Exam tips for Operations research
Dear Students,
The OR Paper consists of 5 chapters divided into 4 major units. The numerical of the following chapters need to be done well
- Graphical LPP- formulation and graphical solution
- Simplex- Minimization method
- Sensitivity (IMP)
- Assignment- Minimization, maximization and restricted route type
- VAM -Transportation (including MODI and degeneracy)
- Decision sciences- tree diagram, EMV, EPPI, EOL
- Maximin, Minimax, Alpha , Laplace and Minimax regret in Decision theory
- CPM- Floats and Forward and backward path computations
- PERT
- Crashing
Â
OR paper would contain 5 questions each of 15 marks. Assignment and transportation would be asked in one main question. The tentative pattern of paper would be as follows
Q1- Graphical LPP, Simplex LPP, 3 small concepts (Solve any 2)
Q2- Transportation, assignment, 3 small concepts (solve any 2)
Q3- CPM, PERT, Crashing (Solve any 2)
Q4- Computation of EPPI,EMV,EOL; Minimax Laplace alpha and Minimax regret; Decision tree (Solve any 2)
Q5- Case study:-Â Â Â Â Â Â Â Â Â Â Â Â Â Â Case study is expected from the following chapters
Transportation (VAM may be solved. MODI and then optimization need to be done)
PERT or Crashing
Sensitivity analysis (Maximization simplex fully or partially solved)- Highly expected
Â
Time management is a key in OR paper.
The following questions need to be done well for theory
- Constraints in LPP
- Infeasibility in Graphical and Simplex
- Redundancy in graphical and simplex
- Iso profit line in graphical
- Degeneracy in simplex
- Slack, surplus and artificial variables in simplex
- Shadow prices in simplex
- Degeneracy in transportation
- Methods of doing transportation sum
- Hungarian method in assignment problem
- Diff between transportation and assignment
- Types of float in CPM
- Critical and sub critical paths
- Objectives of crashing
- Updating
- 3 Time estimate in PERT
- CPM vs PERT
- Decision making under risk and uncertainty
- Decision tree
- Perfect information in decision theory
