Opis:
People often fall into a state of waver. A smoker knows ”in the head” that smoking harms his health, but fells a desire to smoke in order to compose himself ”at heart”. In case of an ”observation” (say: illness), a waver gradually sets on – whether to smoke or not. This process can be described as having two states of nature (”in the head” and ”at heart”), one of which is hidden, and only gradually comes to the surface, which leads to an apparent conflict. In this paper, we propose a model for this situation and the respective decision making and a way to solve the resulting problem, using the precepts of the fuzzy set theory.

Opis:
The aim of this analysis is to draw conclusions from the consideration of the transformation of Polish economy from a command to a market driven one on the basis of results from innovation theory. As the starting point it is assumed that welfare is related to market economy with a considerable number of private and privatised companies. It will be further explained that these companies have to be innovative so as to be successful. The most visible innovation is related to the introduction of marketing units in companies. This, however, implies coping with two generic types of marketing conflicts. The first one is the structural marketing conflict: it results from the internal conflicting objectives. The second one is the marketing implementation problem: it results from the resistance attitudes. The model describing structural conflicts is presented in the paper. It is explained hope the model allows the use of existing computer software to support managers.

Opis:
We often fall into silence. After that, we make a decision through confusion, in most cases. In silence, cool mind runs parallel with warm heart. Traversing over these two, the phenomenon arises, chich can be interpreted as a fuzzy event, which can be called waver. In other words, two states of nature develop into conflict, and are covered by a fuzzy event. In confusion, we consider that the states of nature, which had been moving in conflict, not only undergo an inversion, but also a transformation takes place from warm heart into dry mind. It is therefore possible to derive a fuzzy function, resulting from the fuzzification of the transition matrix from silence to confusion, absorbing noise, and taking expectation to link the membership function with the multi-attribute utility function. This short note shows that we can calculate the expected utility by using both the probability of a fuzzy. event and the subjective importance of the two states of nature for the decision maker. Further, we can obtain an optimum action, based on the theory of maximum expected utility.

Opis:
We introduce a new aggregation operator that unifies the weighted average (WA) and the ordered weighted averaging (OWA) operator in a single formulation. We call it the ordered weighted averaging - weighted average (OWAWA) operator. This aggregation operator provides a more complete representation of the weighted average and the OWA operator because it considers the degree of importance that each concept has in the aggregation and includes them as particular cases of a more general context. We study different properties and families of the OWAWA operator. The applicability of this method is very broad because any study that uses the weighted average or the OWA can be revised and extender with our approach. We focus on a multi-person decision-making application in the selection of financial strategies.

Opis:
Developing an effective business strategy ought to be based on the aspects of rationality, not only with the roots of present time, but also with the past and characteristics acquired in previous competitive episodes that may form the context for future ones. Thus, in analyzing the possibility of supporting decisionmaking process, one should take into account the essential properties of economic entities (objects), such as their complexity, dynamics and nonlinearity. Within this perspective, in order to model the dynamic behavior, system dynamics approach has been used in the work here reported. This technique complements the popular management approach of balance scorecard, providing the multidimensional view of an enterprise and expressing the interrelations among different processes in it.

Opis:
The paper presents a decision-making model of environmental modernization in a power plant. The goal of the model is to analyse strategies implemented by power producers trying to comply with environmental regulations. Detailed analysis is related to the sulphur dioxide emission. Tradable emission allowances might be a new economic tool in fighting environmental problems in Poland. The model applies the real options approach. The approach is appropriate to model investments that are irreversible and an investor can afford to wait rather than invest immediately. The model assumes price uncertainty. The investment rule takes the form of a critical value optimal for immediate investment. The critical value of the project is calculated using dynamic programming. The project value follows a geometric Brownian motion. The results presented demonstrate that it is possible to calculate a critical price of emission allowances.

Opis:
A ranking approach based on grey correlative coefficient is presented to solve the multiple attribute decision making problems in which the attribute values and the weights take the form of the generalized interval-valued trapezoidal fuzzy number (GIYTFN). Firstly, the concept and the calculation rules of GIYTFN are introduced, the distance of GIYTFN is proposed. Secondly, the method of linguistic terms transformed into GIYTFN and the normalization method of GIYTFN is illustrated, and a grey relational decision making method based on the GIYTFN is presented in detail. The alternatives are ranked based on the grey correlative coefficient. Finally, an illustrative example is given to show the effectiveness of this method and the decision making steps.

Opis:
We propose a methodology to support decisions on how to construct rankings of objects which account for decision makers' preferences. As it is not always so that objects to be ranked are known upfront, the methodology is focused on constructing ranking algorithms rather than rankings themselves. The methodology builds on Multiple Criteria Decision Making paradigms. To operationalize it we provide a consistent interactive framework which allows the decision maker to express his preferences with respect to objects directly, with respect to the criteria selection process (multiple criteria model building), and with respect to attributes resulting from the selected criteria. The methodology is illustrated by a numerical example of municipality rankings.

