Model Based Approach to Cyber–Physical Systems Status Monitoring
Round 1
Reviewer 1 Report
The authors proposed a model-based approach for solving the task of monitoring the status of complex cyber-physical systems. The topic is interesting, however, modifications and improvements are required. The contributions should be highlighted in the introduction.
Please consider the following comments:
1. I can barely read the abstract, the proofread is a must.
2. Figure 1 needs more justifications.
3. A thorough justification of the selection of the techniques, i.e. Why did you choose such techniques?
4. Consider adding all notations in a table to facilitate it for readers.
5. There are many organizational issues that should be considered, such as, the figures' quality and drawing. Consider redrawing the figures with considering the font size, the involved items, bi-directional arrows and so on.
6. What are the open issues and challenges that needed to be addressed by the researchers in this field?
7. The discussion could also provide future insights and discussions about the assumptions in the paper.
8. More recent works should be adopted instead of some old references, such as:
Ali, Faizan, Moayad Aloqaily, Omar Alfandi and Oznur Ozkasap. “Cyberphysical Blockchain-Enabled Peer-to-Peer Energy Trading.” arXiv: Distributed, Parallel, and Cluster Computing (2020): n. pag.

9. Quantify your conclusion.
10. The results' figures are not clear at all. Please consider redrawing them and add the uncertainties (error bars) to them.

The abstract was modified taking into account comments. The article formulates the problem of receiving actual information about the observed complex cyber-physical systems (CPS). An approach to solving the problem is proposed and its effectiveness is substantiated. |

2. Figure 1 needs more justifications. 4. Consider adding all notations in a table to facilitate it for readers. 5. There are many organizational issues that should be considered, such as, the figures' quality and drawing. Consider redrawing the figures with considering the font size, the involved items, bi-directional arrows and so on. |
All figures are significantly improved taking into account the recommendations. Notations are deciphered in the table. |

In the Section 12 the example of realization presents the results of monitoring systems developed on the basis of the proposed approach for cable television operators. The problem of automatic detection of errors in the operation of user devices was solved. The new systems allow detect 98.5% of all errors occurring in the network. This estimate is based on the number of errors reported by support. Previously used monitoring systems were focused on collecting network data, their ability to detect errors was extremely limited and not used in practice. |

Reviewer 2 Report
The authors have made an overview of different existing solutions, thus having a good overview of the current state in this field.
But the original contribution is not clearly stated. The benefits of the proposed solutions should be better emphasized, and then compared to existing solutions, using the same parameters as reference. It is more relevant to have a quantitative comparison, that currently is not presented.
Figures have poor quality and should be improved.

Round 2
Reviewer 1 Report
The authors have improved the paper, however, more comments also here:
- The title is not properly presented. Don't start with about!
- References needs more attention. For example, Ref. 17 is not correctly cited! Check all references accordingly!
- One more relevant study: Blockchain and Fog Computing for Cyber-Physical Systems: Case of Smart Industry - https://arxiv.org/abs/2005.12834
- Proofread the whole paper.
