Lead Time Management at Littlefield Labs
Littlefield Laboratories has opened a new blood testing lab. This laboratory uses the same process as the lab encountered in your prior assignment, Capacity Management at Littlefield Labs—neither the process sequence nor the process time distributions have changed. The lab began operations with a raw materials inventory of 160 kits and $1,000,000 cash. Customer demand continues to be random, but the expected daily demand will not change during the lab’s life span. Expert advisors know that demand will end abruptly on Day 268 and the lab will no longer be necessary. Any remaining machinery or inventory will be useless after Day 268, and thus have no residual value.

A contract may be assigned to future orders by clicking the Edit Data button on the Customer Order pop-up window and selecting from the resulting menu.
Littlefield’s laboratory simulation will run at the rate of 4032 simulated days per real day for one real hour. On simulated Day 218, you will relinquish control of Littlefield’s lab and the simulator will run its final 50 simulated days at an accelerated rate. Management expects that you will leave all laboratory parameters set to values that maximize their
