Based on the summarization of weighed set and assessment matrix methods in the fuzzy integrated estimation theory,the paper uses the degrce analyse method and gathering statistics iterative method to determinate the estimation matrix and weighted set for the sake of objectivity.

The surface height can be reconstructed accurately from a synthetic image by the iterative calculus,which provides a feasible approach for extracting the surface shape of fabric image.

The accuracy of iterative calculus was verified by recovering surface height of an object from its synthetic image, and the application of the calculus has been extended to reconstruct surface height from remote sensing image.

Mission reliability of development system based on the design iteration and resource confliction

Moreover,characterization of the task structure in product development process,management of the dependency relationship among entity elements,modular clustering of system structure,and identification and optimization of design iteration were studied.

With consideration that the completed times of design activities follow arbitrary distribution and design iteration dose exist,an optimized model has been established which provides a new solution method for the development process optimization problems.
