A Content Language for a Hierarchically Organized Multi- Agent-System for Production Control
نویسندگان
چکیده
In this paper, we describe a content language for a hierarchically organized production control system in semiconductor manufacturing. The semiconductor manufacturing domain is characterized by re-entrant product flows, sequence-dependent setup-times, prescribed due-dates, a diverse product mix, a mix of different process types including batch processes and preventive maintenance issues caused by complex technological processes. Starting from a hierarchical decomposition of the manufacturing system, we use an agent-based architecture for implementing the resulting production control system. In order to coordinate the autonomous entities of the hierarchy, we suggest a content language that is appropriate to the hierarchical control approach. We describe a prototypical implementation of the suggested language. We illustrate the use of our content language by means of an example scenario.

Simulation-based assessment of machine criticality measures for a shifting bottleneck scheduling approach in complex manufacturing systems
In this paper, we describe adaptation techniques for a hierarchically organized multi-agent-system (MAS) applied to production control of complex job shops. The system architecture of the production control system is based on three different control layers. The mid layer implements a distributed shifting bottleneck type solution procedure. The shifting bottleneck heuristic decomposes the overal...
متن کاملA Self-organized Multi Agent Decision Making System Based on Fuzzy Probabilities: The Case of Aphasia Diagnosis
Aphasia diagnosis is a challenging medical diagnostic task due to the linguistic uncertainty and vagueness, large number of measurements with imprecision, inconsistencies in the definition of Aphasic syndromes, natural diversity and subjectivity in test objects as well as in options of experts who diagnose the disease. In this paper we present a new self-organized multi agent system that diagno...
متن کاملNeural Network Based Multi-agent Information Retrieval System
Agent-based information retrieval systems have gained great attentions due to the proliferation of readily available, but overwhelming information on the distributed network environments such as the Web. Agents are often developed not in isolation but as part of a multi-agent system. In this paper, we present a neural network based multi-agent, especially hierarchically organized, information r...
متن کاملAutomatic Generation of a Multi Agent System for Crisis Management by a Model Driven Approach
Considering the increasing occurrences of unexpected events and the need for pre-crisis planning in order to reduce risks and losses, modeling instant response environments is needed more than ever. Modeling may lead to more careful planning for crisis-response operations, such as team formation, task assignment, and doing the task by teams. A common challenge in this way is that the model shou...
متن کاملLoad-Frequency Control: a GA based Bayesian Networks Multi-agent System
Bayesian Networks (BN) provides a robust probabilistic method of reasoning under uncertainty. They have been successfully applied in a variety of real-world tasks but they have received little attention in the area of load-frequency control (LFC). In practice, LFC systems use proportional-integral controllers. However since these controllers are designed using a linear model, the nonlinearities...
