GATE 2023 Production and Industrial Engineering Exam Pattern, Marking Scheme and Weightage of Topics

Why is Knowledge of Exam Pattern important?

A large percentage of students take admission in engineering colleges especially in India. Therefore these examinations are earmarked for cut throat competition among aspirants to excel. A student should have complete knowledge about not only the syllabus but also exam pattern and marking scheme that is followed. 

By focusing on the syllabus the student must create a study schedule or timetable that they should ardently follow. This will help them to be prepared for their upcoming exams. It will also allow students to have a better understanding of the examination and what it expects from the test-takers. In this day of age, it is pivotal to “study smarter than study harder”. Referring to GATE previous year question papers are one of the effective methods for preparation.

What is Production & Industrial Engineering and its Scope?

Production Engineering is a specialized field of Mechanical Engineering. The objective of this is to enable engineers to enhance their effectiveness and efficiency of manufacturing and service sector industries. The curriculum includes basic mechanical engineering subjects such as engineering mechanics, machine design, heat transfer, thermodynamics, the strength of material, etc. 

The course makes graduates appropriate with the existing and emerging needs of the industry. B.E. or B.Tech in Industrial and Production Engineering is a four-year programme. Those who have pursued these courses would understand existing technological trends and help to add new technology to the existing system.

Scope of Production & Industrial Engineering 

• Industrial and production engineers use principles of engineering, mass production and technology to help organizations find ways to offer services or manufacture a product efficiently. Check GATE PSU Recruitment 
• The Industrial Engineers work to improve the product through better management and quality control. 
• One can pursue M.Tech in Industrial and production Engineering after successful completion of B.Tech/B.E. 
• The job profiles available for Industrial and production engineers are tabulated below:
