EZMod Brings the Power of Your Solver
to Your Preferred Programming Environment

MODELLIUM INC. is pleased to introduce EZMod, an efficient and easy-to-use toolkit for designing and developing:

• Optimization Modules as an integrated part of end-user applications.

• Optimization based Decision Support Systems (DSS).

• Mathematical Programming based Software.

• Optimization Modules to support academic research and programs.

EZMod provides a totally transparent and easy access to a wide range of commercial solvers (currently CPLEX, FRONTLINE SYSTEMS and XPRESS-MP). Other popular solvers will be added to the list soon. The modeling and design efforts are solver independent, for EZMod takes care of all the interactions required by the solver.

Specifically designed for Windows 95/98-NT, EZMod 2.0 offers you all the means to work within your preferred programming environment. You can use Microsoft Visual Basic, Delphi, Microsoft Visual C++, Borland C++ Builder or any development environment that allows to call Windows DLLs. This enables you to design and develop the most advanced mathematical programming based programs within short periods of time.

EZMod is a large callable library also available as ActiveX for modeling and solving linear and quadratic optimization problems with continuous and integer variables featuring:

• An innovative and flexible way to describe and manipulate problems, to solve them and access their results;

• A reduction in development effort, cost and time for optimization modules in your applications; 

• A spectacular multisolver application programming interface that allows to call other solvers such as CPLEX, FRONTLINE SYSTEMS and XPRESS-MP from within the same application;

• A transparent interfacing to solvers such as CPLEX, FRONTLINE SYSTEMS or XPRESS-MP, thus enlarging the scope of problems they can handle. You will be able to solve Quadratic Mixed Integer Programming (QMIP) problems even if your solver does not support it; 

• An access from your preferred programming environment, Microsoft Visual Basic, Delphi, Microsoft Visual C or Borland C/C++; 

• A Description of problems in the order dictated by your application logic and not that of your solver;
   

How EZMod Describes the Optimization Problems (DLL version):

This generic form is a:

• linear program (LP) if the Q matrix is null and X contains only continuous variables;
  
• quadratic program (QP) if the Q matrix is not null and X contains only continuous variables;
  
• mixed integer program (MIP) if the Q matrix is null and X contains at least one integer variable;
  
• quadratic mixed integer program (QMIP) if the Q matrix is not null and X contains at least one integer variable;

EZMod enables you to model and solve LP, QP, MIP and QMIP programs either with your own solver (CPLEX, FRONTLINE SYSTEMS, XPRESS-MP) or with EZMod-Solver.

QMIP problems are solved even if your solver does not support it.
