# Operations research Operations research applies mathematical modeling, [[Mathematical_optimization|optimization]], simulation, queueing, and decision analysis to improve complex managerial and logistical systems. Linear/integer programming, dynamic programming, stochastic models, and analytics yield optimal or near-optimal policies under resource constraints. <!-- LEGACYSIM:BEGIN v1.5 — generated by g03_mint_wave.py; three.js first; do not hand-edit inside --> ## Microsims (promoted from legacy — three.js first) ### MicroSim spec ### Parameters (tunable controls) - `Resource budget` · 0–100 · total capacity to allocate across tasks - `Demand A` · 0–100 · competing requirement of option A - `Demand B` · 0–100 · competing requirement of option B ### What animates Allocation bars shift to maximize an objective as the budget is split across demands. ### Learning objective Show how a limited resource is optimally allocated across competing demands. <!-- LEGACYSIM:END --> ## Reveal %%REVEAL:d3%% %%REVEAL:svg%% --- *Concept aligned with [Wikipedia](https://en.wikipedia.org/wiki/Operations_research); adapted text, where present, is licensed [CC BY-SA 4.0](https://creativecommons.org/licenses/by-sa/4.0/).* ## Overview Wartime radar rooms made a discipline of [[Mathematics|mathematics]] applied to operations; peace kept it for logistics, scheduling, and service systems, alongside [[Statistics|statistics]] and the machinery of [[Computer_science|computer science]]. Networks and flows come from [[Graph_theory|graph theory]]; strategy from [[Game_theory|game theory]] and [[Decision_theory|decision theory]]; uncertainty from the [[Monte_Carlo_method|Monte Carlo method]]; dependability from [[Reliability_engineering|reliability engineering]]. The field is one of the working arms of [[Systems_science|systems science]]: sibling to [[Systems_engineering|systems engineering]] and [[Systems_theory|systems theory]], sharing regulation ideas with [[Cybernetics|cybernetics]] and [[Control_theory|control theory]] and behavior-over-time modeling with [[System_dynamics|system dynamics]] in the [[Jay_Wright_Forrester|Forrester]] line, and increasingly braided with [[Artificial_intelligence|artificial intelligence]], the [[Neural_network_(machine_learning)|neural network]], and [[Multi-agent_system|multi-agent]] optimization inside [[Economics|economics]] and industry. ## Wikipedia : Wikitube **Strict pair:** [Wikipedia](https://en.wikipedia.org/wiki/Operations_research) : [Wikitube](https://en.wikitube.io/wiki/Operations_research) ## Previous hub tags Hubs: `Systems`.
