Differential dynamic programing method is presented to determine the optimum shield system by minimizing a performance criterion, which is represented as a linear combination of three functions with respect to weight, cost, and thickness or dose, subject to certain constraints. A linear differential approximation is applied to the calculation of radiation attenuation, with 7 groups for both neutrons and gamma rays. The theoretical and experimental determination of the optimal configuration for a laminated iron-water shield are attempted. On propose, ici, la technique theorique d'optimisation pour rechercher le systeme optimise de la protection. C'est qu on rend au minimum le critere objectif sous la condition prealablement definie. Dans le procedure du calcul d'optimisation le calcul de decroissance de radiation est effectue par l'approximation du derivee primaire. On traite les problemes pour les geometries de plan, de sphere et de colonne par SOLA. Les experimentations se sont effetuees pour connaitre l'influence des arrangements differents sur l'effet de la protection.
