Modeling a holonic agent based solution by Petri nets

Computer Science and Information Systems, 2012

This contribution refers holonic manufacturing execution systems and highlights the way a proper modeling method - Petri nets - makes evident certain problems that can appear when agents have to simultaneously treat more goals. According to holonic organization the planning phase is mainly dependent on finding an appropriate resource allocation mechanism. The type of weakness is established by means of the proposed Petri net models and further proved by simulation experiments. A solution to make the holonic scheme avoid a failure in resource allocation is mentioned, too.

Job Schedule in Flexible Manufacturing Systems Using Aggregated Models

IFAC Proceedings Volumes, 2007

Starting from the graph of the detailed problem, a method of optimization the task schedule is emphasized. In order to obtain a minimum time for the project execution together the fulfilment of resource constraints, the detailed model is aggregated, optimized from the point of view of the graph height and cardinality and finally the solution is disaggregated. The method is applied in the case study of a Flexible Manufacturing System for an assembly project that is used for educational purposes, emphasizing the results.

The control scheme is a holonic one, namely a PROSA reference architecture is considered. Some principles regarding the way the coordination and planning mechanisms have to be adapted for an enhanced sensorial integration are investigated. These refer a plan-space planning approach that operates with partially specified plans, and

Based on certain abstraction and sensing procedures the problem specification, the robots' environment and their motion capabilities can be transposed to a finite state representation. The distributed nature of the considered application involving two robots and the reduced computation resources of individual robots conducted us to attaching robot deliberative components in an agent based implementation using a specialized software platform, namely JACK. The obtained multiagent system creates a framework for an approach that allows the interleaving of planning and execution. The agents apply an A* type bidirectional search to find the movement plan. The developed coordination protocol permits correct path generation even when the environment is changing while the robots are moving. The computational complexity of the proposed approach is low, and the system operation is supported by simulation experiments.

The system was developed and tested on a flexible manufacturing cell endowed with industrial equipment. Artificial intelligence methods and tools were used, namely expert systems, multiagent systems and rule based programming. The approach that combines centralized planning and monitoring with de-centralized and distributed decision making and control subsystems aims at a high flexibility and autonomy.

While it is hard to find a unique architecture for all the applications involving mobile robots, specific approaches can provide suitable solutions. Thus, three distinct structures are discussed, all making use of certain artificial intelligence techniques. They address the use and integration of artificial vision, a planning approach based on temporal logics, and a multi agent scheme. The three methods refer cases of mobile robots evolving in environments where various types of sensorial information can be obtained. Each of the proposed solutions determines advantages when it is used for a certain class of tasks.
