It is argued in this paper that product, data, person and activity are basic factors in PDPM With detailed analysis of these basic factors and their relations in product developmed process, all product development activities are considered as tasks and the management of product development process is regarded as the management of task execution A task decomposition based product development model is proposed with methods of constructing task relation matrix from layer model and constraint model resulted from task decomposition. An algorithm for constructing directed task graph is given and is used in the management of tasks. Finally, the usage and limitation of the proposed PDPM model is given with further work proposed.展开更多

In recent years, with the gradual deepening of the aviation project management work research, many project management modes and project management methods have been gradually applied to the aviation product development project management work. Relevant staff needs to constantly improve their own quality, carefully formulate the project management methods and measures, form the aviation project management measures with their own development characteristics and promote the development of Chinas aviation industry.展开更多

It can be used to classify and register information including geometric features of the drawings, and to search appropriate reference drawings matching the given conditions of a new design. The thumbnails of the drawings can be displayed in an order of preference and can be used to zoom and access the PDF file or CAD data of a selected drawing. The thumbnails and the data structure are two key elements of the software.展开更多
