Operations Research can be defined as the use of quantitative methods to assist analysts and decision-makers in designing, analyzing, and improving the performance or operation of systems. The field of Operations Research incorporates analytical tools from many different disciplines, which can be applied in a rational way to help decision-makers solve problems and control the operations of systems and organizations in the most practical or advantageous way. Central to the practice of Operations Research is the process of building mathematical models. Experience in modeling reveals that, although quantitative models are based on mathematical truths and logically valid processes and such models may command the respect of management, solutions to mathematical problems are typically interpreted and implemented under a variety of compromising influences. Contributing to the imperfection in our problem-solving endeavors is the use of automatic computing devices to assist in the calculations. The exact representation of real numbers requires the use of an arbitrarily large number of binary digits.
