Process Capacity: Capacity of the bottleneck. Demand: rate units are requested from a process. Flow Rate: R = Minimum of (Demand, Process capacity) Utilization = Flow Rate/ Capacity Implied Utilization = Demand / Capacity units those produce to Time produced units of Number Capacity Demand constrained = Demand is less than process capacity. Supply constrained= Process capacity is less than demand.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
