Breakdowns of Modernization

Breakdowns ∗ Godfrey Keller

We study a continuous-time game of strategic experimentation in which the players try to assess the failure rate of some new equipment or technology. Breakdowns occur at the jump times of a Poisson process whose unknown intensity is either high or low. In marked contrast to existing models, we find that the cooperative value function does not exhibit smooth pasting at the efficient cut-off beli...

Constitutions and Democratic Breakdowns

Scheduling with Unexpected Machine Breakdowns

We investigate an online version of a basic scheduling problem where a set of jobs has to be scheduled on a number of identical machines so as to minimize the makespan. The job processing times are known in advance and preemption of jobs is allowed. Machines are non-continuously available, i.e., they can break down and recover at arbitrary time instances not known in advance. New machines may b...

Medicare, Modernization and FEHBP

Most capitated programs have not generated innovative ways to organize care, but have instead concentrated on enrolling healthy beneficiaries and using crude controls on service use. Competition can lead to a number of problems for beneficiaries, including instability in the care they receive. Choice of plans will not offer many advantages for beneficiaries, particularly since it is important t...

Model-Driven Software Modernization

This thesis elaborates the Model-Driven Software Modernization (MDSM), that has been identified by us, and is defined as a group of approaches toward modernization of legacy code. MDSM approaches are based on models, tools and processes known from the Model-Driven Engineering (MDE) that aims in automation of modernization process. This thesis describes identified MDSM approaches and related sta...
