An iterative multicriteria closed-auction conducted with the use of a multi-agent computer-based system is analyzed. This system supports the submission of offers, multicriteria analysis carried out by the organizer of the auction, simulation, and analysis of the behavior of competing bidders. Analysis of incentive compatible decisions is the main subject of this research. A mathematical formulation of the decision making problem and selected results of a bidding session conducted using this system are presented and analyzed.

In connection with the ongoing process of liberalization in the Polish electricity market, customer orientation and its needs are becoming an important competitive advantage of electricity trading companies. The aim of this article is an attempt to present and solve the problem of fitting baseload and peakload futures contracts to future planned energy demand as a multicriteria programming problem. Due to the large number of variables and nonsmooth criteria the Monte Carlo simulation was used to solve the problem. The model has been built to minimize price and imbalance volume between future planned demand and standard products able to purchase on the Polish commodity market. Due to future SPOT, the settlement simulation model requires future SPOT prices.

Analizowane są skutki ograniczenia emisji CO2 dla rozwoju gospodarczego Polski. Narzędziem analizy jest model składający się z czterech sektorów produkujących odpowiednio: energię, nieenergetyczne nakłady pośrednie, dobra konsumpcyjne, dobra inwestycyjne, jak również z sektorów konsumpcji oraz wymiany z zagranicą. W każdym z sektorów rozpatrywane są różne technologie ze względu na ich efektywność ekonomiczną oraz emisyjność. Uwzględniono handel pozwoleniami i handel zagraniczny. Optymalizacja uwzględnia dwa sprzeczne cele: maksymalizację konsumpcji oraz minimalizację emisji CO2.

Paper presents the bicriteria analysis of the impact of the limits of the allowances for CO2 emissions on economic growth of Poland. The long-term model is presented, which consists of four production sectors, which produce: energy, intermediary goods, consumer goods and investment goods, respectively, as well as the consumption sector and the foreign trade sector. In each production sector different technologies are considered. Trade in goods and the emission allowances are accounted for. Contradictory goals are considered: the consumption maximization, and minimization of gaseous emissions.
