Several software systems are available for implementing automatic differentiation of computer programs. The forward mode of automatic differentiation is limited by computational intensity and computer memory. The reverse mode, or adjoint approach, is

GRESS uses a precompiler to interpret FORTRAN statements and determine the mathematical operations embodied in them. As each arithmetic assignment statement in a program is interpreted, information necessary to allow the calculation of derivatives is

A world oil market model (WOM) with OPEC treated as a Stackelberg cartel has been developed within the framework of the Generalized Equilibrium Modeling System (GEMS) that is available from Decision Focus, Inc. The U.S. sector of the model is represe

This paper discusses a nonlinear equation theory of sensitivity analysis and demonstrates its applicability to a large energy-economics model by applying it to a specific calculation carried out with the Long-Term Energy Analysis Program (LEAP). It p
This paper presents the development of a FORTRAN compiler and an associated supporting software library called ADGEN. ADGEN reads FORTRAN models as input and produces and enhanced version of the input model. The enhanced version reproduces the origin

Adjoint sensitivity theory can be used to determine the sensitivity of results of interest to each of the data elements that enter into the calculations. In this paper adjoint sensitivity theory is discussed, and its applicability to a large energy-e
