Oracle Transportation Management (OTM)Load Configuration 6.1

Sundar ArunapuramSr. Director, OTM Planning Development


Agenda

• Concepts – Container Optimization and Load Config

• Enhancements In 6.1– 3D Load Configuration– Compartment Logic– Container Optimization– ASK OTM, Diagnostics and Support

• Q & A


Concepts


Container Optimization and Load Configuration

• The objective of Container Optimization is to optimally pack a group of orders into available equipments of different sizes

• Container Optimization is invoked from several places within OTM such as bulk-plan, UI and agent actions that manipulate contents of equipment, and ASK OTM

• Load Configuration is a part of container optimization that uses equipment and product dimensions to compactly pack items into equipment.


3D Load Configuration


3D Load Config Features in 6.1

• Robust algorithm capable of producing better quality solutions than in earlier versions

• Takes into account the ERU limits and maximums while placing objects into container

• Works with multi-stop (P/D sequence handled correctly), and multiple compartments

• A new column generation based algorithm that is capable of optimizing multiple containers (like multi-container MIP) works with 3D engine

• Calculates loading length and provides the ability to rate by loading length


Turning on new 3D load Config - Planning Parameters

There is a new planning parameter that points to the logic config.You must also disengage the old planning parameters first.

These parameters are also used by the new logic config.


Turning on 3D load configContainer Opt Logic Configuration Parameter


Tuning Parameters – Container Optimization Logic Configuration


Logic Config Parameters

• LOAD PLACEMENT ITERATION CRITERIA – Specifies the emphasis for Spaces, Items and Rotations.

• The sort criteria of Items, Spaces and Rotations. – EMPTY SPACE SORT CRITERIA– ITEM SORT CRITERIA– ROTATION SORT CRITERIA

• EVALUATION DEPTH – how much control that the user would like to have versus having the algorithm optimize – possible values 0 to 3 (0 meaning full user control and 3 meaning full evaluation)

• PLACEMENT COMPARISON SCHEME – this is scheme used by the algorithm to compare between different placements – currently support only one scheme – Occupied Linear Length


LOAD PLACEMENT ITERATION CRITERIA

• Possible Values– Space, Item, Rotation– Item, Rotation, Space– Item, Space, Rotation– …

• In the Space, Item, Rotation scheme, the algorithm will first select the space (based on a sort criteria) and then attempt to place the items (again according to a specified sort criteria) in different orientations.

• In the Item, Rotation, Space scheme, the algorithm will first select an item and an orientations (according the sort criteria provided) and then determines the space that it can fit into.

ITEM AND ROTATION SORT CRITERIA

• Similar to Space, the ITEM SORT CRITERIA has several options forthe user

– 0: Largest Volume– 1: Largest Surface– 2: Largest Dimension– 3: Most Dense– 4: Stacking Index

• ROTATION SORT CRITERIA – works in conjunction with IS LENGTHWISE ORIENTATION FIRST

– 0: Upright, Onside, Prone– 1: Upright, Prone, Onside– 2: Onside, Upright, Prone– 3: Onside, Prone, Upright– 4: Prone, Upright, Onside– 5: Prone, Onside, Upright


Combined Order of Packing and Sort

Take the most dense first and use floor loading. Version 6.1 best solution

Take the greatest volume first and do nose loading. Version 6.0 best solution

Multi-stop Mixing Rule

• Planning Parameter – LOAD CONFIG MULTISTOP MIXING RULE controls how products going to various stops get mixed while loading

• Possible Values:– 0: No mixing allowed– 1: Widthwise mixing allowed– 2: Widthwise and stacking mixing allowed– 3: Widthwise and stacking mixing allowed for last row only

Load Config Considerations

• Load Config specific Constraints– Curved Roof (new in 6.1 for 3D load config)– Door Height– Stacking Height– Floor loading – can an item be loaded on the floor– Stacking Layer feasibility – whether can stack below or over other items– Overhang Constraint– Load bearing weight– Orientation feasibility individually as well as with respect to items

packed below– Stacking Index constraints

• In addition all of the general container optimization constraints are honored such as

– Weight, volume, ERU, temperature control, etc.

• The logic also calculates the axle weights at each axle and logs the information


Compartment Logic


Compartment Logic

• Prior to 6.1, users could define compartments, but there was practically no business logic for compartments

• Enhanced the container optimization logic to handle packing intocompartments and honor the compartment constraints

• Works with the new 3D load config engine as well as non-load config algorithms.

• Works with the new column generation based multi-container algorithm

• Honors weight, volume, temperature control, equipment to commodity compatibility and equipment, commodity to commodity compatibility and commodity mixing constraints

• Cortona Viewer can now display compartments

has been switched to the refrigerated compartment.

Container Optimization Enhancements


Container OptimizationEnhancements in 6.1

• Equipment Reference Units (ERUs)

• Multi-Container Optimization (Column Generation Based Algorithm)

• Change to container optimization pre-rating logic – It is still an approximation– However, it uses a more robust shipment rating rather than RIQ logic.

• Ability to specify a max length, width and height per ship unit on the equipment group.

• Repack Shipment action – ability to invoke container optimization / load configuration on an existing shipment


ERU Enhancements

• Ability to define multiple ERUs per ship unit spec (THU)

• Ability to define ERUs (multiple) directly on a ship unit – overrides the ones defined on the THU – you do not have a specify a THU in order to define ERU

• ERUs on Equipment Group is not changed

• Shipment view screen shows the ERU grid, with ERU and count.

• Can rate by ERU– Rate by number of ERUs arriving at a stop– Rate by ERU qualified by a specific ERU


Multiple ERU per THU


Case 1 - Multiple ERU per THU


Multiple ERU per Equipment

Propane Limits – Max is infinite. Used as a control.BBQ Limits – Is used to “consume space” for packing.


Results – Shipment Built

Column Generation – Multicontainer MIP Replacement

• Produced superior solution quality at the expense of runtime

• Is capable of handling all of the constraints and business logic such as

– Compartments– Multi-stop– ERUs– 3D Load config

• Uses other algorithms to produce solutions and finds the optimal combination of containers

failure.
