Darbo tikslas: Tarptautinių pervežimų organizacijos sisteminio projekto kūrimas. Teorinėje dalyje atlikau organizacijos, kaip socialinės – ekonominės sistemos, analizę. Visų pirma analizavau sistemos sampratą bei jos atsiradimą sąlygojančius veiksnius, pagrindinių sistemos sąvokos tyrėjų mokslinius darbus, sistemų klasifikaciją. Toliau nagrinėjau sistemos pagrindines charakteristikas – funkcinę, morfologinę, procesinę. Šių charakteristikų nustatymo pagrindinius kriterijus. Atskirai nagrinėjau valdymo sistemos sandaros ypatybes. Analitinėje dalyje sudariau organizacijos sisteminio projektavimo metodiką. Aprašiau, kaip turi būti nustatomos organizacijos funkcijos, projektuojama jos sandara, charakterizuojami joje vykstantys procesai. Projektinėje dalyje, naudodama savo parašytą sisteminio projektavimo metodiką, sukūriau tarptautinių pervežimų organizacijos sisteminį projektą. Nustačiau kokias funkcijas atliks kuriama organizacija, suprojektavau jos organizacinę sandarą, valdymo struktūrą, charakterizavau joje vykstančius procesus. / The aim of the paper was the creation of the systemic project for the international transit organization. In theoretical part the analysis of the organization as a social-economical system was done. Firstly, I analyzed the conception of the system and factors that determine its occurrence, as well as the main works of the researchers and classification of the systems. Further, I scrutinized the main characteristics of the system, which are as follows: functional, morphological and procedural, and criterions for identification of those characteristics. The structure of the system was analyzed separately. In the analytical part, I composed the methodology for systemic engineering of the organization, described how the functions of the organization are to be determined, how its architecture is designed and how processes occurring within the organization are characterized. In the design part, using my own methodology, I created the systematic project of the international transit organization, identified its functions, planned its organizational structure, leadership structure and characterized the processes occurring within the organization.

The aim of this work is to investigate projection operator method of deriva- tion of equations of motion for reduced density matrix and apply it to a model open quantum system. We gradually pass from quantum mechanical model of a molecule with one vibrational degree of freedom to an example of open quantum system relevant in the theory of nonlinear spectroscopy. In the thesis we present results of numerical simulations of the time evolution of the open quantum system performed with a program written for this purpose. We are specially concerned with simulations of the solution of the time-convolutionless generalized master equation up to the a second order of the perturbation expan- sion, and we show that under certain conditions it provides an exact solution of the problem. The text also contains derivation of the recurrence relations for the Franck-Condon factors for the most general case of two quantum harmonic oscillators in one space dimension, i. e. transformation matrix between two bases of the L2 (R) space determined by the solutions of the time-independent Schrödinger equation appropriate for these oscillators. 1
