| description | The article is devoted to the formalization of the problem of distribution of target information flows during the operation of the ERS space system. It is proposed to consider the system as a complex, geographically-distributed information system, the main task of which is to implement a full service cycle, starting with the formation of an application and ending with the provision of a finished thematic product. The decomposition of the ERS space system as a complex information organizational and technical system was carried out, the system and consumer characteristics of its elements were determined. The possibility is substantiated to carry out an objective curtailment of system performance indicators and go to two particular ones that characterize the effectiveness of the target functioning of the system as a whole: the promptness (time) of fulfilling consumer requests for a finished thematic product and the cost of the finished thematic product. A general methodological approach to solving the technical problem is proposed. The result is a formal presentation of the task of distributing the streams of target information during the operation of the ERS space system as a sequence of the following operations: formation of an application; determination of the list of requests to the system required to complete the application; determining the processes and the sequence of their execution that will process the corresponding requests; optimization of the time distribution of processes among the elements of the system, taking into account the selected performance indicators and existing limitations. |
