  • The concept of switched reluctance machines (SRMs) was established as early in 1838 by Davidson and was used to propel a locomotive on the Glasgow–Edinburgh railway near Falkirk [1]. However, the full potential of the motor could not be utilized with the mechanical switches available in those days. The advent of fast-acting power semiconductor switches revived the interest in SRMs in the 1970s when Professor Lawrenson’s group established the

  • Stochastic Optimization Algorithms have become essential tools in solving a wide range of difficult and critical optimization problems. Such methods are able to find the optimum solution of a problem with uncertain elements or to algorithmically incorporate uncertainty to solve a deterministic problem. They even succeed in “fighting uncertainty with uncertainty”. This book discusses theoretical aspects of many such algorithms and covers their application in various scientific fields

  • Lagerhaltung dient im Allgemeinen der Anpassung von Angebots- und Nachfrageprozessen, die nicht zusammen passen. So beschreibt es Paul Zipkin in seinem Buch Foundations of Inventory Management [94] sehr treffend. Ziel ist es also die Produktions- oder Beschaffungsabläufe mit den Nachfrageprozessen zu verheiraten, ohne dass es zu Problemen in den Kundenbeziehungen kommt, weil nachgefragte Teile nicht geliefert werden können. Lager dienen als Puffer, der in Zeiten geringer Nachfrage die Überproduktion aufnimmt und in Zeiten besonders starker Nachfrage die Unterproduktion ausgleicht.
