Temperature fields in electric energy generators may lead to mechanical dissbalance of an already balanced rotor. The author collected information in a number of steam power plants and confirmed the existence of the problem. This paper presents the specific case of thermal deformation of the rotor, caused by an asymmetrical temperature field in scale of rotor. On the grounds of the relevant physical aspects, we proposed a mathematical model identifying fields in a turbo generator rotor and suggest the optimum control by which the unwanted effects are eliminated.

Market uncertainty and financial instability in the era of global competition force companies to work faster and increase productivity and business efficiency with continuous cost reduction and qualitative efficiency, which serves as a basis for strengthening the competitiveness and sustainable development of all, including SMEs -small and medium-sized enterprises of the textile and clothing industry. Various innovative contents and adequate technological solutions, as well as reengineering of business/production processes, with massive and adequate implementation of technical-technological innovations based on information and communication technologies -ICT and flexible automation, i.e. on the direct and efficient implementation sector defined information systems, also represent possible elements of functional competitiveness and sustainable development. Otherwise, changes in the environment and ways of doing business of companies require a better understanding and integration of data, as well as their more efficient exploitation in the functioning and development of the company, which imposes the need for permanent generation, adaptation and development of quality and efficient information systems. As a result of such requirements, the responses of industrial production through the implementation of technical-technological innovations are inevitable, whereby quality and efficient ICT infrastructure, coherence of innovative technologies and flexible production, as well as compatibility and complementarity of production and business information systems, are necessary elements and indicators of efficiency and quality. The implementation, efficient exploitation, as well as the development of various business and production information systems, obviously has its benefits, presented through more efficient, better quality and faster operations, but also disadvantages, because it is obviously conditioned by the stochastic laws of the global market, the variable human factor or the lack of high-quality, highly educated professionals staff, requirements for high initial investments, but also the specifics of the textile/clothing industry and SMEs, as well as the incompatibility of the implemented production and business systems.

Jedan od ključnih faktora u optimizaciji poslovanja preduzeća je upravljanje poslovnim procesima (BPM), disciplina koja kombinuje znanje iz oblasti informacionih tehnologija (IT) i nauke o upravljanju, i primenjuje ih na operativne poslovne procese, bilo da omogućuje praćenje i izvršavanje procesa ili upravljanje kroz procese dizajna, modelovanja, simulacije i analize, ili reinženjeringa ili optimizacije. Modelovanje je istraživački metodološki postupak pomoću kojeg se mogu generisati modeli koji mogu zameniti stvarnu pojavu, a podrazumeva dizajniranje procesa uz uključivanje svih troškova, resursa ili ograničenja, sa ciljem utvrđivanja funkcionisanja procesa pod različitim okolnostima. Često se modelovanje tretira kao jedini put do kreiranja "perfektnog" procesa, pa se tako i upravjanje poslovnim procesima vrlo često tretira kao modelovanje poslovnih procesa. Posle implementacije posebnih metodoloških postupaka u fazi prikupljanja i sistematizovanja podataka za formiranje modela, rad prezentuje načine participiranja, eksploatisanja i benefi te kompjuterskog modelovanja, kao fi nalne faze generisanja novih, optimizovanih i efi kasnih modela MSP. Preciznije, radi se o aktivnostima generisanja novog modela MSP za proizvodnju odeće, kroz reinženjering proizvodnog procesa poboljšanjem performansi, odnosno kroz optimizaciju proizvodnje fl eksibilnom i faznom implementacijom CAD/CAM sistema. Mora se napomenuti da se model bazira na podacima prezentovanim u prvom delu rada (brainstorming i Ishikawa), kao i na podacima baznih istraživanja rada i poslovanja MSP (anketa, SWOT i PEST analiza). Kljične reči: modelovanje, upravljanje poslovnim procesima, mala i srednja preduzeća.

This paper presents the basic ideas for programming the maintenance of complex technical systems, which is a set of rules for determining the diagnostic mode of the constituent parts of the system in the actual exploitation process and decision making regarding the need for their replacement or on the extent of the necessary maintenance based on the information of the actual technical condition of the system. Assuming that the condition based maintenance is, in fact, the management system of the technical state of the system in the exploitation process, upon choosing the strategy for the condition based maintenance we have performed an analysis of the applicability of formed variants of the maintenance programme and evaluated their efficiency by comparing them with basic indicators (for corrective and preventive maintenance). We have pointed out the importance of using the described maintenance programme to increase reliability level and decrease the stagnation of technical systems, which results in high efficiency, and thus increases the productivity of companies where the systems have been installed.
