Task Manager Key Technology Research And System Development

Innovation in products is the key force to market competition. Especial for enterprises, it is the capacity to develop new products that is one of the most important parts to the core competitive capacity. For the products becoming more and more complex, it is necessary to develop an aided system of Product Development Process Management (PDPM), of which, the Task Management is a key subsystem. In the task management, the task content is defined detailedly to reduce the difficulty in the task's implementing, and the task distribution is optimized to let the worker match up to the task, and the task lifecycle is tracked to control the task 's schedule. On the work of them, it is reached that the aim of shortening the time spent on product development.Firstly, in this paper, the status and problem of task management in Project Management, Workflow Management and Product Data Management applied to the Product Development Process Management is analysed. And the study status of the algorithm and management of the task distribution is discussed. On the basis of these, this paper's research meaning is summed up.Secondly, after analysis of the task management's situation and abuse in the item management section, yield section and design section in Xi'Fei Company, several methods to optimize an enterprise's task management are put forward under the guidance of resolving problem one by one, such as defining the task in detail and developing a computer aided system of task management. And the operating theory of the task management is designed based upon its basic flow.Then, founded on the requirement analyzing on function and data and capability of Computer Aided Task Management System (CA-TMS), the system structure is fixed to adopt the Client/Server structure after the compare of three kinds of system structure. Farther, the subsystems are carved up, and at the same time, their functions are confirmed. In succession, the function model pictures (IDEFO) are drew by the function requirement and the information model pictures (IDEF1X) are drew by the data requirement, and the database is planned.At last, the software programming and application of the CA-TMS are described. And several key techniques in programming are discussed, such as, the selection of the database's operation mode and Excel's transfer.
