Convex approximations for a class of mixed-integer recourse models
We consider mixed-integer recourse (MIR) models with a single recourse constraint.We relate the secondstage value function of such problems to the expected simple integer recourse (SIR) shortage function.

An Extended Formulation With Valid Inequalities for the Capacitated Steiner Arborescence Problem
Networks, EarlyView.ABSTRACT Given a directed graph, the Capacitated Steiner Arborescence Problem (CSAP) aims to determine the least‐cost connection from the root node to terminal nodes requiring a demand through Steiner nodes coming with a capacity, such that there is a unique path from the root to each terminal. This paper presents a new extended formulation of the CSAP,

Mixing sets linked by bidirected paths [PDF]
Recently there has been considerable research on simple mixed-integer sets, called mixing sets, and closely related sets arising in uncapacitated and constant capacity lot- sizing.

A Chance‐Constrained Model for a Production Routing Problem With Uncertain Availability of Vehicles
Networks, EarlyView.ABSTRACT The Production Routing Problem (PRP) is a complex integrated problem that allows for the achievement of competitive advantages, such as better management of inventory, reduction in operational costs and lead times, improvement in efficiency and customer service, and better response to market changes.

Asset liability management modeling using multi-stage mixed-integer stochastic programming
A pension fund has to match the portfolio of long-term liabilities with the portfolio of assets. Key instruments in strategic Asset Liability Management (ALM) are the adjustments of the contribution rate of the sponsor and the reallocation of the ...

Optimizing Household Waste Recycling Centre Network Reorganization in Hampshire
Networks, EarlyView.ABSTRACT Local councils across the UK are facing sustained financial pressures, and Household Waste Recycling Centres (HWRCs) are being increasingly considered for closure to reduce expenditure. In 2024, Hampshire County Council, which operates the largest HWRC network in the UK, proposed closing either five or twelve existing sites.

Mixed integer programming models for fire fighting
In this paper, a set of mixed integer programming (MIP) models to optimize the location of a set of resources when fighting fire is proposed. The MIP model integrates fire spread and the decisions relative to the resources location.Four problems are ...

Oikos, EarlyView.Forest restoration success depends crucially on the reinitiation of ecological processes such as seed arrival that drive natural regeneration. We know little about whether, by increasing and diversifying local seed sources to alleviate seed limitation, and attracting animal frugivores to alleviate dispersal limitation, restoration could shift seed ...
