At this time, there is a tendency for<br>the demand of clean bottled water according to the increasing population. There are many bottled drinking<br>water entrepreneurs which are aware of the importance of production that can respond to the customers<br>need. Drinking Water Factory has the idea to increase the efficiency of the production process which has 6<br>steps as follows: filling water into empty bottles, closing the lid of the bottle and put into the cart,<br>transporting cart to the packaging room, arranging bottled water to the table, packaging wrapping, and air<br>blowing procedures. From the above processes, there was a problem in the transporting to the packaging<br>room process as it takes too much time. There are also redundant steps in transporting to the packaging<br>wrapping room and arranging the bottled water to the table. The staff has put the water bottle with no<br>systematic arrangement. Resulting in the process of arranging bottled water up the table taking too much<br>time to sort the researcher therefore has an idea to increase the efficiency of the bottled water<br>transportation process by using theKaizen concept: KAIZEN 7 QC Tool's and the PDCA quality management<br>cycle. By using of blocks and conveyor rollers to arrange the bottles orderly and easily, the transporting<br>process can significantly reduce work and process time.<br>The research result shows that the improvement of packaging transporting process by blocks and<br>conveyor rollers tools can improve the delay problem, reduce work, and reduce the time spent. The<br>original process time before the improvement was 371.91 seconds and the time spent after the<br>improvement reduced to 68.94 seconds or 81% less.<br><br></p> Thepsatri Rajabhat University, Industrial management technology Faculty of Science and Technology, Thonburi Rajabhat University Copyright (c) 0 https://ph02.tci-thaijo.org/index.php/IndustrialTechnology/article/view/241877 Sun, 05 Jan 2020 00:00:00 +0700 Forecasting for Production Planning: Integrated Circuit Factory Case Study https://ph02.tci-thaijo.org/index.php/IndustrialTechnology/article/view/241907 <p>This study aims to develop the forecasting production product for Integrated Circuit Industry by<br>considering the production of three products; TM-001 TG-001 and RM-012 with Time Series Analysis that<br>use 4 methods as follows; Trend Analysis Holt’s Trend-Corrected Exponential Smoothing Moving Average<br>and Single Exponential Smoothing. The result form forecasting production data with Minitab 18.0. We<br>found that Trend Analysis method was the best error measurement for product TM-001 TG-001 and RM012.<br><br></p> Thanakorn Miengarom, Prasit Krailomsom, Wolawit Leelawan Copyright (c) 2020 https://ph02.tci-thaijo.org/index.php/IndustrialTechnology/article/view/241907 Sun, 05 Jan 2020 00:00:00 +0700 Production Scheduling for Reduce the Process Time: A Case Study Warehouse https://ph02.tci-thaijo.org/index.php/IndustrialTechnology/article/view/241908 <p>The objective of this research is to 1) assess the practical process in warehouse department 2)<br>reduce the waste time of working process and 3) compare new methods with the existing method based<br>on priority rules. The experimental results show the working time of first come first serve method was<br>118.58 minutes and utilization were 0.82%. The shortest processing time method provided an average<br>job working time decreased by 16.60% when comparing to the existing method and worker utilization<br>increased by 7.51%. The longest processing time technique showed average job working time slightly<br>decreased by 0.20% and worker utilization decreased to 1.62%. Critical ratio method increased the<br>average job working time by 5.26 %, while worker utilization decreased to 4.27%. Least slack job rule<br>reduced both the average job working time and worker utilization by 5.57% and 1.20%, respectively. The<br>conclusion indicated that the shortest processing time technique was the most effective method due to<br>better solutions.<br><br></p> Thadawat Sriwilaiwat, Kantaphon Tantiwerabut, Anucha Hirunwat, Pasura Angkulanon Copyright (c) 0 https://ph02.tci-thaijo.org/index.php/IndustrialTechnology/article/view/241908 Sun, 05 Jan 2020 00:00:00 +0700 Deteriorated Lead-acid Battery Recovery Machine https://ph02.tci-thaijo.org/index.php/IndustrialTechnology/article/view/241912 <p>This research paper presents the design and construction of a depleted lead-acid battery<br>regenerator, focusing on 12 V, 75 Ah automotive batteries in general automotive applications. By choosing<br>to use a Buck converter circuit to generate a PWM signal to control the desired frequency and duty cycle.<br>Using a frequency of 20 kHz and a high frequency pulse technique to stimulate the battery. The<br>experiment will discharge before and after stimulation of the battery. To analyze energy storage and<br>discharge by connecting to a 150 W load, the results obtained were analyzed and summarized. Before<br>stimulation, energy is stored at 75 Wh after stimulation Store energy at 158 Wh Battery performance<br>After the experiment, the efficiency was increased by 109%, in line with the objectives set by the special<br>project team and in line with the relevant theories.
