Optimized Models of Modes Choice for Displacement of technical Systems Objects

The effectiveness of working processes accomplished by various technological machines to a large extend depends on working quality of supply, transporting and orientating mechanisms which are very often produced as positional hydro-mechanical systems. The choice of their best type and regimes of work requires construction and analysis of models of their optimum steering which are complicated by nonlinearness, multy-criterialness of problem and also by occasional outbreaks of parameters and moments of steering regime changing. It was developed the common structure of such systems allowing within common scheme to vary the complexity degree of PHMS and the methods of inhibitory efforts supplement. For some systems which are complicated in series (from two-measured linear system to nine-measured non-linear) puzzles of the most fast zero-ambit getting are solved and two-criterial problems are analyzed. (T-min-speed, Z(T)- accuracy). There are suggested the computing procedures of optimum PHMS synthesis. The effectiveness of accepted methods of solving is asserted by the analogy of the results of gradually complicated models investigation and by their good analogy with the natural experiment. It was exposed the sense of heuristic methods of improving of approximately optimum steering, their elaboration on the base of theoretical models. The basic methods of optimum PGMS construction were also nominated

Die optimale Projektierung der metallverarbeitenden Betriebe

Es wird das gemeine Schema der Projektierung, die die Analyse des Marktes einschließt, betrachtet, die Einschätzung der Nomenklatur und des Umfanges des Produktionsausstoßes der Erzeugnisse, und die Schlüsselaufgabe der Wahl der Regimes der Bearbeitung. Die letzte Aufgabe wird - konkretisiert es werden die Formeln berichtet und die Algorithmen der Optimierung nach den Kriterien der Produktivität und den Selbstkostenpreisen. Es sind die Formeln für die Produktivität der Systeme mit der flexiblen Verbindung, präzisiert sowie die Abhängigkeiten für die Standhaftigkeit bei den kleinen Geschwindigkeiten des Schneidens. Die Schlüsselwörter: der Markt, die Regimes der Bearbeitung, die Produktivität, der Selbstkostenpreis, die Optimierun

THE RATING OF SCIENTIFIC-PEDAGOGICAL WORKERS AND SCIENTIFIC-EDUCATIONAL STRUCTURAL SUBDIVISION AT UNIVERSITY

Одной из актуальных задач вузовского управления сегодня является разработка и использование строгих количественных критериев для оценки деятельности научно-педагогических работников и научно-образовательных структурных подразделений, вузов и научных учреждений в целом. Как правило, в этих целях используются различные рейтинги, существенными недостатками которых являются субъективизм в назначении весов показателей и отсутствие сведений о принадлежности объектов к множеству Парето. Разработан и апробирован более объективный метод сравнительной оценки (рейтинга) научно-образовательной деятельности работников и структурных подразделений, который может быть использованы в практике, в частности, управления персоналом и структурными подразделениями вузаOne of actual problems of high school management today is development and use of strict quantitative criteria for an estimation of activity of scientific and pedagogical workers and scientifically-educational structural divisions, high schools and scientific institutes as a whole. As a rule, in these purposes various ratings which essential lacks are subjectivity in purpose of weights of parameters and absence of data on an accessory of objects to set Pareto are used. More objective method of a comparative estimation (rating) of scientifically-educational activity of workers and structural divisions which can be used in an expert, in particular, managements of the personnel and structural divisions of high school is developed and approved
