki myślenia operatorów systemów kontroli automatycznej (zbiór warunków, metody i wyniki podejmowania decyzji) w nieprogramowych sytuacjach (ograniczenia, zagrożenia, swoboda działania) z dostateczną dokładnością z użyciem nieliniowych elementów. Zostało udowodnione, że główną cechą wyróżniającą Model Heurystyczny/ Intuicyjny w porównaniu do modelu Racjonalnego Podejmowania Decyzji jest obecność tak zwanego zjawiska "wzbogacenia" ("enrichment") informacji wejściowej o ludzkie preferencje, hobbies, tendencje, oczekiwania, aksjomaty, osądy, uprzedzenia i ich uzasadnienie. W artykule rozwinięto modele symulacji i taksonomię nieliniowych elementów (operatorów) zależnych od rodzaju modelu podejmowania decyzji. Został zaproponowany autorski, oryginalny rodzaj nieliniowego elementu, który rozszerza możliwości interpretacji i formalizacji jakościowych i ilościowych wymagań dla wzbogacenia umiejętności decydenta.

In the paper we propose a practical application of the path goal programming approach, by which we understand a goal programming approach with goals being not numbers, but paths in networks. This method, with goal paths corresponding to desired schedules of environmental investment implementation, is used for the environmental decision-making in a selected company. The company has to introduce some investments aimed at natural resources reduction. However, not all the required investments can be realized in one budgeting period, because of budget constraints. The desired compromise schedule of investment realization has to be worked out. This schedule becomes the goal. The path goal programming method helps to reduce the undesired deviations from the goal schedule.
