Risk limits, conflict, and equilibrium selection in games with multiple equilibria

Game theoretic analysis of two-period-dependent degraded multistate reliability systems
(Journal article; Peer reviewed, 2011)A system of two components is analyzed as a two-period game. After period 1 the system can be fully operational, in two states of intermediate degradation, or fail. Analogously to changing failure rates in dependent systems ... -
