Linear Programming (LP) is a mathematical modelling technique useful for economic allocation of 'scarce' or 'limited resources, such as labour, material, machine, time, warehouse space, capital, energy, etc., to several competing activities, such as products, services, jobs, new equipment, projects, etc., on the basis of a given criterion of optimality. The phrase scarce resources means resources that are not in infinite in availability during the planning period. The criterion of optimality, generally is either performance, return on investment, profit, cost, utility, time, distance, etc. The word linear refers to linear relationship among variables in a model. Thus, a given change in one variable will always cause a resulting proportional change in another variable. For example, doubling the investment on a certain project will exactly double the rate of return. The word programming refers to modelling and sol
