Coordination in multi-agent system is very essential, in order to perform complex tasks and lead MAS towards its goal. Also, the member agents of multi-agent system should be autonomous as well as collaborative to accomplish the complex task for which multi-agent system is designed specifically. Contract-Net Protocol (CNP) is one of the coordination mechanisms which is used by multi-agent syste...

The Contract Net Protocol (CNP) [Smith, 1980] assigns a subtask to agents which are involved in multiagent problem solving. Although the logical aspects of the negotiation protocol have been analyzed, the properties of protocol dynamics remain unclear. This paper introduces our quantitative analysis of protocol dynamics which is essential for constructing continuous reaitime applications. We ca...

The Contract Net Protocol (CNP) is a widely used task allocation protocol in Multi-Agent Systems. It is fast, flexible and has low communication costs. However it is limited in some issues and has shortcomings if the setting for task assignment is more complicated. This paper addresses those limitations and summarizes extensions that has been published over the years. It also evaluates the prot...

| Tools for selective proactive as well as reactive information retrieval, information extraction , information organization and assimilation , knowledge discovery using heterogeneous, distributed knowledge and data sources constitute some of the key enabling technologies for managing the data overload and translating recent advances in automated data acquisition, digital storage, computers and...

Because of high speed, efficiency, robustness and flexibility of multi-agent systems, in recent years there has been an increasing interest in the art of these systems. In competitive multi agent systems, a mechanism is required via which the agents can come to reach an agreement. Contract net protocols are one of the wellknown negotiation protocols in multi-agent systems. In contract net proto...

This paper deals with a multi-agent-based interval type-2 fuzzy (IT2F) expert systemfor scheduling steel continuous casting. Continuous caster scheduling is a complex and extensiveprocess that needs expert staff. In this study, a distributed multi-agent-based structure is proposed as asolution. The agents used herein can cooperate with each other via various communication protocols.To facilitat...

Abstract. This paper builds an efficient agent-based flexible scheduling for real-world manufacturing systems. Considering the alternative processes and alternative machines, the allocation of manufacturing resources is achieved through negotiation among the job and machine agents in a multi-agent system (MAS). Ant Colony Intelligence (ACI) is proposed to be combined with Contract Net Protocol ...

The flexible architecture provided by holonic manufacturing systems (HMS) poses challenges in planning and control of production processes. The challenges are due, in part, to the loosely coupled structure of holons and also to the complex interactions among holons. Development of new methodologies is required to optimize the holonic processes in HMS to achieve the objectives. In this paper, we...

We use a Contract Net protocol for comparing various strategies for trusting other agents. We introduce three classes of trustiers: a random trustier, a statistical trustier, and a cognitive trustier.

Composition of processes for virtual enterprises is a significant issue. Although the flexible architecture provided by holonic manufacturing system (HMS) paves the way for adaptive composition of virtual enterprise processes, it also poses challenges in planning processes for virtual enterprises. The challenges are due, in part, to the loosely coupled structure of holons and also to the comple...
