Processes

Here you find information about the following topics:

Insert Process

  2. On the Drawing Area, drag-and-drop your pointer to draw a process or click the position where you want to insert a process with predefined size.

Select Process

  1. On the Shapes window, click  to switch to the edit mode.
  2. On the Drawing Area, click a process.

Move Process

  1. Select a process.
  2. Drag-and drop the process to its new position.

Delete Process

  1. Select a process.
  2. On the Diagram toolbar, click or press Delete.

Rename Process

  1. Select a process.
  2. On the Properties window, select the Process tab.
  3. Enter short symbol, name and remarks (general information about the process).

Set Process Caption

  1. On the Extras menu, select Options and click the Processes & Flows tab.
  2. On the Process pane, select the type of process label caption (short symbol and/or name)
  3. Process List
Note:

Change Process Type

You can define a process with stock, without stock or as subsystem.

  1. Select a process.
  2. On the Property window, select the Process tab.
  3. Set or delete a tick in the desired checkbox (subsystem, stock, TCs).

Note:

Change Process Color

  1. Select a process.
  2. On the Properties window, select the Shape tab and choose the desired process color.

Toggle Anchor Points

Notes:

Change Process Size

  1. Select a process.
  2. Drag-and drop one of the green handles on the perimeter of the process to the desired position.

Notes:

Set Default Process Size

  1. On the Extras menu, select Options and click the Defaults tab.
  2. On the Process pane, enter default width and height of a process in mm.
  3. Click OK or Apply.

Note:

Edit Subsystem

This is only possible if the process has been defined as subsystem.

  1. Double click a subsystem.

or

  1. Select a subsystem.
  2. On the Edit menu, select Edit Subsystem or use the context menu (right click) of the subsystem.

Notes:

Edit Transfer Coefficient

Transfer coefficients can only be entered if the process is no subsystem and contains no stock.

  1. Double click a normal process (without stock and subsystem)

or

  1. Select a process without stock.
  2. Right click the process and choose Edit Process from its context menu
    or
    On the Edit menu, select Edit Process.
    or
    In the Property window select the tab TC and click Edit

    In the Process dialogue window on the tab TC you see a given matrix where you can enter transfer coefficients with respect to the sum of inputs or single inputs.
  3. Enter transfer coefficients directly into the fitting cells. You can choose between two different ways: a number between 0 and 1 (e.g. 0.6) or a percentage number (e.g. 60%).
  4. To enter data uncertainties of transfer coefficients (in form of standard deviation of an assumed normal distribution) write +- directly after the mean value and enter the absolute value of the standard deviation (e.g. 0.60+-0.06 or 60%+-6%).
  5. Alternatively click the ... button to open an edit dialogue. Only there it is possible to enter literature and remarks.
  6. Click OK or Apply.

Notes:

Enter Stock/Change in Stock and/or Concentration

This is only possible if the process includes a stock.

  1. Double click a process with stock.
  2. Select tab Stock/dStock.
  3. Enter a value in one of the text fields (mean value an optional uncertainty).
  4. If you want use another unit than the displayed one enter it directly after the number (e.g. 100 kg/a) or click the unit button to choose from predefined units.

 

or

  1. Select a process with stock.
  2. In the Property window select tab Stock/dStock.
  3. Enter a value in one of the text fields (mean value an optional uncertainty).
  4. If you want use another unit than the displayed one enter it directly after the number (e.g. 100 kg/a) or click the unit button to choose from predefined units.

Notes:

  1. On the layer of goods you can enter optionally mass/mass flow, volume/volume flow and/or density.
  2. On the layer of substances you can enter optionally mass/mass flow and/or concentration (mass substance per mass or volume good respectively).
  3. On the layer of energy you can enter optionally energy/energy flow and/or concentration (energy per mass or volume good respectively)
  4. If you want to consider data uncertainties you can enter the range of uncertainty in form of the standard uncertainty in the data field right of the +- sign. The data set will be interpreted as mean value and standard uncertainty of an assumed normal distribution.
  5. Uncertainties can also be entered in percent if a mean value is already given (e.g 10%). The entry will be automatically transformed into an absolute value.
  6. By default entered data will be displayed optionally with a maximum of 2 digits after the comma. I.e. if the number has more than two digits after the comma it will be displayed rounded.

Display Process List

A process list shows a list of all processes with their input and output flows.

  1. On the Edit menu, click Process List.
  2. Click  to export the process list as Excel 2003 file.

Notes:

Document Stock Values

The documentation of data is an essential point when performing a MFA. Because of that each stock/change in stock value can be documented for each layer and period separately with respect to literature reference and additional notes.

  1. Select a process with stock.
  2. In the Property window select tab Info (values).
  3. Enter a new literature reference under Literature reference (and click on any other text field in the property window afterwards) or select an already defined one from the dropdown list.
    If you have entered a new reference you will be asked if you want to create a new reference. Choose Yes to make this reference available as template in the dropdown list for future documentation work.
  4. Enter Remarks.
