SSAS includes a tool called the Deployment Wizard which will do exactly what you need.  The Deployment Wizard uses the artifacts created by your SSAS project and can perform the deployment and/or generate an XMLA script that can be used to perform the deployment at a later time.  XMLA stands for XML for Analysis Services and it is the native protocol used by SSAS.  All commands sent to SSAS are in the XMLA format.  An XMLA script is an XML file.  The ability to generate the XMLA script allows the developer to provide the IT team what they need to perform the deployment.  In this tip we will review the BIDS artifacts, walk through the Deployment Wizard to create the XMLA script, then show the options to execute the script.
