Davis, Paul K.: Uncertainty Sensitivity Planning; in: Johnson, Stuart; Libicki, Martin; Treverton, Gregory F. (Eds.): New Challenges – New Tools for Defense Decision Making, 2003, pp. 131-155; ISBN 0-8330-3289-5.

Who is better than planning for very complex environments than the military?  On projects we set-up war rooms, we draw mind maps which look like tactical attack plans, and sometimes we use a very militaristic language.  So what’s more obvious than a short Internet search on planning and military.

Davis describes a new planning method – Uncertainty Sensitivity Planning.  Traditional planning characterises a no surprises future environment – much like the planning we usually do.  The next step is to identify shocks and branches.  Thus creating four different strategies

  1. Core Strategy = Develop a strategy for no-surprises future
  2. Contingent Sub-Strategies = Develop contingent sub-strategies for all branches of the project
  3. Hedge Strategy = Develop capabilities to help with shocks
  4. Environmental Shaping Strategy = Develop strategy to improve odds of desirable futures

Uncertainty Sensitivity Planning combines capabilities based planning with environmental shaping strategy and actions. 
Capabilities based planning plans along modular capabilities, i.e., building blocks which are usable in many different ways.  On top of that an assembly capability to combine the building blocks needs to be planned for.   The goal of planning is to create flexibility, adaptiveness, and robustness – it is not optimisation.  Thus multiple measurements of effectiveness exist. 
During planning there needs to be an explicit role for judgements and qualitative assessments.  Economics of choice are explicitly accounted for. 
Lastly, planning requirements are reflected in high-level choices, which are based on capability based analysis.

Application of Multicriteria Decision Analysis in Environmental Decision Making (Kiker et al., 2005)

Kiker, Gregory A.; Bridges, Todd S.; Varghese, Arun; Seager, Thomas P.; Linkov, Igor: Application of Multicriteria Decision Analysis in Environmental Decision Making; in: Integrated Environmental Assessment and Management, Vol. 1 (2005), No. 2, pp. 95-108.

Kiker et al. review Multi-Criteria Decision-Making (MCDA).  The authors define MCDA as decisions, typically group decisions, with multiple criteria with different monetary and non-monetary values.  The MCDA process follows two steps – (1) construct a decision-matrix, (2) synthesis by ranking alternative by different means.

What are solutions/methods to apply MCDA in practice?

  • MAUT & MAVT
    multi-attribute utility theory & multi-attribute value theory
    = each score is given a utility, then utilities are weighted and summed up to choose an alternative
  • AHP
    analytical hierarchy process
    = pairwise comparison of all criteria to determine their importance
  • Outranking
    = pairwise comparison of all scenarios
  • Fuzzy
  • Mental Modelling
  • Linear Programming
