Die langwierige manuelle Entwicklung von Greifsystemen wird durch das im Beitrag vorgestellte Softwaresystem automatisiert. Basierend auf dem Anforderungsprofil werden die einzelnen Bereiche der Softwarelösung vorgestellt und deren Funktionsweise erläutert. Am Beispiel der Gruppierung von Spannpunkten für Türmontagesysteme durch multikriterielle Optimierung wird das Potenzial für die breitere Anwendung der Softwarelösung in flexiblen und modularen Anlagen gezeigt.
The software system presented in this paper allows for automating the tedious manual development of gripping systems. Based on a requirements profile, the individual areas of the software solution are presented and their functionality is explained. The example of grouping clamping points for door assembly systems using multi-criteria optimization, points out the potential for a broader application of the software solution in flexible and modular systems.
Motivated by a routing problem faced by banks to enhance their encashment services in the city of Perm, Russia, we solve versions of the traveling salesman problem (TSP) with clustering. To minimize the risk of theft, suppliers seek to operate multiple vehicles and determine an efficient routing; and, a single vehicle serves a set of locations that forms a cluster. This need to form independent clusters—served by distinct vehicles—allows the use of the so-called cluster-first route-second approach. We are especially interested in the use of heuristics that are easily implementable and understandable by practitioners and require only the use of open-source solvers. To this end, we provide a short survey of 13 such heuristics for solving the TSP, five for clustering the set of locations, and three to determine an optimal number of clusters—all using data from Perm. To demonstrate the practicality and efficiency of the heuristics, we further compare our heuristic solutions against the optimal tours. We then provide statistical guarantees on the quality of our solution. All of our anonymized code is publicly available allowing extensions by practitioners, and serves as a decision-analytic framework for both clustering data and solving a TSP.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
