Transportation Planning Theories & Concepts

Transportation Planning (Overview) Objective of Transportation planning: To group delivery into shipment in order to minimize: 1) the number of shipments, and 2) the length of the shipments. Transportation planning: Carried out after delivery note is created in the sales (fulfillment) process. Is executed either automatically several times per day to deliver in batches, or manually by the transportation planner.

Level of Detail and Time Horizon of TP/VS and Deployment in APO Modules (review)

Overview Master Data and Application in TP/VS (review)

Transportation Planning Overview  Inputs to transportation planning:  due date of customers’ orders,  customers’ calendar of loading and unloading,  capacity restriction of vehicles,  vehicle availability, and  incompatibility (e.g. of the goods and locations).  TP/VS offers an optimization tool for transportation planning.  The transportation planning creates “shipments” in APO.

Transportation Planning Overview  After creation of a shipment, the subsequent steps are  To select a carrier, and  To release the shipment.  The shipment is transferred to ERP after it is released in APO.

Transportation Planning Process in APO 1.Create shipments in TP/VS 2.Assign transportation resource to each shipment 3.Assign carrier(s) to each shipment 4.Release shipments

Order Life Cycle for Transportation Planning

Transportation Planning Overview  TP/VS plans for orders which contain a start location (LOCFROM) and a destination location (LOCTO).  Inbound documents:  purchase orders  Outbound documents:  delivery notes, sales orders, stock transfer orders, and return orders.  ERP and APO don’t combine inbound and outbound orders in one shipment.

Master Data for TP/VS  The main master data for TP/VS are:  locations  manufacturing plant,  distribution centers,  customers,  transportation zone,  transport service provider.  transportation lanes,  means of transport, and  vehicle resources.

Master Data for TP/VS Means: speed, shifts Mode: by sea, land, air

Master Data for TP/VS  Transportation Zone and Transport Service Providers:  Transportation zones and transport service providers (carriers) are location types 1005 and 1020, respectively.  Transportation zone data are stored in Customer Master data in ERP and are transferred to APO.

Master Data for TP/VS  Transportation Lanes (routes):  Transportation lanes are defined from plants and DCs to (customer’s) transportation zone, and are created manually in APO except for lanes from vendor to manufacturing plant after the purchasing info records transferred from ERP to APO.  The allowed carriers are assigned per transportation lane (route) and transportation means.

Vehicle Modelling  Three entities for vehicle modelling are:  Mode (by sea, truck, rail, or air)  Means of transport (speed such as normal or express), and  Vehicle resources  Mode is maintained with the customising path and is used only for grouping purpose, such as by sea, by air, by truck.  Means of transport corresponds to speed (normal vs. express), or shift.  Vehicle resources: vehicle type, category, and capacity (tonnage T) (e.g. a resource with the capacity of 20 T is not allowed to load 22 T products.

Entities for Vehicle Modelling Wiggle factor: change range

Carrier Selection  Criteria for selecting carriers:  service-quality-based priority, and  cost.  Carrier selection is performed after the planning for shipments is done, and before the shipments are transferred to SAP ERP.  If one stage of transport is already assigned to a carrier which has the flag for continuous move, the same carrier is selected for succeeding stage.

Keep the same carrier for continuous move Carrier Selection principle

Deployment Overview  Scope of Deployment  To handle the deviation between demand and supply happens.  Basic idea of deployment is to convert planned stock transfers into confirmed stock transfers according to the available supplies, the demand, the deployment strategy, and the fair share rule.  If the demand exceeds the supply, it has to be decided which demand at which location will be covered and to what extent.

Deployment Overview  Available-to-deploy (ATD)-receipt and ATD-issues are category groups which are assigned to the location and location product master.  ATD-receipt:  Stock  Production order for finished goods  Purchase order for raw/trading materials.  ATD-issues:  Deliveries  Confirmed distribution requirements  Safety stock is ignored by deployment. Safety stock is modelled as a demand in SAP APO, not a supply element.

Deployment Heuristic  Deployment heuristic is a source-location-by-source-location approach to distribute the ATD quantities.  Deployment is based on short term data and is a step towards execution.  Deployment horizon defines the maximum horizon for which orders are ready.  Deployment pull horizon defines the horizon for the relevant requirement (ATD-issues).  Deployment push horizon defines the horizon for relevant ATD- receipt, e.g. production order (see Figure 12.2).

Deployment Horizons

Deployment Strategy for Heuristic SNP only uses push rules to calculate deployment if the ATD quantity covers the demand. The following rules are available:  Pull deployment:  Deployment fulfills all of the demand within the pull deployment horizon. Products are distributed according to the due date specified at the demand locations. The system does not distribute any supply to the demand source in advance of the demand date.  Pull/Push deployment:  The system immediately distributes all supply to the demand locations (ignoring the demand dates specified at the demand locations) to fulfill all demands within the pull deployment horizon.  Push by demand:  System immediately distributes the entire supply for the entire planning horizon to the demand locations to fulfill all demands. The pull deployment horizon is ignored.

Example of Deployment Strategy The following example illustrates the three push rules: Pull distribution, pull/push distribution, and push distribution by demands.

Example of Deployment Strategy The following example illustrates the three push rules: Pull distribution, pull/push distribution, and push distribution by demands.

Fair Share If demand exceeds supply, the system can use fair share rules to calculate deployment using the available-to-deploy (ATD) quantity. Various methods use fair share rules to assign a limited amount of available product to sources of demand. The following rules are available  Rule A: Percentage distribution by demand  Rule B: Same absolute quantity of shortage for target locations  Rule C: Percentage division by quote arrangement of source location  Rule D: Division by priority of target locations.

Fair Share Rules A and B

Transport Load Builder (TLB)  Transport load builder is a planning tool for execution to combine confirmed distribution orders to form truckloads or other transport units according to the capacity restrictions.  The use of TLB is an optional step in distribution and replenishment planning.  TLB planning follows the deployment run and uses confirmed distribution orders as input.

Transport Load Builder (TLB)  TLB procedure is to load all selected deployment orders according to the restrictions in TLB-profile  Two loading approaches (shown in Figure 12.14)  Straight loading  The orders are stored according to the loading group.  Load balancing  Distribute the products to be loaded evenly onto different truck loads

Straight Loading vs Load Balancing

Capacity Restrictions for TLB  Relevant capacity restriction in the TLB profile includes the following constraints:  Maximum volume,  Maximum weight, and  Maximum number of pallets.  A lower limit exists as well to inhibit uneconomical transport orders.
