Abstract
This study aims to evaluate the risks that may arise during the production process in a plastic injection manufacturing enterprise with traditional Failure Mode and Effect Analysis (FMEA) and Grey Relational Analysis (GRA). Although it is a widely used analytical technique that helps to identify and reduce the risks of failure in a process, the Failure Mode and Effects Analysis (FMEA) has some drawbacks that the different risks can have the same risk priority values and the weight of risk factors is not take into consideration. This situation has been tried to be eliminated by integrating the FMEA with the GRA. As a result, it is seen that the order of risk priority values of the identified failure changes according to both methods.
Highlights
All businesses in the service or manufacturing sector face risks and hazards from internal and external factors
This study aims that in order to reduce the damages to the business by eliminating the failures that occur in a plastic injection production business, in addition to the Failure Mode and Effects Analysis technique, the Grey Relational Analysis technique has been applied and the risk priorities have been compared according to two techniques and the effects of the methods on the results have been investigated
The purpose of the Failure Mode and Effects Analysis (FMEA), which was first introduced into the literature by the application of the American Army and NASA, is to detect and correct the potential problems in the design and production processes [2,3]
Summary
All businesses in the service or manufacturing sector face risks and hazards from internal and external factors. Failures that occur during production are difficult and high cost to compensate after they reach the customer [1] For this reason, especially mass production businesses need to keep their risks under control. The failure rates that occur in the production step in the mass production businesses like plastic injection are very high and this situation leads up both economic inefficiency and loss of confidence in customers for businesses. This study aims that in order to reduce the damages to the business by eliminating the failures that occur in a plastic injection production business, in addition to the Failure Mode and Effects Analysis technique, the Grey Relational Analysis technique has been applied and the risk priorities have been compared according to two techniques and the effects of the methods on the results have been investigated.
