Here, identified performance indicators for materials management are presented.
It shows the value of unused materials that need to be returned or restocked.
This follows from conventional materials management being carried out using bill-of-materials, inventory data and master production schedules to determine time-phased plans for components and raw materials required for production [24].

Many structural metals possess dynamic fracture and fragmentation properties of materials that differ appreciably from their static counterparts.
Analysis of the dynamic behavior of materials, several kinds of tests such as tension, compression or shear may be used.
Lateral efficiency loading can be widely used in the specimen ring on a variety of sizes and materials without limitation.

Synthesis and Characterization of Double Pore Size Multiphase Materials from Waste Aluminum Slag and Activated Carbon Yanqing Chen a, Renping Wu b College of Materials Science and Engineering, Fuzhou University, Fuzhou 350108, China a cyq_20050603@126.com, b wurenping@fzu.edu.cn Keywords: Waste aluminum slag; Activated carbon; Double pore size; Multiphase materials Abstract.
A new type of double pore size activated alumina/activated carbon multiphase material was made by using waste aluminum slag and activated carbon as main raw materials.
Table 2 lists the iodine adsorption values of three materials.
Clearly the benzene adsorption capability of the new material is superior to that of pure activated alumina or activated carbon materials.
Furthermore, the benzene adsorption effect of multiphase materials is excellent.
