Abstract: A risk relationship resource model data store contains electronic records for risk relationship resource models. Each electronic record includes an electronic record identifier, model version identifier, period definition, and layer information. A computer server retrieves, from the data store, information about a risk relationship resource model including the model version identifier, period definition, and layer information. The computer server may then receive, from a remote user device, an adjustment to the risk relationship resource model and execute the model, including an experience rating process and an exposure rating process, to generate a prospective resource amount (based in part on the period definition and the layer information). Information about the adjusted risk relationship resource model, including an updated model version identifier, may then be stored into the data store.
