Application of UML in plant modeling for model-based verification: UML translation to TNCES

On Controller and Plant Modeling for Model-based Formal Verification

“…Here are given main definitions: TNCES ={P,T,F,mo,yv,CN,EN,DC}(1) [1] {Cin ,Ein,Cout,Eot, Bc, Be, Cs, Dt} (2) [1] DC = {DR,DL,D0} (3) [1] TNCES,omposite = {M, CminP, Cm0Ut,Eninp,Emn0,Ic, Je} (4) [5] Figure 1 demonstrates the approach:. Tp is the function that translates UML diagrams to the TNCES [7]. Tc is the function that translates source code and controller information to the TNCES.…”

“…In the beginning [8], [6], we model the plant directly in TNCES, which was time consuming and error-prone process. We decide to utilize a higher-level language such as UML for modeling of the plant [7]. Despite the fact that UML can be considered as a higher-level language compare to TNCES, its expression power allows to model the same phenomena as the TNCES does.…”

“…One of the advantages in UML is that its diagrams allow modeler to concentrate on a specific feature of the plant. We identified three main aspects that has to be modeled [7], these are: * Structure/interface of plant components * Behavior of plant components * Interconnections of plant components and components themselves -objects To address abovementioned points, three UML diagrams are currently employed; these are respectively class diagrams, state charts and collaboration diagrams.…”

“…The automatic translation procedure of UML models composed of the selected diagrams is described in [7] and implemented in MNG.…”

“…1 1). Current syntax for plant model development with UML for automated translation to the TNCES is described in [7]. As can be seen in Figure 1, discretization problem involves representation of the each position of the pallet as a state in state chart.…”
