| Popis: | 99 The objective of this study is to use risk analysis management method to help brand channels electronics manufacturers (“Brands”) to create an effective method for assessing risks involving hazardous material in green electronic products, in order to lower the risk of products being returned after the regulation is on effect, and even decrease the obligation to pay legally imposed damages. The method is to prevent shipped products being tested for violating RoHS requirements and the resulting large fines and loss of reputation. Through discussion with one of the Brands, this study actually analyzes the methods it uses to find the five risk factors stated in the RoHS regulations in its manufacturing procedures for its green component. These methods come from its operating procedures to control the content analysis created from the perspective of RoHS regulations. Further, these methods originate from data collected from 6,828 cases of assessing risk factors in green components, using the Decision Making Trial and Evaluation Laboratory (DEMATEL) method to find the relation structure among the five risk factors. Then the methods select the main origins for the risks in these green components and use the Analysis Network Methods (ANP) method to calculate the weighs of each risk analysis standards. Finally it uses the Failure Mode and Effects Analysis (FMEA) with the ANP weighs to create a method for calculating risks that allows for finding the weighted risk priority number (RPN) for each one of the risk analysis methods. As a result, it ranks the level of risk for each one of the 6,828 green components, allowing for improved prioritization of activities. From analyzing the actual result one can see that the Material Composition Declaration (MCD) can create standards for critical risk evaluation for high risk green component’s weighted RPN being too high. It also affect other major risk factors for risk assessment criteria, as it is the key risk indicators for green component in the risk assessment framework, followed by "Green quality monitoring feed-IQC controlled substances hazardous equipment". Further the stickers and sponges in packaging have the highest risk index, followed by heatsinks and fansinks. This becomes the highest prioritized object of improvement and monitoring for the decision-makers of the green components in their risk assessment framework. Through the risk assessment model for green components established by this study, along with incoming quality control (IQC) methods created by the Brand cited above, which together determine detection frequency of high risk green component, the risk assessment method for green components created by this study can use incoming quality control (IQC) working methods to improve the efficiency of the flow of risk analysis of green components. Such result can further limit the cost of performing incoming quality control (IQC) to the high risk components, reducing unnecessary component inspection by IQC staff workers, and lowering the risk of violating RoHS, and at the same time increasing reliability and scientific precision in decision result. |
