Accelerating convergence in the Fermat-Weber location problem
This paper presents a simple procedure for accelerating convergence in a generalized Fermat–Weber problem with lp distances. The main idea is to multiply the predetermined step ...

On-line scheduling of unit time jobs with rejection: minimizing the total completion time
We consider on-line scheduling of unit time jobs on a single machine with job-dependent penalties. The jobs arrive on-line (one by one) and can be either accepted and scheduled, o...

A push-pull queueing system
We consider a two node multiclass queueing network given by two machines each with two classes. There are two streams of jobs: One stream originates in machine 1, which feeds it f...

Linear dependence of stationary distributions in ergodic Markov decision processes
In ergodic MDPs we consider stationary distributions of policies that coincide in all but n states, in which one of two possible actions is chosen. We give conditions and formulas...

Complexity of two dual criteria scheduling problems
In this article we answer the complexity question of two dual criteria scheduling problems which had been open for a long time. Both problems are single machine scheduling problem...
