Unlike previous research, this study develops an integrated inventory model for controllable lead time with defective items, errors in inspection, and variable considering sustainability. The research investigates the effect of controlling capital investment setup cost. We assume that buyer receives a lot size may contain some items known probability. buyer’s inspector conducts 100% quality ins...

6 Many quality characteristics encountered in the food industry are compositional proportions, e.g. protein percentage in milk powder. The distributions of these quality characteristics are intrinsically not normal as well as cannot be well-approximated by it. Moreover the shape of underlying distribution of the quality characteristic in each lot is likely to change in a short-run production pr...

In the interval censored case 1 data, an event occurrence time is unobservable, but one observes an inspection time and whether the event has occurred prior to this time or not. Such data is also known as the interval censored case 1 data. It is of interest to assess the effect of a covariate on the event occurrence time variable. This note constructs tests for fitting a class of parametric reg...

This study proposes a new approach for single-sampling plan by determining sample size and acceptance number. The proposed approach is based on a two-step methodology. In the first step: quality management step, different single sampling inspection plans were generated by running an optimization model for different possible acceptance numbers. While, in the second step: Multi-Attribute Decision...

This paper illustrates the use of the Modulo Time Plot to facilitate diagnosis of data acquisition systems and components. While conventional techniques, involving spectral analysis and histograms, provide certain useful and necessary measures of performance, the use of reordered sample sets has gained considerable popularity in recent work aimed at characterizing analog-to-digital converter er...

Inspection of reflection line patterns is a standard way to check the quality of free form surfaces. In this paper, we describe an approach which enables the designer to control during the modeling process the reflection line pattern by approximating a specified family of reflection lines. Our method directly operates on the commonly used B-spline format, and produces fair surfaces. The approac...

The emphasis of this research was on the effect of human trust in a hybrid inspection system with varying error patterns. Experiments were conducted using a hybrid inspection task involving four common types of error patterns, and subjects were requested to rate their trust in the system at different stages. Results showed that subjects’ ratings of trust were based on how they perceived the beh...

Automated Visual Inspection Systems (AVIS) are becoming increasingly popular due to low cost maintenance and high accuracy. Ceramic tile factories, for example, are very much interested in these sorts of systems. This paper introduces a different strategy in ceramic tile inspection system to reveal four major problems, namely, edge curvature, thickness, size measuring and edge crack defects. It...

Defects introduced early in the effort to engineer a system due to poorly identified requirements are generally seen as a major factor leading to high system and software costs, especially if the defective requirements are undetected until later development phases in the lifecycle of engineering a system. In software development, inspection methods have been particularly successful when applied...
