Reconfiguration of a Bus Chassis Module Using the Digital Expression for Connectivity between Module Interfaces
Round 1
Reviewer 1 Report
There are several questions about the content of the manuscript:
1) Line 180. Criteria for assessing the relationship between modules are proposed. On what basis were these criteria proposed?
2) According to Fig. 9 the chassis under study is symmetrical. Are you need for calculated all the points in Table 1? May be points № 1–5 be enough?
3) Explain the necessity of Figs. 12–14.
4) How does the version of the bus chassis they proposed differ from those proposed earlier in the literature by other researchers?
5) Is there any interest among bus manufacturers in their proposed version of the bus chassis.
6) What is the uniqueness of their proposed engineering solution?

Reviewer 2 Report
This paper researched the reconfiguration of a bus chassis module using the digital expression for connectivity between module interfaces. It is a very interesting study in a relevant area. This paper is well organized. The presentation is satisfactory. Minor revision is suggested for this paper.
Physical hardware reconfigurability is the prerequisite of sustainability. For instance, digital twin-driven rapid reconfiguration of the automated manufacturing system via an open architecture model. The authors may give more discussions and literature reviews.
The “digital expression” idea is similar to the digital twin concept. Digital twin could be used to support the design and control of the physical system. The digital twin-based design is supposed to enable the validating of system performance in a semi-physical simulation manner. The digital twin directly conducts validation and test that can quickly locate the malfunction and inefficiency reason, rule out the mistakes, and test the practicability of physical solution in execution. For instance, digital twins-based smart manufacturing system design in Industry 4.0: a review; digital twin-based designing of the configuration, motion, control, and optimization model of a flow-type smart manufacturing system; digital twins-based remote semi-physical commissioning of flow-type smart manufacturing systems. The authors may give more discussions and literature reviews.
The authors should appropriately compare the performance of proposed methodologies with those found in the published literature.
Please enhance the discussions on the shortcomings or future research directions.
Grammar issues could be addressed before acceptance. Examples of grammar issues:
- “Criteria for judging the compatibility of the connection between bus chassis modules is proposed”
- “Bus chassis modules defined according to their function and position”
- “the layout direction of the structural components are perpendicular”
- “the node network of the two interfaces of the pre-connected module need to fully overlap”
- “the full overlap of the non-adjustable structural components are met”

Round 2
Reviewer 1 Report
If you leave Figs. 12-14 in the text of the manuscript, then it is necessary to describe and explain what the values (numbers) are given in the calculation matrix. These values do not coincide with the coordinates from Tables 1 and 2. Accordingly, it are obtained by calculation. How do the coordinates from the Tables correlate with the values in Figs. 12-14?
