Reliability‐based analysis of service recovery

Simons, Jacob V. - In: International Journal of Quality & Reliability Management 21 (2004) 1, pp. 11-31

To succeed, service businesses must offer their customers high‐quality, reliable service. However, many of the characteristics that make services unique also make it difficult to ensure consistently correct performance. To promptly identify and correct errors when they occur, service managers...

Approximate self-affine model for cultivated soil roughness

Yordanov, O.I.; Guissard, A. - In: Physica A: Statistical Mechanics and its Applications 238 (1997) 1, pp. 49-65

We consider laser profiler measured soil profiles and show that the roughness of the cultivated soil can be viewed as an approximately self-affine structure. This conclusion is drawn from the limited range scaling behaviour found in both the variance and the second-order structure function of...

Algorithms for symbolic reduction of signal flow graphs

Szymkat, Maciej - In: Mathematics and Computers in Simulation (MATCOM) 42 (1996) 4, pp. 675-684

In this paper certain properties of algorithms used in symbolic manipulation on signal flow graphs are investigated. The rule-based approach and Mason's formula are compared with respect to preservation of minimal rational representation. It is shown by counter example that rule-based method...

INDIGENOUS KNOWLEDGE AS A STRATEGIC RESOURCE: AN ETHICAL AND SOCIETAL CHALLENGE

Lengnick-Hall, Cynthia A. - College of Business, University of Texas-San Antonio

Organizations, particularly large multinational firms, have a substantial impact on the economies and societies in which they operate. Unfortunately some far-reaching influences are not anticipated, and, the consequences of these organizational actions can create long-term, adverse outcomes....
