Load-Oriented Order Release (Loor)
The first table in Figure 14.7.1.1 shows five orders with their sequence of operations. The data for each operation include the work center, the standard load (e.g., setup plus run time), and a blank column for entering the converted load.

The second table in Figure 14.7.1.1 shows parameters for load-oriented order release, as introduced in Section 14.1.2, as well as their values given for this exercise. The third table holds data for each work center, namely, the weekly capacity, the existing (pre-)load before loading the five orders, a blank column for entering the capacity upgraded by the loading percentage, and blank columns for the summarized load after releasing orders 1 to 5 (that is in the sequence given by the Loor algorithm).
a. Load the five orders according to the Loor algorithm.
b. What would have happened if for operation 3 of order 2 the standard load had been 200 units of time instead of 120 ?
c. Discuss whether in your solution the treatment of order 3 was efficient.
d. What would have happened if order 3 had been loaded before order 2 ?
