Therefore, AGV configuration directly affects the productivity and cost of production systems.
It is determined by the transport task needs and dynamic characteristics, and it affects the scheduling system and the dynamic characteristics.
Constrained by scheduling rules and walking routes and other factors, the additional AGV may not have much impact on the transport time.
In the table, we define material attribute as .MUs.p1, quantity as 1 and properties as t.
We define the entity type as T1, MU attribute name as custAttr (AT1 value of this property).

The other factors that greatly affect the selection of building materials are
· thermal comfort,
· good mechanical properties (strength and durability),
· aesthetic characteristics and
· ability to construct quickly.
However, it is also important for sustainable development to consider social and economic factors as well.
· Concrete is a durable material with excellent mechanical properties.
The use of admixtures—materials added to concrete—becomes very popular as the final composite can have better durability and gains some specific unique properties.
HPC is a type of concrete that has a low water- cement ratio, properties of which are improved by the use of super-plasticizers

Introduction
Changing the deformation and annealing parameters affects many structure sensitive material
properties like the electrical, mechanical and magnetic properties.
Cold rolling is often the final step of the entire rolling process, where the final thickness is obtained and which generates the greatest impact on the final properties of the sheet.
The question that will be investigated is whether or not the rolling reduction will affect the prevailing recrystallization mechanism.
These spreads are independent of the Taylor factors of the grains and therefore appear to be determined by the requirements of strain compatibility near grain boundaries and not by the crystallographic orientation of the grain. [14, 15] After a rolling reduction of 60%, the strain heterogeneities of the deformed microstructure were much better developed.
Here, it was found, by contrast, that the nucleation stage of secondary recrystallization in ULC steel has very specific and important properties.

Properties, Environmental Impact and Adaptability of Insulation Materials
Building insulation materials are evaluated based on key properties that affect their performance and suitability for different applications (Table 1) [14].
Insulation materials are crucial for managing indoor comfort and safety, with key factors including hygroscopic properties, acoustic performance, and fire resistance.

The catalytic performance was found to be strongly affected by thermal treatment of the prepared catalyst prior to the reaction.
The preparation of gold-based catalysts has been widely studied [2-6] and the most significant catalytic properties of gold supported catalysts have been achieved for CO oxidation reaction at ambient temperature [4-7].
The dimensions of gold particles, support material, synthesis method, parameters for the preparation and the catalyst activation procedures are major factors to augment the catalytic activity [7-11].
As-synthesized resulting Au/TiO2 catalysts were characterized using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and Raman Spectroscopy for measuring various properties (phase, structure etc).
In either case, the Au is clearly highly dispersed though the titania matrix, which should maximize its effect on the surface properties of the support material.

Jin et al. [24–26] demonstrated the existence of whispering gallery modes (WGMs) in the hollow-pillar PMs, and numerically studied their multiplexing properties.
Therefore, it is conceivable that the WGMs in PMs may be affected by rotation.
We now turn our attention to considering the band structure of such periodically arranged local resonance units, along with the implications of rotation on their properties.
And the imaginary part of is referred to as the attenuation constant, which characterizes the attenuation properties of the elastic wave propagation.

The shape of these nanoparticles aggregates are of great significance for the mechanical material properties and in consequence, knowing the percentage of aggregates of each shape within of a specific group of shapes can give an idea of the final properties of the material.
Introduction The final application of materials, like the study case of rubber blends but applicable to many materials, is strongly dependent on their properties and on the reinforcement particles that constitute the material.

Nowadays there has been extensive suture material and suture for surgeons to choose, and for a special operation suture selection, according to the physical and biochemical properties of sutures and wound healing properties were determined.
Absorbable suture material properties Suture line of previous classification methods usually can be divided into the material of natural materials, synthetic materials and metal materials or according to the structure and machining process is divided into a monofilament, braided and twisting type.
Many scholars think these problems have do with suture techniques, poor quality, too much line knot, needle, tendon destruction of blood supply and other factors.
These increase the healing condition, reduce tendon adhesion factor.
And it can be quickly absorbed properties and good biocompatibility, can avoid the adverse inflammatory rejection and the second damage non absorbable suture to the affected body when takes the line.
