Integrate information consumer need based on information and accuracy modeling with time consideration

This paper presents a temporal information modeling and describes its use in the context of intelligent instruments. First, we propose an information modeling for the use of measurement information that takes into account the response time. This model offers the advantage of computing the uncertainty associated with the information. Information can be obtained from several sources. From the proposed model, the uncertainty associated with information comming from each source is computable at any time. We present a structure that makes it possible to use the knowledge of a consumer needs in order to obtain the best quality of required information.
