Appearing as follows:
1) Materials are not in good positions and the space is not used wisely.
After being stored, the materials’ location on the record may be different from where they actually are due to some errors.
The departments of stocks, production, and sales cannot fully be in line with the storage management of the raw materials and the production.
In the storehouse, there are raw materials, products and in-made products.
The former one represents the manufacturer to order requested materials, and to take charge of the process of materials’ movement.

The most suitable materials for lining divertor International Thermonuclear Experimental Reactor ITER is considered carbon-graphite materials, and tungsten [2, 3].
Processes materials surface damage when exposed to a plasma stream are determined primarily thermophysical properties of the material, namely, the coefficient of thermal melting and boiling points.
Installation of the beam-plasma discharge has been developed to support the establishment and operation of the Kazakhstan material Tokamak for small-scale testing of materials samples and equipment KTM [5-7].

Keywords: titan alloys, titan boride; fractographic, mechanical properties, welded joint, electron-beam welding.
Materials and Technology Description of experimental samples, electron-beam welding parameters and method of mechanical testing realization are in [4].
Because in case of mechanical testing of welded joints of T1 and T2 alloys the fracture took place in parts of T2 alloy, then, from the one hand, it is the evidence of reaching of more high mechanical characteristic of material of formed welded seam, but, from the another hand, it shows the necessity to fulfill the thermal treatment of the joint obtained in order to ensure the mechanical properties of the materials welded.

All mechanical components of the portable exoskeleton use aluminum alloy as the material, and this modeling use m System of Units, which elastic modulus is 7.2 × 1010Pa, Poisson’s ratio is 0.33 and density is 2700Kg/m3.
To set the appropriate material properties in ANSYS, select the SOLID92 units, and assign the corresponding element attributes for each component in the mechanical structure of portable exoskeleton, and set free grid precision 8, the finite element model can be obtained.
To hide the parts that produce concentrated stress, and only show the residual model results (Table 3), the consequences can be find that stress values are all less than the allowable stress values in working condition 1 and working condition 2, while the stress of thigh, shank, hip and leg hydraulic cylinder all exceed the allowable stress values of the material.

Introduction
Magnetorheological (MR) materials are classified as a function and smart materials due to their rheological properties that can be changed continuously, rapidly and reversibly in the presence of magnetic fields [1].
MR materials classified into several groups such as MR fluid (MRF), MR grease (MRG) and MR elastomer (MRE) [2–4].
Corrosion is degradation of materials which associated with the release of gaseous H2 and it is an inevitable problem resulting in low ductility, brittle and cracking for most of the materials [9].

Take the foundation and soil as the main research object, the soil body ABCD was subjected to the following forces:
Gf was the dead weight of foundation made up of concrete material; Gs was the dead weight of soil body ABCD and it acted on the center of gravity of this soil body;
t was the shear resistance acting on the failure surface depended on the cohesion c, internal friction of soil and assumed failure surface, of which action direction was along failure surface.

Tunneling project like any other project is a one off activity to accomplish the target under the constraints of human, financial, material and other resources.
With the rapid development of science and technology and changes in social environment, the uncertainties involved in the project management are increasing by the day, which brings more and more risks to the project managers, and the loss caused by these risks is getting higher as well.
So it makes the science researchers and project managers become more and more focused on the risk management not only theoretically but also practically [3-5].
