| 摘要: | The equipment in the factory will gradually deteriorate during production, leading to the pro-duction of defective products. Without appropriate maintenance, the defective rate will increase over time. Consequently, the production cost will rise, the inventory quality will be affected, the profit will decrease, and the risk from carbon emission will increase, leading to more customer complaints and damaging the corporate image. In addition to focusing on preventive mainte-nance to assure the quality of product, companies should also take carbon emissions into con-sideration. Furthermore, the frequency of maintenance must be carefully considered, as both carbon emissions and maintenance costs will increase if the frequency is too high. Conversely, if the maintenance frequency is too low or even no maintenance, the defective rate may increase cumulatively, or production may be suspended due to equipment failure. Therefore, this research explores preventive maintenance and inventory management issues within the imperfect pro-duction system and develops an extended economic production quantity model that incorporates defective products as well as takes carbon tax and preventive maintenance into consideration. The main purpose is to determine the optimal maintenance frequency, production and replenishment cycle length, so as to maximize the total profit under the carbon tax policy. This study demon-strates computing process with relatively impractical product data based on the actual business situation of the disposable diaper manufacturer. Further, the sensitivity analysis is implemented to the model parameters in the proposed model. The managemental insights are illustrate based on the results of theoretical analysis to provide the reference to policy makers during the decision making, hence to secure the sustainability and green transitions of corporates. The results of this study not only help reduce environmental impact, but also improves the competitiveness and sustainable development of enterprises. |
