A framework of irregularity enlightenment for data pre-processing in data mining
Irregularities are widespread in large databases and often lead to erroneous conclusions with respect to data mining and statistical analysis. For example, considerable bias is often resulted from many paramet...

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...

Adaptive selection of heuristics for improving exam timetables
This paper presents a hyper-heuristic approach which hybridises low-level heuristic moves to improve timetables. Exams which cause a soft-constraint violation in the timetable are ordered and rescheduled to pr...

Workforce scheduling and routing problems: literature survey and computational study
In the context of workforce scheduling, there are many scenarios in which personnel must carry out tasks at different locations hence requiring some form of transportation. Examples of these type of scenarios ...

Efficient extensions of the Myerson value based on endogenous claims from players
We achieve two efficient extensions of the Myerson value by introducing the Shapley value of the original game as endogenous claims of players. Capturing the feature of insufficiency in the surplus to be divid...
