An attempt is made to develop and verify the effective methodology of urban development projects planning, from the aspect of finance and administration. In the study, Kusatus City, Shiga Prefecture, is selected as the subject city for the case study. A financial simulation system has been built up, which is the analysis platform for the planning. The optimization of the study is linear multi-objective problem, with seven objective indexes correspond to the development objective the Kusatsu City, and four control variables of investment to living, transportation, culture, science and amusement, and welfare infrastructure. The hybrid model concept and time-related dynamic analysis are used in the planning evaluation for final proposal. And by the successful verification of the case study, it could be said that the planning methodology is rational and effective.
The demolition of buildings produces enormous amounts of waste materials that are hardly reused or recycled and therefore result in significant waste streams to landfills. This research aims to develop a Web-based information system for promoting management methodologies for demolition projects. Instead of the waste materials exchange in current online waste material management systems, this research aims to explore the possibility of exchange of demolition projects, by which the utilization of demolished materials may be ascertained before the demolition action is actually produced. With reference of the needs and difficulties of online drawing acquisition in architecture and building discipline, an online multimedia data acquisition tool is developed to collect the drawing data of a project to be demolished. Following the introduction for developing a Web-based distributed database system, a prototyped information system is demonstrated in detail through the system environment, structure and functions.
In the field of construction economics, input-output analysis based studies have attracted a lot of interest from the academics and researchers. The wide efforts are to carry out analyses and comparisons of economic indicators in construction sectors across countries and years. There has been little research modelling the construction productivity using input-output tables. This research takes advantage of the input-output analysis to develop a perspective for determining the productivity of an industrial sector. The developed quantitative formulas are fully based on the economic indicators generated from an input-output table. Using the newly published OECD input-output database, historical analyses and comparisons are carried out to indicate the differences of productivities of the construction sectors in Australia and Japan.
