Effects-based operations (EBO) • Concept for planning and executing military operations(e.g., Davis, 2001) • Complex military operations, systems perspective • How to produce effects in a system? • Single action produces multiple effects • CONTENTS • Planning of EBO = MCDM problem • Multiple criteria influence diagrams in EBO
Steps in EBO planning System Threateningmilitary buildupin a country • Identify higher level objective • Describe operation as a system • Derive effects from thehigher-level objective • First described qualitatively • Find actions which contribute to the fulfillment of effects • How to measure the fulfillmentof effects? • Criteria • Economic sanctions • Missile strike • Etc. • Public unrest • Etc. Actions Effects
Description of the system Country • Functionally related elements • Elements have states • E.g. works / out of order Element Car factory Dependency Car factory goes out of business if steel mill doesn’t produce steel Element Steel mill
Effects described by one or multiple criteria Criteria defined in terms of system elements Multiple elements related to single criterion Criteria make effects measurable Qualitative modeling Country Car factory Criterion Unemployment Effect Publicunrest Criterion Media coverage
System model Elements = System variables Dependencies between elements Actions : Element states Criteria The EBO problem Planning EBO as an MCDM problem
Planning EBO as an MCDM problem Country System • Economic sanctions • Missile strike • Etc. • Public unrest • Etc. Actions Effects Actions Criteria
Previous literature • Probabilistic modeling (Davis, 2001) • System dynamics (Bakken et al., 2004) • Bayesian networks (Tu et al., 2004) • Single criterion • Combination of Bayesian networks and Petri nets (Wagenhals & Levis, 2002; Haider & Levis, 2007) • Effects over time • Efficient set not determined • Agent-based modeling (Wallenius & Suzic, 2005) • Calculates criteria given an action • Efficient set not determined • Outranking methods (Guitouni et al., 2008) • No system model
Multiple criteria influence diagram (MCID) System • Bayesian network used as a system model • Elements: chance nodes / random variables • Dependencies: arcs /conditional probabilities • MCID (Diehl & Haimes, 2004) • Actions represented by decision nodes • Criteria represented by utility nodes ... ... Actions Criteria
EBOLATOR - Decision support tool • Implementation utilizing MCID • Construction of system model(GeNIe, 2009)
EBOLATOR - Graphical user interface • Visualization of actions • Calculation of efficient set • Criteria weights Single action
EBOLATOR - Sensitivity analysis • Weights • MCID probabilities
EBOLATOR - Example analysis • Defensive air operation • System • Civil and military infrastructure • Actions • Aircraft positioning andair combat tactics • MCID • 12000 probabilities • 729 actions • Analysis • 13 efficient actions • Sensitivity analysis
Conclusions • Multiple criteria and systems perspectiveessential in planning EBO • Similar philosophy applicable in other application areas (e.g., hospital, marketing) • Previous modeling techniques improved by MCDM • Successful implementation: EBOLATOR • Multiple criteria influence diagram is an interesting modeling approach in MCDM
