Abstract: Methods and apparatus of modeling the costs associated with a system that includes a plurality of components are provided. In accordance with a preferred form of the present invention, a method includes using a first and a second node of a tree structure to represent a first and a second operation associated with the system. A branch of the tree structure is also used to represent a first dependency between the first operation and the second operation. A determination may then be made as to whether a third node, in addition to the first node, represents the first operation. In the alternative, a determination may be made as to whether a second branch branches from the first operation.

Abstract: A method and sampling system are provided for sampling and marketing fluid replacement services. Once an automobile arrives at the service facility, the automobile service technician quickly obtains fluid samples from the various systems of an automobile. While the consumer provides relevant information relating to the vehicle to a customer service technician, the automobile service technician places the fluid samples into receptacles allowing the consumer to visually inspect the condition of each fluid. The service technician then provides new fluids in proximity to the actual fluids of the engine to allow a side-by-side comparison of the visual condition of the fluids. The samples are then presented to the consumer while the consumer is in contact with the customer service technician to allow the consumer to make a determination as to whether the fluids must be replaced.
