Mass Customization produ ct manufacturing is aimed at the objection of agile responding to customer deman d, market changing and market opportunities to combine with modern management te chnology and advanced manufacture technology, and to use the development model o f design for product family and technology concurrent. Therefore, in the environ ment of market continuing to change with a high speed, MC enterprise is required to raise its ability of controlling future market by improving its "agility of product manufacturing". So it is necessary to research about the question of agi lity evaluation of MC product manufacturing. Base on the characteristics of the Mass Customization (MC) product manufacturing and the requirement of the agile m anufacturing, this paper establish an MC product manufacturing Agility evaluatio n index system through studying MC enterprise’s organization management agility evaluation and MC products design agility evaluation and MC manufacture agility evaluation. Also, with Xi Dian Casting limited company as an example, the multi -grade fuzzy assessment method is used to evaluate its agility.展开更多

The differential scanning calorimetry （DSC）, X-ray diffraction （XRD）, scanning electron microscopy （SEM） and complex impedance techniques were employed to characterize the samples. The experimental results indicated that the capability of glass forming in this system is superior to that of L20-A1203-TiO2-PzO~. The glass has an amorphous structure and resultant glass-ceramic mainly consisting of LiTi2（PO4）3 phases. Impurity phases AIPO4, TiO2, TiP207 and unidentified phase were observed. With the enhanced heat-treatment temperature, grain grew gradually and lithium ion conductivity of glass-ceramics increased accordingly, the related impedance semicircles were depressed gradually and even disappeared, which could be analytically explained by the coordinate action of the ＇Constant phase element＇ （CPE） model and the ＇Concept of Mismatch and Relaxation＇ model （CMR）. When the sample is devitrified at 1 000 ~C, the maximum room temperature lithium ion conductivity comes up to 4.1 x 10-4 S/cm, which is suitable for the application as an electrolyte of all-solid-state lithium batteries.展开更多
