New variants of variable neighbourhood search for 0-1 mixed integer programming and clustering [PDF]
, 2010 This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Many real-world optimisation problems are discrete in nature.

Simple Integer Recourse Models:Convexity and Convex Approximations [PDF]
, 2004 We consider the objective function of a simple recourse problem with fixed technology matrix and integer second-stage variables. Separability due to the simple recourse structure allows to study a one-dimensional version instead.

Convex approximations for complete integer recourse models [PDF]
, 2002 We consider convex approximations of the expected value function of a two-stage integer recourse problem. The convex approximations are obtained by perturbing the distribution of the random right-hand side vector.

On multiple simple recourse models [PDF]
, 2002 We consider multiple simple recourse (MSR) models, both continuous and integer versions, which generalize the corresponding simple recourse (SR) models by allowing for a refined penalty cost structure for individual shortages and surpluses.

Modelling and solution methods for stochastic optimisation [PDF]
, 2011 This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.In this thesis we consider two research problems, namely, (i) language constructs for modelling stochastic programming (SP) problems and (ii) solution ...

Convex approximations for a class of mixed-integer recourse models [PDF]
, 2004 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.

Evaluation of factors affecting greater prairie‐chicken nest and brood survival
Wildlife Biology, EarlyView.Greater prairie‐chickens Tympanuchus cupido pinnatus in the Flint Hills ecoregion select recently burned grasslands for brooding and nest in areas that have been unburned for 1–3 years, suggesting the need for a mosaic of burn patches. However, it is unknown how patch area, configuration, and proximity to edges within such mosaics affect reproductive ...

Nocturnal Behavior of Wintering Common Cranes (Grus grus) Under Varying Environmental Conditions
Integrative Zoology, EarlyView.For diurnal species, nighttime represents a critical ecological boundary. Understanding the ecological determinants of nocturnal activity in taxa traditionally regarded as inactive after dusk is essential for elucidating the adaptive significance of nighttime behavior. We examined how night phase, nocturnal brightness (moon illumination and cloud cover)

Collusion through debt and managers
Canadian Journal of Economics/Revue canadienne d'économique, EarlyView.Abstract We investigate the anticompetitive effects of debt financing and managerial incentives in the presence of managers incurring personal bankruptcy costs. We characterize the strategic value for firms' shareholders of resorting to debt and managerial incentives as complementary devices to sustain collusion among firms, when managerial bankruptcy ...

Integrated location–inventory planning for slow‐moving demands with waiting time limitations
International Transactions in Operational Research, EarlyView.Abstract This paper studies a stochastic facility location problem integrated with inventory and transportation decisions (SFLPIT) for supply chains with slow‐moving stock‐keeping units (SKUs). Local stores often avoid maintaining such SKUs, resulting in customer demand being fulfilled directly by a central distribution center (DC), where the ...
