The system being developed is designed to interface with some existing automatic test equipment. Results of tests from this test equipment are the main input to the expert system. Another input is information about signals at various points in the circuit under test. This information is supplied by the user. Both deep and shallow knowledge are used in the diagnostic process. The system is developed in KEE from Intellicorp so the main knowledge representations are rules and frames. The deep knowledge in the system is represented loosely as qualitative reasoning as this is considered to be the way that technicians reason about the causal interactions in a circuit.","doi":null,"url":"https://ijcai.org/proceedings/1987/87","pdf":"https://ijcai.org/proceedings/1987/0087.pdf","markdown":"https://ijcai.org/proceedings/1987/87.md","bibtex":"https://ijcai.org/proceedings/1987/bibtex/87","volume":{"slug":"1987","title":"Proceedings of the Tenth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1987","url":"https://ijcai.org/proceedings/1987/","year":1987,"location":"Milan, Italy","dates":"","editors":"John McDermott","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":"Knowledge Representation","track":"Knowledge Representation","number":87,"pages":{"first":443,"last":444},"keywords":[],"videos":[],"references":[{"position":1,"raw":"Cunningham P. et al., \"Diagnostic Heuristics and Perspectives\", Expert Systems -'86, pp242-253, 1986.","title":"Diagnostic Heuristics and Perspectives","authors":"P Cunningham","year":"1986","venue":"Expert Systems","doi":null,"url":null,"internal_url":null},{"position":2,"raw":"Davis R., Shrobe H., et al. \"Diagnosis Based on Description of Structure and Function\", AAAI-'82, pp 137-142, 1982.","title":"Diagnosis Based on Description of Structure and Function","authors":"R Davis, H Shrobe","year":"1982","venue":"AAAI-'82","doi":null,"url":null,"internal_url":null},{"position":3,"raw":"Davis R. \"Diagnostic Reasoning Based on Structure and Behavior\", Artificial Intellieence, Vol.24, (1984) pp347-410, 1984.","title":"Diagnostic Reasoning Based on Structure and Behavior","authors":"R Davis","year":"1984","venue":"Artificial Intellieence","doi":null,"url":null,"internal_url":null},{"position":4,"raw":"Genesereth M.R. \"Diagnosis Using Hierarchical Design Models\", AAAI-'82, pp 278-283, 1982.","title":"Diagnosis Using Hierarchical Design Models","authors":"M R Genesereth","year":"1982","venue":"AAAI-'82","doi":null,"url":null,"internal_url":null},{"position":5,"raw":"Genereseth M.R. \"The Use of Design Descriptions in Automated Diagnosis\" , Artificial lntellieence, Vol.24, (1984) pp 411-436, 1984.","title":"The Use of Design Descriptions in Automated Diagnosis","authors":"M R Genereseth","year":"1984","venue":"Artificial lntellieence","doi":null,"url":null,"internal_url":null},{"position":6,"raw":"de Kleer J., Brown J.S., \" The Origin, Form and Logic of Qualitative Physical Laws\", IJCAI-'83 , pp1158-1169, 1983.","title":"The Origin, Form and Logic of Qualitative Physical Laws","authors":"J De Kleer, J S Brown","year":"1983","venue":"IJCAI-'83","doi":null,"url":null,"internal_url":"/proceedings/1983/267"},{"position":7,"raw":"Forbus K., \"Qualitative Reasoning about Physical Processes\", IJCAI-'81, pp326-330, 1981.","title":"Qualitative Reasoning about Physical Processes","authors":"K Forbus","year":"1981","venue":"IJCAI-'81","doi":null,"url":null,"internal_url":"/proceedings/1981/64"},{"position":8,"raw":"Kuipers B., \"Qualitative Simulation\", Artificial Intemeence, Vol.29, No.3, pp289-338, 1986.","title":"Qualitative Simulation","authors":"B Kuipers","year":"1986","venue":"Artificial Intemeence","doi":null,"url":null,"internal_url":null},{"position":9,"raw":"Rupra K., \"Switching Mode Power Supplies\", in Power Transistor and TIL Inteerated Circuit Applications, ed.","title":"Switching Mode Power Supplies","authors":"K Rupra","year":null,"venue":"Power Transistor and TIL Inteerated Circuit Applications","doi":null,"url":null,"internal_url":null},{"position":10,"raw":"Bryan Norris, Me Graw Hill, 1977.","title":null,"authors":"Bryan Norris, Graw Me, Hill","year":"1977","venue":null,"doi":null,"url":null,"internal_url":null},{"position":11,"raw":"Moszkowski B., \"A Temporal Logic for Multi-Level Reasoning About Hardware\", Computer, Vol.18, No. 2, ppl0-19, 1985.","title":"A Temporal Logic for Multi-Level Reasoning About Hardware","authors":"B Moszkowski","year":"1985","venue":"Computer","doi":null,"url":null,"internal_url":null},{"position":12,"raw":"Hayes P.J., \"The Na'ive Physics Manifesto\" in Expert Systems in the Microelectronics Aee. ed.
