Evaluating Price Stabilization Schemes with Mathematical Programming

American Journal of Agricultural Economics, 1981
Price stabilization schemes for risky agricultural markets continue to attract interest. Applied welfare economics has offered some insights into who gains from stabilization (Turnovsky). Economic models, such as stochastic simulation and dynamic programming, have been used to evaluate the costs of alternative stock sizes and storage rules (Reutlinger:

A Lagrange Scheme for a Mathematical Model of Powder Compression

SIAM Journal on Scientific Computing, 2001
A mathematical model to simulate the compression of pharmaceutical powder under fixed deformation is proposed. This model is an hydrodynamic one, completed with the description of the porosity in the medium. This study leads to the elaboration of a general monodimensional model, made of three nonlinear partial derivative equations and a state law for ...

On general decomposition schemes in mathematical programming

1985
A general decomposition technique in ordered structures is described which can be applied to algebraic mathematical programs and which reduces to Benders’ and Dantzig-Wolfe decomposition in the classical linear case. This approach enables applying decomposition to problems involving bottleneck, multi criteria and fuzzy functions with real or integer ...
