Design and Development of Computer Integrated Manufacturing and Management Systems for Manufacturing Enterprises

An approach to design of a large-scale distributed system intended for factory automation is described for a case study of Computer Integrated Manufacturing and Management systems (CIMMs). Some aspects of the two basic approaches to design of CIMMs (by-organisation and by-thinking) are compared. The paper presents some experience in design and development large-scale systems and the current state of art for the domain. A feasible approach (by-thinking) is proposed for that distributed system, based on prospective user expectations and the system development with use of so called first thread on which the standards facilitating development of subsequent systems should be developed and people acquainted with both manufacturing and management problems should be educated. There is also depicted some modelling and analysis work intended for facilitating design and implementation of future CIMMs, being a good example of complex computer systems

Power Industry Computer Control System Design and Implementation Problems: A Case Study of Poland

The design and implementation team of computer automation systems for the Polish power industry faced many difficult problems connected with the lack of experience in this domain in the country. Another kind of problems was implied by different levels of information and communication technology in that country and in well developed ones. The differences were generated by both internal (importation limitations) and external (various embargos) reasons. But perhaps the most severe problems were the political ones, implied by the omnipotent communist system, that could spoil and often spoiled even many-year work of design and implementation teams. The paper tries to answer how, in such adverse conditions, it was possible to design and develop very successful power industry computer automation systems

Power generation/distribution control systems topology selection based on robustness evaluation

Dimirovski, Georgi M. (Dogus Author)The problem of the data acquisition/control system topology for distributed control systems in big power plants and/or power distribution centres is usually solved in a rather arbitrary way. The paper presents some reasonable approached based of evaluation of the system robustness, using the μ function as the measure or robustness. The paper proposes a method feasible for actual system designers since computational effort is rather low for communication systems described with time-delay members only

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

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
