Baloui Jamkhaneh et al. (2008, 2009) have introduced a new acceptance sampling plan. In that plan the fraction of defective items is a fuzzy number. In this paper we introduce the average outgoing quality (AOQ) and average total inspect (ATI) for single sampling plan when that proportion nonconforming items is fuzzy number. We have shown that AOQ and ATI curves of the plan are like band having ...

We examine a reverse supply chain consisting of a collection site, where consumers return used products, and a remanufacturing facility. Some of the returned products are transported to the remanufacturing facility in order to be remanufactured and used to satisfy the stochastic demand for remanufactured products. The quality of returns is characterized by uncertainty, and therefore, before the...

A 1994 Maryland law prescribes a lead-based paint risk reduction standard for pre-1950, privately owned rental housing. This standard, applied at each tenancy change, can be met by sampling to verify that dust lead loadings are within acceptable limits or by performing specific lead hazard reduction treatments, followed by an independent visual inspection without dust sampling. We evaluated the...

Recently, 100% inspection using automated systems has seen more frequent application than traditional sampling inspection using human inspectors. Nevertheless, humans still outperform machines in most attribute inspection tasks. Studies have shown that hybrid inspection systems where humans work corporately with machines might achieve superior system performance than either humans or machines a...

Different signal processing and image reconstruction techniques are applied in ultrasonic non-destructive material evaluation. In recent years, rapid development in the fields of microelectronics and computer engineering lead to wide application of phased array systems. A new phased array technique, called “Sampling Phased Array” has been developed in Fraunhofer Institute for non-destructive te...

The paper presents a sampling-inspection strategy for the evaluation of time-dependent reliability of deteriorating systems, where the deterioration is assumed to initiate at random times and at random locations. After initiation, defects are weakening the system’s resistance. The system becomes unacceptable when at least one defect reaches a critical depth. The defects are assumed to initiate ...

Software-defined networking (SDN) is an emerging network technology that decouples the control plane from the data plane. Using SDN, a fine-grained flow-level inspection for cyber security can be performed by capturing suspicious packets on the network and steering the captured traffic to a traffic analyzer. This work proposes a flow inspection scheduling for various types of traffic flows on S...

Sanitary inspection, water quality determination and data analysis and interpretation are essential elements in characterising the microbiological safety of water in recreational areas. Sanitary inspection is a necessary adjunct to water microbiological analysis. A well-conducted sanitary inspection can identify sources of microbiological hazards, microbiological water quality data confirm the ...
