The feasibility study of noise disturbance in STW process

Because the problem of 9020 error code occurrence in STW process that effect to the time and resource in production process, the feasibility study of noise disturbance in STW project has been created and has the purpose of analysis and determination of 9020 error code occurrence and find the suitable method the solve the problem. This paper presents the feasibility study of noise disturbance in STW process. In this paper we studied STW process and its problem, analyzed noise disturbance in STW process, hypothesized the improvement method, did the experiment for determining the frequency and amplitude of Noise Disturbance and did the experiment for improvement methods. The results from experiment will be the advantage for implementation of system improvement that can decrease the effect of 9020 error code occurrence in STW process.
