This research is derived an integrated model of economic production quantity, inspection and preventive maintenance to incorporate rework, minimal repair and inspection time for an imperfect production system. Some proportions of non-conforming items are assumed scrap before the rework process start and others are reworked. The rework process is imperfect that is a proportion of the reworked it...

introduction: cochlear implantation (ci) improves language skills among children with hearing loss. however, children with cis still fall short of fulfilling some other needs, including musical perception. this is often attributed to the biological, technological, and acoustic limitations of cis. emotions play a key role in the understanding and enjoyment of music. the present study aimed to in...

This paper investigates optimal replenishment lot size and optimal number of shipments for economic production quantity (EPQ) model with rework process using an algebraic approach. The classic EPQ model assumes a perfect quality production for all items produced and a continuous issuing policy for satisfying customer‟s demand. However, in a real life vendor-buyer integrated-production-inventory...

We presented a closed loop structure with remanufacturing for decaying items. The model is considered for single item with two different quality standards. A mount of product is collected from the user. After collection process, a ratio of the collected items is to be remanufactured. Furthermore, a salvaged option is considered within the structure in study. In practices, remanufactured items a...

Traditionally, the inventory models available in literature assume that all articles purchased lot are perfect and demand is constant. However, there many causes provoke presence of defective goods dependent on some factors. In this direction, paper develops an economic order quantity (EOQ) model for imperfect quality items, taking into account ones sent as a single to repair shop reworking. Af...
