Development of Software for Solving Refinery Blending Problems using Visual Studio

This work is aimed at developing a software that could be used to solve Refinery blending problem using Visual Studio. The software was developed from visual studio 2020 through visual basic for solving quadratic programming problems which reduced to revised simplex method for linear programming when the objective function is linear. The result shows that the software can perform the same function with Mat lab and Excel Solver, which implied that the software development is consistent with Excel solver applications. It provides the same solution with Mat lab. Also, it is very flexible and easy to operate. The software can optimize 20x20 Matrix while Mat lab solves 15x15 Matrix. Comparison on tested problems indicated that the software is more efficient than Excel Solver and Matlab 7.0.
