A blood pump assembly includes a blood pump configured for implantation and a cable assembly for providing power and control signals to the blood pump. Load conditions are sensed by monitoring one or more signal characteristics that are affected by load conditions, such as voltage changes with respect to time. The system includes at least one production facility that includes a software code segment programmed to determine, in real-time, an incremental cost of a first resource based on a level of production of each respective facility. Methods for forming the apparatus are provided.
