Item Ekonomiczne zastosowania maszyn liczących(Wydział Prawa i Administracji UAM, 1967) Abt, StefanThe introduction of the article is a classification of calculating machines together with a discussion on those features of each group of machines important to operators. The different groups are: I mechanical machines (two and four operational, and accounting and invoicing machines), II calculating machines — analitical (with auxilliary, basic and complimentary partitions), III computers (analogical and digits, among which are machines for converting data numerical calculations and machines for operating and controlling processes). After a general review of various types of machines we come to the point of discussion — economical application of calculating machines, the term economical being in the sense of economize. Statics show the advantage of using various types of machines, an advantage which grows, with the increasing degree of mechanism and automation. The difficult in gauging all the economical effects gained must be emphasized. The economical application of calculating machines can also be understood in the sense applied in economy or as used by economists. The second part of this article is devoted to this problem. Whereas non-electronic machines are used mainly in mechanization of records in enterprises, with electronic machines macroeconomics can be differentiated from microeconomics. In each of them a different approach is necessary to convert data in comparison to numerical calculations. By specifying the concrete applications, within these four groups, in the work in enterprises and institutes, we can asses the posibilites of applying the latest achievements in automatization of calculations. In discussing the anticipated trends of development of electronic digit machines the author portrays the perspectives in this field and the -tasks facing economists.Item Możliwości symulacji procesów przemysłowych na elektronicznych maszynach cyfrowych(Wydział Prawa i Administracji UAM, 1969) Abt, StefanThe aim of the article is to attract the attention of the economists to the neglected appliance of computers, that are exploited to simulation of the economic processes. Under the simulation we understand not only the investigations, whose aim is to reduce the scale of time but also representation of some elements of the object, phenomenon, system or surrounding that enables the examination of the object. It can take place in the case of solving different mathematical problems (as for instance calculation of integrals), where in spite of analytical methods one uses Monte Carlo method and also in the examination of different economic processes. Different computers can be used as compositions that simulate the fate event or substitute the execution of the experiment. In the economical sciences it is a thing of great importance. The possibilities of simulation of the economical processes are presented in many examples from the problems of mass services, where for instance one describes the length of a queue or the optimal amount of staff across the simulation of behaviour of fictitious productive problems across the organizational systems, finishing with models that contain the factor of time. On the background of possibilities there are shown the perspectives of simulation of the economical processes.Item O kontroli jakościowej żywności(Wydział Prawa i Administracji UAM, 1965) Abt, StefanItem Zmiany w strukturze spożycia ludności(Wydział Prawa i Administracji UAM, 1970) Abt, StefanThe work of the author is the attempt of showing the possibilities of statistical calculation of the individual structure oï consumption that is necessary to establish the vector of needs. The analysis of the data of the past years became the starting-point to calculate the tendencies of development and to estblish at their basis the future structure. The autor compared the consumption of population of France and its structure in the years l949 - 1965 at the basis of the data of the Statistical Institute (INSEE) and the data of consumption in Poland in the years 1959 - 1965. The various formulation of the data made possible different versions of establishment of the tendencies of development and the methods of calculation of the future structure of consumption. In further analysis there was taken into account the influence of social groups on structure of consumption. The autor indicated the consequences caused by differentiation of the structure of consumption and showed the limited possibilities of utilization of the statistical data owing to so far reaching differentiation of the examined community. In the last part of the work there were showed at the example of changes in consumption of some products, the differences between France and Poland at the background of other countries. These values were admittedly established by estimation but they confirmed to some extend the changes in the structure of consumption that could be observed in whole groups of articles.Item Znaczenie podejmowania optymalnych decyzji w badaniu jakości produktów(Wydział Prawa i Administracji UAM, 1962) Abt, Stefan
