*Intended learning outcomes: Present load profile calculation and problems associated with algorithms for load profile calculation. Explain methods of balancing capacity and load. Describe order-wise infinite loading.*

The primary objective of *infinite loading* is to achieve a high delivery reliability rate, i.e., to meet the due date for production or procurement orders. Secondary objectives are low levels of goods in stock and work in process and short lead times in the goods flow. High capacity utilization is less important. Indeed, there can be good strategic reasons for maintaining overcapacity (meeting due dates).[note 1402].

*Overview:* This section describes the generally applicable order-oriented method.[note 1403] Load profiles are calculated for all the orders together after scheduling, and each scheduled operation represents a load at the specified work center and in the time period containing its start date. The sum of all these loads is compared to the available capacity for each time period. This yields load profiles showing the overcapacity or undercapacity for each work center and time period. Subsequent planning then attempts to balance capacity against load.

This most commonly used *order-oriented-infinite-loading* technique is also called *capacity requirements planning (CRP)*.

*Planning strategy:* The objective is to manage fluctuating capacity requirements by having flexible capacity available. Both long-term and short-term actions are possible.
