Cancel the product system creation: openLCA will stop the linking process at this point but will save the current state of the product system. The choice of system model is a responsibility of the user.
Continue with auto-select: openLCA will select the providers for this and all yet unhandled connections.
Select always the same provider for the respective flow (if the option Ignore default providers is active than this will also select the povider for the exchanges where another default provider is selected in the respective process, otherwise not).
Select a provider for the respective product input or waste output.
When the Check connections option is active and there are multiple providers for a product input or waste output a dialog with the following features will pop up:
The Provider linking options remain active and are considered in the connection checks.
If this option is selected the option with the Preferred process type is disabled (it is selected then manually).
Add an option Check connections to the auto-link options of the product system dialog.
#Openlca new product system no flow option update#
Add an ahead-of-time check for a process that provides linking statistics when this process is used as reference process of a product system (similar to the image below) -> update the product system statisticsĪdd an interactive user interface that can be used to select providers for product inputs and waste outputs during the creation of a product system:.
Are there product or waste flows with multiple providers in the database?.
Are there processes in the database where product inputs or waste outputs are not linked to a provider?.
In this case, the magnesia content of the. Because of the huge amount of processes and links in a system it is later hard to find such linking problems in the model graph.Īdd the database checks to identify the linking options that are applicable for a product system: In this section, a new calculation of the ReCiPe Midpoint (H) impact indicators is performed for this product system, assuming that in the recipe specified in Table 1 the component fused magnesia could be entirely substituted by DBM97, that’s to say by high purity magnesia, as described in. the co-product electricity of a waste treatment process is selected as the provider of the main electricity input of another process). This can lead to unexpected results (e.g. However, there can be multiple providers which are equivalent regarding these options in the database and openLCA just links the first best processes in this case. First of all we calculate all the new percentage for the different scenarios (reported. The auto-complete function in openLCA has several options for selecting the correct provider. Create a PRODUCT SYSTEM in OpenLCA called kWh CH and obtain the. For a product input in a process, there can be multiple processes that have this product as output (or for waste outputs, multiple waste treatment processes which take this waste as input). A product system in openLCA can contain thousands of processes and links between these processes.
