1. Software comprising processor-executable instructions stored in one or more tangible, non-transitory computer-readable media that when executed perform a method of providing a production metric about a physical production line comprising an arrangement of physical entities, said method comprising: (a) presenting one or more interactive entity configuration views on a display of a workstation; (b) receiving user inputs to said one or more interactive entity configuration views, said user inputs including entity data representing one of said physical entities; (c) generating an entity data model from said entity data; (d) repeating steps (a) through (c) to generate an entity data model for each of the physical entities in the physical production line; (e) presenting one or more interactive line configuration views on said display of the workstation, at least one of said one or more interactive line configuration views having a work area and a palette of entity configuration objects, at least a plurality of said entity configuration objects representing said entity data models generated in steps (c) and (d); (f) receiving user inputs selecting said plurality of said entity configuration objects and placing them on the work area to create a graphical object model representing the physical production line, said graphical object model comprising an arrangement of entity objects representing said arrangement of physical entities; (g) generating a line data model based on said user inputs; (h) receiving production data about the physical entities; (i) determining a production metric of the physical production line using the production data and the line data model; and (j) displaying the production metric on said display.
