1997 journal article
A methodology for the reduction of imprecision in the engineering process
EUROPEAN JOURNAL OF OPERATIONAL RESEARCH, 100(2), 277–292.
author keywords: engineering design; design; decision making; constraint processing; fuzzy set theory; hierarchical modeling; concurrent engineering; precision convergence; coefficient of imprecision
TL;DR:
A hierarchy of fuzzy constraint networks is presented along with a methodology for creating transitional links between different levels of the hierarchy, and a new measure introduced to quantify imprecision is measured.

1997 journal article
A parametric representation of fuzzy numbers and their arithmetic operators
FUZZY SETS AND SYSTEMS, 91(2), 185–202.
author keywords: fuzzy arithmetic; triangular fuzzy numbers; membership functions; arithmetic approximations
TL;DR:
This work provides the methods for performing fuzzy arithmetic and shows that the PFN representation is closed under the arithmetic operations, and proposes six parameters which define parameterized fuzzy numbers (PFN), of which TFNs are a special case.

1997 journal article
Analysis of the error in the standard approximation used for multiplication of triangular and trapezoidal fuzzy numbers and the development of a new approximation
FUZZY SETS AND SYSTEMS, 91(1), 1–13.
author keywords: fuzzy arithmetic; triangular fuzzy numbers; trapezoidal fuzzy numbers; membership functions; computational complexity; multiplication; product operator; multiplication approximation
TL;DR:
The error of approximation for repeated use of the multiplication operand is examined and it is shown it can be sufficiently large in simple circumstances to produce erroneous results.
