Distributed processing offers the potential for high speed, reliable computation, together with a means to handle applications that have a natural spatial distribution. In this paper, distributed processing is defined as processing that is characterized by physical decomposition of the processor into relatively Independent processor nodes. Recent advances in LSI technology, expected to result i...

HE MOST comprehensive indicator of economic performance in the nation in a given year is gross national product (CNP). Changes in CNP reflect both changes in prices and changes in the physical volume of output. CNP adjusted for price level changes is generally accepted as a reliable indicator of growth in the nation’s total production and is used by economic analysts to indicate whether the eco...

Negotiation is a fundamental mechanism in distributed multi-agent systems. Since negotiation is a time-spending process, in many scenarios agents have to take into account the passage of time and to react to uncertain events. The possibility to decommit from a contract is considered a powerful technique to manage this aspect. This paper considers interactions among self-interested and autonomou...

In this paper, we investigate in the applicability of the Contract Net Protocol negotiation (CNP) in the field of the dynamic transportation. We address the optimization of the Dynamic Pickup and Delivery Problem with Time Windows also called DPDPTW. This problem is a variant of the Vehicle Routing Problem (VRP) that may be described as the problem of finding the least possible dispatching cost...

Grid scheduling, that is, the allocation of distributed computational resources to user applications, is one of the most challenging and complex task in Grid computing. In this paper, we give a quantitative description of a tender/contract-net model. The performance of the proposed market-based approach is experimentally compared with a simple round-robin allocation protocol. Key–Words: Grid co...

Earth observation resources are becoming increasingly indispensable in disaster relief, damage assessment, and other related domains. Many unpredictable factors, such as changes task requirements, bad weather, resource malfunctions, may cause the scheduled scheme to become infeasible. In these cases, it is crucial promptly reformulate high-quality schemes while exerting minimal negative effects...

Abstract. The Contract Net Protocol was developed to facilitate contract negotiation in MultiAgent Systems, between an auctioneer and many bidders. It is therefore important to analyse the protocol to ensure that it terminates correctly and satisfies other important properties. There have been few attempts to model and analyse this protocol in the literature. The main paper on its verification,...

The MARS system is described which models cooperative scheduling witldn a society of shipping companies as a multiagent system. Emphasis is placed on the functionality of the system as a whole -the solution of the global scheduling problem emerges from local decision-making and problem-solving strategies. An extension of the contract net protocol is presented; we show that it can be used to obt...
