Tutorial: Creating Parameters in openLCA

For support visit http://ask.openlca.org/ Parameters - useful for sensitivity analysis - useful for preliminary data: data can easily be changed at the end of a study - different input values can create different versions of the life cycle - parameters reduce the likelihood of calculation errors - parameters can be used instead of concrete values for inputs/outputs - Define parameters as simple values, formulas or complex functions - one parameter can refer to others -- dependent parameters; loops not allowed - parameters can overwrite each other - available on different levels i.e. process, product system, project, impact method, database - local and global parameters possible - the amount of parameters is theoretically unlimited - Parameter names… … must be one word. … cannot contain special characters. … cannot have more than 255 characters. - Parameter formulas… … can contain single values, simple equations, or complex functions including logical expressions … do not contain units, so please add them in the comment field … cannot have more than 255 characters. ...must use a point instead of commaas a decimal - To check formulas you can use the formula interpreter to find errors To find out what constants, operators and functions are possible in openLCA, please see the document Parameter functions in openLCA: http://openlca.org/documents/14826/819ba7a7-88f2-4ce7-8651-3215f28c80be To download this description as a pdf: http://openlca.org/documents/14826/4ed70461-ef8d-4106-aea4-fe7494860c26 Follow openLCA: http://openlca.org @openLCA https://linkedin.com/groups?home=&gid=5060236&trk=my_groups-tile-grp To contact me directly: [email protected] or @SarahWWinter
