This problem‚ as outlined above‚ is an example of a linear programming problem. Linear programming is part of the Optimization Techniques field of Mathematics‚ used for resource allocation and organization. With linear programming problems‚ one takes the inequalities that exist within a given situation and deduces a best case scenario under those particular conditions (Stapel‚ 2009). One particularly effective method of solving linear programming problems is the Simplex Method. The Simplex Method

INTRODUCTION My topic is oil refinering using linear programming‚ this is under petrochemical industries which mean it will deal more about chemicals‚ this is about optimising the cost using a modelling method in mathematics called linear programming. This is very important because it links what is done in petrochemical industries with mathematics. Since there is a huge need of the products that are produced after petroleum refinering which are petrol‚ gasoline‚ oil‚ diesel and etc so in the
