Study of waste reduction in water meter installation process : a case study of provincial waterworks authority, Mae Sai Branch, Chiang Rai Province
Abstract:
The purpose of independent study was to study the procedures of installation water meter for increasing the performance of case study The Provincial Waterworks Authority at Mae Sai branch, Chiang Rai province. The researcher would like to use lean concept to minimize the operations waste. Moreover, the value chain concept would use to analysis the operation's procedure for creating performance suggestion.
The study found, there were 8 procedures or 26 activities of operating installation water meters, which total used 148.10 hours per 17 sets of water meters. There were 18 activities of value added, which used 125.77 hours or 84.92 percent of installation water meters. There were 7 activities of non valued added but necessary, which used 1.12 hours or 0.76 percent of installation water meters. There was 1 activity of non-valued, which used 21.21 hours or 14.32 percent of installation water meters. Therefore, the analysis of valued chain concept was able to reduce the procedure of installation water meters. Presently, there were 7 procedures or 22 activities, which total use 92.35 hours per 17 sets of water meters. There were 17 activities of valued added, which
use 90.50 hours. There were 5 activities of non valued added but necessary, which use 1.85 hours. In addition, the activity of non-valued was deleted, so the total operation use 55.75 hours or 37.52 percent of currently installation water meters. As improved, the procedure of the accuracy documents would take more concern to eliminate an error from operate which would make a postponement. Moreover, the researcher rearranges an order of procedures. The procedure of lump-sum appropriation (the price which PWA sets for hiring technician workers to install the water meters) is doing after the procedure of valuation (user or customer who needs to install the water meters) in order to make more stability in operating.
Comparing in the perviousness and subsequence proformance, the operations procedure of installing water meter performance of PWA in Mae Sai branch was improved from 148.10 hours into 55.75 hours per 17 sets for installing water meters, which is 37.64 percent of total reduction. Nevertheless, the currently lean valued chain of PWA in Mae Sai branch be able to agilely respond to 606 customers need also increase the performance of organization as aimed.
