Scalarization functions for decision matrices

My thanks to the Ruddy Nice team for the opportunity to deliver this briefing remotely to the 2022 UK Defence Simulation Education & Training conference. In the briefing I show how the simplistic scoring mechanism commonly used by many civilian and military organizations in their decision matrices and more complex decision support tools simply does not make sense — being a linear scalarization function — and explain why that function must instead be concave up. Then, and only then, will your decision matrix satisfy the minimum reasonableness requirement.
