The Evolution of the Continuous Representation for Process Capability
نویسنده
چکیده
A continuous representation model characterizes a set of processes by a structured set of process attributes, typically organized into six Capability Levels. The continuous representation is a flexible and easily extended architecture, so understanding its evolution can be helpful to those wishing to use a continuous representation model or to adapt it for different environments. The reference model in ISO/IEC 15504 includes a “continuous” process capability dimension that has evolved to address conflicting requirements and that has been adapted for a variety of other improvement frameworks, including the Systems Engineering Capability Maturity Model (SE-CMM), the Software CMM, and CMM Integration (CMMI). The evolution of the continuous representation in ISO 15504, and the variants developed for other frameworks, capture a tradeoff between reliability and usability that remains a challenge for model developers today. The purpose of this paper is to describe the evolution and the important variants of the ISO 15504 continuous representation with a discussion of the objectives and tradeoffs associated with each.

Introducing Triangular Fuzzy Process Capability Indices to Evaluate Performance of Continuous Production Process
Process capability indices (PCIs) can be used as an effective tool for measuring product quality and process performance. In classic quality control there are some limitations which prevent a deep and flexible analysis because of the crisp definition of PCA‟s parameters. Fuzzy set theory can be used to add more flexibility to process capability analyses. In this study, the fuzzy X ba and MRx ba...
متن کاملApproximation of fixed points for a continuous representation of nonexpansive mappings in Hilbert spaces
This paper introduces an implicit scheme for a continuous representation of nonexpansive mappings on a closed convex subset of a Hilbert space with respect to a sequence of invariant means defined on an appropriate space of bounded, continuous real valued functions of the semigroup. The main result is to prove the strong convergence of the proposed implicit scheme to the unique solutio...

We introduce a general implicit algorithm for finding a common element of the set of solutions of systems of equilibrium problems and the set of common fixed points of a sequence of nonexpansive mappings and a continuous representation of nonexpansive mappings. Then we prove the strong convergence of the proposed implicit scheme to the unique solution of the minimization problem on the so...

In this study, a mathematical model is introduced to simulate the coupled heat transfer equation and Stefan condition occurring in moving boundary problems such as the solidification process in the continuous casting machines. In the continuous casting process, there exists a two-phase Stefan problem with moving boundary. The control-volume finite difference approach together with the boundary ...
متن کاملContinuous dependence on coefficients for stochastic evolution equations with multiplicative Levy Noise and monotone nonlinearity
Semilinear stochastic evolution equations with multiplicative L'evy noise are considered. The drift term is assumed to be monotone nonlinear and with linear growth. Unlike other similar works, we do not impose coercivity conditions on coefficients. We establish the continuous dependence of the mild solution with respect to initial conditions and also on coefficients. As corollaries of ...
