## Steps to solve Assignment Problems

Assignment steps:1.Make row minima2.Column minimaCheck test of optimalityRule: 1. Cut max zeros with min possible lines2. No of lines = no of rows/columnThen if nt equalStep1 3 element Uncovered, covered and intersecting See uncovered elementIn it select minimum uncovered….Then less than minimum no. From allUncoveredAdd it to all IntersectingAnd Covered elements remain same..Again test of optimalityAssign rules:Only 1 […]

## Steps to solve Test Of Optimality

TEST OF OPTIMALITY 1. Only for Occupied Cellsfind Ui, Vj using Cij =Ui+Vj(Ui pata hai ya Vj? Jo pata hai usko cost m se minus karo)2. Only for unoccupied cellFind Opportunity cost.Δij= cij- (ui+vj)( ye unoccupied hai? Iska Ui kitna hai? iska Vj kitna hai? Total of Ui + Vj?Cost – Total = Δij)If all Δij […]

## Concepts & Steps of Operations Research April 2014 Exam Transportation Problems

Steps – Take Dummy (if required) for balancing the problem & then convert in Regret matrix (if required) if it is a Maximization problem. If there is any Restriction or Prohibition, convert it in M. Find IFS. If the method for IFS is specified in question, use only that method. But if any method is […]

## Concepts & Steps of Operations Research April 2014 Exam Linear Programming Problems

LINEAR PROGRAMMING PROBLEMS {GRAPHICAL METHOD}   TERMINOLOGY OF LP – Decision Variables: The unknowns to be determined. Constraints: Mathematical equations of the limitations imposed by the situation or problem characteristics. Constraints define limits within which the solution of the Problem has to be found. Objective Function: The mathematical equation of the major goal of the […]

## Concepts & Steps of Operations Research April 2014 Exam Assignment Problems

Steps – Take Dummy (if required) & then convert in Regret matrix (if required) Do Row minimization and Column minimization. Cover all Zeroes in the Table with Minimum possible lines. (Start from maximum zeroes, either row-wise or column-wise). If optimal, find assignment. If not optimal, write next table, change values & check again with Minimum […]
