A smed approach proposal with ergonomic risk assessment and grey-based taguchi method - an application

In this study, the posture detected in the workshop to a maximum downtime caused by increasing the efficiency of production efficiency and ergonomically employees working on making the setup process is intended to more effectively shortening time. In this research, there are two innovations. The first single minutes exchange of dies (smed) time reduction is made according to the method, after the method of ergonomic risk assessment methods on the basis of the new smed approach was developed by Sue Rodgers. The shortening of the duration of steps in the installation process while making improvements to the machine for ergonomic risk assessment will be done to essential organs in the human body and the risk of work will be evaluated. Risk will be related to fatigue and injury. Being tired with the activities proposed risk mitigation will decrease, thus, will lengthen the processing time and also a slowdown because of injuries or inability to work will be obtained more effective situations will be eliminated because the time to heal. With the reduction of the risk it is envisaged that the work will reduce the time of construction. However, some improvement can be attained with an effective SMED process steps in traditional applications. In such cases, the method should take advantage of some improvement. The second innovation in the study could not be performed to improve the time and very little improvement to be expected by reducing ergonomic risk in the process components at the same time the application of experimental design in order to achieve the improvement. Improving takes time and risk, such as grey taguchi method for multiple answers, because this two is the value-based Taguchi method was used. This study shows, more effective results can be obtained with the traditional SMED applications with time can not be shortened and the high level of risk based on a common process step grey with Taguchi method. At the same time the high level of risk on employees with ergonomic risk level and component of the process to reduce the time available by appropriate factors to identify those factors experimental setup process step of forming the current setup time has been shown to be reduced. With the implementation of the developed model, in the first case,196 minutes the installation processing time reached 73,5 minutes and the final state is obtained an improvement value of 62,5%.
