The advantage and innovation of linear rail space dynamic scheduling technology has three parts: (1) A uniform scheduling handling framework is established, taking complete assembly, priority, delivery date, site resource utilization, and the adjacent rail constraints in rocket assembly into consideration; (2) Establish heuristic scheduling rules which can be adapted in the rocket assembly scheduling, such as scheduling resource constraints, priorities, and complete assembly control, proximity arrangement; (3) Summary various disturbances in the production process and send them into four categories:  the task layer, the production process layer, the material resources layer and production execution layer.

The resulting solid materials were washed with ultra pure water and ethanol, and freeze-dried.
The shape of the solid materials was observed using a scanning electron microscope (SEM).
The porosity of the solid materials was calculated using stereology and their density measured in a pycnometer.
Figure 2 shows SEM photographs of solid materials before and after heat treatment at 1300 °C.
Figure 3 shows SEM photographs of the heat-treated solid materials seen in Fig. 2, but sieved into a narrow size range of 25 ± 5 µm.

The cutting force is low while cutting the softened material because of the suitably high cutting temperature.
It is noticed that a number of continuous chips happen at the higher cutting speed due to the higher cutting temperature which leads to the softening material.

Temperature and strain rate effects on PMMA under quasi-static and moderate strain rate were analyzed by Arruda [2] and material property characterization was also carried by Lee [3] under dynamic loading, they found that the increase of temperature has a drastic effect on the stress-strain behavior and thermal softening was observed for the tested materials.
It is found that temperature effect on material property is remarkable.

The attempt is to validate the applicability and reliability of the method for this composite material when the masonry materials’ texture is exploited as the reference pattern to monitor geometry variations of the specimen under increased load levels.
The different behaviour of the two masonry constituent materials under compression is clearly visible with the mortar joints appearing more compressible than the bricks.
