However, the process to set up the IoT platform is complex and time consuming for some IoT developers. Thus, this paper presents the design and development of an MQTT-based IoT cloud platform with flow design by Node-RED to help developers save time to set up the IoT platform by themselves. The user interface of this platform is in the form of a web application developed with the MERN stack. The platform provides three main services: (1) MQTT broker for data transmission (2) Node-RED for designing the flow of data processing and displaying data in graphical form via Dashboard and (3) InfluxDB and MongoDB databases for storing data. These services operate as containers running on the Docker. The web application connects to the Docker via Docker API using the Dockerode library to start, stop and get the status of the containers. Using the test by making an IoT system for monitoring and displaying temperature values, we found that our platform can support and help users in developing the IoT system very well. The developers who want to develop IoT systems do not need to set up an IoT platform by themselves.","PeriodicalId":404700,"journal":{"name":"2019 Research, Invention, and Innovation Congress (RI2C)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134230230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Simulation of Queueing System for Commercial Bank in University: Case Study of Bangkok Bank at King Mongkut's University of Technology North Bangkok 大学商业银行排队系统模拟——以北曼谷蒙库特国王理工大学曼谷银行为例

In this study, the current queueing system with a single queue and three service channels is considered by collecting the data in three periods, 8:30 a.m.–10:30 a.m., 11:30 a.m.-1:30 p.m. and3:30 p.m.–5:30 p.m. from 2nd September to 27th November 2015. Moreover, the new queueing systems are considered by increasing or decreasing the service channels and changing the queueing structure from single queue to multiple queue. The average waiting time, the average total time, the average queue length and the average work in process are considered as the key performance measures in order to show the efficiency of the service. The simulation results, by using the Arena program, show that the appropriated service for the first time period, 8:30 a.m.–10:30 a.m., is the queueing system with the single queue and three service channels. In addition, the appropriated service for the second time period, 11: 30 a.m.–1:30 p.m., is the queueing system with the single queue and four service channels. Finally, the appropriated service for the third period, 3:30 p.m.–5:30 p.m., is the queueing system with a single queue and two service channels.","PeriodicalId":404700,"journal":{"name":"2019 Research, Invention, and Innovation Congress (RI2C)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129722291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Only in-class lecturing is not enough, and hand-on practices are very important, in which theory and practice can be integrated to create knowledge and skills simultaneously. Although there are many learning tools available for practicing with sample exercises, they are not enough for students to understand properly especially in the subject that are abstraction and requires imagination. This paper presents a didactic tool for a study of leveling control system which maintains the surface level using multiple sensors including IMUs and ultrasonic sensors, and multiple models including digital filters, coordination, digital automatic control, and kinematic model. The data obtained from the IMU are used to calculate the tilt angle using the complementary filter method, and from the ultrasonic sensors are used to find the distance between the platform and ground using low-pass filter. The difference tilt from both roll and pitch angles and the distance are used to control the tilt angle and the correct distance using the PID controller. This system can be used to study IMU sensor functions, digital signal processing and digital controller as well, and will enable students to understand and use the sensor system to easily create automatic control systems in the future.","PeriodicalId":404700,"journal":{"name":"2019 Research, Invention, and Innovation Congress (RI2C)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132511088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the unsafe workplace, workers in the job rotation program will be assigned to workstations with low or high occupational hazards so that 8-hour exposure to each hazard of all workers will not exceed the permissible exposure limits. When dealing with a high hazard level, the number of workers required for job rotation is possibly more than the number of workstations because some workers in some periods will be assigned to perform tasks in the safe areas. Therefore, this paper proposes the optimization approach to solve the mixed-integer programming models that try to minimize the number of workers used in job rotation under noise hazard and air contamination. The numerical experiments are provided to demonstrate the solution procedures. Finally, the effectiveness of the branch and cut search in an optimization software namely CPLEX is also discussed. Within the computational limit, CPLEX can determine the optimal solutions for small size problems and the feasible solutions for large size problems.","PeriodicalId":404700,"journal":{"name":"2019 Research, Invention, and Innovation Congress (RI2C)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132707515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
