Key Topics for Preparation

Productivity & Work Study: Taylor’s principles, motion and time study.

Plant Layout & Material Handling: Layout types, selection principles, symptoms of bad layout.

Group Technology & Process Planning: Cell formation, coding, advantages.

Production Planning and Control (PPC): Functions, scheduling, routing, dispatching.

Inventory Control: EOQ, ABC analysis, JIT, MRP.

Forecasting & Simulation: Role in production systems.

Transportation & Assignment Models: VAM, MODI, optimization.

Queuing Theory: Poisson arrivals, exponential service, average queue length & waiting time.

PERT & CPM: Network construction, critical path identification.

Study Tips

Practice numerical problems on transportation, queuing, and inventory control.

Revise key definitions — productivity, ergonomics, MRP, JIT, PPC, etc.

Draw clear diagrams — process layouts, PERT/CPM networks, ABC curve.

Understand formulas for queue theory and EOQ.

Focus on applications of industrial engineering tools in productivity improvement.
