rangelands are important for plant productivity, livestock production, wildlife,conservation of soil and water resources, and etc. one of the main problem of rangeland isthat has not been used based on its potential that leads to more degradation of rangelands.the purpose of this study was to evaluate the range management capability of badrehregion in ilam province, iran, using anp (analytic ne...

There are practical situations in which the quality of a process or product can be better characterized by a functional relationship between a response variable and one or more explanatory variables, which is called profile. Such profiles frequently can be represented adequately using linear or nonlinear models. While there are several studies in monitoring profiles, there are few studies to ev...

Process capability indices PCIs aim to quantify the capability of a process of quality characteristic X tomeet some specifications that are related to ameasurable characteristic of its produced items. One such quality characteristic is life time of items. The specifications are determined through the lower specification limit L , the upper specification limit U , and the target value T . Maiti ...

Traditionally, the process capability index is developed assuming that the process output data are independent and follow normal distribution. However, in most environmental cases, the process data have more than one quality characteristic and exhibit property of autocorrelation. We propose two novel multivariate process capability indices for autocorrelated data, NMACp and NMACpm for the-nomin...

The SEI’s Capability Maturity Model for Software has popularized the notion of measuring the software process maturity of organizations. ISO’s SPICE project is currently creating a set of international standards for software process management that harmonize existing approaches. One of the objectives is to create a way of measuring process capability, while not using a specific approach such as...

Process capability indices (PCIs), Cp, Ca, Cpk, Cpm, and Cpmk have been developed in certain manufacturing industry as capability measures based on various criteria, including process consistency, process departure from a target, process yield, and process loss. It is noted in certain recent quality assurance and capability analysis works that the three indices, Cpk, Cpm, and Cpmk provide the s...

Process Capability indices have become popular for describing how well a process meets specified tolerances. The lack of affinity with the process nonconformance probability p and the difficulty of dealing with the sampling distribution of their natural estimators affect greatly the use of the traditional indices as Cp, Cpk, Cpm and Cpkm. In this paper, a capability index is proposed which is c...
