Create or Import provision requirements

For a transport and resource calculations ipolog needs information about the production to be planned.

This is based on the staging requests. These include the number of parts required per concrete product for a given point in time.

In the submodule Production Data, you import the staging requests from ipolog 4 Workspace and create dummy requests based on the logistics quantity structure.

Create material staging requests from the logistics quantity structure:

To create staging requests in the software, it is necessary that a logistics quantity structure has already been imported into ipolog 4 Material Flow.

In order to exclude a possible error potential, it is also recommended that a layout already exists in the software.

The production data in ipolog are distinguished as "Base product" and "Detailed calculation".

Base Product

in the Base product area, provisioning requests can be created or imported from ipolog 4Workspace.

If the supply requirements are to be generated directly in the software on the basis of the LMG, click on the button "Generate provision requirements from the logistics quantity structure".
For the calculation of the provision requirements for the base product the columns assembly rate [%] and parts per product of the lqf file are in use. 

In the dialog that opens, the product name, the start and enf of the production and the shift plan must be defined. The user can then define either the number of products per day or the cycle time. The other value is automatically calculated by the software. Provision requirements can be generated over a period of up to 30 days.

Confirmation is done via the button "Create PR".

The provision requests are then created on the basis of the logistics quantity structure in the table on the right-hand side of the screen.

The calculation of the provisioning requirements can be found here.

Importing Deployment Requests from ipolog 4 Workspace

To import provisioning requests into the software, first open the Production Data submodule in the project configuration.

Then click on the button "Import provisioning requests from jsn file" (see screenshot).

A window then opens for the user through which the exported deployment requests can be imported from ipolog 4 Workspace.

With Release 2019-06, you must select the shift plan to be used in production after importing the provisioning requirements.
For existing projects, the shift schedule must be defined in the production data. Only then are the transports in these projects calculated.

To the left of the table view, the calculated output and the cycle time stored in the provision requests are displayed for the user. Information on the start of production or the import can also be obtained here.
The output displayed when importing provisioning requirements is output based on the number of products defined in the imported production program of ipolog 4 Workspace.
The cycle time displayed by ipolog 4 Material Flow also corresponds to the specification stored in ipolog 4 Workspace as the cycle time when the provision requests were exported.

After the import, the user can also use the Log button to find out whether there are any discrepancies between the materials in the logistics quantity structure or the layout and the supply requirements.

After the import into the software, the import file must be saved using the save button in the software.

You can read about the export of provisioning requests from ipolog 4 Workspace here. 

Detailed calculation

In the detailed calculation it is possible to define an output for more than one product (=product mix). In this case ipolog calculates the production data based on the concrete assembly rates and parts per product defined for each log ID in the logistic quantity structure. The assembly rates and parts per product must be defined in the user-defined columns. For the assembly rates and parts per product, the following must be added in the custom columns:

• custom assembly rate product name
• custom parts per product name

For example, this may look like the following:

For the detailed calculation only columns that fit the scheme above are in use. The columns parts per product and assembly rate [%] from lqf are only used for the base calculation and not for the detailed calculation. 

In the first part the production start day and production end day can be defined (1). In the second part, the product groups can be defined by adding the products to the product groups. Each product can only be assigned to one product group. The individual products are listed on the left side (2). These can be assigned to a group on the right side (2). The blue highlighted group is active and can be changed by a click with the left mouse button. To add a product to a group, the respective product can also be added to the active product group (3) on the left side (2) by clicking on the left mouse button. The products will then be listed under "products".

In the product group itself, a shift schedule can also be selected for each group.

The group cycle time [sec] results from the added products and the respective number of products/day (4) calculated on the production period. The products are distributed evenly over the production period.

Another group can be added via the "+" or removed via the "x".

In the lower view, the products per day can be defined for the individual products (4).

Before the production data is created, the total number of products that will be produced in a day is displayed (5).

Note: Production groups can be changed once they have been created.
