Abstract:
This research proposes the design and development of a computer programming. Currently, there are many businesses using this program for supporting their operations process, to reduce costs and increase profits. In this study, there are three problems which should be solved. First, there are wasted papers up to 38.144 reams per month or 74.4 percent of company paper each month. Second, the company document printing costs up to 8,928 baht per month. Third, searching spends 29.20 minute per times. Therefore, this project aims to reduce disposal paper at least 20 percent, printing cost at least 20 percent and document searching at least 20 percent. The project started from research an information and works processing of the company, included time to searching for project documentation in order to define root causes by using Cause and Effect Diagram and FMEA for analyzing main causes of the problems. After using these tools the result has shown that the main cause of the problems is lacking of supporting programs. This research has solved this problem by designing and developing a computer program which can be able to reduce used paper, and searching period. The result has shown that after improvement, wasted paper reduced 66.86 percent, printing cost reduced 56.41 percent, searching period reduced 92.95 percent. Furthermore, the spending money is reduced from 174,230.78 baht to 60,772.06 baht and can support the job tracking and can show the reports of each achieved project
