Abstract: “Soft In manufacturing industry, complexities will often arise due to the presence of a large number of interacting variables and many of which may defy quantification. Nevertheless, engineers use different skills and strategies for accomplishing and resolving the constraints and achieving the tasks. Operations research (OR) is a widely used technique for management problems through different and appropriate mathematical models. One of the widely used tools of operations research in engineering is the linear programming technique. In this technique all the information pertaining to the problem is expressed in terms of linear constraints on the decision variables. Where the data is precise and the constraints are internally controlled, the technique is good for arriving at the optimized decision. Manufacturing industry is often plagued by uncertainties because of unforeseen factors such as changing weather, break-down of equipment, labor in efficiency, and lack of coordination. Uncertain”
