Production inventory model with reworking of imperfect items and integrates cost reduction delivery policy

The Impact of Online Shopping in Boosting Sales and Cost Reduction in Commercial Companies

“…This is quite different from a previous study which was conducted by (Sanjai & Periyasamy, 2018). They integrated cost reduction delivery policy into production inventory model.…”

Cost-Effective Imperfect Production-Inventory System under Variable Production Rate and Remanufacturing

“…A detailed comparison is presented in Table 9. Due to the use of a flexible production system, an assembled product, and single-stage manufacturing and remanufacturing, the present study reduces costs more than twenty times compared to the models of Sivashankari and Panayappan [9] and Sanjai and Periyasamy [10]. On the other hand, the cost of this study is more than seven times higher than that of C árdenas-Barr ón's [4] and Sarkar et al's [5] models.…”

“…However, the concept of an assembled item, where each part of the item is manufactured and remanufactured in the same generation cycle with a flexible production rate and different distributed defect rates, was neglected by Sivashankari and Panayappan [9], which increased the system cost tremendously. Similarly, Sanjai and Periyasamy [10] proposed a production-inventory system with imperfect generation under different delivery policies. They neglected the concepts of variable production rates and assembled products.…”
