This research focuses on the raw-material management such as fuel of a case study company being a freight forwarder in Chonburi province. The objective is to determine the economic order quantity (EOQ) and the reorder point (ROP) that minimize the total cost of handling. Five forecasting techniques are investigated to predict the future demand and it was found that the time series decomposition was the most suitable method with the least error. At the result of demand forecasting the economic order quantity is 16308.89 liters per time the total cost of handling the fuel tank is 17287.43 baht and there are ordering around 19 times per year. In addition the sensitivity study on demand factors affecting the cost of fuel tank management are also considered in this paper. It was found that 21% of the increased fuel demand brings the total handling cost is 1728.74 baht or increasing 10%. Therefore ordering economically can reduce the total cost of 1295.97 baht or 6.85%. If the company brings the studied results to improve the ordering process it will be able to forecast the order quantity more appropriately and effectively.

The objective of this study is to improve the efficiency in manufacturing process of Arabian-style ventilation bricks with a new production method that uses a machine. The study focuses on all steps of productions in order to increase productivity. After the experiment the study shows that the improvement of ventilation brick manufacturing includes the increase in production volume from 20 pieces per day to 50 pieces per day representing an increase of 76.19 percent; and the decrease in production cycle time originally from 1401 minutes per piece to 97 minutes per piece representing a decrease of 93.07 percent respectively.

This research objective is to improve the overall equipment effectiveness of the water filtration systems in the case study of the Water Treatment Plant which divides the water production into 4 production lines. The water filtration system has an electric actuator and gear is the main machine in the water filtration system. An electric actuator and gear have more machine breakdowns. That makes the water filtration system is the bottleneck of the water production process. This research study is divided into two steps: the first step is the presentation of the equation and the steps to measure the Overall Equipment Effectiveness of the water filtration system. The equation used data from the computer maintenance management system to analysis on mean time between failure data (MTBF) mean time to repair data (MTTR) and water production process data. The results can be improved the overall equipment effectiveness of the water filtration system increased to 0.11% 0.68% 0.44% and 2.44% respectively in each production process line. And increased Quantity of Filtration Water increased to 328500 m3/year 1168000 m3/year 1022000 m3/year and 3832500 m3/year respectively in each production process line. In this research used the pillar of focus improvement. By adding a protection system to prevent machine breakdown because of the most of the problems are found that the protection system malfunctions. This is the most problem in the 4th And then used engineering knowledge to improve water production and the success factor are required a human resources of all parties to cooperate brainstorm and analyze the causes of various losses in order to eliminate them.

This research aims 1) Study the achievements of online teaching in a new way normal of Faculty of Architecture and Design RMUTP 2) Design online teaching media in a new normal of Faculty of Architecture and Design RMUTP 3) Assessing the achievement of online teaching in a new normal of Faculty of Architecture and Design RMUTP from 62 third-year students in the furniture design course for teaching through online programs There is a method for conducting research by looking at each type of program information for online teaching interviewing and then analyzing it. to determine the appropriateness for use as an online teaching medium and the process of creating presentation media selected from 8 to 1 by interview form 3 Associate Dean for Academic Affairs and Research from the Faculty of Architecture and Design RMUTP and 62 students of online teaching achievements were assessed in a new normal with Rating Scale.The results showed that a Google Classroom and Google Meet is most suitable for teaching online. Classroom is available to anyone using Google Apps for Education a free suite of productivity tools including Gmail Docs Drive and more powered by Google Classroom Google Meet has the highest average (𝑥̅=5.00 SD=0.00) Comparing the pre-study test scores with the learning achievement scores of the sample group it was found that pre-test at 15.29 (48.92%) and post-test at 24.82 (80.33%) was satisfied of 62 the students of the Faculty of Architecture and Design RMUTP had a high level of satisfaction with the overall assessment the mean (𝑥̅=4.08 SD=0.50). The satisfaction with a high mean was the use of online learning media while the test mean (𝑥̅=4.40 SD=0.44) followed by online media and online learning. Furniture design subject mean (𝑥̅=4.17 SD=0.48) followed by learning achievement of online learning users mean (𝑥̅=3.92 SD=0.50) and followed by Use online media for lesson content. Furniture design subject average (𝑥̅=3.84 S.D.=0.58)

This research 1] is to study the identity of Nora cultural art for developing the product values and promoting the products to international level and 2] to synthesize and develop the prototype pattern of the products by studying the material relationship between handicraft context and community and Nora cultural art. The research tools are questionnaire observation survey and focus group interview of total 150 people and conducting satisfaction surveys of 420 people such as people in Klong-Dan community tourists specialists and designers before designing the draft pattern by 1] evaluating purchasing factors of souvenir from Klong-Dan community identity in Songkhla province and 2] satisfaction level of graphic pattern and summarize using percentage and standard deviation as follow; The study has founded that 1] the most popular handicraft among tourists is the products from sedge (Krajood) weaving. The weaving processing principally concerns utility which can be made into cloths and costume products. The natural processing from sedge (Krajood) together with Nora cultural identity will made it well known among tourists in appearances colorful dressing from other materials mixing design and 2] the character of the pattern on the products from the satisfaction survey shows that the design of the pattern Nora-6 has total average of 4.25 the detail of graphic design has total average of 4.33 (SD =0.77) the pantone using in the handicraft has total average of 4.25 (SD=0.77) the handicraft detail has total average of 4.27 (SD = 0.74) the relationship and the importance of mind has total average of 4.25 (SD = 0.71) the product having symbols indicating communication elements has total average of 4.21 (SD = 0.76) and the pattern suitability has total average of 4.18 (SD = 0.72). The result of the pattern development will be another identity storytelling and the social context in the present together with the development of the local product could continue to commercial world
