Excellence in manufacturing systems has been recognized as one of the main factors behind the success of industrial companies or production companies. New technology for manufacturing processes plays a significant role in this process. Achieving the potential of technological innovations in production, however, requires a wide range of management, as well as engineering issues related to the system...
Mathematical morphology supplies powerful tools for low level image analysis, with applications in many areas. In this paper, the development of a novel reconfigurable hardware using a genetic algorithm and a pipeline architecture is proposed for the task of shape recognition in binary images. For the recognition process, a large sized convex structuring element representing the object shape to be...
Scheduling of machines and AGVs in Flexible Manufacturing Systems involves modeling and searching methodology in a wide solution space. In this work the search for scheduling occurs by genetic algorithm and simple AGV dispatching rules. Modeling occurs in Timed Petri nets in time of fitness evaluation, considering the input buffers of machines, AGVs, and flags also control the use of these buffers,...
This paper aims to use an extension of Petri nets, Fuzzy Coloured Petri nets to model a manufacturing system and to solve conflicts that occur when processes are competing for the same resources. System resources, part routing and buffers are modeled in Coloured Petri Nets and a fuzzy rule-based system is modeled using Fuzzy Petri Nets. Conflicts may occur at the load station, input and output buffers...
This paper proposes an Ant Colony optimization approach for production scheduling problem in a flexible manufacturing system. The problem is treated on two perspectives, based on the modeling and the search method. The problem modeling is characterized by a high-level problem description, using the production routes as a way to represent the states of the solution space. About the collaboration concept...
