JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD B.Tech III INTRODUCTION TO INDUSTRIAL ENGINEERING Previous Question Paper (September - 2021 - R18)

Industrial Engineering is the branch of engineering concerned with the design, improvement, and installation of integrated systems of people, materials, information, equipment, and energy. It draws upon specialized knowledge and skill in the mathematical, physical, and social sciences, together with the principles and methods of engineering analysis and design, to specify, predict, and evaluate the results to be obtained from such systems.

The primary objectives include:

• Increasing productivity and efficiency of operations.
• Reducing production costs and eliminating waste.
• Improving quality control and reliability of products.
• Ensuring safety and ergonomic well-being of the workforce.
• Optimizing resource utilization and supply chain performance.

Key activities involve:

• Work Measurement and Method Study: Analyzing tasks to standardize procedures and set time standards.
• Facility Planning: Designing plant layouts and material handling systems.
• Production Planning and Control: Scheduling and managing flow of materials and production activities.
• Quality Engineering: Implementing statistical process control and continuous improvement programs.

Industrial engineering utilizes various analytical and quantitative tools to support managerial decision-making and problem-solving:

• Operations Research (OR): Uses mathematical modeling, such as linear programming and queuing theory, to optimize resource allocation and minimize costs.
• Statistical Quality Control (SQC): Employs control charts and sampling techniques to monitor process variability and ensure product quality standards.
• Work Study (Method Study and Time Study): Provides a systematic approach to analyze work processes, eliminate redundant motions, and establish standard times for tasks.
• Simulation: Uses computer models to replicate complex real-world systems, allowing managers to test 'what-if' scenarios without disrupting actual operations.
• Ergonomics and Human Factors: Applies physiological and psychological data to design workstations and tools that enhance worker performance and reduce fatigue.
• Project Management Tools: Techniques like PERT (Program Evaluation and Review Technique) and CPM (Critical Path Method) are used for planning, scheduling, and controlling complex projects.
• Value Engineering: A systematic method to improve the 'value' of goods or products by examining the function of each item or component.
