dc.description A dissertation submitted to the Department of Mathematics for the MSc in Operational Research en_US
dc.description.abstract Operational Research (OR) is the use of advanced analytical techniques to improve decision making. OR is sense to make the best use of available resources. OR consistently delivers significant value strategic to tactical, top-line to bottom-line to the organizations and executives who use it. Organizations worldwide in business. the military, health care, and the public sector are realizing powerful benefits from Operational Research//Basically, OR models contained hard mathematical calculations such as matrices. differentiations, integrations, calculus, Lagrangian multipliers with very complex formulas. To find solutions for selected OR model, needed to memorized the final formulas or needed to have a good OR, Mathematical and Statistical theory background in order to derive final formulas. However, to achieve the final solutions, wants to passed lots of calculations and also it might take more time. It has to be carefully worked with numerical calculations to reached accurate answers in short time period, for handle the final decision. Therefore, to find accuracy solutions for selected OR model in short time period without having any theoretical background, it is important to have software.//There is a few number of Computerized Operational Research Applications are available; Such as Windows based TORA, Excel Spreadsheet templates, LINGO,QM and AMPL applications. By considering, OR models, there were no options to solve Inventory Control and Replacement & Maintenance models by using a software. Studying, Inventory Control and Replacement & Maintenance techniques and identified the requirements in each model//Designed software based on structured system analysis design method. To implemented, Microsoft Visual C++ 6.0 is a textual language used to create the required system. Test the models to verify the accuracy for each possibility with actual expected answer and computerized answer//The main advantage of this software is, user doesn't need to worry about the mathematical and statistical calculations and can be saved time and energy. en_US
