2. The problem

You are required to find the best pallet layout (case/pallet/truck) to enable transporting the maximum number of case per truck.

3. Solving with Stackbuilder

Launch StackBuilder

Use either desktop or menu shortcut clip_image008 to launch PLMPack StackBuilder.

clip_image010

Create a new project

 

Use either menu File>New or toolbar "New" clip_image012 to create a new project.

Once you have entered a project name and a description in the "Create new document..." form, the OK button should be enabled and you can click it.

clip_image014

 

The document explorer now shows your project.

clip_image016

 

 

Create a new case

 

Use either menu "Tools>New Case" or toolbar "New Case" clip_image018 button or right click the "Cases" branch in document explorer tree and select "Add new case" on context menu to create a new case.

Fill the "Create new case..." form with the correct name, description, dimensions and weight.

 

clip_image020

If you like, you can use the "Bitmap" button to paste one or several bitmaps on each side of the case.

Click OK to close the form and create the case.

You can check that the box "Match box" now appears under the Boxes branch in the document explorer tree.

 

Create a new pallet

 

Use either menu "Tools>New Pallet" or toolbar "New pallet" button clip_image022or right click the "Pallets" branch in document explorer tree and select "Add new pallet" on context menu to create a new pallet.

Fill the "Create new pallet" form with the correct name, description, dimensions and weight before clicking OK.

clip_image024

You can check that the pallet "EUR2" now appears under the Pallet branch in the document explorer tree.

clip_image026

Notice that the "Pallet analysis" tool is now enabled. This indicates that you could actually proceed with pallet analysis from now on. However, you need to define the interlayer first.

Create a new interlayer

Use either menu "Tools>New Interlayer" or toolbar "New interlayer" clip_image028 button or right click the "Interlayers" branch in document explorer tree and "Add new interlayer" on context menu to create a new interlayer.

Fill the "Create new interlayer" form with the correct name, description, dimensions and weight before clicking OK.

clip_image030

You can check that the interlayer now appears under the "Interlayers" branch in the document explorer tree.

clip_image032

Create a new truck

 

Use either menu "Tools>New Truck" or toolbar button "New truck" clip_image034 or right click the "Trucks" branch in document explorer tree and select "Add new truck" on context menu to create a new truck.

Fill the "Create new truck" form with the correct name, description, dimensions and weight before clicking OK.

clip_image036

 

You can check that the branch "Trucks" now host a "semi-trailer" truck.

clip_image038

Create a pallet analysis.

Use either menu "Tools>New Analysis" or toolbar button "Create new Analysis" clip_image040or right click the "Analyses" branch in document explorer tree and select "Add new analysis..." on context menu to create a new analysis.

clip_image042

Define a name and a description.

If you have defined several case or pallet, make sure the right one is selected in the corresponding combo box.

Check the interlayer check box and the interlayer period to 1.

Check both "Allow aligned layer" and "Allow alternate layer".

Check all layer patterns in the list of "Allowed layer patterns".

Click OK.

PLMPack StackBuilder then evaluates various solutions and displays an ordered array.

Solutions are ordered by decreasing efficiency.

You can navigate and visualize solutions by either using the mouse to select a row or moving the selection with arrow keys.

clip_image044

Select a solution among evaluated solutions

 

You can select a solution either by checking the check box at the right of the corresponding row or by clicking the "Select" button.

Once a solution is selected, a child tree node with a bulb light icon appears under the current analysis node.

clip_image046

 

Proceed with truck analysis

 

In the document explorer tree, right click the selected solution node and select "Add new truck analysis...".

clip_image048

Select a solution (one and only one) among the various truck solution.

If you attempt to select a second solution by clicking a check box despite an other row is already selected, this last row will be unselected.

 

clip_image050

 

Generate a report

 

In the document explorer tree, right click the solution element. In the context menu, select the "Generate report for ..." command with the MS Word icon clip_image051.

The software generates a Word ML report and launches MS Word. Let word convert this file from XML Document.

clip_image053

Report file: Case_44_28_29.doc

 

Save project

 

Either click the menu File>Save or the toolbar button "Save file".

A "Save as..." dialog appears and in which you can enter a file name such as "Case_44_28_29.stb".

 

4. Conclusion

 

With the defined case constraint, one can fit up to 1404 case by truck with a space efficiency of 55.71% .

Note: Results could be largely improved by increasing the maximum pallet height up to 2.6 m.
