Modeling and simulation of the quality’s entropy

The aim of the present study is to define quality entropy as well as to illustrate some of its properties. The simulation of the mathematical model for quality entropy shall be performed by means of specialized software for mathematical problem simulation, such as Microsoft Excel that we have employed for this particular study. Our aim is to prove that quality entropy may be expanded to the notions of Markov source of quality and Bernoulli source of quality, by analogy with the Markov and Bernoulli sources employed in information theory. Likewise, the present study delineates some aspects regarding tolerance to quality entropy. The subject of entropy and its application of the management of quality has been approached by other authors as well (Dinu and Vodă, Revista Calitatea-acces la succes, anul 8(4): 60–61, 2007 ; Dinu, Revista Calitatea-acces la succes, anul 8(5): 62–63, 2007 ; Georgescu-Roegen, Legea Entropiei şi Procesul Economic, 1979 ; Stamatiu, Proceedings of the 7th International Conference on Quality, Reability and Maintainabilty, 2000 ; Stamatiu, Proceeding of the 18th International Conference on Quality, Reliability and Maintainability, 2002 ). Through our transdisciplinary approach, we would like to contribute to the development of this subject.
