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

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.

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

Walory systemu operacyjnego QNX i jego systemów sieciowych w rozproszonych instalacjach obiektowych systemu DCS MASTER

The paper presents the most important properties of the QNX system used in servicing the Distributed Control System (DCS) MASTER. Operating systems with a monolithic structure and microkernel systems are distinguished. The QNX system is a microkernel system. The QNX microkernel supports its system processes, as well as the DCS MASTER processes, with the ability to manage their execution on its own. In addition, various file systems are presented, including the power failure-proof QNX6 file system and reliable communication systems, both corporate and universal, based on QNET, TCP/IP and UDP/IP protocols. These systems enable access to distributed disk resources of the MASTER system stations and controllers. They provide tools to support large-size graphic displays and to implement local and remote diagnostic and servicing operations.W artykule przedstawiono najważniejsze właściwości systemu QNX, wykorzystywane w obsłudze systemu automatyki DCS MASTER. Wyróżniono systemy operacyjne o monolitycznej strukturze oraz systemy z mikrojądrem. System QNX należy do systemów z mikrojądrem. Mikrojądro QNX obsługuje swoje procesy systemowe, jak również procesy systemu DCS MASTER, z możliwością własnego zarządzania ich wykonywaniem. Przedstawiono ponadto różne systemy obsługi plików, w tym odporny na awarie zasilania system plików QNX6 oraz niezawodne systemy komunikacyjne, firmowe i uniwersalne, oparte na protokołach QNET, TCP/IP i UDP/IP. Systemy te umożliwiają dostęp do rozproszonych zasobów dyskowych stacji i sterowników systemu MASTER. Dostarczają narzędzi do obsługi wielkogabarytowych wyświetlaczy graficznych oraz realizacji lokalnych i zdalnych działań diagnostyczno-serwisowych

Exemplary industrial system and network modeling in Poland

The paper presents the exemplary industrial system models from the event-driven simulator up to Approximate network analytical performance evaluation system tool (Anapest). The basic approximations assumed in Anapest are roughly discussed together with the basic network configuration for which the tool was developed. The two basic ways of Anapest validation, i.e. the internal network measuring tool Sitwa and event-driven simulation are depicted. In addition, the major network performance evaluation projects run till now described, together with the basic outcome from Anapest
