As to the first research topic, we present a 'Noble Brand Positioning Four Master Phases Theory': Brand Space Theory, Brand Capital Theory, Brand Value Theory and Brand Circle Theory in advance. Following based on the Principal Component Analysis of statistical theory, we implemented the quantitative research in the 'Noble Brand Positioning Four Master Phases Theory'. We used the most famous fast food brand 'McDonald' s' as the sample space. The simulation test result shows that the Overall Index Explanatory Power is 83% under the Cronbath' s a is 0.88 through the quantitative verification. This result gives a strong support in defining the Noble Four Niche Phases Theory as the important strategic factor in establishing brand positioning index. After completing the quantitative research, the Principal Weight of each Sub-Niche is positive. This also implies that the Noble Brand Positioning Four master Phases Theory represents positive affection to brand positioning index. We also created the following Sub-Niches those are rarely mentioned in the past literatures. The Sub-Niches are:'Endless Running Strategy, Business Environment Strategy, Physical Capital Strategy, Brand Logo, Brand Music, Business Life Strategy, Personnel Capital Strategy, Life Cycle Strategy, Trust Mask Strategy, Re-Positioning Strategy, Word-Power Strategy, Globalization Strategy, Network Revolution Strategy and Green Brand Strategy'. The quantitative verification model can classify the responses of the sampling space into groups. After that, we used the quantitative verification process to classify the Target Consumer. And through the Principal Component Analysis, the group that owns the biggest average value consists of the Master Target Consumers for the business. This result would become the best suggestion for the business to adjust its strategies and to upgrade the productivity efficiency and create higher profit. As to the second research topic, we focused on finding the best corresponding characteristics attributes of the Brand Music for the Brand Log.

This paper presents an IFMC CAD model that consits of a geometry model and a material model, in which the geometry space acts as a base space and the material space acts as a bundle space. In this CAD model, the geometry model is based on the non-manifold model. In addition, a half-face data sturucture, which is derived from the half-edge data structure with the non-manifold feature of IFMC taken into account, is adopted to represent the geometry and topology information of the component. For the material model of IFMC, this paper focuses on the FGM component representation firstly and present a simplex-subdivision based CAD data exchange format, in which the material information is represented as a (n-1) simplex and material distributing feature is represented by the interpolation on the simplex-subdivision. Based on those, a part-building orientation optimization algorithm and an adaptive slicing algorithm for FGM component are presented in the paper. For the IFMC material model, the IFMC material information representation is divided into a meso-scale and a macro-scale representation. In the meso-scale, a concept named parameterized periodic functional meso-structure is presented as a unique form to represent the FGM (the homogeneous materials are regarded as a special FGM), the composite and the functional meso-structure material. The model of PMS is a three-tuple that contains the space state informatation, the material parameter and the material meso-scale distribution feature. The macro-scale material information representation is similar to the FGM components by interpolation of the control parameter of the periodical functional meso-structure based on the simplex-subdivision. Through an example of manufacturing-oriented IFMC CAD data processing, it is proved that the IFMC CAD model and the material information representation and process method proposed in this paper can provide a reliable data support for IFMC digital concurrent design and manufacturing.
