Difficulties in solving problems of planning and recording for organization information systems

The solution of problems of planning and operational records in the modern information systems still introduce some problems. The especially difficult specified problems dare in cases when technological process has stochastic character. Technological processes influencing planning problems and operational records have been considered in the article. Variants of the production planning model and the organization of constructing systems for operational records have been discussed.

Information system «University-Employer»

The features of the educational process under conditions of transition to three-tier training system are considered. The contradictions between the graduates expectations and labor market characteristics are stated. A version of an information system is suggested that allows the student-employer relationship establishing and correct competencies taking into account the real needs of the labor market.

On the efficiency of information systems and the method of its estimation

The introduction of information systems (IS) in enterprise management, as experience shows, quite rarely leads to increase in nomenclature of processed data. The obtained IS-related economic effectiveness is usually lower than for other innovations in production. For the first time it was noted by Academician V. A. Trapeznikov, who showed that the causes of this are not temporary or technology- related, but have fundamental basis, defined by the nature of information processes. The work proposes the common approach for estimating the effectiveness and optimization of main parameters of production-technological information systems; we also put forward a method for estimating the maximum (economically feasible) dimensions of mathematical programming problems that implement the strategic functions of enterprise management. We also show major dependencies both for optimization of parameters and estimation of IS local functions efficiency, as well as IS strategic functions. The proposed methods are probably of most interest for the enterprises in machine-building industry, which manufacture high-complexity products. The experience of creating IS for such objects showed that the customer is unable to formulate complete and accurate requirements for the future system. That is why the process of task setting and software development inevitably becomes iterative. The analysis of the results of the current stage may lead to changes in any previous ones, to the extent of creating new versions. To manage such an unpredictable process, it is necessary to estimate full project cost and its effectiveness based on express-inspection of the enterprise. This method, which is using advantages of macro-approach to describing complex objects, in fact allows the completion of this goal even before any works have started. In addition, quite limited amount of available data is required for calculations.
