In operational research methods, the variables must be quantifiable in numeric terms. If you identify and quantify the contributory parameters of the variables involved, along with their resource or other relevant limitations, you can use linear programming techniques.

Also, if you apply different processes to complete a project, it can be broken down into different activities. This allows you to implement network analysis to determine the duration and cost of project completion, based on the application of resources.

There are other possible techniques useful in operational research, like determining Economic Order Quantity, depending on how your processes have been implemented with their inter-dependency.

Hope this will help you; and GL with your study.
