- Increasing the Efficiency of the Bottled Water Packaging Process Movement
by Using the Kaizen Concept: Case Study Drinking Water Factory
Authors: Prasit Krai Lom Som, Thanakorn Myeong-amom, Worawit Leelamawan
Pages: A1 - A8
Abstract: Drinking clean, sterile and safe water will result in good health. At this time, there is a tendency for
the demand of clean bottled water according to the increasing population. There are many bottled drinking
water entrepreneurs which are aware of the importance of production that can respond to the customers
need. Drinking Water Factory has the idea to increase the efficiency of the production process which has 6
steps as follows: filling water into empty bottles, closing the lid of the bottle and put into the cart,
transporting cart to the packaging room, arranging bottled water to the table, packaging wrapping, and air
blowing procedures. From the above processes, there was a problem in the transporting to the packaging
room process as it takes too much time. There are also redundant steps in transporting to the packaging
wrapping room and arranging the bottled water to the table. The staff has put the water bottle with no
systematic arrangement. Resulting in the process of arranging bottled water up the table taking too much
time to sort the researcher therefore has an idea to increase the efficiency of the bottled water
transportation process by using theKaizen concept: KAIZEN 7 QC Tool's and the PDCA quality management
cycle. By using of blocks and conveyor rollers to arrange the bottles orderly and easily, the transporting
process can significantly reduce work and process time.
The research result shows that the improvement of packaging transporting process by blocks and
conveyor rollers tools can improve the delay problem, reduce work, and reduce the time spent. The
original process time before the improvement was 371.91 seconds and the time spent after the
improvement reduced to 68.94 seconds or 81% less.

- Forecasting for Production Planning: Integrated Circuit Factory Case Study
Authors: Thanakorn Miengarom, Prasit Krailomsom, Wolawit Leelawan
Pages: B1 - B8
Abstract: This study aims to develop the forecasting production product for Integrated Circuit Industry by
considering the production of three products; TM-001 TG-001 and RM-012 with Time Series Analysis that
use 4 methods as follows; Trend Analysis Holt’s Trend-Corrected Exponential Smoothing Moving Average
and Single Exponential Smoothing. The result form forecasting production data with Minitab 18.0. We
found that Trend Analysis method was the best error measurement for product TM-001 TG-001 and RM012.

- Production Scheduling for Reduce the Process Time: A Case Study Warehouse
Authors: Thadawat Sriwilaiwat, Kantaphon Tantiwerabut, Anucha Hirunwat, Pasura Angkulanon
Pages: C1 - C12
Abstract: The objective of this research is to 1) assess the practical process in warehouse department 2)
reduce the waste time of working process and 3) compare new methods with the existing method based
on priority rules. The experimental results show the working time of first come first serve method was
118.58 minutes and utilization were 0.82%. The shortest processing time method provided an average
job working time decreased by 16.60% when comparing to the existing method and worker utilization
increased by 7.51%. The longest processing time technique showed average job working time slightly
decreased by 0.20% and worker utilization decreased to 1.62%. Critical ratio method increased the
average job working time by 5.26 %, while worker utilization decreased to 4.27%. Least slack job rule
reduced both the average job working time and worker utilization by 5.57% and 1.20%, respectively. The
conclusion indicated that the shortest processing time technique was the most effective method due to
better solutions.

- Deteriorated Lead-acid Battery Recovery Machine
Authors: Natthawat Woranetsutthikun, Isaree Srikun, Parichat Kaensom, Ratchanon Sudsra, Apimook Svanperthan
Pages: D1 - D6
Abstract: This research paper presents the design and construction of a depleted lead-acid battery
regenerator, focusing on 12 V, 75 Ah automotive batteries in general automotive applications. By choosing
to use a Buck converter circuit to generate a PWM signal to control the desired frequency and duty cycle.
Using a frequency of 20 kHz and a high frequency pulse technique to stimulate the battery. The
experiment will discharge before and after stimulation of the battery. To analyze energy storage and
discharge by connecting to a 150 W load, the results obtained were analyzed and summarized. Before
stimulation, energy is stored at 75 Wh after stimulation Store energy at 158 Wh Battery performance
After the experiment, the efficiency was increased by 109%, in line with the objectives set by the special
project team and in line with the relevant theories. Make the battery last longer than that

- Calculation of inverter for photovoltaic power system for residential
building with program Visual Studio
Authors: Ouaychai Wongrat, Pichat Rattanaboontawee, Sitthut Madee, Adisak Thongchuay
Pages: E1 - E8
Abstract: The purpose of this project study Calculation of the inverter using Visual Studio 2017 program
by means of collecting all data on the conversion of solar energy to AC from solar cells while the
operation method starts from collecting data related to Battery calculation using pro visual studio 2017
with electric equipment, fan size (45w), TV size (37w), washing machine (200w), light bulb (15w),
fluorescent lamp (35W), air conditioner (1045w), pump. Water (400w) by inverter is used to convert DC
to AC depending on the number of solar panels used.
Therefore, from bringing various values Such as the electricity cost of electrical equipment inside
the residential building and inputting data into visual studio2017 program found that the size of the
battery of the photovoltaic power system 11610.82 Ah and I get 12 A, the total power is 327,835 w and
will get 14 inverters of 25 kw to get a total watt of 350,000 w.

- Calculation of battery size for photovoltaic power system for residential
building with program Visual Studio
Authors: Pichat Rattanaboontawee, Sitthut Madee, Ouaychai Wongrat, Adisak Thongchuay
Pages: E1 - E8
Abstract: This workflow study provides an idea of how to determine the size of the electrical system
walking in a residential building by means of data collection and control and navigation with the visual
studio dian program. Take advantage The building electricity is approximately 45 size, 37 electric beds,
200 washing machines, 15 electric lamps, 35 fluorescent lamps, 1,045 electric lights and 400 kilo water
pumps.
Therefore, from the rent, including electricity cost of electrical equipment inside residential and
