Construction cost estimation of municipal incinerators by fuzzy linear regression
- National Cheng-Kung Univ., Tainan (Taiwan, Province of China). Dept. of Environmental Engineering
Regression analysis has been widely used in engineering cost estimation. It is recognized that the fuzzy structure in cost estimation is a different type of uncertainty compared to the measurement error in the least-squares regression modeling. Hence, the uncertainties encountered in many events of construction and operating costs estimation and prediction cannot be fully depicted by conventional least-squares regression models. This paper presents a construction cost analysis of municipal incinerators by the techniques of fuzzy linear regression. A thorough investigation of construction costs in the Taiwan Resource Recovery Project was conducted based on design parameters such as design capacity, type of grate system, and the selected air pollution control process. The focus has been placed upon the methodology for dealing with the heterogeneity phenomenon of a set of observations for which regression is evaluated.
