Determine optimal k using Silhouette index

Hi community, 

can someone help me with regard to the question how the k-values of k-Means Clustering approach can be evaluated by using Silhouette index within RapidMiner?

Are there other alternatives to effectively evaluate the k-value beside the x-Means operator in RapidMiner? What would you recommend? 

Thank you in advance! 

Best regards!
