Heuristic-Based Capacity Leveling:
Examples
This topic includes a few examples of heuristic-based capacity leveling. The following parameters have been chosen for the examples:
· Forward scheduling
· Resource capacity level: 100%
· Leveling method: Heuristic
· No consideration of priorities
Example 1: Leveling the Capacity of a Production Resource
Step 1
An order for 24 pieces of product PROD1 is loading resource RES1. The product is available on day 3. The production process model (PPM) activities are loading the resource on day 1, 2, and 3. The PPM has the following activities:
· Activity 1: Duration = 1 day, resource = RES1, variable bucket consumption = 1h
· Activity 2: Duration = 1 day, resource = RES1, variable bucket consumption = 2h
· Activity 3: Duration = 1 day, resource = RES1, variable bucket consumption = 2h, output product = PROD1, consumption = 1 PC
Step 2
Heuristic-based capacity leveling reduced the resource load on day 2 to 100% by reducing the quantity of the original order by 50% and creating a new order for the remaining 50% of the order quantity. Therefore, the system moved 50% of the original order into the future so its activities were outside of the period concerned (day 2).
Step 3
To level the resource load on day 3, the system moved the new order from day 5 to day 6.
Example 2: Leveling the Capacity of a Transportation Resource
Step 1
An order with a quantity of 30 pieces is to be transferred to a different location. The time of receipt at the destination location is day 3 at 12:00:00 h. The shipment duration is 24 h. Therefore, the activity loads the resource from day 2, 12:00:00 h until day 3, 12:00:00 h.
The following data was defined for the transportation lane:
· Resource: TRES1
· Shipment duration: 24 h
· Resource consumption 1 PC = 10 TO
Step 2
Heuristic-based capacity leveling leveled the resource load on day 2 by moving 10 pieces to day 4.
Step 3
To level the resource load on day 3, the system moved another 10 pieces to day 5.
