Linear Programming Concept Paper There are two types of linear programming: 1. Linear Programming- involves no more than 2 variables‚ linear programming problems can be structured to minimize costs as well as maximize profits. Due to the increasing complexity of business organizations‚ the role of the management executive as a decision maker is becoming more and more difficult. Linear programming is a useful technique to solve such problems. The necessary condition is that the data must be

Linear Model[edit] It is a one way model to communicate with others. It consists of the sender encoding a message and channeling it to the receiver in the presence of noise. In this model there is no feedback which may allow for a continuous exchange of information. This form of communication is a one-way form of communication that does not involve any feedback or response‚ and noise. (F.N.S. Palma‚ 1993‚ Shannon and Weaver[edit] The new model was designed to mirror the functioning of radio and telephone
