This research presents a Digital Twin of an Aquarium for Water Quality Monitoring, developing a virtual model that displays real-time key water parameters, including pH level, temperature, flow rate, and dissolved oxygen. Sensor data is processed and visualized through a Graphical User Interface (GUI) to reflect the real-time status of the virtual aquarium. This system enables accurate water quality monitoring and analysis while reducing reliance on expensive software solutions.
มีเป้าหมายในการสร้าง Digital Twin ของตู้ปลา เพื่อใช้เป็นกรณีศึกษาในการตรวจสอบคุณภาพน้ำ โดยนำเซ็นเซอร์ตรวจวัด ค่าความเป็นกรด-ด่าง (pH), อุณหภูมิ, อัตราการไหลของน้ำ และออกซิเจนละลายน้ำ มาประมวลผลและแสดงผลผ่านอินเทอร์เฟซกราฟิกแบบเรียลไทม์ ระบบนี้สามารถใช้เป็นสื่อการสอนด้าน คอมพิวเตอร์ช่วยงานเทคโนโลยีการผลิต โดยไม่ต้องพึ่งพาซอฟต์แวร์ราคาแพง ซึ่งช่วยลดต้นทุนและเพิ่มโอกาสในการศึกษา Digital Twin อย่างมีประสิทธิภาพ

Efficient logistics management requires the development of advanced tools to streamline delivery operations. This study aims to optimize vehicle routes for an animal feed store and develop a web-based application for route planning. The research compares two optimization methods: the Branch and Bound Method and Clustering with the Branch and Bound Method. These methods are evaluated against the store’s existing delivery route by analyzing differences in average travel distance across three dependent groups using Repeated Measures ANOVA. The findings reveal a statistically significant difference in average daily travel distances among the three methods at a 0.05 significance level. The Branch and Bound Method yields the shortest average daily travel distance. Additionally, pairwise comparisons of total daily travel distances using the Paired t-test confirm that the Branch and Bound Method produces the most efficient route with statistical significance at 0.05 level. Implementing this method can reduce total travel distance by 957.51, representing a 30.88% reduction, which translates into fuel cost savings of 2,579.45 THB per month. Based on these results, the Branch and Bound Method was selected for implementation in a web-based application. The application features an intuitive user interface, product inventory management, and optimized daily delivery route recommendations for the case study store. Following development, the web application was deployed and tested in real-world operations. The results demonstrate that it effectively provides map-based route recommendations, ensuring ease of use and accessibility on standard mobile devices.

This research aims to reduce the time required to resolve customer issues by focusing on improvements based on lean principles and the application of technology. The researcher conducts the case study at Nexter Digital and Solution Co., Ltd. to enhance workflows, establish new work standards, and integrate Bot technology into the processes to reduce resolution time and set new performance benchmarks for the company. The research proposes key ideas, such as identifying the root cause of problems, reducing redundant processes, implementing Lean methodologies, and applying technology to streamline operations. The research identifies two main issues to be resolved. The first involves addressing customer complaints, where the results show that the average resolution time reduces from 5 days to 3 days, representing a 38% decrease. The second issue involves solving problems for vendors, where the results show that the average response time reduces from 20 minutes to within 1 minute, a 98.5% decrease. The findings from both cases not only improve customer service but also establish a new standard for responding to and resolving internal issues more efficiently.
