R1: a rule-based configurer of computer systems
TL;DR: R1 is a program that configures VAX-11/780 computer systems and uses Match as its principal problem solving method; it has sufficient knowledge of the configuration domain and of the peculiarities of the various configuration constraints that at each step in the configuration process, it simply recognizes what to do.

TL;DR: There is a genuine need to develop and evaluate model-based systems in an industrial context to determine whether their potential benefits can be realised in practice.
Abstract: This paper describes the research undertaken to determine the impact that model-based approaches to fault diagnosis have made in the industrial environment. To verify the hypothesis that few if any model-based approaches were finding practical applications, an investigation was conducted. The results of the investigation indicated that whilst most systems had been applied to genuine, rather than hypothetical, devices only one system had been implemented in the workplace. Furthermore, this paper identifies some of the reasons for the lack of practical applications of the model-based approach. The reasons for the successful industrial implementation of one model-based diagnostic system (MIDAS) are presented. Finally, it is concluded that there is a genuine need to develop and evaluate model-based systems in an industrial context to determine whether their potential benefits can be realised in practice.

TL;DR: Development of an Expert Systems course for electronics students in 1991, ‘Electronic Design with Expert Systems’ was specifically created for Electronic Engineering students.
Abstract: Development of an Expert Systems course for electronics studentsIn 1986, ‘Expert Systems’ was first offered to Computing and Information Systems students. Over time, Business, Management, and Engineering students elected to take this subject. In 1991, ‘Electronic Design with Expert Systems’ was specifically created for Electronic Engineering students. The evolution of both subjects and the lessons learned are discussed.

TL;DR: A CLP-based reasoning engine that is developed for a commercial configuration system and devoted to the key issues of constraint propagation and optimization as well as to the relevant process of assignment revision is described.
Abstract: Product configuration systems are an emerging software technology that supports companies in deploying mass customization strategies. In this paper, we describe a CLP-based reasoning engine that we developed for a commercial configuration system. We first illustrate the advantages of the CLP approach to product configuration over other ones. Then, we describe the actual encoding of the considered product configuration problem as a constraint satisfaction problem. We devote a special attention to the key issues of constraint propagation and optimization as well as to the relevant process of assignment revision. A comparison with existing systems for product configuration concludes the paper.

22 Aug 1977TL;DR: Some of the issues that bear on the design of production system languages are explored and the adequacy of OPS is tried to show for its intended purpose.
Abstract: It has been claimed that production systems have several advantages over other representational schemes. These include the potential for general self-augmentation (i.e., learning of new behavior) and the ability to function in complex environments. The production system language, OPS, was implemented to test these claims. In this paper we explore some of the issues that bear on the design of production system languages and try to show the adequacy of OPS for its intended purpose.

TL;DR: In this article, the authors explore the role of conflict resolution in providing support for production systems designed to function and grow in environments that make large numbers of different, sometimes competing, and sometimes unexpected demands.
Abstract: Production systems designed to function and grow in environments that make large numbers of different, sometimes competing, and sometimes unexpected demands require support from their interpreters that is qualitatively different from the support required by systems that can be carefully hand crafted to function in constrained environments. In this chapter we explore the role of conflict resolution in providing such support Using criteria developed here, we evaluate both individual conflict resolution rules and strategies that make use of several rules.
