The classic E...

We consider the fundamental limits on the number of tests required for the group testing problem,which has applications in medical testing, fault detection, communication protocols, pattern matching,and database systems. Specifically, we have p items labeled {1, . . . , p}, among which a uniformly randomsubset S of cardinality k are defective. The goal is to recover the set S ba...

 Imperfect production processes lead to imperfect products and decrease the profit of a business. Improvement in the production process by increasing the investment cost will decrease the defective percentage of items. This study develops an EPQ model with investments on imperfect production processes under limited capital. An algorithm is developed to derive the replenishment and investment p...

Running the business smoothly for protecting environment is a significant challenge, on which industries are trying something to do at their level best. Reverse logistics play an important role in system design by reducing environmental consequences and increasing economic social impacts. Given recent fluctuations of market, production cost ordering considered triangular fuzzy numbers this stud...

This paper provides a short introduction to the group testing problem, and reviews various aspects of its statistical physics formulation. Two main issues are discussed: the optimal design of pools used in a twostage testing experiment, like the one often used in medical or biological applications, and the inference problem of detecting defective items based on pool diagnosis. The paper is larg...

a r t i c l e i n f o Keywords: Supplier–retailer inventory system Trade credit Defective items Variable production This paper investigates an integrated inventory model with variable production rate and price-sensitive demand rate under two-level trade credit. The model considers two-level trade credit policy in which the retailer receives a full trade credit from its supplier, and offers part...

Abstract In this paper, we consider the problem of noiseless non-adaptive probabilistic group testing, in which goal is high-probability recovery defective set. We show that case $n$ items among $k$ are defective, smallest possible number tests equals $\min \{ C_{k,n} k \log n, n\}$ up to lower-order asymptotic terms, where $C_{k,n}$ a uniformly bounded constant (varying depending on scaling wi...

this study deals with a two-level supply chain consisting of one manufacturer and one retailer. we consider an integrated production inventory system where the manufacturer processes raw materials in order to deliver finished product with imperfect quality to the retailer, where number of defective product has a uniform distribution. the retailer receives product and conducts a 100% inspection....

This lecture is about different techniques used for video streaming to improve performance and Quality of Experience (QoE). Specifically, we learned about ”neural adaptive video streaming with Pensieve” [1]. Pensieve adaptively selects bitrates (ABR) for future video chunks based on observations collected by client video players. It automatically learns ABR algorithms that adapt to a wide range...
