Operations Research for Managers - Unit 1

Introduction to Operations Research

• Operations Research (OR) is a methodical approach for decision-making and problem-solving in organizations.
• It utilizes mathematical and scientific techniques to evaluate alternative actions and their consequences.

Definition and Characteristics of OR

• OR aims to optimize man-machine systems under resource constraints.
• Key characteristics include its scientific method application, multidisciplinary approach, and focus on optimal solutions.

Scope of Operations Research

• Industrial Management:
  • Involves production, product mix, inventory control, demand forecasting, sales and purchase optimization, transportation, and maintenance.
• Defense Operations:
  • Applied in army, air force, and navy operations including intelligence and training.
• Economics:
  • Focuses on maximizing per capita income and addressing poverty and hunger.
• Agriculture:
  • Involves optimal land allocation for crops and water distribution management.
• Other Areas:
  • Includes applications in hospitals, transportation, and life insurance.

Limitations of Operations Research

• Mathematical models often ignore qualitative and emotional factors.
• Models are suitable for specific problem categories only.
• Resistance to OR methods due to conventional management thinking and employee apprehension.
• OR should complement human decisions rather than dictate them.

Applications of Operations Research

• Allocation and Distribution:
  • Optimizes resource allocation including manpower, materials, and finances.
  • Focuses on project scheduling, monitoring, and control.
• Production and Facilities Planning:
  • Determines factory location, facility requirements, inventory forecasting, and economic order quantities.
  • Enhances scheduling and machinery allocation for production runs.
  • Involves decisions on transportation and warehouse location, as well as maintenance policies.
• Program Decision Making:
  • Streamlines procurement processes to minimize costs.
  • Includes strategies for bidding and replacement policies.
