Content available Bidding languages for auctions of divisible goods
EN
Bidding languages are well-defined for combinatorial auctions. However, the auctions of divisible goods are quite common in practice. In contrast to combinatorial auctions, the feasible volumes of the offers are continuous in the case of divisible commodities. Such auctions are called continuous auctions. In the paper we introduce three families of bidding languages for continuous auctions. They are based on the concepts derived from the combinatorial auctions. We generalize the language families based on goods, bids, and some mixture of both of them, to the continuous case. We also analyze fundamental properties of the new languages. Simple examples, reflecting the complementarity and substitutability, are provided with exemplary representations in different languages.

Content available Designing Auctions: A Historical Perspective
EN
Auction is a form of organization of competition that leads to the assignment and valuation of resources based on the information obtained from the competing agents. From the perspective of systems science it is a distributed resource allocation algorithm applied in the environment with information asymmetry, i.e., where the interconnected and interacting subsystems have different information about the system as a whole. This paper presents an overview of the historical development of mathematical theory underlying modern approach to auction design. Selected practical applications of the theory are also discussed.

The platform for research on auction mechanisms is a distributed simulation framework providing means to carry out research on resource allocation efficiency mechanisms and user strategies. Both kinds of algorithms examined are completely user-defined. Interaction of algorithms is recorded and pre-defined measures for the final resource allocation are calculated. Underlying database design provides for efficient results lookup and comparison across different experiments, thus enabling research groupwork. A recognised, open and flexible information model is employed for experiment descriptions.

W pracy przedstawiona jest koncepcja wieloagentowego system opartego na architekturze SOA, który został zastosowany do zarządzania procesem złożonej akcji ratowniczej, w trakcie której wykorzystywane są zasoby oferowane przez służby publiczne różnych typów. Do celu przeprowadzenia efektywnego procesu decyzyjnego dotyczącego przydziału zasobów związanych ze świadczoną usługą zostały wykorzystane różne rodzaje aukcji.

In this paper the concept of a multi-agent system based on SOA is presented. It was applied to the management of complex rescue actions, during which the resources offered by public services of different types are used. For the sake of an efficient decision process performance related to resources connected with the services required, various types of auctions were used.

The article presents a method of analysis of market-based models for resource allocation in communication networks. It consists of several stages: classification of a market model, generation of input data, data adaptation to a tested model, test calculations and, finally, presentation and interpretation of results. A set of general criteria to assess various models has been proposed. Tests are run using dedicated computer applications, data is stored in open XML-based format originated in the multicommodity market model. Network topologies are derived from the SNDlib library.

In this paper we present a multicommodity bandwidth exchange model for balancing aggregated communication bandwidth resources (BACBR) that allows us to aggregate similar offers. In this model offers submitted to sell (or buy) the same, similar, or equivalent network resources (or demands for end-to-end connections) are aggregated into single commodities. BACBR model is based on the balancing communication bandwidth trade (BCBT) model. It requires much less variables and constraints then original BCBT, however the outcomes need to be disaggregated. The general model for disaggregation is also given in the paper.

W celu utrzymania poziomu emisji na najniższym poziomie istnieje potrzeba wprowadzania bardziej wyrafinowanych instrumentów finansowych. Amerykańska Agencja Ochrony Środowiska (EPA) wprowadziła system zbywalnych zezwoleń na emisję SO2, substancji będącej przyczyną powstawania kwaśnych deszczy. We wprowadzonym systemie, opalanym węglem elektrowniom przyznaje się zbywalne zezwolenia na emisję, na podstawie dotychczasowego zużycia paliw stałych.

To maintain the total emissions cap of SO2 on the lowest level we need to introduce a new and more sofisticated financial vehicles. United States Environmental Protection Agency's Acid Rain Program introduces such an innovative, market-based allowances trading system to reduce sulfur dioxide (SO2) emissions, one of the primary precursors of acid rain. Under this system, fossil fuel-fired power plants, are alloted tradable allowances based on their past fuel usage and statutory emission limitations.

Zbywalne zezwolenia na emisję stały się w ostatnich czasach bardzo popularne wśród twórców polityki środowiskowej. Sam pomysł wykorzystania tego instrumentu finansowego oparty jest na zasadzie przepływu praw do emisji ze źródeł o niskiej emisji do tych, których poziom emitowanych zanieczyszczeń jest wyższy. Istnieje przekonanie, że ta metoda pozwoli utrzymać kontrolę zanieczyszczeń na niższym poziomie kosztów niż byłoby to na podstawie systemu norm emisji (podatki od emisji).

Transferable discharge allowances have become new financial instruments very popular among environmental policymakers in recent years. The idea of this approachies based on the transfer of emission rights from sources with low control costs to those with high costs. Some believe that this approach could give us pollution control at a substntially lower cost than system based on effluent standard and would be more acceptable than emission taxes.
