An increasing number of bankruptcy announcements causes that even greater attention is put to the correct evaluation of probability of default (PD) and decisions made on the basis of it. Reliable estimation of bankruptcy threat reduces the risk not only for the company itself but also for all...

When dealing with multi-criteria decision making problem the concept of Pareto -optimality and Pareto-dominance could be inefficient (the lack of unique solution), especially with many number of criteria. Our paper faces the fuzzy multi-criteria decision making problem based on Zadeh’s...

The reality of modern times places increasing emphasis on the use of research results. This paper presents programs which implement the tools for interactive methods of decision support under risk, proposed by M. Nowak, as a complementary way to disseminate research results. It also presents a...

There are commonly accepted and objective decision rules, which are consistent with rationality, for example the stochastic dominance rules. But, as can be seen in many research studies in behavioural economics, decision makers do not always act rationally. Relatively new tools which model real...

The paper presents six ways to move a warehouseman during order picking process. Ratliff and Rosenthal in 1983 developed an efficient algorithm for determining the optimal route. It’s use in practice, however, involves the need to implement the relevant computer system. It is not always...

This article presents a review of results of the author (Klukowski 2011a) in the area of estimation of the relations of: equivalence, tolerance and preference within a finite set, on the basis of multiple, independent (in a stochastic way) pairwise comparisons with random errors, in binary and...

In this paper a basic resource allocation problem with uncertain costs is discussed. The problem consists in choosing exactly p items out of n available to minimize the total cost. The uncertain item costs are specified as a discrete scenario set and the minmax criterion is used to choose a...

Scoring the negotiation template and building the scoring system of the negotiation offers is a starting point for negotiation analysis. It is usually done by means of classic additive scoring model. Latest research confirms however that TOPSIS may be a good alternative for SAW-based models,...

In the paper we model the problem of optimal assignment of respondents to internet questionnaires. The task is taken from a leading online survey company in Central and Eastern Europe which runs several dozen of surveys in parallel. Each survey has a unique respondent inclusion criteria based on...
