Decision Support Making Process For Efficiency Improvement of Drinking Water Processing Using Retrofit and Analytic Hierarchy Process
MetadataShow full item record
The objective of this research was presented a decision support making process for efficiency improvement of drinking water processing using retrofit technique for machine and equipment rehabilitate. This methodology was applied Analytic Hierarchy Process (AHP) for selecting an appropriate maintenance sub-contractor. To complete the research, existing water purifying machine and tools were inspected to assess its capacity. Future capacity of the purifying machine was also identified. Consequently, machine and tools such as water tank and water filter were inspected for retrofitting for the example water tank, water filter, water quality control, and bottle packing. Finally, the analytic hierarchy process was utilized to select the most appropriate maintenance sub-contractor. In this process, both qualitative and quantitative processes were analysed. The result of this research has been found that this multicriteria decision making process could be used to support the decision making investment process of water purification retrofit unit at Faculty of Engineering, Rajamangala University of Technology Phra Nakorn efficiently. Furthermore, it could be reduced bias from decision makers while the decision was accepted by all stakeholders.
