@HeddaElisabethGardian what do you think about this definition:
We also need definitions for the following terms:
Investment costs: Capital investment costs means costs, beyond the research and development phase, associated with capital improvements, including the acquisition and development of land, the design and construction of new facilities, and the making of renovations or additions to existing facilities.
Fixed operation and maintenance costs: A company's fixed costs are costs for operation and mantainance that do not vary with the volume of production. Fixed costs remain the same regardless of whether goods or services are produced or not. Thus, a company cannot avoid fixed costs.
Delivery costs (for materials, energy carriers): Delivered costs for a product or service refer to the total unit cost of a product or commodity delivered to a certain market, city or customer. It is normally composed of all associated transport costs and the unit cost of production. for that product.
We could even use subclasses of cost subclasses here for some terms:
Cost of Equipment
and Cost of grid connection
could be subclasses of investment costs
.
Cost of rent of land
could be a subclass of fixed operation & maintenance costs
.
From OEO-DEV #28:
General Discussion
Variable cost
Label parent class: Variable cost
Decision: not yet continue with including variable consumption cost, rather focus on production for the time being and see whether consumption-related information is required at a later stage.
Definition: Variable costs are costs that depend on an amount of goods or services.
Production
Variable production cost
Consumption
Variable consumption cost
Decision: not yet continue with including variable consumption cost, rather focus on production for the time being and see whether consumption-related information is required at a later stage.
I implement variable cost
and variable production cost
. I won't close the issue und shift it to a later milestone.
Does the definition "Variable costs are costs that depend on an amount of goods or services." include the variable costs for a technological device running? Is for example the production of electrical energy by a wind turbine a "service" provided? If yes, then the definition is correct in my option.
I think, electrical energy
should get the axiom 'has role' some 'commodity role'
, then this would be covered by the definition of variable cost
.
Concerning the other cost terms, here is a suggestion for a definition:
Investment costs: Investment costs are costs, beyond the research and development phase, associated with capital improvements, including the acquisition and development of land, the design and construction of new facilities.
Fixed operation and maintenance costs: Fixed costs are costs for operation and mantainance that do not vary with the amount of goods or services produced.
Equipment costs: Equipment costs are costs for the components and machinery including environmental facilities.
Grid connection costs: Grid connection costs are costs of grid connection from the energy generating device to point of connection to national grid.
Rent of land costs: Rent of land costs are costs arising from the land rental on which a technological device has been constructed.
Decommissioning costs: Decommissioning costs are costs arising from the decommissioning of a technological device at the end of its lifetime.
Decisions from the oeo-dev-meeting:
Investment cost
parent: cost
Definition: Investment is a long-term commitment of financial resources in tangible or intangible assets.
Alternative term: investment cost, capital investment cost, fixed investment cost_
Background info: FIBO definition of investment relates to property only: https://spec.edmcouncil.org/fibo/ontology?searchBoxQuery=investment
Gabler on Investition: langfristige Bindung finanzieller Mittel in materiellen oder in immateriellen Vermögensgegenständen (https://wirtschaftslexikon.gabler.de/definition/investition-39454) translation: long-term commitment of financial resources in tangible or intangible assets
Fixed cost:
parent: cost
Definition: Fixed costs are costs for operation and mantainance that do not vary with the amount of goods or services produced.
Examples: rent, regular technical maintenance cost, staff cost, certification cost
alternative terms: fixed operation & maintanance cost
Background: Fixe Kosten: Kosten, die von der jeweils betrachteten Einflussgröße bzw. Entscheidung unabhängig sind, d.h. Kosten, die sich nicht mit der jeweils betrachteten Einflussgröße ändern. (https://wirtschaftslexikon.gabler.de/definition/fixe-kosten-33359)

Still open for discussion:
Equipment cost:
parent: investment
Definition: Equipment costs are investment costs for acquisition of the components and machinery including environmental facilities.
Installation cost:
Grid connection cost:
Property cost:
Decommissioning cost:
Still open: Finding axioms
Does anybody have an idea for some axioms or want to change definitions? I would like to implement.
I would also need the cost subclass delivery cost
as a model parameter for our model. There is a definition proposal posted already above:
Delivered costs for a product or service refer to the total unit cost of a product or commodity delivered to a certain market, city or customer. It is normally composed of all associated transport costs and the unit cost of production for that product.
A suggestion for an Arestotelian definition would be: Delivery costs are costs for a product or service that refer to the total unit cost of a product or commodity delivered to a certain market, city or customer. It is normally composed of all associated transport costs and the unit cost of production for that product.
Would an appropriate axiom be "has unit some currency" and "has unit some unit of measurement"?
I think the axiom has unit some currency
would be appropriate, but since unit of measurement
is the parent class of currency
, the second axiom is not necessary in my view
For the term "social cost of carbon" both axioms are listed, but you are right the parent class is redundant.
All subclasses of unit of measurement
inherit has unit some unit of measurement
by the parent class, as well as all subclasses of cost
inherit the axiom has unit some currency
automatically.
Decisions from the oeo-dev-meeting:
Investment cost
- parent: cost
- Definition: Investment is a long-term commitment of financial resources in tangible or intangible assets.
- Alternative term: investment cost, capital investment cost, fixed investment cost_
We should not mix up "investment" and "investment cost". "Investment" seems to be the process of investing, whereas "investment cost" refers to the cost of this process.
In this case you want to implement investment cost
, as you made it a subclass of cost
, right? This should be reflected in the definition. Hence, I'd label it investment cost
and make investment
alternative term.
Maybe it's sensible to implement both investment cost
and a process investment
. @l-emele ?
In that case, we should add an axiom like 'investment cost' 'economic value of' some 'investment'
Maybe, I do not understand this definition proposl. But to me, the concept described with the current definition proposal (Investment is a long-term commitment of financial resources in tangible or intangible assets.) is neither a subclass of a cost
nor of a process
. A long-term commitment is to me a commitment to either do something in the far future or for a long time. In the definition proposal the reference to the indented parent concept (cost
) is missing completely.
The proposed def can't be used since it's not Aristotelian (as long as we don't have "long-term commitment") and I didn't suggest to do so. I intended to feaze the mixed up concepts, but maybe it's easiest to just focus on the cost part.
EDIT: Easy suggestion: Investment costs are costs of a long-term commitment of financial resources in tangible or intangible assets.
Description of the issue
There are multiple terms to distinguish costs:
