Purpose: The main objective of the paper is an analysis behaviour capability indices under different conditions. It assumed that metrological properties a check standard are correct, however, uncertainty affects evaluation measurement process capability. analyses individual cases influence bias and its on Methodology/Approach: Statistical both provided at beginning. Development possible cases, ...

this paper seeks two goals concurrently, at one hand tries to assay the capability of topsis, vikor and similarity-based approach as multiple attribute decision making approaches in evaluating mutual funds in iran stock exchange, and at the other hand in this evaluation tries to consider and compare three groups of indices including general evaluating indices (age, net value of mutual fund’s as...

Process tolerancing based on the process capability studies is the optimistic and pragmatic approach of determining the manufacturing process tolerances. On adopting the define–measure–analyze–improve–control approach, the process potential capability index (C p) and the process performance capability index (C pk) values of identified process characteristics of connecting rod ...

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...

Process capability indices have been widely used in the manufacturing industry providing numerical measures on process potential and process performance. Capability measure for processes with single characteristic has been investigated extensively, but is comparatively neglected for processes with multiple characteristics. In real applications, a process often has multiple characteristics with ...

The measurement of the process capability is a key part quantitative quality control, and indices are statistical measures capability. Six Sigma level represents maximum achievable capability, many enterprises have implemented improvement strategies. In recent years, studies investigated indices, including Qpk. However, Qpk contains two unknown parameters, namely δ γ, which difficult to use in ...

This paper builds on recent work on measuring and evaluating environmental performance of a process using statistical process control (SPC) techniques. We propose the CUSUM chart as a tool to monitor emissions data so that abnormal changes can be detected in a timely manner, and we propose using process capability indices to evaluate environmental performance in terms of the risk of non-complia...
