Although evolutionary algorithms have often been used to address VRPs and VRPTWs [1], applications to other routing problems such as period routing and inventory routing are less common. In this paper, a versatile hybrid evolutionary algorithm is developed that can be used for cyclic inventory routing and a variety of capacitated and periodic vehicle routing problems. First, a random insertion ...

The development towards decentralized manufacturing systems aims at increased flexibility and robustness by maintaining the level of productivity. In order to meet these requirements, human-robot collaboration is considered as basic framework within future intelligent manufacturing cells. For industrial implementation, the concepts of smart production need to be refined and their benefits have ...

Over the last decade, the manufacturing landscape has changed worldwide. Parts of the traditional manufacturing activities havemoved toworld regions, away from the long-established industrial centres in Western Europe, North America and Japan. The demand for goods has been increased and so has the demand for natural resources and energy. However, since resources and energy are finite, new ways ...

Produktionssysteme werden laufend angepasst, weil sich Änderungen an den Produkten ergeben, Kapazitäten aufgrund schwankender Bedarfe neu justiert werden müssen oder rationellere Fertigungstechnologien eingesetzt werden. In der Praxis führen Änderungen an Produktionsanlagen nicht nur zum räumlichen ‚Verschieben’ von Anlagen innerhalb eines Werkes, sondern vor allem zu Anpassungen an der steuern...

5-axis machining operations bring new challenges for predicting cutting forces. Complex tool workpiece engagements and tool orientations make it difficult to adapt 3-axis process models for 5-axis operations. A new model is developed to predict cutting forces with arbitrary tool/workpiece engagement and tool feed direction. A discretization approach is used, in which the tool is composed of mul...

Abstract Objective of this contribution is to present the use Model-based Systems Engineering within engineering design community. Based on a differentiation between SE and MBSE, definition three core MBSE elements, namely modelling method, language, tool as well major aspects consistent system model (requirements, behaviour, structure) structured review conducted, focussing understanding motiv...
