Science assessment to air material suppliers is an effective measure that insures cost controlling and safety operating of an airline.
In this paper, combined with the actual situation of air materials suppliers, established assessment indicator system of selection air material suppliers, according to the fuzziness of assessment indicators of air material suppliers, the fuzzy comprehensive assessment theory is introduced to assess air material suppliers.
The fuzzy comprehensive assessment theory is applied to the assessment of air material suppliers to establish a comprehensive assessment based on fuzzy mathematical assessment of air material suppliers and aircraft materials applied to a vendor assessment.
Introduce the fuzzy comprehensive assessment method of the assessment of air materials suppliers, for the condition of air material suppliers assessment provides a new way of thinking.

Otherwise, the proposed design criteria conserve the material value systematically which make the post use materials of plastic packaging more financially feasible as raw materials in plastic recycling industry.
Methodology MVC should not be confused to Material Conservation (MC) which protects the materials such as in painting or archive, and archaeological artefact materials.
Assessment of the quality and value of plastic waste as raw materials.
As an empirical evident, clean plastic packaging waste materials was valued 40% to 50% more expensive than the selling price of dirty materials [17].

Medical building materials of structural properties and electromagnetic interference shielding in the quartz crystal plane coated Ni based thin film Fei-Shuo Hung Department of Travel Industry Management, Far East University, Tainan, Taiwan, China Keywords: Electromagnetic interference (EMI), Ni, Medical building materials Abstract.
Medical use quartz components for electromagnetic shielding materials research topics very rarely, therefore, intend to systematic development of coated quartz glass materials.
So, the application data for the characteristics of interface layer and anti-electromagnetic (EMI) properties are obtained. building materials extended to the health care system materials systems.
