This study is an academic article. By using a case study method (Case studies) the current situation of Thailand entering an aging society that causes a shortage of personnel to work. The objectives were to collect 1) knowledge and attitude toward Robotic Process Automation (RPA) system 2) cost effectiveness before and after using RPA system in the work process 3) the use of working time after using RPA in the process. operation, and 4) the efficiency of using the RPA system in the workflow. The analysis results showed that Robot software that mimics human behavior Where humans are the designers of the process (Process) and steps (Workflow) various decisions to make it work repeatedly. do it efficiently And reduce errors in work caused by human error and can also work 24 hours a day. which if we have a job that is a repetitive job to do regularly And many tasks may take a lot of time to do, will cause us to waste time on those tasks. Wouldn’t it be better to automate repetitive processes with repetitive tools? change repetitive tasks at chance of error It is a precise design process. And when going to use, there is less chance of error and RPA has the following business benefits: 1) Reduce errors in work caused by humans (Human Error) 2) Reduce costs, reduce costs because it can work. available 24 hours a day 3) Increased work efficiency by increasing Output and reducing errors 4) Making repetitive tasks no longer boring 5) It is not difficult to learn to create robots in many applications.
