<p>Cilj ovog istraživanja bio je da se razvije model za ocjenu<br />efikasnosti i efektivnosti željezničkih operatera koji bi<br />bio u funkciji povećanja konkurentskih sposobnosti istih. Da<br />bi se to ostvarilo na osnovu stanja u literaturi i praksi,<br />definisani su i vrednovani kriterijumi koji utiču na<br />efikasnost i efektivnost i izvršen njihov izbor primjenom<br />fazi AXP. Razvijeni su modeli za ocjenu efikasnosti<br />željezničkog operatera. U razvoju modela korišćeni su<br />principi DEA i fazi logike da se modeluje neodređenost u<br />podacima i koristi ekspertsko znanje za ocjenu. Testiranjem<br />modela na željezničkom operateru u BiH zaključeno je da je<br />model primjenljiv kao alat za ocjenu efikasnosti.</p> / <p>The objective of this study was to develop a model for evaluating the<br />effectiveness and efficiency of railway undertakings, which would be<br />aimed at increasing the competitive capabilities of the railway<br />undertakings. In order to achieve this on the basis of the state in<br />literature and practice, the criteria that affect the efficiency and<br />effectiveness are defined and evaluated and their selection is made<br />with the application of Fuzzy AHP. Models for the assessment of the<br />efficiency of railway undertakings have been developed. In developing<br />the model, the principles of DEA and Fuzzy logic have been used to<br />model the uncertainty in the data and to use the expertise for<br />assessment. By testing the model on the railway undertaking in Bosnia<br />and Herzegovina it was concluded that the model is useful as a tool for<br />the assessment of efficiency.</p>

This doctoral thesis deals with the aspects of evaluation of balance and optimality of corporate information systems. The initiative for this specialization was given by the increasing importance that is being laid on the perception of information systems from the point of view of a business company. More and more resources are being invested in the domain of information systems, but afterwards, it is not always ascertained that the information system is such a system, one could characterize as balanced and optimal for the company today as well as in the future. Often this is because there does not exist for the company an available and easily applicable methodic how to evaluate the system. As one of the main starting points of this doctoral thesis I have chosen the methodic HOS8 that was published 5 years ago on our faculty. The newly proposed methodic HOS2009 is trying to clear up the weak points of the original HOS8 methodic that were discovered during its practical use. This is done mainly by using the information feedback from the applicants of the methodic. Within the scope of this thesis the factors influencing the level of the particular areas of the system and the influence of these areas on its general balance are being examined. With regard to the evaluation of the balance and optimality of the information system, in this thesis the problematic of determination of a balanced and optimal state of information system for a company nowadays as well in the future are being examined. As a part of the methods output the thesis presents also charts representing the general state of the system, the imbalance of the particular parts of the IS and the relationship between the areas of hardware and software. Based on the evaluation of the current state and its comparison to the balanced optimal state for the present day as well for the future, the new possible directions and strategies of further development of the IS in the company are being proposed. I see the best exploitation of the methodic HOS2009 in the company in the support of managerial decisions with impact on: the discovery of potentially problems within the scope of IS of the company, the design of a possible course of development useful for their solution, but also the usage of the methodic as a simple control mechanism.
