A survey on methods of timing parameters' probabilistic evaluation in distributed control systems: High-fidelity model of LonWorks-based network

Abstract

The article describes state-of-the-art models and methods to estimate probabilistic and temporal characteristics of distributed control systems (DCS), based on industrial real-time networks, or fleldbuses. Conducted review and synthesis of recent publications shows the lack of information about using of integral criteria for DCS performance evaluation. Being implemented at the example of LonWorks technology, proposed approach allowed identifying previously undescribed system parameters relationship, which helped to develop new analytical and simulation models, yielding more accurate estimates of functioning quality parameters of such systems. It is worth to note that the area of effect for proposed approach isn't limited by only industrial control networks like LonWorks or other fieldbus systems, but it also can be used for the wide class of a wired and wireless CSMA-based network.
