5.1.7 How to realize the loading with a sequential order

When goods are mixed, sometimes it should be specified that which goods are loaded first and which goods are loaded later. For example, the goods need to be unloaded at different ports so that they need to be loaded sequentially. How to define relevant parameters in LoadMaster?

Let's use an example to explain.

Cargo data:

Name	quantity	length（cm）	width（cm）	height（cm）
A	220	55	36.0	36.0
B	393	48.0	36.0	36.0
C	222	52.0	42.0	36.0

Loading requirements:

1)The load orientations is only the height is vertical to the ground;

2)The loading sequence is C first, then A, and finally B.

3)Calculate how many containers will be used for this batch of goods, and what type of container is more suitable for loading.

According to the loading requirements, the task type [Loading Container/Multiple Cargo] should be selected and click to enter.

Enter the [Basic Information] interface. The items in this page is optional, and users can fill in the PO number, order number or destination information according to actual work requirements for later check. Next, start to designing the plan:

Step 1: Click [Cargo] on the left to enter the cargo interface. For there are lots of cargo types, you should add them in batches by [Add Cargo>Import From Excel]. Firstly, click [Add Cargo>Get Excel Template] to download the Excel template and save it to a certain location in your computer.

Secondly, fill in the template with the cargo information.

①Copy the name, quantity, length, width, height, and weight (gross weight of a single box) of the goods into the template, which are required items. Pay attention to the matching of the units. "Weight" refers to the gross weight of a single carton or box of goods. If the cargo is too light, the "Weight" can be ignored and not filled in, and the system will default to "1".

②Then define the load orientations of the goods. For it is required that cargoes can be placed as the height is vertical to the ground, that is only "stand" and "stand & rotate" are allowed, you should fill in "0" under the "allowed" Column of other orientations. "0" means not allowed such load orientation, leave it blank or "1" means allowed.

③For the cargoes have their own certain loading order, C first, then A, and finally B, it is necessary to set the "loading sequence" of the goods.

The loading sequence is a relative value. The larger the value, the earlier the goods are loaded. Therefore, the "loading sequence" of A, B, and C is set to "2", "1" and "3" respectively. In this way, LoadMaster will load the goods C first, and then cargo A, and finally cargo B when designing the loading plan.

For there are no other requirements, you do not need to set other parameters, leaving them as the default value. The specific details of each parameter can be found in this guidance documentation. Save and close the template when finishing.

Thirdly, return the [Cargo] page, click [Add Cargo>Import From Excel], choose the template in the dialog box, and open it. Then the cargo information will be imported to the task.

Step 2: Click [Container] on the left to enter the [Container] interface. For the user does not know the type and quantity of container that should be used, it is necessary to add all the commonly used container types so that the system can select the most appropriate container from such containers.

For the commonly used container information is already maintained in the database, click [Import from Database], check the 20GP, 40GP and 40HC in the pop-up box, and then click [Add]. Edit the corner castings size and reserved size of the container, the size of the corner castings is 10*10*10cm. Precautions for defining the reserved size, please refer to "How to simulate carton expansion and manual interval".

Step 3: Set the loading rules on the [Loading Rules] page. After setting the "loading sequence", you should pay attention to the setting of the [Cross depth]. Generally, the greater the cross depth value, the higher the loading rate.

So what is the cross depth? It will be more intuitive through the following example diagram.

The different colors in the picture represent different products. As you can see in the picture on the left, after installing a product, even if there is idle space above and on the right, the next product will not be loaded here. The reason is that the cross depth is set to "0", and the corresponding loading rate is 88%. In the picture on the right, there is a partial mix and match between the two adjacent products. The reason is that cross depth is set to 1 meter, and at this time the loading rate is increased to 92.46%. That is the importance of setting the crossing depth.

The default value of the cross depth in the system is 2 meters. In this case, you can first generate plan at the default value. Click [Optimize] above to get the loading plan. In the container list on the left, you can see that this batch of goods can be loaded by using one 40GP , and the loading rate of is 85.21%.

Through the 3D scheme diagram, it can be seen that the loading sequence is first cargo C, then cargo A, and finally cargo B, which meets the loading requirements.

If the crossover depth is set to 0, see what changes in the scheme.

Click [Optimize] to regenerate the plan. This batch of goods needs to be loaded with a 40HC. It can be seen from the 3D diagram that although the goods are loaded in the required order, there is an idle space at the junction of adjacent goods without mixing and matching. Therefore one 40GP can't be enough to install and a 40HC is needed. So when setting the "loading sequence" parameter, you must pay attention to the setting of the cross depth.

After the scheme audit is completed, you can use your mobile phone to guide the on-site loading and download the loading report to make the packing list and customs declaration. Details please refer to this guidance book.
