The Desirability Index (DI) is a widely used method for multicriteria optimization in industrial quality control, by which optimal levels of the process influencing factors are determined in order to archieve maximum process quality. In practice however situations may occur in which slight...

The Desirability Index (DI) is a method for multicriteria optimization in industrial quality control. By design of experiment methods and transferring the multivariate into a univariate optimization problem settings of influence factors are selected that lead to a process with simultaneously...

Pareto-Optimality and the Desirability Index are methods for multicriteria optimization in quality management. In this paper the pareto-optimality of the optimal influence factor settings of a process resulting from maximizing the DI is analyzed and is shown to be valid in most cases.

This paper analyses simultaneous regulation of cost and quality when firms have private, correlated information about productivity and the regulator receives a signal about quality. It is shown that managerial effort and expenditures on quality are positively correlated in the optimal contract....

This article deals with the issue of entry into an industry where firms share a collective reputation. First, we show that free entry is not socially optimal; there is a need for regulation through the imposition of a minimum quality standard. Second, we argue that a minimum quality standard can...
