LPAFIT, An Interactive Linear Programming Package Developed at the Air Force Institute of Technology

摘要

This thesis effort produced a linear programming package, called LPAFIT. Two Fortran programs were written. The first, LPSOLVE, solves linear programming problems using the simplex method. It allows a user to do interactive sensitivity analyses. The second program, LPFRONT, is a preprocessor for LPSOLVE. LPFRONT assists the user in creating the input for LPSOLVE. A procedure controls all file manipulations. The only thing the user must be able to do is to express a problem in terms of a constrained objective function. Both programs are currently formatted to process up to 99 decision variables and 99 constraints. The routines will not solve integer or mixed integer problems. The package runs on a CDC 6600. (Author)
