1.3.1 Process Design and Optimization

1. Process Design and Optimization It is the systematic effort to analyze existing workflows and design new, highly efficient systems to maximize output while minimizing inputs and waste. 2. The Goal The primary aim is continuous improvement in three main areas: Reduce Waste (Muda): Eliminating non-value-added activities (e.g., waiting, excessive motion, defects, unnecessary inventory). Increase Productivity: Maximizing the ratio of Output / Input (e.g., more units produced with the same or fewer hours of labor and materials). Enhance Quality: Building quality into the process so that products/services are right the first time. 3. DMAIC Cycle (Six Sigma Methodology) The DMAIC cycle is a structured, data-driven approach used in process improvement and optimization to reduce defects and improve quality. D – Define Clearly define the problem , project goals, and customer requirements. Identify process boundaries , stakeholders, and critical-to-quality (CTQ) factors. ...

OIE -357 - INTRODUCTION TO INDUSTRIAL ENGG - TWO MARK QUESTIONS WITH ANSWERS

UNIT I – INTRODUCTION TO INDUSTRIAL ENGINEERING Industrial Engineering Industrial Engineering is concerned with the design, improvement, and installation of integrated systems of men, materials, machines, and methods. Father of Scientific Management F.W. Taylor is known as the Father of Scientific Management. Productivity Productivity is the ratio of output produced to the input used in the production process. Objectives of Industrial Engineering To increase productivity and reduce waste by efficient utilization of resources. Production System A production system is a set of interrelated components that transform inputs into finished outputs. Input–Output Model The input–output model represents the transformation of resources such as men, materials, and machines into finished goods. Applications of Industrial Engineering Industrial Engineering is applied in manufacturing, service industries, healthcare, and logistics. Factors Affecting Productivity ...

1.2.6- Operations Research (OR)

Definition Operations Research (OR) is a scientific and quantitative approach to decision-making that uses mathematical models, statistics, and optimization techniques to find the best possible solution to complex industrial and managerial problems. Objectives of Operations Research To achieve optimal utilization of resources To minimize cost or maximize profit/output To improve decision-making To handle complex problems involving uncertainty and constraints Features of Operations Research Uses mathematical and analytical models System-oriented approach Interdisciplinary in nature Focuses on optimization Data-based and scientific Basic Steps in OR Problem formulation Construction of a mathematical model Collection of relevant data Solution of the model Testing and validation Implementation of results Common OR Techniques Linear Programming (LP) Transportation and Assignment Models Inventory Models Queuin...
