Study Notes
Operations Research (OR)
- Operations research (OR) is an applied mathematical field focusing on developing and applying analytical methods to improve decision-making
- OR aims to find optimal or near-optimal solutions to problems using techniques from mathematical sciences (modeling, statistics, optimization)
- OR emphasizes practical application and overlaps with fields like industrial engineering
- OR seeks to determine maximum or minimum extreme values related to a real-world objective (e.g., maximizing profit, minimizing cost)
- OR utilizes various problem-solving techniques including simulation, optimization, queueing theory, Markov decision processes, econometrics, and more.
- OR constructions rely heavily on mathematical models of the system under analysis
- OR is linked to computer science and analytics due to computational and statistical aspects
- Operational researchers adapt techniques based on system characteristics, goals, and available resources (time, computing power)
- Modern OR covers extensive sub-disciplines (e.g., logistics, training scheduling)
Historical Development of OR
- OR origins trace back to military efforts before World War II
- 17th-century mathematicians (Pascal, Huygens) applied game-theoretic concepts.
- 20th-century inventory management studies (e.g., economic order quantity, Ford W. Harris) mark a milestone for modern OR
- Early War I efforts (convoy theory, Lanchester's laws) laid foundations, but modern OR started post WWII.
- Operational research emerged at Bawdsey Research Station (UK) in 1937, focusing on analyzing radar systems
- WWII saw OR defined operationally, with significant contributions from scientists like Blackett.
WWII Operational Research Examples
- Blackett's "Circus" team reduced anti-aircraft rounds for shot-down planes
- Blackett's team at Coastal Command's Operational Research Section analyzed convoy size and escort/submarine effectiveness, suggesting fewer, larger convoys (and white-painted aircraft)
- Blackett's team found optimal depth charge settings
- Bomber Command’s team analyze bombing survey data; recommended armor placement in undamaged areas
- RAF Bomber Command analyses and optimal bomber stream formation to minimize loss
- The "exchange rate" method compared effort and efficiency for resource allocation (e.g., mines & ship, aircraft & U-boat sightings)
- Allied bomb effectiveness in several campaigns
- Increased training ratios for B-29s for on-target bomb rates.
Post-War OR and Management Science
- OR expanded from military to business and society in post-war decades
- OR broadened from operations to new fields like equipment acquisition, training, logistics, and infrastructure
- Management Science (MS) emerged as a related field, using OR models in the business sector
- Development of computer tools increased OR's problem-solving capacity
Organizations and Further Developments
- IFORS (International Federation of Operational Research Societies), IFOS helped to institutionalize OR internationally
- INFORMS (Institute for Operations Research and the Management Sciences) promotes and advances OR through publication of top-tier journals.
- Modern applications range from city planning and football strategy to industry & economic optimization, terrorism and counter-terrorism
- Recent criticism of OR's focus on mathematical models without strong empirical data collection.
Key Concepts In Management Science (MS)
- MS similar to OR, but focuses on business applications
- MS employs similar scientific methods and mathematical models used in OR, but it emphasizes application directly to the business environment
