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.
About: This article is published in Artificial Intelligence.The article was published on 1982-09-01. It has received 1001 citations till now. The article focuses on the topics: Configuration Management (ITSM) & Knowledge-based configuration.

TL;DR: In configuration design parts are selected and connected to meet customer specifications and engineering and physical constraints that arise from exogenous concerns, such as the available parts, the way parts can interact, and the manufacturing plant.
Abstract: In configuration design parts are selected and connected to meet customer specifications and engineering and physical constraints. Specifications include preferences (e.g., “prefer lower cost to higher performance, all things being equal”), bounds on various resources (e.g., “the computer should have four PCI slots”), and other information to customize a configuration. Constraints typically arise from exogenous concerns, such as the available parts, the way parts can interact, and the manufacturing plant.

TL;DR: The authors describe TOPAS (trunk operations, provisioning, and administration system)-ES, an expert system that diagnoses transmission and signaling problems arising on telephone trunks in the AT&T long-distance network.
Abstract: The authors describe TOPAS (trunk operations, provisioning, and administration system)-ES, an expert system that diagnoses transmission and signaling problems arising on telephone trunks in the AT&T long-distance network. It runs autonomously, issuing operations system commands to retrieve trouble reports and perform measurements on the problematic trunks. It is also a distributed system, since different copies of TOPAS-ES must communicate with one another in order to coordinate the diagnosis process from both ends of a trunk. The three software subsystems of TOPAS-ES are described in detail, namely, the inference subsystem, the communications subsystem, and the graphical end-user interface. >

TL;DR: A prototype expert system, the Expert Session Planner (ESP), is presented, which is designed to support GDSS session facilitators during critical pre-session planning and offers a foundation upon which to build further intelligent support software for group meeting processes.
Abstract: The authors present a prototype expert system, the Expert Session Planner (ESP), which is designed to support GDSS (group decision support systems) session facilitators during critical pre-session planning. Its major components are a group selection module, a calendar scheduling module, and a tool selection module. ESP's advantages are that it allows scarce human facilitator knowledge to be distributed and provides consistency across sessions, provides training for novice session facilitators in the selection of GDSS software, and offers a foundation upon which to build further intelligent support software for group meeting processes. A case study illustrates the use of the expert system for planning a typical group meeting. >

TL;DR: In this paper, the ICMAUS framework was introduced to model probabilistic reasoning as information compression by multiple alignment, uniflcation, and search (ICMAUS).
Abstract: This article introduces the idea that probabilistic reasoning (PR) may be understood as information compression by multiple alignment, uniflcation and search (ICMAUS). In this context, multiple alignment has a meaning which is similar to but distinct from its meaning in bioinformatics, while uniflcation means a simple merging of matching patterns, a meaning which is related to but simpler than the meaning of that term in logic. A software model, SP61, has been developed for the discovery and formation of ‘good’ multiple alignments, evaluated in terms of information compression. The model is described in outline. Using examples from the SP61 model, this article describes in outline how the ICMAUS framework can model various kinds of PR including: PR in best-match pattern recognition and information retrieval; one-step ‘deductive’ and ‘abductive’ PR; inheritance of attributes in a class hierarchy; chains of reasoning (probabilistic decision networks and decision trees, and PR with ‘rules’); geometric analogy problems; nonmonotonic reasoning and reasoning with default values; modelling the function of a Bayesian network.

TL;DR: In this paper, the authors present weltweit zahlreiche erfolgreiche Anwendungen, e.g., DEX, MYCIN, DEX.C3, R1 bzw. XCON.
Abstract: Wissensbasierte Systeme besitzen seit jeher eine relativ grose Bedeutung im Rahmen des Forschungsgebietes der Kunstlichen Intelligenz, besonders im Hinblick auf Anwendungen und den konkreten Einsatz in der Praxis. Insbesondere die beruhmt gewordenen Diagnosesysteme (Puppe 1986) wie das in Stanford von Buchanan und Shortliffe entwickelte System MYCIN zur Diagnose-und Behandlungsunterstutzung bei Menengitis und bakteriellen Infekten (Buchanan/Shortliffe 1984) oder das System DEX.C3 zur Fehlerdiagnose in automatischen Getrieben bei Ford (Henne/Klar/Wittur 1985), und Konfigurationssysteme wie das System R1 bzw. XCON von Digital Equipment (McDermott 1982) haben hierzu beigetragen. Inzwischen existieren weltweit zahlreiche erfolgreiche Anwendungen.

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.
