Intended learning outcomes: Describe the bill of resources. Explain a way to establish a product load profile from a rough-cut process plan.
Continuation from previous subsection (1.2.5).
A bill of resources is a listing of the required key resources (components and capacities) needed to manufacture one unit of a selected product or product family.
A product load profile is a bill of resources where the resource requirements are defined by a lead-time offset.
In general, this is a matter of one-level rough-cut bills of material and/or routing sheets.
Example: Figure 1.2.5.2 shows two variants of a product load profile for the example in Figure 1.2.5.1. Notice the contraction to one structural level. To do this, lead-time offset must be calculated for each operation. The second variant additionally joins together all positions that load the same rough-cut resource within 10 units of time. This further reduces the complexity of the rough-cut business object.
Fig. 1.2.5.2 The product load profile: a one-level rough-cut bill of material and one-level rough-cut routing sheet.
In some cases, rough-cut business objects can be derived from detailed business objects in a direct fashion. Manual, synchronous modification of rough-cut and detailed business objects is difficult and expensive. Therefore, rough-cut business objects are often kept general enough that they will not be affected by changes in the detailed business object.
