However, planning methods of infrastructure projects are seldom investigated up to now. The authors propose a proper project planning method which is applicable to all kinds of infrastructure projects with various funedorigins. The project planning method includes a comprehensive planning frame- work and a six-step planning process. The financial indicator, i. e. , self-reimbursement ratio is introduced for the proper division of financial obligation between government and project company.展开更多

The application support platform of the ISLUPM, built based on COM, COM ＋ and .NET standard components, includes data engine, data management, assemblies, components management, operation management, and interface. Then, an elaboration was made on major functions of the ISLUPM, such as planning revision scheme, planning operation flow, digital processing, thematic analysis and inquiry, and preparation of the chart of reserved land resources. The developed system has been successfully applied to the land-use planning and management work of Longquanyi District, Chengdu, China. It may provide a reference for development of geographic information system （GIS） for land and resources.展开更多

In accord with review the aims and influencing factors are defined. The competitive behaviors of market participants, transmission losses, discrete investment costs, various operating conditions are considered in the model. The model is a mixed-integer linear programming formulation for a static TEP in the competitive environment. The presented methodology is applied to six-node system. In order to point out efficiency of the model the results obtained are compared with traditional problem solution.展开更多
