DESCRIPTION
BUSINESS SOLUTIONS
LINEAR PROGRAMMING -- SIMPLEX AND INTERIOR POINT: The simplex method
for solving linear programming problems is an iterative procedure for
finding an optimal solution. The simplex method searches for an
optimal solution among the basic feasible solutions or vertices of a
polyhedron defining a feasible region (collection of points that
satisfy the constraints).
For Release 2, OSL uses decomposition techniques to improve
performance on some problems. A new subroutine allows OSL to take
advantage of the special structure of the problem in the constraint
matrix.
While the simplex algorithm searches for the optimal solution
among the vertices of the feasible polyhedron, the interior point
method searches for a solution by starting in the interior of the
feasible region and working toward the surface.
OSL Release 1 contains an interior-point and a simplex
algorithm for solving linear programming problems. The particular
interior point algorithm used in Release 1 is the primal barrier
method.
A primal-dual barrier method with a predictor-corrector
approach is included in OSL Release 2. This gives the user more
flexibility to select the method that works better with each problem.
OSL now provides linear programming sensitivity analysis and
linear programming parametrics that can be used to analyze the
effects of the model assumptions on the linear programming problem
solution. Using the capabilities, a range of alternatives can be
considered in one operation.
QUADRATIC PROGRAMMING: Quadratic programming problems solved by OSL
have a convex quadratic objective function and linear constraints and
also a subroutine for solving parametric quadratic problems.
MIXED INTEGER PROGRAMMING: OSL will also solve mixed integer
programming problems; i.e., linear programming problems where some of
the variables are constrained to be integers. For Release 2, there
are algorithmic improvements and an additional way of loading the
problem. The basic algorithm is improved by attempting to reduce the
size of the feasible region initially, by taking more action at some
individual nodes and by allowing the user to provide information that
allows OSL Release 2 to solve most problems faster than Release 1.
The new capabilities enhance the usability of the mixed-integer
programming method and improve performance.
PURE NETWORK SOLVER: Network programming problems are linear
programming problems that optimize the transmission of resources
through a network of available traffic routes. The resources, for
example, can be grain, water, trucks, people or money. Network
programming problems are often subproblems of a larger application.
The network simplex method uses the graphical nature of each basis.
Using OSL's pure network programming solver will improve performance
over the simplex solver for network programming problems. This is a
new item in Release 2.
OSL SOLUTION ECONOMIES: Provides sophisticated methods for preparing
a problem prior to submission for solution by producing a starting
basis quickly, reducing problem size by eliminating redundant
constraints and scaling the coefficient matrix.
USER PRODUCTIVITY, GROWTH ENABLEMENT
In addition to the capabilities outlined under Business Solutions,
user productivity is enhanced and system growth is enabled with the
following features.
ACCEPTANCE OF MPS FORMAT: OSL can accept data in MPS input format,
an industry standard since it was introduced by IBM's MPS (and later,
MPSX) product in the 1960s.
OSL UTILITIES: Allows the user to alter matrices, vary printing of
information, write tailored user exits, in an effort to provide
flexibility and productivity.
MULTIPLE PLATFORM SUPPORT: OSL runs under MVS, VM, AIX/370, AIS PS/2
and AIX/6000. It supports the following hardware: ES/9000 and
ES/3090 (TM), with and without vector facility, 43xx, 9370, PS/2
(Models 70 and 80) and RISC System/6000.
(TM) Trademark of International Business Machines Corporation.
MULTIPLE LANGUAGE CALLABILITY: OSL is callable from FORTRAN, C,
PL/I, and APL2 on operating systems where intercallability of these
languages is supported. On the AIX PS/2 platform OSL is callable
only from FORTRAN and C.
HOST-TO-WORKSTATION DOWNLOAD CAPABILITY: The OSL customer may choose
an OSL (on the workstation) feature that will allow the downloading
of a file containing OSL workstation executable code residing on a
host system to host-attached target workstations.
DETAILED RETURN CODE SCHEME: Assists the user with problem
identification, allowing the user to write fault-tolerant driver
programs.
EDUCATION SUPPORT
OSL Release 2 for MVS, VM and AIX/370 education will be
provided by the Engineering and Scientific National Support Center in
Dallas, TX. The classes will be scheduled after availability. Class
schedules will be available on HONE. If access to HONE is not
possible, contact your IBM representative.
SCHEDULE
The planned availability date is July 26, 1991.
