Defining Pull Sequences
SOURCE TAB
For every kanban planned item, you must define a pull sequence, which is a series of kanban locations that model the replenishment network on the shop floor. A kanban location can be a subinventory or an inventory locator. The replenishment source for a kanban location can be another kanban location, a production line, or an external source. You can use locators even if locator control is turned off at the organization, subinventory, and item levels.
Kanbans can be sourced from an external supplier or an internal organization. A Supplier Source Type kanban triggers a purchase request to the supplier, while an inter-org. Source Type kanban results in an interorganization transfer.
Choose Planning Only if you want the program to perform the kanban calculations for you, but you will use a manual system to execute the kanbans. You will be able to calculate kanban sizes but will not be able to generate and print kanban cards or execute the replenishment cycle.
Auto Request
Select the Auto–Request check box enable auto requests for the pull sequence. This calls the Auto Replenishment for manufacturing concurrent request, which picks up the pull sequences and generates non–replenishable kanban cards for the pull sequences
Caluclate
Specify what you want the kanban system to calculate, it can either be Number of cards, Kanban size and do not calculate.
See next chapter for details
You will choose what you want the program to calculate: kanban size or kanban cards. The product of kanban size and number of kanban cards (or containers) will satisfy the demand at capacity for the planning horizon. Kanban size refers to the number of items in each kanban container. Each kanban container has one kanban card, so the number of kanban cards is the same as the number of kanbans for each item.
Enter Minimum Order Quantity (Optional)
Minimum Order Quantity represents the minimum number of units per kanban container. It is used when calculating kanban size or during the kanban execution process to aggregate kanbans smaller than the minimum order quantity. This field defaults from the Item Master window but can also be overridden.
Replenishment Lead Time
The Replenishment Lead Time must be expressed in days. This is how long it will take to physically replenish the kanban. For example, if you enter two days, the Kanban Planner will size the kanban to two times the average daily demand. If you leave the field blank, the program will assume replenishment is one day when calculating kanban sizes.
Additional Information: Production kanbans use the replenishment lead time to calculate the size of the kanban but use the Lead Times on the Item Master window to determine when to schedule jobs created by replenishing the production kanban. This allows you to add lead time on the pull sequence of the production item for transportation, or desired ”queue
time.”
Supplier and inter–org kanbans use the replenishment lead time to calculate the size of the kanban and to schedule the ”need date” for the purchase requisition. However, if you leave this field blank, the program will use one day to size the kanban and will use the lead time defined in the Item Master window for the ”need date” on the requisition. (Need date = sysdate + pre–processing + processing + post processing time if the replenishment lead time on the pull sequence is left blank.)
Allocation Percent (Optional)
The allocation percent represents the percent of independent demand for the kanban item that is to be supplied from this pull sequence.
Lot Multiplier (Optional)
When kanban planning sizes the containers at the location, it will size in multiples of this quantity. For example, if the supplier sells wire in a roll of 500 feet, then a multiplier of 500 would result in bin sizes of multiples of 500 feet. If demand called for 510 feet, the kanban planner would size the kanban for 1000 feet (500 + 500).
Safety Stock Days (Optional)
Safety Stock Days is the number of days demand that will be added to the kanban for safety stock. Kanban planning sizes kanbans to the average daily demand of the forecasted period.
