A nonlinear (nonconvex) programming model provides a new definition of efficiency for use in evaluating activities of not-for-profit entities participating in public programs. A scalar measure of the efficiency of each participating unit is thereby provided, along with methods for objectively determining weights by reference to the observational data for(More)

The methods and al,orithms used for optimizina the aJlcx:ation of transportalton capability are also used for many other Steminal)' unrelated problems of allocation and allotment. Because of this wide range,of(More)
Ex = (I + y / t) (l +. r y / : ') El0 = (1 + ! / / Z) (l + .r2y/:3) all R-multiples of Es. The error positions in this case are (j. 1. l) , In general, when decoding an error relative to an algebraic geometric code C*(D. 7rtP), there is a vector space S (g) l of error-locator functions of dimension Z(m)-e. Most algorithms settle for any element of this(More)

This paper presents Data Envelopment Analysis (DEA) has been used in a wide variety of applied research and it is a linear programming methodology that has been widely used to evaluate the performance of a set of decision-making units (DMUs). It requires crisp input and output data. However, in reality input and output cannot be measured in a precise(More)
