Illustrative computer-executable methods, systems, and computer software program products compute assembly jack locations to align parts for assembly. Initial locations of at least one component to be moved and a desired final location for the at least one component to be moved are determined from initial position measurement data for the at least one component to be moved and the final location. Motion to align the at least one component to be moved with the final location is automatically determined. Optimal displacements of assembly jacks to produce the determined motion are automatically determined. After movement, location of the at least one moved part at a final assembled position is automatically determined. If applicable, data regarding additional assembly jack displacement can be inputted, the determined optimal location for the at least one part to be moved can be adjusted, and additional motion due to additional assembly jack displacement can be determined.
