Domain Monotonicity and the Performance of Local Solutions Strategies for CDPS-based Distributed Sensor Interpretation and Distributed Diagnosis

The growth in computer networks has created the potential to harness a great deal of computing power, but new models of distributed computing are often required. Cooperative distributed problem solving (CDPS) is the subfield of multi-agent systems (MAS) that is concerned with how large-scale problems can be solved using a network of intelligent agents working together. Building CDPS systems for real-world applications is still very difficult, however, in large part because the effects that domain and strategy characteristics have on the performance of CDPS systems are not well understood. This paper reports on the first results from a new simulation-based analysis system that has been created to study the performance of CDPS-based distributed sensor interpretation (DSI) and distributed diagnosis (DD). To demonstrate the kind of results that can be obtained, we have investigated how the monotonicity of a domain affects the performance of a potentially very efficient class of strategies for CDPS-based DSI/DD. Local solutions strategies attempt to limit communications among the agents by focusing on using the agents' local solutions to produce global solutions. While these strategies have been described as being important for effective CDPS-based DSI/DD, they need not perform well if a domain is nonmonotonic. We had previously suggested that the reason they have performed well in several research systems was that many DSI/DD domains are what we termed nearly monotonic. In this paper, we will provide quantitative results that relate the performance of local solutions strategies to the monotonicity of a domain. The experiments confirm that domain monotonicity can be important to consider, but they also show that it is possible for these strategies to be effective even when domains are relatively nonmonotonic. What is required is that the agents receive a significant fraction of the data that is relevant to their subproblems. This has important implications for the design of DSI/DD systems using local solutions strategies. In addition, while the work indicates that many DSI/DD domains are likely to be nearly monotonic according to our original definitions, it also shows that these measures are not as predictive of performance as other measures we define. This means that near monotonicity alone does not explain why local solutions strategies have performed well in previous systems. Instead, a likely explanation is that these systems typically involved only a small number of agents.

基于语义近似逼近技术的多代理协作

本体在多代理系统中起着重要的作用,它提供和定义了一个共享的语义词汇库。然而,在现实的多代理通讯的过程中,两个代理共享完全相同的语义词汇库是几乎不可能的。因为信息不完整以及本体的异构等特性,一个代理只能部分理解另外一个代理所拥有的本体内容,这使得代理间的通讯非常困难。本文就是探索利用近似逼近技术实现基于部分共享分布式本体的多代理通讯,从而实现多代理之间的协作查询。我们使用基于OWLweb本体语言的描述逻辑来描述分布式本体的近似查询技术。最终我们也开发了基于语义近似逼近方法的一个多代理协调查询系统。

Modelling the GSM Handover Protocol in CommUnity

CommUnity is a formal approach to software architecture. It has a precise, yet intuitive mathematical semantics based on category theory. It supports, at the methodological level, a clear separation between computation, coordination, and distribution (including mobility). It provides a simple state-based language for describing component behaviour that is inspired by Unity and Interacting Processes. It also addresses composition as a first class concern and accounts for the emergence of global system properties from interconnections. This paper describes the approach and available tool support by modelling essential aspects of the GSM handover protocol. We also sketch a framework that we are implementing for the distributed execution of such specifications using Klava, a Java library for mobile agent systems based on tuple spaces.     

Method of inequalities-based multiobjective genetic algorithm for optimizing a cart-double-pendulum system

This article presents a multiobjective approach to the design of the controller for the swing-up and handstand control of a general cart-double-pendulum system （CDPS）. The designed controller, which is based on the human-simulated intelligent control （HSIC） method, builds up different control modes to monitor and control the CDPS during four kinetic phases consisting of an initial oscillation phase, a swing-up phase, a posture adjustment phase, and a balance control phase. For the approach, the original method of inequalities-based （MoI） multiobjective genetic algorithm （MMGA） is extended and applied to the case study which uses a set of performance indices that includes the cart displacement over the rail boundary, the number of swings, the settling time, the overshoot of the total energy, and the control effort. The simulation results show good responses of the CDPS with the controllers obtained by the proposed approach.     

Strategies for integrating knowledge-based systems techniques within conventional software environments

This article discusses strategies for integrating knowledge-based systems techniques with conventional computer science techniques. The effect of such an approach has led to the production of an intelligent systems development environment called INDEX. INDEX supports a layered architecture to enable expert system functionality to be generated and integrated at language level, tool level, and system level within a traditional software environment. At the language level, INDEX provides a set of expert system primitives describing low-level operations of an expert system. These primitives can be accessed from most of the conventional languages. At tool level, expert system primitives and relevant INDEX facilities are used in producing expert system tools and various mediation tools for tool integration. At the system level, INDEX can be used to build integrated/coordinated systems. Several applications have been given to demonstrate the effectiveness of our approach, and its future directions. © 1996 John Wiley & Sons, Inc.     

Denotational semantics of communicating processes based on a language for applicative multiprogramming

The denotational semantics of a simple language for describing tightly coupled ‘synchronous’ systems is defined by translating it into a language for applicative multiprogramming. The applicative language has originally been developed for describing nondeterministic stream-processing functions and loosely-coupled systems of communicating processes. Nevertheless, it can be used after very slight generalizations as a semantic target language for defining the meaning of programs representing tightly-coupled, synchronous systems.
