EPQ model for imperfect production processes with rework and random preventive machine time for deteriorating items and trended demand
Economic production quantity (EPQ) model has been analyzed for trended demand, and units in inventory are subject to constant rate. The system allows rework of imperfect units, and preventive maintenance time is random. A search method is used to study the model. The proposed methodology is...

description | Economic production quantity (EPQ) model has been analyzed for trended
demand, and units in inventory are subject to constant rate. The system
allows rework of imperfect units, and preventive maintenance time is random.
A search method is used to study the model. The proposed methodology is
validated by a numerical example. The sensitivity analysis is carried out to
determine the critical model parameters. It is observed that the rate of
change of demand, and the deterioration rate have a significant impact on the
decision variables and the total cost of an inventory system. The model is
highly sensitive to the production and demand rate. |
