This article throws light upon the four main steps involved in the construction of OR model. The steps are: 1. Selecting Components of the System 2. Pertinence of Components 3. Combining the Components 4. Substituting Symbols. Step # 1. Selecting Components of the System: All the components of the system which contribute towards the effectiveness measure of the system should [...]
This article throws light upon the top three examples on the application of linear programming. Example # 1. Production Allocation Problem: A firm produces three products. These products are processed on three different machines. The time required to manufacture one unit of each of the three products and the daily capacity of the three machines are given in the table [...]
After reading this article you will learn about the graphical method for solution of L.P.P with the help of examples. The graphic solution procedure is method of solving two variable linear programming problems for LPPs that have one two variables, it is possible that the entire set of feasible solution can be displayed graphically by plotting linear constraints on a [...]
After reading this article you will learn about the procedure for crashing the network. The time-cost relationships can be visualized graphically in the form of a time verses cost curve which is for a limited portion at least, sloping downward, as depicted in the following fig. Here it is assumed that for each activity, there is an activity duration for [...]
After reading this article you will learn about the requirement of Linear Programme Problem (L.P.P). Linear programming is an optimization technique for finding an optimal (maximum or minimum) value of a function, called objective function, of several independent variables, the variable being subject to various restrictions expressed as equation or inequalities. The term linear indicates that the function to be [...]
After reading this article you will learn about the degeneracy in L.P problem and method to resolve it. Degeneracy in L.P Problem: Degeneracy is revealed when a basic variable acquires a zero value rather than a negative or positive value. In the final solution, either the number of basic variable is not equal to the number of constraints, or the [...]
This article throws light upon the top two artificial variable techniques for solving L.P.P. The techniques are: 1. The Big-M technique. 2. The Two Phase Method. 1. The Big-M Method: This method consists of the following basic steps: Step 1: Express the L.P.P in the standard form. Step 2: Add non-negative artificial variables to the left hand side of all [...]
