14.4.2b Rough-Cut Infinite Loading — Example with two Rough-Cut Work Centers

Intended learning outcomes: Explain rough-cut capacity planning with two rough-cut work centers and the result after moving the completion date of one operation.

Continuation from previous subsection (14.4.2)

Figure shows the same resource profile, this time with two rough-cut work centers. The desired completion date causes an overload at rough-cut work center 2. In Figure, it has been brought into line by deferring the completion date by two periods.

Detailed planning may nevertheless still be needed if we use short-term rough-cut planning. The individual rough-cut operations for the order under consideration can then be shown separately. It is only by recording interdependencies between operations in the network plan that we are able to move the fifth operation forward from the period [19–20] (overload) to the period [18–19] (no overload), as shown in Figure To be able to work efficiently and interactively, it must be possible to view all the work centers at the same time. The entire resource profile for an order can then be moved at all the work centers simultaneously.

Course section 14.4: Subsections and their intended learning outcomes

  • 14.4.3 Rough-Cut Finite Loading

    Intended learning outcomes: Present the cumulative resource profile of an order as well as cumulative load and capacity before loading the order. Explain rough-cut planning of the cumulative load and capacity after loading the order.
