Usually, the framework is just a framework it does not need validation. For example refer to the paper:

  Dear Hamidreza Panjehfouladgaran, if expert opinion that you are using, it found in previous work and these are reliable sources, you only have to quote and reference these works.

  In particular, we are now working on inventories and need to affirm that have been studied from the point of view of risk aversion and for this we are simply quoting Chen et al., 2007 and making reference: Chen X., M. Sim, D. Simchi-Levi, P. Sun: Risk aversion in inventory management, Operations Research 55(2007)5, 828-842.

  I hope to have been useful somehow.

  Best regards,

Hi Hamidreza, Theoretically your framework is strong and somewhat valid as long as it based on 'Experts Opinions'. You achieved half of the way toward your goal 'Risk mgmt.' You need a number of case studies to validate the applicability of your work, this could be your next work or other researchers work whom build over your framework.

the following links may be reasonable references to your request 

 good luck
