Abstract: A computer-implemented system and method for determining optimal placement strategy for rental accommodations. The system is executed in a computer-implemented environment, and comprises a server and a visitor device in communication. The server is configured to receive a request data for placement strategy from the visitor and determine one or more placement strategies based on the request data. The request data includes check-in date, check-out date, location of interest and one or more amenities specified either as mandatory or as useful. A visitor assigns criterial monetary values for useful but not necessary amenities, for commute from the lodging unit to the location of interest, for moving from one to another lodging unit. The placement strategy includes information about moving from one premise to another within the same trip, the amount of the customer’s payment, and a criterial value that allows the visitor to choose the best value placement strategy.

Abstract: Disclosed is a system that prevalidates service orders placed by an interexchange carrier with a local exchange carrier for connection of the interexchange carrier with a business customer. An integrated prevalidation system and service order system is disclosed in which prevalidation requests are performed to ensure that a service order will be correct when submitted, thereby avoiding the necessity for expensive supplemental orders. The present invention further provides for generating accurate service orders based upon information separately maintained by the interexchange carrier regarding the local carrier's facilities and using prevalidation requests to reconcile the separately maintained information with the database of the local exchange carrier.
