A QUALITY CONTROL MODEL FOR COMPLEX ITEMS
Abstract
A formulation and analysis is presented of a mathematical model which is useful in resolving certain problems associated with the maintainance of suitable quality levels in the production of complex items. Consider an item composed of many interrelated component parts. These parts are subject to random fluctuations in performance and to random environmental influences so that there is some definite probability less than one (over) that a given item will conform to performance specifications on any given trial. A method is presented for constructing a large class of consistent asymptotically normal efficient estimates for the parameters of distributions satisfying certain regularity conditions. Another aspect considered is the problem of optimum allocation of k (the number of observations per item). Tables are presented which give the minimizing value of k for certain pairs of positive real parameter points. Asymptotic expressions for the minimizing value of k are also presented. (Author)
