An Algorithm for Minimizing the Range of Lateness on a Single Machine
This paper considers the problem of minimizing the range of lateness on a single machine. All the algorithms in the literature for solving this problem are based on the branch-and-bound approach, which has an ...

Value iteration and optimization of multiclass queueing networks
This paper considers in parallel the scheduling problem for multiclass queueing networks, and optimization of Markov decision processes. It is shown that the value iteration algorithm may perform poorly when t...

An effective heuristic algorithm to minimise stack shuffles in selecting steel slabs from the slab yard for heating and rolling
Steel production is a multi-stage process. A slab yard serves as a buffer between the continuous casting stage and the steel rolling stage. Steel slabs are stored in stacks in the yard. Shuffling is needed whe...

Multi-layered round robin routing for parallel servers
We study a system of several identical servers in parallel, where a routing decision must be made immediately on a job’s arrival. Jobs arrive according to a Poisson process, with their processing times followi...

Designing a secure e-tender submission protocol
This paper investigates the fundamental difference between a simple e-tender box and a traditional physical tender box, and highlights a series of security traps created by the functional differences. Based on...

A Pareto-based search methodology for multi-objective nurse scheduling
In this paper, we propose a search technique for nurse scheduling, which deals with it as a multi-objective problem. For each nurse, we first randomly generate a set of legal shift patterns which satisfy all s...

Network flow models for intraday personnel scheduling problems
Personnel scheduling problems can be decomposed into two stages. In the first stage for each employee the working days have to be fixed. In the second stage for each day of the planning period an intraday sche...
