Dear Dr. Mizuno,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

Please submit your revised manuscript by Jul 12 2024 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org. When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

Please include the following items when submitting your revised manuscript:

• A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). You should upload this letter as a separate file labeled 'Response to Reviewers'.
• A marked-up copy of your manuscript that highlights changes made to the original version. You should upload this as a separate file labeled 'Revised Manuscript with Track Changes'.
• An unmarked version of your revised paper without tracked changes. You should upload this as a separate file labeled 'Manuscript'.

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter. Guidelines for resubmitting your figure files are available below the reviewer comments at the end of this letter.

If applicable, we recommend that you deposit your laboratory protocols in protocols.io to enhance the reproducibility of your results. Protocols.io assigns your protocol its own identifier (DOI) so that it can be cited independently in the future. For instructions see: https://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols. Additionally, PLOS ONE offers an option for publishing peer-reviewed Lab Protocol articles, which describe protocols hosted on protocols.io. Read more information on sharing protocols at https://plos.org/protocols?utm_medium=editorial-email&utm_source=authorletters&utm_campaign=protocols.

We look forward to receiving your revised manuscript.

Reviewer's Responses to Questions

Comments to the Author

1. Is the manuscript technically sound, and do the data support the conclusions?

The manuscript must describe a technically sound piece of scientific research with data that supports the conclusions. Experiments must have been conducted rigorously, with appropriate controls, replication, and sample sizes. The conclusions must be drawn appropriately based on the data presented.

Reviewer #1: Partly

Reviewer #2: Yes

3. Have the authors made all data underlying the findings in their manuscript fully available?

The PLOS Data policy requires authors to make all data underlying the findings described in their manuscript fully available without restriction, with rare exception (please refer to the Data Availability Statement in the manuscript PDF file). The data should be provided as part of the manuscript or its supporting information, or deposited to a public repository. For example, in addition to summary statistics, the data points behind means, medians and variance measures should be available. If there are restrictions on publicly sharing data—e.g. participant privacy or use of data from a third party—those must be specified.

Reviewer #1: Yes

Reviewer #2: Yes

Reviewer #1: This paper is applied a closed BCMP queueing network to a real-world model and examining the limitations of the theoretical solution, The paper needs some improvements as listed below.

1. The abstract needs to be a little bit more precise and numerically conclusive.

2. Introduction can be more impressive in terms of Identifying the Research Problem or Gap, State the Research Objectives, Outline the Scope and Methodology, Highlight the Significance of the Study and Provide an Overview of the Paper Structure,

so, author should rewrite the introduction.

3. Related work should be biased on latest work and they should cite the latest research papers too.

4. In this paper, the author provided a theoretical and practical comparison of the results, whether the author should compare their results with the other (same area) paper’s results because in research papers we are working to improve the already done work and result.

5. Overall, an English translation is grammatically sound but the order of placement of topics often goes wrong and reading patterns get out of hand.

6. Since the author did not cite any sources for equations No. 1 through No. 9, it is unclear how real and true they are.

7. Working steps (algorithm) is missing.

8. Include Flow chart and symbol table with this work.

9. Overall, an English translation is grammatically sound but the order of placement of topics often goes wrong and reading patterns get out of hand.

Reviewer #2: This present paper talks about the parallelization and simulation of MVA to BCMP, the traditionally used and a representative model of a closed queueing network. This work is interesting, however it has few lacks that need to be fixed.

- The introduction lacks of references.(from lines 53 to 60)

- The font size in table 1 need to adjusted in such away that the table can be readable easily.

- The ralated work section, is not up to date, please update it. The last reference you are using is since 2019 and there have been few works since then related to the closed BCMP queueing network.

- It would also interesting that the authors add a flow chart of the process of their proposed approach on the system solved used.

- Figures 1, 2 and 3 are not placed correctly in the paper.

- The presented results are promising, however, for a better fainess of the study, the authors are requested to do a comparison study to state of the art with other approaches (if there exist few) for the same datasets in order to show the performance quality of the proposed algorithm.
