The well-known process capability index CPK has been popularly used in the manufacturing industry for measuring process reproduction capability. Existing research papers related to CPK have assumed with no gauge measurement errors. Unfortunately, such assumption does not reflect real situations accurately even with highly sophisticated advanced measuring instruments. Conclusions drawn from proc...

This study examined the effect of agriculture faculty training in and practice of methodologies to explicitly teach critical thinking skills related to course content and subsequent change in student critical thinking disposition. Twelve instructors in 14 agriculture courses underwent a year–long program of instruction in effective critical thinking development. Students completed the Universit...

Process capability index Cpk has been widely used in the manufacturing industry as a process performance measure. In this paper, we investigate the natural estimator of the index Cpk, and show that under the assumption of normality its distribution can be expressed as a mixture of the chi-square and the normal distributions. We also implement the theory of hypothesis testing using the natural e...

Capability indices measure the performance of a process. Although process yield is the primary focus on the performance criteria, the " ( , ) p C u v indices combine process yield and process centering. With this compromise, there is no direct link between the process yield and these indices, but literature provides lower and upper bounds for the process yield. However errors in the proposed re...

A process is a unique combination of manpower, machines, methods and materials in providing a product or service. Process capability indices have been used in the manufacturing industry to provide quantitative measures of process potential and performance. High quality production provides advantages such as cost saving, reduced scrap or remanufacturing, higher yield and increased customer satis...

A new economic approach to process capability assessment is presented, which differs from the commonly used engineering metrics. The proposed metric consists of two economic capability measures – the expected profit and the variation in profit of the process. This dual economic metric offers a number of significant advantages over other engineering or economic metrics used in process capability...

The objective of this study is to examine why and under what situations certain information technology resources can generate positive organizational outcomes. To achieve this, we adopt the organizational capability perspective. Based on this perspective, IT can be viewed as a functional capability that forms highlevel dynamic capability in the copresence of other functional capabilities and re...

Greenwich and Jahr-Schaffrath (1995) introduced an index Cpp, a simple transformation of the index C∗ pm, which provides an uncontaminated separation between information concerning the process accuracy and process precision. Unfortunately, the index Cpp inconsistently measures process capability in many cases and thus reflects process potential and performance inaccurately. In this paper, we co...

The wind’s effectiveness was compared in different points of a watershed using a quantity called The Wind Shelter Index.The wind’s effectiveness was compared in different points of a watershed using a quantity called The Wind Shelter Index. It is necessary to choose a distance called the effective distance in the process of this index determination. The criterion already used for this purpose w...
