Sintering integrated control model management framework based on distributed observer pattern

For the execution and technologies related to the concept system, its innovation focuses on execution feasibility from the commercial perspective. The greatest innovation in terms of execution is in the combination of international technological trade mechanisms. In the past, many international technological transfers were erroneously interpreted and analyzed. The emphasis on the fact that the international technological transfer itself is a commercial practice is an innovative proposition. That is to say, the practices involved are in line with the international practice and the international trade rules. Only the transfer that generates profits can be considered a successful transfer. Thus this research paper proposes that the Three-tier control model for the international technological transfer become an integrated control mechanism, described the key problem in this mechanism. No matter how many standards you set, if you cannot find a real foothold in the market and generate profits, any standards are of no avail.

Data Access Control

Property of transmission system will directly influence the performance and reliability of helicopters. Information exchange and sharing are difficult in transmission system life-cycle, which has complex product to fabricate and mass information to handle. To solve this problem, we establish a unified product data (UPD) to manage the information of research-development process for transmission system. In distributed collaborative environment, a single enterprise UPD is established by analysing transmission system development process and data flow. The theoretical frame of UPD and several key techniques are studied, including architecture, model, management, consistency, and mapping of data access control. Data integration and data access control model in development process is discussed in this paper. A UPD integration framework based on collaborative agent is presented, which shows the evolvement theory among PUPD, DUPD, SUPD and IUPD. Besides, task-role-based access control model is proposed, and dynamic right control process is given for UPD.

Fidelity Model

Research applications involving design tool development for multiple phase material design are at an early stage of development. The computational requirements of advanced numerical tools for simulating material behavior such as the finite element method (FEM) and the molecular dynamics method (MD) can prohibit direct integration of these tools in a design optimization procedure where multiple iterations are required. The complexity of multiphase material behavior at multiple scales restricts the development of a comprehensive meta-model that can be used to replace the multiscale analysis. One, therefore, requires a design approach that can incorporate multiple simulations (multi-physics) of varying fidelity such as FEM and MD in an iterative model management framework that can significantly reduce design cycle times. In this research a material design tool based on a variable fidelity model management framework is presented. In the variable fidelity material design tool, complex “high fidelity” FEM analyses are performed only to guide the analytic “low-fidelity” model toward the optimal material design. The tool is applied to obtain the optimal distribution of a second phase, consisting of silicon carbide (SiC) fibers, in a silicon-nitride (Si3N4) matrix to obtain continuous fiber SiC-Si3N4 ceramic composites (CFCCs) with optimal fracture toughness. Using the variable fidelity material design tool in application to one test problem, a reduction in design cycle time around 80 percent is achieved as compared to using a conventional design optimization approach that exclusively calls the high fidelity FEM.
