A model for an industrial process (elastomer vulcanization) is proposed and then the minimization problems and methods are pre- sented.

The effect of random perturbations on these methods is studied. Numerical results are given.

The interest of the coupling of stochastic and deterministic methods is shown. INTRODUCTION We are interested in a situation issued from thermal industry: the vul- canization.

Gamier [1] has shown that, while the curing of some elas- tomers, an exothermical reaction can occur and damage the material.

In order to avoid this destruction, a sharp control is essential and a fin...
