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...

Hyper-heuristics: a survey of the state of the art
Hyper-heuristics comprise a set of approaches that are motivated (at least in part) by the goal of automating the design of heuristic methods to solve hard computational search problems. An underlying strategi...

Fuzzy mixture two warehouse inventory model involving fuzzy random variable lead time demand and fuzzy total demand
This paper considers a two-warehouse fuzzy-stochastic mixture inventory model involving variable lead time with backorders fully backlogged. The model is considered for two cases—without and with budget constr...

Why do managers avoid EPS dilution? Evidence from debt–equity choice
Survey evidence reveals that managers prefer to avoid dilution of earnings per share (EPS), though financial theory suggests it is irrelevant in firm valuation. We explore contracting and behavioral explanatio...

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...

A path-oriented encoding evolutionary algorithm for network coding resource minimization
Network coding is an emerging telecommunication technique, where any intermediate node is allowed to recombine incoming data if necessary. This technique helps to increase the throughput, however, very likely ...

Scheduling FMS problems with heuristic search function and transition-timed Petri nets
In flexible manufacturing system (FMS) scheduling problems, the production process and constraints can be modeled by Petri nets concisely. However, the search space for an optimal or suboptimal schedule will e...
