Operations research (OR) involve finding solutions for problems with the help of analytical methods. It finds application in decision making processes in different organizations. Solutions are arrived at by breaking down the problems into fundamental components and by applying mathematical analysis in definite steps.

The tools used to solve the problems

The different mathematical tools applied to find solutions to problems involve linear programming, network optimization, and queuing theory. In addition to this, game theory and simulation can also be used to find solutions.

The process of arriving at a solution

In the process of solving the problem, many possible alternatives are developed. There may be many potential solutions. The possible solutions that are developed will be analyzed and  few of them which are most likely to be feasible are adopted. The short listed solutions are then simulated and tested in real life conditions to determine the best possible solution.

Daily life applications

In our daily life problems, operations research can be used to arrive at solutions. Let us take the case of determining the best possible option to reach office. With the help of network optimization we can easily arrive at the best solution out of the available options.

Now let us consider the packing of a bag before a trip. We can use heuristics method, where the big clothes are placed first and then small things are used to fill the gaps. This will help us to reduce the size of the bag that we need to carry.

In the case of preparing for a marriage function, we can make use of Gantt charts to schedule the various activities to be completed. We can divide the days remaining and allocate time to complete specific activities such as inviting relatives, purchase, reserving the auditorium, making arrangements for the reception etc. The Gantt chart can be used in many other occasions such as preparing for examinations, interviews etc.

Another instance when operations research can be used is the buffet event. We can make use of the queuing theory and arrange the table in such a way that guests can take food from both the sides. This will reduce the waiting time by half.

Thus different methods associated with operations research can be used in our daily life situations to find the optimal solution without incurring much expense. It reduces cost, effort, time and energy in finding solutions with conventional methods.
