The main body of the paper is devoting to reporting an investigation designed to solve selected problems of production programming with a help of a computer simulation. The Ek_An_ – computer experimental environment with a DEF company simulation model incorporated was used as a main...

In the paper, we present some applications of Huff’s and Laksmanan–Hansen’s models to the trade area range analysis. The subjects discussed are illustrated by an example of the real area with three hypothetical trade centers. In order to quantitatively express the factors describing trade...

The paper shows the chosen elements of stochastic dominance and probabilistic dominance theory, as well as their utilization in multicriteria decision support problems. First part of this work contains the definitions of stochastic dominations. Second part contains the most essential part of the...

The main aim of this paper is to explore the information content of dividend and buy back announcements. Using daily data from the Warsaw Stock Exchange, we investigate the reaction of stock prices of the announcing firms as well as the industry rivals to the announcement issue. The regression...

In the paper a dynamic, interactive approach to the control of the project realization time is proposed. The duration time of the project activities is assumed to depend on certain factors, whose influence may change in time. On the basis of the project history up to a certain moment, the change...

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,...

Numerous problems that emerge in the process of project management can be presented as multi-criteria issues and solved with the help of the appropriate methods. The contracting authority, selecting one tender out of many available tenders, assesses them, taking into account various criteria,...

The Equalization method for the Stochastic Generalized Transportation Problem is presented. The algorithm allows to find the optimal solution to the problem of minimizing the expected total cost in the Generalized Transportation Problem with random demand. It is shown that the method is...

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...

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...
