Integrating shelf life constraints in capacitated lot sizing and scheduling for perishable products (2018)
Presentation / Conference Contribution

In this study, we consider a multi-item capacitated lot sizing and scheduling problem for perishable food products, which have a fixed shelf life period due to depreciation issues, such as physical deterioration or perceived value loss. We incorporat... Read More about Integrating shelf life constraints in capacitated lot sizing and scheduling for perishable products.

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...

Production lot sizing and scheduling with non-triangular sequence-dependent setup times (2014)
Journal Article

This paper considers a production lot sizing and scheduling problem with sequence-dependent setup times that are not triangular. Consider, for example, a product that contaminates some other product unless either a decontamination occurs as part of a...

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...
