1. IDEF3 PROCESS FLOW
Un modello di processo IDEF3 descrive ciò che un sistema fa (per esempio un Sistema
di gestione per la Qualità). Questo modello cattura I vincoli del sistema, quali le risorse
ed i legami temporali.
Gli elementi di base per la descrizione di un diagramma IDEF3 Process Flow sono:
• UOBs
• junctions
• links
• referents
• decompositions
• matrices

DEFINIZIONI
1. UOB’s (Units of Behaviour)
È un termine utilizzato per descrivere diversi tipi di “accadimenti”. Concetti come funzione,
processo, scenario, attività, operazione, decisione, azione, evento, procedura, ecc.,
rappresentano “accadimenti” che implicano una qualche forma di “comportamento”
(behaviour) circoscritto.

3. Link
È un elemento sintattico di un diagramma IDEF3 usato per connettere altri elementi del
diagramma. I links denotano le correlazioni significative tra UOB’s, object states e objects.
Esistono tre tipi di link:
• Precedence Link
• Relational Link
• Object Flow Link
3.1 Precedence Link
Rappresenta semplicemente una precedenza temporale tra l’attivazione (instance) di una
UOB e quella di un’altra.

3.2 Relational Link -- (chiamato anche “user-defined link”)
Denota l’esistenza di una correlazione ”user-defined” tra due o più UOB’s. Vale la tabella
precedente.
3.3 Object Flow Link
Denota la presenza di un oggetto (object) nell’attivazione di due UOB’s e implica inoltre un
vincolo di precedenza.

Decomposition is the act of breaking a system into its component subsystems, processes,

IDEF3 Object State Transition Network (OSTN Diagrams)
An Object State Transition Network (OSTN) diagram is used to model the behavior of an
object as it transitions from state to state, based on events. You may specify what object
the OSTN diagram shows behavior for, in the OSTN diagram properties.

1. Transitions (Dictionary Object)
Transitions represent allowable changes between states. One of the first steps in the
development of an Object State Transition Network (OSTN) is to identify all possible states
in which the object can exist. Though a real-world object often evolves through a
continuum of states, an OSTN diagram focuses on those distinguished states that are of
particular interest to the domain expert. For each of these states, the OSTN diagram
supports the specification of:
• the conditions that characterize the state
• the conditions that will permit a transition into the state (entry conditions)
• the conditions that need to hold for the object to transition out of the state (exit
conditions
