Network modeling technique: A case study

Dimirovski, Georgi M. (Dogus Author) -- Conference full title: 2010 7th International Symposium on Communication Systems, Networks and Digital Signal Processing, CSNDSP 2010; Newcastle upon Tyne; United Kingdom; 21 July 2010 through 23 July 2010From the very beginning of computer systems and networks, there has been a severe lack of analytical techniques enabling effective performance evaluation/prediction for actual systems and networks. Such techniques were needed, in particular, for the systems developed in rather poorly countries where the hardware available for the designers was obsolete in comparison to that available in well developed countries. The paper describes some experience in ICT system modeling and the network modeling tool and technique worked out.Northumbria University, Newcastle University, The Institute of Electrical and Electronics Engineers (IEEE), IEEE United Kingdom and Republic of Ireland (UK and RI) Section, IEEE UK and RI Communications Chapte

An approximate actual network performance evaluation method

Dimirovski, Georgi M. (Dogus Author) -- Conference full title: UKSim/AMSS 1st International Conference on Intelligent Systems, Modelling and Simulation, ISMS 2010; Liverpool; United Kingdom; 27 January 2010 through 29 January 2010Since early eighties, not too many happened in analytical methods of performance valuation for actual computer and communication networks. The methods of the classic queuing theory (the mean value analysis, the convolution method) adopt unrealistic assumptions. The stochastic queuing network methods are not adequate for investigation of actual networks. Therefore, the paper presents an approximate method based on many-year performance evaluation experience and some heuristics. The approach is based on the notion of the closed route within the computer network under investigation; the complete network being described as a collection of such closed routes. The method was successfully validated by simulation and measurements. Some more complex approximations, feasible due to development of the computing tools, are also proposed

Barriers to ethical behaviour: a case study of Poland

Dimirovski, Georgi M. (Dogus Author) -- Full conference title: 18th IFAC World Congress Milano (Italy) August 28 - September 2, 2011.Before the political change in the Case-study country of Poland, the system governing there encouraged unethical behaviour or even forced it. The paper discusses the most frequent methods used by the unethical power to force the actual pioneers of ICT and automation in the case study country to abandon performing their professions. The example of the most experienced leading designer of ICT and automation in the pioneering era in Poland depicts some effective ways to struggle with the improper actions of the power

Computer integrated manufacturing and management systems. An emerging application of control and management

An approach to factory automation is the basis for a case study of Computer Integrated Manufacturing and Management systems (CIMMs). The paper presents some experience in large-scale systems and the current state-of-the-art for the domain. A feasible approach is proposed, based on prospective user expectations and the system development with the use of so-called first thread for which the standards facilitating the development of subsequent systems should be developed, and people acquainted with both manufacturing and management problems should be educated. There is also depicted some research work intended for facilitating the design and implementation of future CIMMs
