The Importance of this paper is to account for the possibility dependence among items a sample. development new method designing sampling plans based on range quality instead point-wise description by invoking novel approach called Quality Regions. This seems be versatile and can adapted elementary production process where stipulated level advisable fix at later stage provides procedure meant i...

Our Call for Papers for a Special Issue on Emerging Markets in December 2000 generated 64 submissions. Of these papers, we selected seven papers, making the acceptance rate for this Special Issue in the same class as the very top finance journals. The selection procedure was as objective as possible. First, each submission was double-blind reviewed by two referees. The referees scored each pape...

Abstract In this research, a new acceptance sampling plan for truncated life test is presented, assuming that the quality characteristic follows power Lomax distribution. The operating function values are calculated proposed plan, jointly with optimal sample size and producer’s risk selection of distribution parameters. Furthermore, comparative study other plans introduced to demonstrate advant...

now a days, management and control of perishable inventories is important in many units and industrial enterprises. basically perishable inventory management and control is more complex and challenging than inventories with unlimited lifetime. hence determining the optimal inventory policies for these products is very important.  in this paper, the optimal inventory policy for perishable items ...

In the present study, a group-acceptance sampling plan was presented when lifetime of an item followed alpha power transformation-inverted perks distribution. The median is used as quality index to attain design parameters, such acceptance number and minimum group size, which are determined test termination consumer risk specified. operating characteristic values both graphically in form tables...

Most studies that follow subjects over time are challenged by having some subjects who dropout. Double-sampling is a design that selects, and devotes resources to intensively pursue and find a subset of these dropouts; then uses data obtained from these to adjust naïve estimates, which are potentially biased by the dropout. Existing methods to estimate survival from double-sampling assume a ran...
