consistsOf
type: ObjectProperty
sub property of: topObjectProperty
domain: Process
range: Class
  union of: ProcessOperator
  union of: State
  union of: SystemLimit
comment: Describes containment of process elements (state, process operator, system limit) within a process

dependency
type: ObjectProperty
domain: State
range: State
comment: This ObjectProperty is not explicitly contained within the VDI 3682. It is used to describe dependencies of In- and Outputs. Due to open world assumption (OWA) the case that more than one In- or Outputs occur does always mean an alternative Input. For the case, that In- and Outputs are depending on each other, the ObjectProperty Dependency can be used. It can be interpreted as an "AND" constructor between In- and/or Outputs of a process. E.g.: A process has two Inputs. If they are alternatives, then this fact must not be explcitly modelled. If both Inputs have to go into the process, then the "Dependency" ObjectProperty is assigned between them. More complex example: Input A and B have to go into a process, while Input C and D are alternatives for A and B. The Inputs have to go as groups in the process. This equals: A AND B OR C AND D. The Dependency Operator is used between A and B as well as between C and D. Furthermore, the Operator can be used to express dependencies between In- and Outputs. If A and B are alternative Inputs that result in the Ouputs C for A or D for B then this equals: A AND C or D AND B. The ObjectProperty can be used between both, In- and/or Outputs.

flow
type: ObjectProperty
comment: most generic concept for flows taken from VDI3682 and refined by semantics that is used in graphical notation

hasInput
type: ObjectProperty
sub property of: flow
domain: Class
  union of: Process
  union of: ProcessOperator
range: State
comment: ObjectProperty that is used to link a ProcessOperator with an Input, i.e. Energy or Information or Product.

hasOutput
type: ObjectProperty
sub property of: flow
domain: Class
  union of: Process
  union of: ProcessOperator
range: State
comment: ObjectProperty that is used to link a ProcessOperator with an Output, i.e. Energy or Information or Product.

hasPredecessor
type: ObjectProperty

type: TransitiveProperty
domain: ProcessOperator
range: ProcessOperator
property chain axiom: hasInput
property chain axiom:
  inverse of: hasOutput
comment: an object property that is used to infer a predecessing relationship between entities

hasSubProcess
type: ObjectProperty
type: TransitiveProperty
domain: Class
  union of: Process
  union of: ProcessOperator
range: Process
property chain axiom: isComposedOf
property chain axiom:
  inverse of: consistsOf
comment: Is used to find the complete decomposed process of a process operatore. Note: This is syntactic sugar as a subprocess can be found by following "isComposedOf" and the inverse of "consistsOf".

hasSuccessor
type: ObjectProperty
type: TransitiveProperty
domain: ProcessOperator
range: ProcessOperator
property chain axiom: hasOutput
property chain axiom:
  inverse of: hasInput
comment: an object property that is used to infer a successing relationshipt between entities

hasUpperProcess
type: ObjectProperty
domain: Class
  union of: Process
  union of: ProcessOperator
range: Process
property chain axiom:
  inverse of: isComposedOf
property chain axiom:
  inverse of: consistsOf
comment: Is used to find the parent (upper) process of a lower level process operator. Note: This is syntactic sugar as a parent process can be found by following the inverse of "isComposedOf" and the inverse of "consistsOf".

isAssignedTo
type: ObjectProperty
domain: ProcessOperator
range: TechnicalResource
comment: ObjectProperty that is used to indicate that a process operator is performed by a technical resource.

isComposedOf
type: ObjectProperty
domain: ProcessOperator
range: ProcessOperator
comment: Used for decomposition. A process operator can be composed of multiple more detailed process operators.

longName
type: DatatypeProperty
type: FunctionalProperty
comment: A property that is used to give a long name to an individual.

shortName
type: DatatypeProperty
type: FunctionalProperty
comment: A property that is used to give a short name to an individual.

Energy
type: Class
subclass of: State
comment: Energy is requiered by the process operator to fullfill the process. Energy is Input and Output of a process. Energy can be any kind of energy, exp.: electricity, heat,...

Information
type: Class
subclass of: State
comment: Information input for a process operator can be any kind of information required to fullfill the process. Information output can be any kind of information created by the process. [VDI 3682-1]

Process
type: Class
disjoint with: State
disjoint with: SystemLimit
disjoint with: TechnicalResource
comment: A process describes the desired behavior of a process operator, by means of a solution neutral description of inputs and outputs. Products,energies and information are converted into new products,energies and information by a process operator. The process operator implements this conversion with the help of technical resources. [VDI3682-1] Note that a process may have inputs and outputs. These are inputs / outputs that are on the system limit of this process.

disjoint with: TechnicalResource
comment: One step of a process that transfers a status "before" (i.e., an input) to a status "after" (i.e., an output). Everything that has an input and an output may be a process operator (but could also be a process). Everything that has an input and an output AND is contained within a process is a process operator.

Product
type: Class
subclass of: State
comment: A rather generic concepts to describe all sorts of raw, intermediate or final products. Can also be used to describe flow of materials. [VDI 3682-1]

State
type: Class
disjoint with: SystemLimit
disjoint with: TechnicalResource
comment: A State describes the actual state of a Product/Energy/Information. Exp.: status ante operationem and status post operationem. [VDI3682-1]

SystemLimit
type: Class
disjoint with: TechnicalResource
comment: The system limit determines the observation horizon of the process. In a broader sense, this can also be seen as the balance limit for incoming products/energy/information and outgoing products/energy/information. [VDI 3682-1]

TechnicalResource
type: Class
comment: The technical resource is able to implement certain processes and is an abstract description of a system. [VDI 3682-1]
