Systematic Solution

Dieser Beitrag stellt einen Algorithmus für das Job-shop-Scheduling-Problem vor, welcher den Lösungsraum indexiert und eine systematische Navigation zur Lösungssuche durchführt. Durch diese problemadäquate Aufbereitung wird der Lösungsraum nach bestimmten Kriterien vorzustrukturiert. Diese Problemrepräsentation wird formal beschrieben, sodass ihre Anwendung als Grundlage für ein navigationsorientiertes Suchverfahren dienen kann. Ein vergleichender Test mit anderen Optimierungsansätzen zeigt die Effizienz dieser Lösungsraumnavigation.   This paper presents an algorithm for the job-shop scheduling problem indexing the solution space and performing systematic navigation to find good solutions. By this problem-adequate preparation of the solution space, the solution space is pre-structured according to certain criteria. This problem representation is formally described so that its application can serve as a basis for a navigation-oriented search procedure. A comparative test with other optimization approaches shows the efficiency of this solution space navigation.

The article discusses the main directions of development of cosmonautics, which have an impact on ensuring the connectivity of the territories of the Russian Federation. The key role of such areas of space activity as space navigation, space communications, remote sensing of the Earth, applied and fundamental research in space is shown. An analysis of the development trends of applied cosmonautics, existing problems and ways to solve them is conducted: increasing the scientific space and remote sensing group of the Earth, methods of improving the accuracy of positioning, availability, noise immunity of space navigation, etc.
