The proposed Competitive Contract Net Protocol has been designed to facilitate a flexible cooperation in competitive multi-agent environments and to support automated or semi-automated negotiations in competitive domains. The protocol is based on FIPA standards. The protocol covers not only the phase of contracting the commitments, but also allows for a decommitment negotiation and contract ter...

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 well-known negotiation protocols in multi-agent systems. in contract net pro...

In this paper we present a fairly complex example of how the social model for agent conversations based on social commitments we have developed in the past formally supports the implementation of conversations for the Contract Net Protocol.

Negotiation is a technique through which two agents having conflicting interests reach an agreement that is beneficial for both of them. Argumentation-based negotiation is a better form of negotiation where one negotiating agent argues with another to justify its position and influences the other agent to follow it. This increases the likelihood and quality of agreement in a negotiation process...

In this paper, we present a new environment of negotiation in a multi-agents system for the electronic market. Our environment presents two protocols of negotiation, namely; the protocol of negotiation by auction and the contract net protocol. The choice of the protocol to be used, is made according to the type of product negotiate, for certain products, we use the auction, and for others we us...

This paper presents the effect of adaptively introducing appropriate strategies into the award phase of the contract net protocol (CNP) in amassivelymulti-agent system (MMAS).

Although the contract net protocol answers some of the questions in cooperative distributed problem solving (CDPS), it raises many others that CDPS researchers are still trying to answer. In contract net protocol, an agent may play the role of a manager or a bidder. Without a coordination mechanism, a manager may acquire excessive resources from the bidders in forming a collaborative network to...

Holonic manufacturing systems requires a robust and effective mechanism to reorganize available resources to cope with uncertainties to achieve the production goal. This paper combines the contract net protocol and Petri net to adaptively synthesize Petri net to control holonic manufacturing systems. The main results include: (1)a multi-agent model for holonic manufacturing systems based on con...

In response to the problems that have arisen regarding the terminology and concepts of agent-oriented systems, previous work has described a formal framework for understanding agency and autonomy. In this paper we outline the framework and re ne it by adding further levels of detail to develop a formal model of the Contract Net Protocol. The model serves to make precise both the operations of n...

In this paper, we investigate in the application of the Contract Net negotiation Protocol (CNP) to deal with a dynamic hard transportation problems. Our interest in the Multi-agent negotiation approaches accounts for its proved suitability with dynamic and uncertain domains [8][9]. We address the resolution of the uncapacitated-multi-vehicle-Dynamic Pickup and Delivery Problem with Time Windows...
