5 self-contained study topics — notes, diagrams, formulas, and worked examples for exams and GATE.
Topics
- Linear ProgrammingLinear programming optimizes a linear objective under linear constraints and non-negativity limits.
- Transportation and Assignment ModelsTransportation and assignment models allocate resources to destinations at minimum total cost.
- Queueing TheoryQueueing theory estimates waiting, congestion, and service performance in stochastic systems.
- Inventory ModelsInventory models choose order size and reorder timing to balance ordering and holding costs.
- Simulation BasicsSimulation imitates real system behaviour when analytical models are difficult or unrealistic.