Opis:
This research deals with a phenomenon well-known in socio-economic studies and referred to as the Agency Theory: the principal-agent problem. The agent is designated to act on behalf of the company owner, i.e., the principal, in the domain of supply chain management in the face of a supplier’s default uncertainty. Each of the players is gain-oriented, but their objective functions and the degree of risk-bearing may significantly differ, leading to an agent’s decisions not being optimal in terms of the principal’s outcome. This article proposes a multi-period supply chain simulation model that can be used to perform a supply chain optimization and comparison between the agent and the principal. The proposed framework allows for differentiating the model parametrization depending on the industry, in particular the consequences of the inability to deliver the end product, costs of keeping safety stocks, or the uncertainty regarding the suppliers’ delivery failure. As players’ objective functions, we consider expected profit-based indicators and measures taking the inter-period variance into account. We find that the agent’s actions may diverge from the principal’s optimum if the agent’s incentive system is not selected correctly. We also propose a solution that unifies the goals of the players. The recent COVID-19 pandemic amplifies the importance of such research. Many companies had to limit production capacities due to global lockdowns and, per the JIT production strategy, the prior safety stock levels were low.

Opis:
The paper considers major principles of methods based on quantitative measurements. The problem of construction investments is of paramount importance because they determine the potential of construction and the structure of expenses. The calculation of investments is an expensive tool of enterprise management used in planning the investments. It can be perceived as the harmonization and evaluation of the models for investment decision-making. Methods based on a single criterion can hardly be used in solving the problems associated with sophisticated technological or marketing systems. It is a multiple attribute decision method, taking into consideration major efficiency criteria, that enables the effective methods of solving complicated problems. When the quantitative criteria are precisely defined, the developed quantitative multiple criteria decision making (MCDM-1) method can be successfully applied. The present paper is devoted to the analysis of the algorithm and methods of application of the suggested technique.

Opis:
Deriving efficient variants in complex multiple criteria decision making problems requires optimization. This hampers greatly broad use of any multiple criteria decision making method. In multiple criteria decision making Pareto sets, i.e. sets of efficient vectors of criteria values corresponding to feasible decision alternatives, are of primal interest. Recently, methods have been proposed to calculate assessments for any implicit element of a Pareto set (i.e. element which has not been derived explicitly but has been designated in a form which allows its explicit derivation, if required) when a finite representation of the Pareto set is known. In that case calculating respective bounds involves only elementary operations on numbers and does not require optimization. In this paper the problem of approximating Pareto sets by finite representations which assure required tightness of bounds is considered for bicriteria decision making problems. Properties of a procedure to derive such representations and its numerical behavior are investigated.

Opis:
We propose an approach, which we believe, can be pivotal for wider applications of Multiple Criteria Decision Making methods in practical problems. The idea is to represent decisions by approximate rather than by exact values of criteria. By this it is possible to eliminate the need of solving optimization problems from decision making processes. This in turn has far reaching consequences for versatility of decision making methods when modified accordingly to absorb the proposed approach.
Zaproponowano podejście, o którym należy sądzić, że stanowi istotny postęp w dziedzinie szerszego zastosowania metod wielokryterialnego podejmowania decyzji do zagadnień praktycznych. Idea polega na przybliżonej raczej niż dokładnej reprezentacji decyzji przy pomocy wartości kryteriów. W ten sposób staje się możliwe wyeliminowanie potrzeby rozwiązywania zadań optymalizacyjnych z procesu podejmowania decyzji. To zaś ma daleko idące konsekwencje dla elastyczności metod podejmowania decyzji, zmodyfikowanych w celu uwzględnienia zaproponowanego podejścia.

Opis:
This paper presents a practical case involving a shopping mall location problem in the northeast countryside of Brazil. In this problem, conflicting objectives have been expressed in terms of seven criteria. Then, ten cities of the northeastern countryside have been selected to compose the space of actions. The problem plays a special role since Brazil is a big country that requires investments in the countryside. Thus, the shopping mall aims to stimulate economic growth in the respective region. In the study, this multi-objective problem is solved using the FITradeoff method. In FITradeoff, the combination of the paradigms of holistic evaluation and elicitation by decomposition in preference modeling are well explored, bringing different perspectives for the decision-maker during the decision process.

Opis:
In multicriteria problem solving, much can be learned by observing the decision-making process. Some, if not many, of the theoretical constructs used in some academically-generated models are simply not necessary. Taking this into account, we generalize the Zionts-Wallenius Multiple Criteria Decision Making Algorithm. We generalize the approach so that it can solve general convex problems. We do this by drawing from other methods, and by incorporating what we have learned in our work. To deal with the class of convex problems we face, we broaden the concept of tradeoff, and use global tradeoffs. Theory is developed, and then a method incorporating the theory is presented. A small example is included. We discuss how our development enriches decision-making tools currently available. We discuss applications in finance and technology.
