Key Topics to Revise
Basic Concepts and Components of LPP
- Linear Programming deals with optimization of a linear objective function subject to linear constraints
- Three main components: Decision Variables, Objective Function, and Linear Constraints
- Decision variables represent quantities to be determined (usually x, y)
Types of LPP and Real-Life Applications
- Manufacturing Problem: Optimizing production with limited resources
- Diet Problem: Finding minimum cost diet satisfying nutritional requirements
- Transportation Problem: Minimizing transportation cost from sources to destinations
Solution Concepts and Terminology
- Solution: Set of values satisfying constraints
- Feasible Solution: Solution satisfying all constraints including non-negativity
- Infeasible Solution: Solution violating one or more constraints
Fundamental Theorems of Linear Programming
- Theorem 1: Optimal value occurs at corner point of feasible region
- Theorem 2: For bounded region - both max and min exist at corner points
- For unbounded region - max/min may not exist, but if exists, occurs at corner point
