decision time Decision making is an important aspect of the Paper F5 syllabus‚ and questions on this topic will be common. The range of possible questions is considerable‚ but this article will focus on only one: linear programming. The ideas presented in this article are based on a simple example. Suppose a profit-seeking firm has two constraints: labour‚ limited to 16‚000 hours‚ and materials‚ limited to 15‚000kg. The firm manufactures and sells two products‚ X and Y. To make X‚ the firm uses

1. Introduction Linear programming (LP) model is a significant and popular used model of operational research technique. It helps to optimize the objective value with constraints. LP model have three essential assumptions when use this model to solve problem. Firstly‚ proportionality and additively‚ which means that the objective function and the functions in constraints are all linear. In other words‚ it means the equation of objective and constraints are linear equation. Secondly‚ LP model
