Abstract:
1. A computerized method for guiding personnel servicing selected locomotive equipment from a group of generally similar locomotive equipment, with said selected locomotive equipment being made up of a plurality of systems and subject to unique locomotive configurations and servicing requirements, said selected equipment requiring repair while at an equipment work site, with the personnel being guided through a plurality of tasks for evaluating the health of the equipment to identify the nature and extent of service needed, and determining at least one preferred work site location accesible through a railroad network for performing the services based on technical and business decision-making criteria, said method comprising: providing a database accessible from the equipment work site, the database comprising detailed data for health assessment and servicing of selected locomotive equipment, the database further comprising technical and business decision-making data regarding the service capabilities and availability, and costs of transportation to and servicing of equipment at available work sites for servicing the selected equipment; providing a respective locomotive equipment configuration identifier for uniquely identifying the selected locomotive equipment from among the group of generally similar equipment; configuring a servicing wizard for eliciting information regarding the identity and characteristics of the equipment to be repaired, providing instructions to the service personnel to determine the nature of the equipment fault and the servicing required for the equipment, and determining based on the technical and business decision-making criteria each preferred work site; providing a portable input/output device at each work site for communicating with the database from a location adjacent the selected eguipment to be serviced via a wireless communication connection; selecting the equipment to be serviced by communicating information indicative of the respective identifier for the selected equipment to the database through the portable input/output device; accessing the database to interface with the servicing wizard for the selected equipment; providing in response to a first set of prompts to the personnel from the servicing wizard at least one set of observations selected from the group comprising operational performance of the selected equipment and fault indications detected in the equipment, and further providing in response to a second set of prompts at least one set of technical and business decision-making criteria, including the cost and timeliness for performing services that may be required for the selected equipment and further providing a probabilistic estimation of whether a locomotive with the selected equipment can reach a respective work site before a road locomotive failure occurs as the locomotive travels on the railroad network; and processing said observation information, and said technical and business decision-making criteria relative to the servicing wizard to determine whether or not the selected equipment needs to be serviced, and if so the nature and extent of that service, said processing further determining a preferred work site from among the available work sites at which to perform the service in accordance with the technical and business decision-making criteria.
