From production and marketing to financial management, a manager has to assess various costs imposed by uncertainty. The economist analyzes the role of incomplete and too often imperfect information structures on the optimal decisions made by a firm. The need for understanding the role of uncertainty in quantitative decision models, both in economics and management science provide the basic motivation of this monograph. The stochastic environment is analyzed here in terms of the following specific models of optimization: linear and quadratic models, linear programming, control theory and dynamic programming. Uncertainty is introduced here through the para meters, the constraints, and the objective function and its impact evaluated. Specifically recent developments in applied research are emphasized, so that they can help the decision-maker arrive at a solution which has some desirable charac teristics like robustness, stability and cautiousness. Mathematical treatment is kept at a fairly elementary level and applied as pects are emphasized much more than theory. Moreover, an attempt is made to in corporate the economic theory of uncertainty into the stochastic theory of opera tions research. Methods of optimal decision rules illustrated he re are applicable in three broad areas: (a) applied economic models in resource allocation and economic planning, (b) operations research models involving portfolio analysis and stochastic linear programming and (c) systems science models in stochastic control and adaptive behavior.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 300 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Modern sonography makes possible the detection of small and subtle changes in the normal echo pattern. These may represent significant pathological changes which can not al ways be fully revealed by the echo pattern alone. There is, therefore, an increasing need for the supplement of the ultra sonically guided percutaneous puncture, which can be per formed with great accuracy and with virtually no risk. Also, ultrasonically guided puncture has proven invaluable for a wide variety of therapeutic purposes. The first percutaneous puncture guided by ultrasonic scanning using a specifically designed transducer was per formed in 1969 at the ultrasonic laboratory in Gentofte, now Herlev, Hospital, Copenhagen. The idea was based on a punc ture transducer described and used by Kratochwill for punc ture under the guidance of the ultrasonic A-presentation tech nique. The development in the field formed the basis of the First International Conference on Ultrasonically Guided Puncture at Herlev Hospital in 1978 sponsored by The Danish Society of Diagnostic Ultrasound. The knowledge and experience of the speakers at that conference was compiled in the book 'Ultrasonically Guided Puncture Technique' published in 1980. Since then the Society has sponsored a conference at the same place in 1980 and 1983, the latest conference being termed 'Third International Conference on lnterventional Ultrasound'.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 188 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Diese Einführung in die Programmiersprache COBOL ist entstanden aus mehreren Kursen, welche am Rechenzentrum der Universität Bremen für Hörer aller Fachbereiche und an der Volkshochschule Bremen im Rahmen der beruflichen Weiterbildung abgehalten worden sind. Das Ziel dieser Kurse bestand darin, den Teilnehmern die grundlegenden Sprach elemente von COBOL zu vermitteln und bei der Programmerstellung den Zielvorstellun gen des 'Strukturierten Programmierens' Rechnung zu tragen. Dazu wird ein Lösungs algorithmus zunächst graphisch - in Form eines Struktogramms - dargestellt und an den in COBOL zur Verfügung stehenden Sprachelementen kodiert. schließend mit Dabei sind die Anwendungsbeispiele betont einfach gehalten, so daß keine besonderen Kenntnisse aus dem Bereich der administrativen und kommerziellen Anwendungen - dem Haupteinsatzgebiet von COBOL - erforderlich sind. Der Leser dieser Einführung braucht über keine Vorkenntnisse aus dem Bereich der Elektronischen Datenverarbeitung zu verfügen, da die wichtigsten Begriffe zusammen mit den Elementen von COBOL vermittelt werden. Nach der Lektüre dieser Einführung wird der Leser in der Lage sein, selbständig COBOL-Programme zu entwickeln und auf einer Datenverarbeitungsanlage ablaufen zu lassen. Schon mit den Grundkenntnissen, welche in den ersten drei Kapiteln vermittelt wer den, kann der Leser einfache Aufgaben selbständig lösen. Zur Lernkontrolle und um sich in der Fertigkeit des Programmierens zu üben, sollte sich der Leser auch stets um die Lösung der Aufgaben bemühen, welche jeweils am Ende eines Kapitels angegeben Als Hilfestellung stehen ihm dabei die Ausführungen im Lösungsteil zur Verfü sind. gung. 292 pp. Deutsch.
