Two-stage flexible supply contract with payback and information update
Cheaitou, Ali; Jemai, Zied; Dallery, Yves; Delft, … - In: European Journal of Industrial Engineering 4 (2010) 4, pp. 471-492
In this paper, we consider a two-stage supply contract model for advanced reservation of capacity, with payback option at the beginning of the selling season. Between the two decision stages, external information is collected that serves to update the demand forecast and permits to adjust the...

Solution of multidimensional knapsack problems via cooperation of dynamic programming and branch and bound
Boyer, Vincent; Baz, Didier El; Elkihel, Moussa - In: European Journal of Industrial Engineering 4 (2010) 4, pp. 434-449
This article presents an exact cooperative method for the solution of the multidimensional knapsack problem (MKP) which combines dynamic programming and branch and bound. Our method makes cooperate a dynamic programming heuristics based on surrogate relaxation and a branch and bound procedure....

Optimising the spatial pattern of landscape revegetation
Polyakov, Maksym; Pannell, David J.; Rowles, Alexei; … - Australian Agricultural and Resource Economics Society … - 2011
The spatial pattern of landscape reconstruction makes a substantial difference to environmental outcomes. We develop a spatially explicit bio-economic model that optimises the reconstruction of a heavily cleared landscape through revegetation. The model determines the spatial priorities for...
