Approximation Algorithms for Scheduling Multiple Feasible Interval Jobs
Abstract— Time-critical jobs in many real-time applications have multiple feasible intervals. Such a job is constrained to execute from start to completion in one of its feasible...

Scheduling Jobs with Multiple Feasible Intervals
This paper addresses the problem of scheduling real-time jobs that have multiple feasible intervals. The problem is NP-hard. We present an optimal branch-and-bound algorithm. When...

Minimizing Busy Time in Multiple Machine Real-time Scheduling
We consider the following fundamental scheduling problem. The input consists of n jobs to be scheduled on a set of machines of bounded capacities. Each job is associated with a re...
