Description
Summary:碩士 === 國立雲林科技大學 === 營建工程系碩士班 === 97 === In highway contstruction stage, changing of project design usually casues problems, such as its cost and budget control. Also, it affects the smooth going of the project. Changing of project esign during construction not only will increase the cost budget but also delay the progress of the project. Therefore, this study was aimed to find out the reasons of changing the project design by analyzing questionnaire. Also, using Grey Relation Analysis examined the correlation and the sorting. The study involved literature review and comprised of experts’ interview in order to find out the factors that affect the changing of project design in the construction and its solution. There were two phases in data collection procedures. In the first phase, experts interviewing was conducted in order to find the factors that influent project change design. Then, five-Likert scale questionnaiare was conducted in the second phase of data collection procedures. The data were collected and analyzied by using Fuzzy Multiple Attribute Decision Making and Gray System Theory to discover the change design in construction and to manage the important sorting of its solutions. It was anlayized the difference of sorting among different department, working period and the job duty and was dicussed its meaning. Results of this study were showed in the following. First, the most influency factor among chaning of project esign was the out of production of the material or out of stock. Second, among managing solutions in changing of project design, the most important sorting was calculating the quantity of project precisely. Third, public opinion and requests for addition measure was the influencing factors in the cost control. Then, among cost control management, simplied project design changing procedure was the important sorting factor. That is, by chi-quare testing, the planning department and public opinion were the most influencing factor in project changing design. Also, it was expected in cost control management to simplify the procedure of changing design. This study presents the sorting of highway project changing design in construction and its influencing factors in cost contral. It is expected that this study could provide some references of managing and improving measure to relavent department when they are planning projects.
