ObjectProperty that is used to indicate that a process operator is performed by a technical resource.
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.
a downflow occurs whenever one tries to follow an entity down the value stream to the end of production
most generic concept for flows taken from VDI3682 and refined by semantics that is used in graphical notation
as the formalized process description does not classifiy processes, products or other entities, this relation can be used to indicate inheritance
ObjectProperty that is used to link a ProcessOperator with an Input, i.e. Energy or Information or Product.
ObjectProperty that is used to link a ProcessOperator with an Output, i.e. Energy or Information or Product.
an object property that is used to infer a predecessing relationship between entities
ObjectProperty that is used to describe the state of a process via the state of products, energies and information.
ObjectProperty that is used for decomposition of process operators.
an object property that is used to infer a successing relationshipt between entities
Objectproperty that is used to assign an In- or Output to be coming from outside of the system boarder.
ObjectProperty that is used to indicate that a process operator is within a certain system boarder.
an upflow occurs whenever one tries to trace from a starting point up the value stream to the beginning of production
A property that is used to give a long name to an individual.
A property that is used to give a short name to an individual.
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 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]
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]
A State describes the actual state of a Product/Energy/Information. Exp.: status ante operationem and status post operationem. [VDI3682-1]
The system boundary 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]
The technical resource is able to implement certain processes and is an abstract description of a system. [VDI 3682-1]
