An Entropy Model of the Remote Object Monitoring 57_1.pdf

The article deals with the engineering of monitoring of object management systems state. The objects are geographically distant from the center of monitoring that can be an enterprise-monopolist creating products and maintaining through their life cycle. We will understand the term “monitoring” to mean the inspection, analysis, and evaluation processes of the remote object state through observing this process follow-up as well as the research of the trends of the object state changes and the external factors affecting the object [1].
To increase the efficiency of monitoring process, authors propose to implement an entropy approach allowing to examine and control the time for its implementation and the time when telecommunication channel is busy. From the source [2], the entropy is interpreted as a measure of the system uncertainty that can have a different amount of information. The introducing of the entropy evaluation of the request-response pair during a monitoring session allows forming the requestresponse sequence and reduce their length.
To achieve stated objectives, the authors consider the proposed mathematical model of the entropy monitoring process as a directed multi-level graph that is built on the basis of the Markovian chain and that allows to describe the monitoring conditions and the separate stages of the monitoring process. The graph considers the probabilistic characteristics of requests and responses. The main feature of the model is the direction of its practical application. The model is oriented for the analysis of exceptions in which the remote objects can operate. It requires the interactive operation mode of the monitoring system should be provided. The model allows to consider the options of monitoring implementation from the perspective of queueing systems as well as within closed local area networks.

Software Maintenance and Operational Reliability Evaluation on the Basis of Network-centric Architecture 000_3.pdf

The article deals with the approach to the creation of network-centric control system of condition of products produced by the original equipment manufacturer and operated on the distant sites. The organization of interaction between the center (manufacturer) and the consumer that serves as the basis for the creation of network-centric structure is proposed. The ability of high-quality control of events on sites is shown by giving an example of remote control of failures and operating products troubles. This leads to the increasing of the product operation efficiency and gives an opportunity for developers to upgrade products faster due to the fast feedback. The structure, the architecture, the general algorithm of functioning, and the description of general mathematical model of software product maintenance and functioning reliability evaluation system are considered. The proposed solutions are implemented as a software package that was used for computing experiment and the confirmation of the discussed approach practical application.
