  1. Rating, Ranking, Voting EST581 Decision Making

  2. We have already discussed rating • Including “SMART” rating systems • So we won’t look at that any more.

  3. Ranking • In consensus ranking, each participant ranks the alternatives 1, 2, …, n • With 1 being the most desirable • The decision is made based on averaging the rankings. • Note that ties are possible.

  4. Voting: Systems allowing one vote per participant • Majority voting • Winner must get majority of votes cast. • Run-offs may be necessary. • Plurality voting • Alternative getting most votes wins. • No run-off except in case of tie.

  5. Voting: Systems allowing a participant to cast multiple votes • Approval voting • Vote for as many candidates/alternatives as you approve of. • Maximum of one vote per person per alternative • Allocation voting • You are given (say) ten votes to allocate across candidates. • You may give a candidate more than one vote.

  6. Let’s do an experiment: Pick an artist to perform at your graduation. • The Beatles • Lady Gaga • Lead Zeppelin • Justin Bieber • KISS • Diana Ross • Rihanna • Taylor Swift • Elton John • Judy Garland • Martha Vaughn • Theloneus Monk • ABBA • Maria Callas • Cliff Richard • Janet Jackson • Luciano Pavarotti • Madonna

  7. We’ll use all 6 methods, separately. • Rating: 1 (best) to 10 (worst) • Ranking: 1 (best) to 10 (worst) • Majority voting • Plurality voting • Approval voting • Allocation voting (10 votes/person) • 6 tally-masters will be appointed to count votes.
