Reliability Analysis of a Three-Engine Simultaneous Pouring Control System Based on Bayesian Networks Combined with FMEA and FTA
Round 1
Reviewer 1 Report
In abstract please mention tangible results.
At the end of section 1 please add research questions and objectives.
Figure 4 has poor quality. Please revise it.
As a separate section please add an independent section, called research steps, for bringing in to whole of research steps. A flowchart is so helpful in this stage.
Although the authors have mentioned FMEA as a tool. RPN calculations have been missed.
In page 7, first paragraph, Z, T,D and R are required more clarification.
In page 8, {z} and so on have been mentioned. What are their difference with Z ...
The authors have declared that figure 9 has been made bu figures 7 and 8. How?
In paper has been declared MAHP has been applied. Please add steps for application of this method in research steps and further provide its results after table 7.
Please add discussion part as an independent section for discussing on the results.
Please add practical implications for generalizing the results in industries.
In section 7, please add recommendations for future researches as well as tangible results.
There are several English writing that should be revised. "Pouring an important process in the production of solid propellant rocket engines, and the cost of solid propellant rocket engine is extremely high. " is ambigous.
"And in reference [18-20], in order to solve the problem of excessive pursuit of relia-bility and waste of resources. a new design optimization model is proposed" Please recheck.

Reviewer 2 Report
Why is the pouring process considered crucial in the production of solid propellant rocket engines, and what are the key factors that make it imperative for this process to have high reliability?
How does the simultaneous pouring of three engines in solid propellant rocket engine production enhance production efficiency, and what are the challenges associated with this approach in terms of complexity and redundancy?
What are the specific characteristics of the multi-state system under consideration, and how do these characteristics complicate the accurate evaluation of system reliability?
Can you elaborate on the proposed reliability analysis method that combines Failure Mode Effect Analysis (FMEA) and Fault Tree Analysis (FTA)? How do these methods work together to assess the system's reliability?
How are the redundant alarm units in the three-engine simultaneously slurry pouring alarm control system taken into account in the reliability analysis, and what role do they play in enhancing system reliability?
Could you provide insights into the process of dividing the control system into redundant states based on alarm function, and how does this division contribute to the reliability evaluation?
How does the Bayesian network method factor into the reliability evaluation and calculation, and what advantages does it offer in this context?
What are the key findings or results regarding the reliabilities of systems with dissimilar redundancy degrees, and how do these findings contribute to the overall understanding of the control system's reliability?
Modified introduction “Analytical investigation of fractional-order Cahn–Hilliard and gardner equations using two novel techniques” “Evaluation of time-fractional Fisher’s equations with the help of analytical methods” “The numerical investigation of a fractional-order multi-dimensional Model of Navier–Stokes equation via novel techniques”
Are there practical implications or recommendations that arise from this reliability analysis method for the design and operation of multi-engine solid propellant rocket systems?
In summary, how does this research address the challenge of ensuring high reliability in complex, multi-state systems like the three-engine simultaneously slurry pouring alarm control system, and what broader applications or implications might it have in the field of reliability engineering?
