Subject Overview: The Optimization Logic
Industrial Engineering is the study of optimizing complex processes, systems, or organizations. In GATE ME, it is considered one of the most scoring and straightforward subjects, contributing 6–8 marks. It primarily assesses your ability to use mathematical models for inventory control, forecasting, scheduling, and resource allocation.
| Topic | Expected Marks | Difficulty | Frequency |

Pro-Tip: The 'Float' Shortcut
Remember that the Free Float of an activity can never exceed its Total Float. If you find $FF > TF$ in your calculation, you've made a sign error! This simple check is a lifecycle-saver for project network questions.
Logic: EOQ Efficiency
In the basic EOQ model, the minimum total cost occurs exactly when the Ordering Cost equals the Holding Cost.
$$ \text{Ordering Cost} = \text{Holding Cost} \implies \text{Optimal Quantity } Q^* $$
