  This paper focuses on stochastic orders and its applications : policy limits
and deductibles. Further, many applications and some examples are given :
comparison of two families of copulas, individual and collective risk model,
reinsurance contracts and dependent portfolios increase risk. More precisely,
we propose a new model for insurance risks while we give some properties. To
this end, we obtain the ordering of the optimal allocation of policy limits and
deductibles for this model.
