Annual report 2011 49system with reliability enhancement by means of standard operatingsystem and the implementation of secure access control to grid resourcesby means of certificates. The last solved field in distributedenvironment is modular method for permanent or intermittent fault diagnostics.The diagnostic method is based on the knowledge of algebraicPetri net model of system, whereas the model is extended toprobabilistic and time parameters. The mobile computer network ispresented by wireless mobile ad hoc network. The project solves theproblem of node failure, packets losses and end-to-end communicationinterruption from the point of communication reliability.Study of emergence of strategies by neural networks (VEGA 1/0141/10)Project leader: J. PospíchalMembers UAPI: V. Kvasnička, P. Trebatický, Ľ. Varga, M. Kobza, J. PálfySupported by: Scientific Grant Agency of the Ministry of Education of Slovak Republicand the Slovak Academy of SciencesDuration: January 2010 – December 2011Description: The project from the area of distributed artificial intelligence willstudy emergence of strategies of multiagent systems, where singleagents have their cognitive organ implemented by a neural network.Agents, placed in a given environment, must adapt to carry out prescribedactivities (avoidance of obstacles, games, cooperation, ethnicconflicts, communication, and emergence of social structures). Neuralnetwork will be taught by reinforcement (reward/punishment) method.Activity of agents will be evaluated only after a longer time delay,when an external evaluator will be able to classify their behaviour assuccessful or unsuccessful. The proposed method will allow a systematicchange of weight coefficients of neural networks in such a waythat the successfulness of their activities will progressively grow.Robust MPC for Hybrid Systems (RPHS) (VEGA 1/1105/11)Project leader: Š. KozákMembers UAPI: M. Čerňanský, M. Makýš, J. ŠtevekSupported by: Scientific Grant Agency of the Ministry of Education of Slovak Republicand the Slovak Academy of SciencesDuration: January 2011 – December 2013Description: The last five years are marked by an increased interest in developmentof new control methods for heterogeneous hybrid process that includecontinuous and discrete dynamics. Research in control methods forhybrid non linear dynamic systems represent a new evolution trend indevelopment and application of control algorithms that help considerablyimprove performance of complex technological processes withina wide spectrum of applications (power industry, car industry, healthcare, biotechnologies, transportation, service industry). Those advancedmethods apply principles and methods of prediction, robustness,optimality and embeddedness. The main objective of the projectis research and development, algorithmization and implementation ofrobust predictive control methods for non linear hybrid processes us-
