Abstract In this article, we aim to analyze a mathematical model of tumor growth as a problem of fractional optimal control. The considered fractional-order model describes the interaction of effector-immune cells and tumor cells, including combined chemo-immunotherapy. We deduce the necessary optimality conditions together with implementing the Adomian decomposition method on the suggested fractional-order optimal control problem. The key motive is to perform numerical simulations that shall facilitate us in understanding the behavior of state and control variables. Further, the graphical interpretation of solutions effectively validates the applicability of the present analysis to investigate the growth of cancer cells in the presence of medical treatment.

Industrieroboter sind zu einer Schlüsseltechnologie in der Produktion geworden. Mit dem steigenden Einsatz von diversen Robotersystemen wächst das Bedürfnis, deren Kompatibilität zu steigern. Heutzutage gibt es keine Technologie in der Industrie, die eine standardisierte Programmierung und Steuerung von verschiedenen Robotersystemen gewährleisten kann. Dieser Fachbeitrag präsentiert ein einheitliches Konzept, welches die Anwendung von herstellerneutralen Roboterapplikationen ermöglicht.   Industrial robots have become a key technology in production. The increasing use of various robotic systems, raises the need to enhance their compatibilit.y Nowadays, there is no technology in the industry to guarantee a standardized programming and control of different robot systems. This article presents a concept enabling the use of manufacturer-independent robot applications.
