摘要:

A procedure is proposed for use in evaluating the effect of various control chart procedures. This consists of breaking the power curve associated with a particular control chart technique into four component parts. These are:γ1—probability of undercorrectingγ2—probability of overcorrecting, but still improvingγ3—probability of overcorrecting in excessγ4—probability of adjusting in the wrong directionThese components will be illustrated for a number of situations including Shewhart charts, partial correction procedures, geometrically weighted moving averages, cumulative sums, and an example which includes variability associated with the adjustments and variability in the process before adjustment.

摘要:

The no-intercept model“γ=βX+ error”is applicable in many practical situations. This article describes some of these applications, discusses special considerations in fitting the no-intercept model to data and indicates possible pitfalls. Caution in the use of the model is advised.

摘要:

A multiplex system, a system equivalent to a series ofnstructures ofmparallel elements which is sometimes called component redundancy, is studied and found to be superior to a parallel system consisting ofmparallel redundant structures ofnunits which is sometimes called unit redundancy. A guideline for the reduction of the probability of parallel system failure by the multiplex system whenn≤10,m≤4 is 1/nm-1ifƛt<.1 whereƛis the constant failure rate andtis the time of system operation. Additional isolation components and less than complete multiplexing (combination of multiplexing and parallel system) may offer reliability improvement in design when the physical act of complete multiplexing is prohibitive.

摘要:

In recent times there has been a resurgence of interest in the preparation, promulgation, and implementation of standards. A major objective of standardization is to establish and/or improve the quality of products, services, procedures, and so on. This objective is better-achieved if the standards themselves are of a high quality. In this paper, some of the existing standards are examined with respect to clarity of expression, technical acuity, and compliance-sampling procedures, in order to illustrate inadequate quality in these aspects. Some solutions are offered, including a procedure for obtaining a suitable sampling procedure for judging conformance in product standards or related documents.
