An effective two-stage stochastic multi-trip location-transportation model with social concerns in relief supply chains (2018)
Journal Article

© 2018 Elsevier B.V. The distribution of emergency aid from warehouses to relief centers to satisfy the needs of the victims in the aftermath of a disaster is a complex problem because it requires a rapid response to human suffering when resources ar...

Applications of lot sizing (2018)
Presentation / Conference Contribution

Lot-sizing lies traditionally in the manufacturing sector, but it is applicable not just to related areas such as process industries and supply chains, but also to innovative areas such as humanitarian logistics. We look at some of the applications t... Read More about Applications of lot sizing.

A novel flexible model for lot sizing and scheduling with non-triangular, period overlapping and carryover setups in different machine configurations (2017)
Journal Article

© 2017, Springer Science+Business Media New York. This paper develops and tests an efficient mixed integer programming model for capacitated lot sizing and scheduling with non-triangular and sequence-dependent setup times and costs incorporating all...

The challenge of rescheduling nursing staff: Informing the development of a mathematical model decision tool (2014)
Report

Executive Summary: This report presents the findings and recommendations from a preliminary investigation into how an NHS organisation manages sudden nursing staff shortfalls. Unexpected staff absences, which can occur on a daily basis, can impact on...

Rescheduling nursing shifts: Scoping the challenge and examining the potential of mathematical model based tools (2013)
Journal Article

© 2013 John Wiley & Sons Ltd. Aim: To review research in the literature on nursing shift scheduling/rescheduling, and to report key issues identified in a consultation exercise with managers in four English National Health Service trusts to inform...

A preprocessing optimization applied to the cell suppression problem in statistical disclosure control (2013)
Journal Article

As organizations start to publish the data that they collect, either internally or externally, in the form of statistical tables they need to consider the protection of the confidential information held in those tables. The algorithms used to protect... Read More about A preprocessing optimization applied to the cell suppression problem in statistical disclosure control.

A priori reformulations for joint rolling-horizon scheduling of materials processing and lot-sizing problem (2013)
Journal Article

In many production processes, a key material is prepared and then transformed into different final products. The lot sizing decisions concern not only the production of final products, but also that of material preparation in order to take account of... Read More about A priori reformulations for joint rolling-horizon scheduling of materials processing and lot-sizing problem.

Single-stage formulations for synchronised two-stage lot sizing and scheduling in soft drink production (2012)
Journal Article

This study deals with industrial processes that produce soft drink bottles in different flavours and sizes, carried out in two synchronised production stages: liquid preparation and bottling. Four single-stage formulations are proposed to solve the s... Read More about Single-stage formulations for synchronised two-stage lot sizing and scheduling in soft drink production.

Adherence therapy for medication non-compliant patients with hypertension: A randomised controlled trial (2012)
Journal Article

The objective of this study is to establish the efficacy of adherence therapy (AT) compared with treatment as usual (TAU) in reducing blood pressure (BP) in non-compliant hypertensive patients. This study was designed as a parallel-group single-blind... Read More about Adherence therapy for medication non-compliant patients with hypertension: A randomised controlled trial.

Capacitated lot-sizing and scheduling with sequence-dependent, period-overlapping and non-triangular setups (2011)
Journal Article

In production planning, sequence dependent setup times and costs are often incurred for switchovers from one product to another. When setup times and costs do not respect the triangular inequality, a situation may occur where the optimal solution inc...
