The study of agricultural product's inventory is significant to lower its logistics cost, reduce the waste during the logistics courses and guarantee its quality. Deteriorating items can be studied by the way of literature review according to time varying of demand, inventory shortage and deteriorating rate while multi-warehouse according to the number of renting warehouse, capacity and demand ...

This paper develops a fuzzy inventory model for variable deteriorating items with time dependent two parameter Weibull demand rate. Shortages are allowed and partially backlogged. Each cycle has shortages, which have been partially backlogged to suit present day competition in the market. This inventory system follows a time varying holding cost. Here, the retailer is allowed a trade credit off...

Production systems with scrapped and rework items have recently become an interesting subject of research. While most attempts have been focused on finding the optimal production quantity in a simple production system, little work appears on a joint production environment. In this research, two joint production systems in a form of multiproduct singlemachine with and without rework are studied ...

In this study, a multi-item economic order quantity model with shortage under vendor managed inventory policy in a single vendor single buyer supply chain is developed. This model explicitly includes warehouse capacity and delivery constraints, bounds order quantity, and limits the number of pallets. Not only the demands are considered imprecise, but also resources such as available storage and...

Inventory models with imperfect quality items are studied by researchers in past two decades. Till now none of them have considered the effect of substitutions to cope up with shortage and avoid lost sales. This paper presents an EOQ approach for inventory system with shortages and two types of products with imperfect quality by one way substitution. Our model provides significant advantage for...

This paper outlines the preliminary results of the authors’ research study on one consortium’s interlibrary loan and collection development practices for returnable items. Local practices and policies that appear to have affected other member libraries are outlined. The audience will consider whether this analysis identifies concerns that they should investigate with their own consortium partne...

Background Face validation in psychometric testing of an instrument was used to identify incomprehensible items and hence increase the validity. However, conventional approach checking understandability older people respondents has its shortcomings. A new face asking for “interpretation” from recommended but lacked empirical research that compared these two approaches. This methodological aimed...
