Abstract
Every mathematician, industrial engineer, computer scientist or management scientist has at some point in their career been asked to solve a problem for optimization, i.e., achieve the best suitable solution under a set of conditions. Finding the right solution is the task at hand; however, selecting the method best suited to achieve an optimal solution is a concealed hard skill necessary for the resulting solution. Operations research (O.R.) methods cover several methods for the purpose of optimization, and extensive research has proved many more novel methods are being proposed every day. Thus, it is challenging to be aware of all possible methods and select the one most suitable to your problem. Here, we will share some guidelines to arrive at the best suited macroscopic method and then leave it to the reader to identify the most suitable method within.
