  • Applying qualitative reasoning techniques for analysis and evaluation in structural design

    Publication Year: 1991, Page(s):265 - 268
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (308 KB)

    The authors discuss the qualitative reasoning methodologies for analyzing building structures during the preliminary design process. The objective is to build a general tool, an interactive design assistant (IDA) that focuses on the analysis and evaluation aspects of the design process (as opposed to being an automated decision maker). This framework covers a wide variety of situations in the desi... View full abstract»

    In the resource-based paradigm, the interfaces through which technical systems, their components, and their environment interact are modeled as abstract resources, and each technical entity is characterized by the types and amounts of resources it supplies, consumes and uses. This intuitive model, derived in one application area, is shown to be in concordance with the design rationale of modular c... View full abstract»

    Presents an algorithm for finding all solutions of n-ary constraint labeling problems while building constraint networks. The key principle of the algorithm alternating the instantiation of a newly chosen variable, and making the domain values, of already-instantiated variables consistent among them, until all variables are considered. The algorithm chooses variables for domain instantiat... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (948 KB)

    A case study has been constructed in the domain of the configuration of telephone exchanges. These issues are considered by using a special symbolic assignment problem including optimization, which was solved in the course of building a knowledge-based system. It is cast into the usual formalism of constraint satisfaction. A unique feature is the absence of an explicit cost function, requiring the... View full abstract»

    A knowledge-based approach to classification is reported. The proposed methodology uses personal construct theory for interviewing a domain expert to elicit classification knowledge. This interview results in raw data which, on analysis, yields the relationship between different concepts from a user perspective. After finding the relationships, the user is asked to delineate the boundaries which e... View full abstract»

    Describes an extension to deKleer's (1986) assumption-based truth maintenance system (ATMS) that shows promise in making large-scale problem solving more tractable. The approach assumes a problem can be decomposed into a hierarchically related set of subproblems, each of which is represented within its own ATMS partition. It is shown how this decomposition can be used to circumvent the exponential... View full abstract»

    Proposes an architecture for uncertainty reasoning for rule-based systems in Prolog. Previous work has assumed a predefined calculus for the propagation of uncertainty, restricted to a single line of reasoning or where no negation is allowed. The authors identify the issues that need to be considered for both handling negation and taking a more global view. The authors adopt a pragmatic approach a... View full abstract»

    Describes a system to support multiple machine learning strategies applied to the analysis of gene structure in general and the fine-structure of gene regulatory regions in particular. The focus is on two related tasks. The first is to take an overly generalized description of gene structure, represented as a formal grammar, and generate a detailed fine-structure description of a gene family (in t...

    The construction of planning and execution systems for complex real-time operational systems should be based on an understanding of what happens at the time of plan execution, because much of the information to constrain reasoning and decisions is not available prior to execution. The author discusses the results of research on the execution of procedures of a knowledge-rich domain (operation of a... View full abstract»

    A Scene interpretation system that solves the multiplicity problem of scene description is described. To recognize a structured object, the system is required to segment lines or arcs from fragmented image features, and group them into structured parts of the object. The problem is that, in machine vision, the segmentation and grouping processes cannot determine the correct parts of the object uni... View full abstract»

    The methodology used to develop an expert system to predict low clouds is described. The expert system is based on the fundamental physical rules that govern the existence of clouds and is therefore location-independent. The first prototype, built using an expert system shell, confirmed the feasibility of the approach but showed that a much more efficient implementation would be required in order ...
