The nature of input materials is changed as long as the product reaches the consumer in many types of manufacturing processes. In designing and improving multi-stage systems, the study of the steps separately may not lead to the greatest possible improvement in the whole system, therefore the study of inputs and outputs of each stage can be effective in improving the output quality characterist...

Super MD Tile Factory is an individual business that engaged in the production of tiles small quantities. One products produced Mantili tile with make to stock and order systems. Defective process cannot be completely avoided. The company sets a tolerance for defective production, which 4.44%, but practice can reach 8%. Types defects such as porous, cracked, broken, cracked tiles, charred.The w...

The online quality monitoring procedure for attributes proposed by Taguchi has been critically studied and extended by a few researchers. Determination of the optimum diagnosis interval requires estimation of some parameters related to the process failure mechanism. Improper estimates of these parameters may lead to an incorrect choice of the diagnosis interval and thus huge economic penalties....

he effects of false and incomplete identification of nonconforming items on the properties of two-stage acceptance sampling procedures are studied. Numerical tables are presented, and there is some discussion of sensitivity to inspection errors. Methods of taking into account extra costs needed to implement better inspection techniques, when initial grading is inconclusive, are described. C-'> ...

In a recent paper, Ouyang et al. [10] proposed a ( , , ) Q r L inventory model with defective items in an arrival lot. The purpose of this study is to generalize Ouyang et al.’s [10] model by allowing setup cost ( ) A as a decision variable in conjunction with order quantity ( ) Q , reorder point ( ) r and lead time ( ) L . In this study, we first assume that the lead time demand follows a norm...

Automated processing and classiication of real-time X-ray images of randomly oriented touching pistachio nuts is discussed. The ultimate objective is the development of a system for automated non-invasive detection of defective product items on a conveyor belt. This approach involves two main steps: preprocessing and classiication. Preprocessing locates individual items and segments ones that t...

In this paper, a production inventory model is considered for stochastic demand with the effect of inflation. Generally, every manufacturing system wants to produce perfect quality items. However, due to real-life problems (labor problems, machine breakdown, etc.), a certain percentage of products are of imperfect quality. The imperfect items are reworked at a cost. The lifetime of a defective ...

Peter Facione's generally well thoughtout set of suggestions for messing up a critical thinking test l overlooked one significant option for the construction of defective multiple-choice (hereinafter MC) tests: require the impossible. 2 Perhaps Facione was being intentionally devious, leaving this option to be discovered by the intrepid reader, but it appears that one of the MC items he uses to...

familial defective apolipoprotein (apo) b 100 (fdb) causes early-onset coronary heart diseases (chd). it is produced by r3500q mutation of the apob gene resulting in decreased binding of ldl to ldl receptor. we screened the apo b gene for r3500q mutation in 130 hypercholesterolemic patients, among whom 30 patients met criteria of familial hypercholesterolemia (fh). the prevalence of r3500q alle...
