A comparison of sequential probability ratio and generalized attributes acceptance sampling plans
… made between Wald's Sequential Probability Ratio sampling plan, several generalized attributes acceptance sampling plans, and a curtailed single sampling plan. The evaluation of the plans is based upon a cost function based upon a combination of the Average Sampling Number (ASN) and the variance …

Optimizing sample plans to improve microbiological safety in a food processing plant
… and control their spread. An environmental sampling and monitoring program is an important tool that food manufacturers use to determine the effectiveness of their sanitation practices and pathogen control efforts. Guidance for initiating an environmental sampling plan and evaluating the …

Machine Learning from Computer Simulations with Applications in Rail Vehicle Dynamics and System Identification
… with a large number of rail vehicles). Since the sampling plan greatly influences the overall accuracy and efficiency of the stochastic predictions, various sampling plans are investigated, and a space-filling Latin Hypercube sampling plan based on the traveling salesman problem (TPS) is suggested …

Development, implementation, and economic evaluation of an integrated pest management program for alfalfa in Virginia
Three sampling methods for estimating abundance of alfalfa weevil (AW) larvae (Hypera postica Gyllenhal) were evaluated for both accuracy and precision. Calibration equations were developed to convert intensity estimates of AW larvae among sampling methods. Greenhouse experiments evaluating the …

The development and analysis of a multi-attribute quality control cost model
… can be expressed as C<sub>T</sub> = E (cost of sampling inspection). E (cost of accepting the lot). E (cost of rejecting and scrapping the lot). E (cost of rejecting and screening the lot). An optimal sampling plan can be obtained by determining the nᵢ and cᵢ, i = 1, 2, …, m, that minimizes …

Study on New Sampling Plans and Optimal Integration with Proactive Maintenance in Production Systems
<p>Sampling plans are statistical process control (SPC) tools used mainly in production processes. They are employed to control processes by monitoring the quality of produced products and alerting for necessary adjustments or maintenance. Sampling is used when an undesirable change (shift) in a …

An empirical assessment of the configural invariance of the brand personality scale : a comparison involving ethnic groups and brands in Canada
… 30 brands for the study, a stratified area sampling plan was executed to collect data from Anglophones and Francophones in Montreal, Quebec, Canada. 1959 questionnaires were distributed by field workers using area sampling within each selected census tract and 596 usable responses were …

Simultaneous process control of several independent quality variables
… the dual objectives of providing a true level of sampling error probabilities for the joint control of several quality variables while also giving problem diagnoses for the quality variables individually. The method is comprised of an afine transformation of the multiple quality variables which …

Surrogate optimization with algebraic notes and applications within the electromagnetics context
… methods, the repercussions of the choice of a sampling plan on these methods, and formalization issues regarding surrogate optimization with multiple low-fidelity models.

A software architecture towards automated data-driven multi-resolution crop scouting with an unmanned aerial system
… is necessary to track the status of crops planted in the field throughout the season. Developing a sampling plan to determine the path through the field and the number of points to sample helps minimize the amount of time spent scouting while maximizing the quality of information collected. …

Western corn rootworm damage assessment in Virginia and adult sampling with commercial yellow sticky traps
… yellow sticky traps and ear-zone regions of corn plants to predict subsequent damage to corn. Regression models for each sampling method were used to calculate economic thresholds of 20 adults per trap per wk for the Olson trap and 0.3 adults per stalk for the ear-zone visual count method. Adult …

Implementation of statistical process control in a high volume machining center : importance of control charts
… was brought back into statistical control. A sampling plan is determined and individual control charts are used to achieve real time inspection in the long term. As a result, scrap rate was reduced from 8% to 4% and potential savings in the column area is higher than $200,000. The SPC …

Risk Analysis Based on Performance Criteria: A Food Safety Control System and Decision-making Tool to Control Salmonella from Whole Broilers
… (PRMAs) to initiate risk analysis and to plan the risk assessment process. The information learned from these PRMAs should be utilized to construct a quantitative microbial risk assessment (QMRA) model. Then, risk management activities can utilize the QMRA model to identify and select …

Using single corn kernel classification, pooling, and simulation to address skewness and clustering in aflatoxin distribution
… contamination in a lot, one may adopt the bulk sampling approach to estimate the overall aflatoxin concentration in the lot, compare it against the aflatoxin action level, and decide whether to accept or reject the whole lot. The challenge with bulk sampling is that aflatoxin distribution is …
