use Excel spreadsheet modeling and Solver to find the optimal solution of optimization problems. If the model has two variables‚ the graphical method can be used to solve the model. Very few real world problems involve only two variables. For problems with more than two variables‚ we need to use complex techniques and tedious calculations to find the optimal solution. The spreadsheet and solver approach makes solving optimization problems a fairly simple task and it is more useful for students who

to Programming Prof. Mazen Alkhatib7 January 2014 Similarities between Procedural Programming and Object Oriented Programming Procedure Programming and Object Oriented Programming both break down program tasks. Procedure Programming and Object Oriented Programming both uses linear sequence of commands‚ yet Object Oriented Programming have developed a more complex and abstract approach (Stetson‚ 2004). Object Oriented Program is an extension to Procedure Program. Procedure Programming and
