20130268809 | METHOD, SYSTEM, AND COMPUTER PROGRAM FOR SYSTEM DIAGNOSIS DETECTION - The present invention is directed to a method, system, and computer software for obtaining system diagnosis, comprising describing a diagnosis domain comprising a plurality of possible diagnoses, prioritizing the plurality of possible diagnoses based on at least one of a plurality of confidence levels, a preference function, and a calculation of a relationship between a plurality of confirmed system symptoms and a plurality of possible diagnoses, generating a plurality of hypotheses for incipient system symptoms, selecting a hypothesis from the generated plurality of hypotheses, obtaining information regarding a plurality of system observations, and obtaining a selection relevant diagnostics for the system. | 10-10-2013 |
20140277755 | CONTROL OF A MACHINE - A method and apparatus for actuating a machine is provided in which a relaxed abduction problem is determined in order to explain the greatest possible part of the observations with the fewest possible assumptions. Based upon two preference orders over a subset of observations and a subset of assumptions, tuples are determined so that the theory together with the subset of assumptions explains the subset of observations. On the basis of the formal validity of the approach certain characteristics of the set of results (such as correctness, completeness, etc.) are checked. By the choice of underlying representational language and the preference relations, the complexity of the problem-solving process is influenced and thus flexibly adapted with regard to domain requirements. The invention may be used for any machines, e.g. gas turbines or steam turbines. | 09-18-2014 |
20140297578 | PROCESSING A TECHNICAL SYSTEM - A method for processing a technical system is provided to predict a technical system's state and/or to provide a diagnosis of the technical system or at least one of its components. The prediction is determined based on a model-based complex event processing (CEP) approach using declarative models. This facilitates considering complex information sources as input data and allows providing a diagnosis based on diagnostic models, wherein the models can be interpreted and/or changed even by users who are not programmers. In addition, time and/or temporal relations can be modeled and considered and an open world assumption can be incorporated to allow more valuable assessments of diagnoses. The invention is applicable for all kinds of technical systems, e.g., industry and automation systems comprising in particular rotating devices and/or generators. | 10-02-2014 |
20140358865 | PROCESSING A TECHNICAL SYSTEM - Rules of a rule base are transformed in an automated fashion in order to be able to conduct consistency checks and generate explanations and thus classify and correct existing rules. This is beneficial in particular in large systems with existing rule bases, e.g., wherein each rule is associated with at least a diagnostic task of a component of a technical system, e.g., a power system. The task can be subject to fault detection, fault isolation, predictive diagnosis or reporting. The solution presented provides an overview of large sets of rules and thus allows determining which rules are suitable and which are not. The invention is applicable for all kinds of technical systems, e.g., industry and automation systems, in particular power systems. | 12-04-2014 |
20150039610 | METHOD AND SYSTEM FOR A DATA ACCESS BASED ON DOMAIN MODELS - A system, a method and a computer product are disclosed. The method includes using at least one domain ontology including a plurality of domain models connected through mappings to a plurality of data sources, the data sources storing data to be accessed by the query; receiving a query by a query formulation unit; evaluating at least one of a language for defining at least one of the domain models involved in the query, a language of mappings involved in the query and a language of the query and selecting a query answering mode in accordance with results of the evaluation and retrieving an answer meeting at least one query condition from the data sources. | 02-05-2015 |
20150178353 | PROCESSING AN INPUT QUERY - An embodiment relates to a method for processing an input query comprising: building an event processing framework based on the input query by converting operators of the input query into building blocks of the event processing framework. | 06-25-2015 |
20150261825 | Determination of the Suitability of a Resource - According to the invention, a resource, which could optionally be used for a maintenance task of a technical system, is taken into consideration and the possible use thereof is checked even if not all conditions that would be required as per a model description of the resource are met. Thus, a compromise for a resource that comes closest to the sought resource, i.e. is as suitable as possible, can be found in an automated and efficient manner. The invention can be used, for example, for maintenance tasks of large and complex technical systems, for example, in automation technology or production technology. | 09-17-2015 |
