Abstract

Razvoj kompleksnih proizvoda potrebno je softverski podržati kako bi informacije o proizvodu bile strukturirane, pohranjene i dostupne dizajnerima koji s njima rade. Te funkcije ostvarene su PLM sustavima, no pokazalo se da PLM sustavi ne podržavaju dinamičko praćenje tokova parametara i komunikacijske procese u razvoju proizvoda. U ovom radu potrebno je kreirati model upravljanja konstrukcijskim parametrima u timskom radu pomoću Petrijevih mreža. Prije analize parametara razmatranih konstrukcija, proučena je literatura te su sažete najbitnije činjenice trenutnog stanja istraživanja. Procesi koji su modelirani su proces konstruiranja samohodnog uređaja za čišćenje prirubnice i proces konstruiranja Scara manipulatora. Razmatrani složeni proizvodi konstruirani su u timskom radu od dva člana. Relacije između parametara prikazane su u DSM matrici te je proveden algoritam particioniranja kako bi se vidjelo koji se parametri određuju sekvencijalno, paralelno i iterativno. Kao alat za modeliranje procesa pomoću obojenih Petrijevih mreža odabran je CPN Tools. Navedene su osnovne značajke alata. Kreirani su modeli za upravljanje parametrima procesa konstruiranja razmatranih konstrukcija uz model procesa komunikacije. Simulacije procesa moguće je pratiti uz korisnikov odabir izvršenja tranzicija ili automatski

Abstract (english)

The development of complex products needs to be supported by software so that product information is structured, stored and accessible to the designers who work with those information. These functions were realized with PLM systems, but PLM systems did not support dynamic parameter trails and communication processes in product development. In this paper, it is necessary to create a model of design parameters determination in team work using Petri nets. Prior to analyzing the parameters of the considered constructions, the literature was studied and the most important facts of the current research state were summarized. Processes that have been modeled are the process of design a self-propelled flange cleaner and the process of constructing Scara manipulator. Considered complex products are constructed in team work of two members. The relationships between the parameters are shown in the DSM matrix and a partitioning algorithm has been implemented to see which parameters are sequentially, parallelly and iteratively determined. CPN Tools is selected as a modeling tool for the Petri nets. The basic features of the tool are listed. Models for managing the parameters of the design process of the considered structures with the modeling of the communication process were created. Process simulations can be tracked with the user's choice of transition execution or automatically.
