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 this paper, the authors describe recent progress in extending chunking to be a general learning mechanism by implementing it within a general problem solver, using the Soar problem-solving architecture.
Abstract: Chunks have long been proposed as a basic organizational unit for human memory. More recently chunks have been used to model human learning on simple perceptual-motor skills. In this paper we describe recent progress in extending chunking to be a general learning mechanism by implementing it within a general problem solver. Using the Soar problem-solving architecture, we take significant steps toward a general problem solver that can learn about all aspects of its behavior. We demonstrate chunking in Soar on three tasks: the Eight Puzzle, Tic-Tat-Toe, and a part of the RI computer-configuration task. Not only is there improvement with practice, but chunking also produces significant transfer of learned behavior, and strategy acquisition.

TL;DR: An uncertain product configuration model based on uncertain lead-time and time-sensitive demand using uncertain programming is developed and it is found that the profit and the sourcing strategies are sensitive to the uncertainty and the outsourcing strategy helps companies reduce losses due to uncertainty.
Abstract: Product configuration is widely practiced and is very effective when offering mass customisation production. This strategy assists manufacturers in understanding customers' preferences and demands,...

TL;DR: The Conceptual Analysis and Review Environment (CARE) as mentioned in this paper is a tool for conceptual graph-based decision support for accountants in strategic planning, which can help accountants apply their skills in the direction of strategic management problems.
Abstract: The hypothesis of the research is "conceptual graphs are a suitable knowledge-base decision
support tool for use by managemenat ccountants in strategic planning", explained as follows.
Knowledge-based approaches can help accountants apply their skills in the direction of
strategic management problems. Such problem domains cannot be modelled effectively by
computer alone, hence we are only interested in those advanced knowledge-based
methodologies that can be adequately reviewed by strategic management accountants in the
light of their own continually changing tacit and implicit knowledge.
Structured diagram techniques, such as flowcharting, are well known by accountants and are a
clearly understandable yet important aid in problem review. Apart from being founded on a
logically complete reasoning system, the knowledge-based methodology of conceptual graphs
was formulated to be an enhancement of these other methods. Furthermore the graphical form
of conceptual graphs enjoy an apparent similarity to the 'negating' brackets in the accountant's
traditional bookkeeping model.
After conducting a comparative study with two similar methodologies in current use showing
the technical advantages of conceptual graphs, the Conceptual Analysis and Review
Environment computer software was devised and implemented. CARE was used to test the
- accepted graphical form of conceptual graphs through a series of user evaluation sessions. The
evaluations started out with subjects from the conceptual graphs community itself, then key
business school staff, and culminated in a session with senior practising accountants. In
addition, CARE was enhanced iteratively in accordance with the results of each evaluation
session.
Despite their strong prima facie attractiveness and positive response from the conceptual
graphs community session, as the user evaluations progressed it became increasingly evident
that the inherent complexity of conceptual graphs fundamentally undern-tined them as a viable
tool, other than for very trivial problems well below the level needed to be viable for strategic
management accountancy. Therefore the original contribution of this research is that its
hypothesis turns out to be false.

TL;DR: It is shown, on the basis of the experience in the field, that a richer model is needed to capture the specificity of a configurable product and other functionalities to easily handle the resolution process.
Abstract: To increase market shares, industry needs to provide customized products, at a low price and low delivery time. But establishing a valid configuration is a complex, timeconsuming and costly task. There is a need for software tools to help people to model their products, and allow them to compute a valid configuration. The CSP framework seems to be a valuable candidate to express models for configurable product and to solve the configuration problem. In this paper, we will show, on the basis of our experience in the field, that we need a richer model to capture the specificity of a configurable product and other functionalities to easily handle the resolution process. We will review some previous work fulfilling some of these functionalities and finally present an approach able to handle the whole problem.

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.
