Tg. Pham et N. Turkkan, THE LORENZ AND THE SCALED TOTAL-TIME-ON-TEST TRANSFORM CURVES - A UNIFIED APPROACH, IEEE transactions on reliability, 43(1), 1994, pp. 76-84
The strong relationship between the Lorenz and Scaled Total Time-On-Te
st transform curves allows measures devised separately for the fields
of economics & reliability to be applied to the other field as well. T
his article shows that, more accurately, the Gini-index and Pietra-rat
io can be useful in reliability analysis and that several other questi
ons remain to be explored. Associated graphical methods can be very us
eful within an integrated approach. A user-friendly computer software
developed by the authors is useful to theoreticians & practitioners al
ike.
