Computational model of collective intelligence for meta-level analysis and prediction of free or quasi-free market economy
(2012) Szuba, Tadeusz; Szydło, Stanisław; Skrzyński, Paweł
This paper encourages the use of a computational model of Collective Intelligence as a major (meta-level) tool to analyze and predict behavior of socio-economical systems like free (or quasi-free) markets are. Researchers are aware, that economics is a study of human behavior, but lack of a proper formal tool has shifted research in economics into the language of money, production, consumption, etc. From an economic point of view, when analyzing free (quasi-free) markets, more important is group behavior than individual behavior because they result in changes of market indexes. Group behavior leads in specific cases to the emergence of »group intelligence« with the most famous case named »A. Smith invisible hand of market«. A computational model of Collective Intelligence allows for the formal extraction of the »system of inference processes« which run in an unconscious way in socio-economic structures. The construction of a proper formal and simulation model of such Collective Intelligence inferences allows us to take an attempt to predict outcomes in terms of economical results. The paper will present a formal basis, methodology of constructing Collective Intelligence systems for given socio-economic structures.

Koncepcja i realizacja molekularnego modelu obliczeń w analizie paradygmatu niewidzialnej ręki rynku Adama Smitha
(Wydawnictwa AGH, 2009) Skrzyński, Paweł; Szuba, Tadeusz
Invisible hand process which is widely believed to be present in free market is perceived as the process in which the outcome to be explained is produced in a decentralized way, with no explicit agreements between the acting agents. The second essential property is that the process is not intentional, however it' impact on the market is very strong. Such process might be described using collective intelligence computational model [2]. The paper describes the concept of market simulator which derives from microeconomic theory of utility and is based on collective intelligence computational model and the transformation of such model into a molecular model in which information is carried by information molecules among which reasoning processes might occur which lead to creation of new molecules carrying conclusions of such processes. Research made in this area proved [4] that such model is efficient and moreover has natural computation parallelism. Usage of such model might add extra value to the analysis of the nature of economic processes including invisible hand process. Initial experiments made by authors were aimed in investigation relation between real sphere and financial sphere in economic system - it is widely known that one of the main roles of the financial sphere is stimulation production in real sphere.

Próba wyjaśnienia paradygmatu »niewidzialnej ręki rynku Adama Smitha« w oparciu o model obliczeniowy kolektywnej inteligencji
(Wydawnictwa AGH, 2008) Szuba, Tadeusz; Skrzyński, Paweł
W ujęciu współczesnym »niewidzialna ręka rynku« to metaproces, którego rezultaty osiągane są w sposób zdecentralizowany, bez jawnych uzgodnień pomiędzy jego uczestnikami. Ponadto proces ten jest niezamierzony, a cele do jakich dążą pojedynczy uczestnicy rynku, nie są ani bezpośrednio zsynchronizowane, ani identyczne z wynikami tego procesu - wynik ten jest osiągany niejako »przy okazji«. Niemniej proces taki silnie oddziałuje na rynek w sensie regulacyjnym. Uczestniczący w nim agenci mogą być tego nieświadomi - dlatego proces taki nazywany jest »niewidzialnym«. Proces taki jest widoczny, gdy rynek analizowany jest z wyższego poziomu. To zjawisko ekonomiczne zadziwiająco pasuje do modelu obliczeniowego kolektywnej inteligencji. Autorzy przedstawiają koncepcję systemu symulacyjnego, który w zamierzeniu ma pozwolić na takie zamodelowanie rynku, aby taki proces zaczął zachodzić i tym samym umożliwić autorom analizę jakościową i ilościową fenomenu »niewidzialnej ręki rynku Adama Smitha« (NRRAS).

Rekultywacja i rewitalizacja kopalń węgla brunatnego na przykładzie Kopalni »Bełchatów«
(Wydawnictwa AGH, 2009) Kasztelewicz, Zbigniew; Kaczorowski, Jacek
The examples of lignite mine revitalization which were conducted in Poland and abroad were presented in the article. The attention was paid to the difficulties of lignite mine reclamation and possibility of their attractive regeneration. Mine closure and its reclamation are presently the Bełchatów Lignite Mine challenges. Nevertheless, this process will take a few dozen years, the vision of final revitalization should already be created. It ensures proper process of closing down and reclamation of the post-mining region course. Concept for Bełchatów Lignite Mine closure and revitalization, which was worked out by AGH University of Science and Technology staff, was presented in this article.

Simulation model for lignite handling at the Boxberg stockyard
(Wydawnictwa AGH, 2009) Kahnt, René; Sontag, Volker; Bauch, Thomas
The new-built unit R of the Boxberg power plant and the re-commissioning of the Reichwalde opencast mine in 2010 require the extension of the coal stockyard at Boxberg (KLP Bx), to meet the considerably higher coal handling requirements. Therefore, the plant-technical concept of the KLP Bx was extended. Aim was to proof the viability of the selected plant concept for a safe operational management, i.e. coverage of the coal handling via the coal stockyard within one reference week under consideration of the various technical and technological conditions under the given marginal conditions. A conventional verification was not possible due to the high variability of the whole system. In cooperation with GMB Senftenberg and G.E.O.S. Freiberg, a coal handling model was developed taking into consideration prioritized criteria for meeting the objective and marginal conditions. Based on the simulation tool GoldSim/RM further considerations of variants are enabled. An outlook for further fields of application was presented and the limitations were explained.
