This paper corrects an improper expression in the economic order quantity (EOQ) model with two-warehouses and imperfect quality developed by Chung et al. [2009. A twowarehouse inventory model with imperfect quality production processes. Computers & Industrial Engineering 56, 193-197]. The modiT ed model yields a simple and corrected expression for the optimal order quantity and expected proT t ...

the current research was done in order to determine contribution of components of quality of veterans’ wives’ life in prediction of their children’s general health. in this purpose 300 families (wife and child) were selected by random cluster sampling method from veterans’ families of hamedan province and quality of life questionnaire was administrated among veterans’ wives  and general  health...

The traditional inventory of the economic order quantity model assumes perfect items in an ordered lot and an infinite replenishment rate. However, such conditions are rare in actual production environments. Additionally, most studies of this problem have only considered suppliers offering the wholesaler a grace period. In practice, wholesalers often extend a fixed credit period to downstream c...

This paper is concerned with a discrete time, discrete state inventory model for items of changing quality. Items are assumed to be in one of a finite number, , Q of quality classes that are ordered in such a way that Class 1 contains the best quality and the last class contains the pre-perishable quality. The changes of items' quality are dependent on the state of the ambient environment. Furt...

a r t i c l e i n f o The optimal replenishment policy for an economic production quantity (EPQ)-based inventory model with nonconforming items and breakdown is presented. A real-life production system inevitably generates nonconforming items and has equipment breakdowns owing to process deterioration or other uncontrollable factors. This study addressed these issues in an EPQ-based system to o...

In this note, we correct some typos that appeared in Yassine et al. {Yassine, A., Maddah, B., Salameh M., Disaggregation and consolidation of imperfect quality shipments in an extended EPQ model, International Journal of Production Economics 135 (2012) 345–352}, specifically, for one of their models that considered consolidating shipments of imperfect quality items across multiple production cy...

This article deals with an economic order quantity (EOQ) inventory model for items with imperfect quality in fuzzy stochastic environment, wherein shortages are allowed and completely backlogged. Fuzzy stochastic environment means linguistic ‘impreciseness’ and statistical ‘uncertainty’ both appear simultaneously. Due to uncertain demand trend, imperfect production process, natural disaster etc...
