Abstract

U ovom magistarskom radu predstavljene su prednosti korištenja novih tehnologija baziranih na Internetu, te su predstavljene suvremene metode analize i sinteze u upravljanju fleksibilnim proizvodnim sustavima. U svrhu modeliranja i analize fleksibilnih proizvodnih sustava primijenjen je matrični model, jer je upravljački algoritam dobiven primjenom matrične algebre direktno pretočiv u kôd za programirljive logičke kontrolere. U sklopu magistarskog rada izrađena je web-aplikacija FlexMan, koja... More omogućava jednostavan način kreiranja složenih fleksibilnih proizvodnih sustava korištenjem virtualne stvarnosti i matričnih modela. Zasniva se na klijent-server arhitekturi, koja povezuje komponente koje uključuju: Scene Builder – alat za kreiranje virtualnih modela FPS-a i izgradnju matričnog modela sustava; Visualization Client – alat za prikaz rezultata simulacije FPS-a; Web Trajectory Planner – sučelje prema LEONARDO-u, alatu za offline planiranje trajektorija; Bazu korisnika i modela – to su pohranjene informacije o korisnicima i modelima; FMS Controller – središnja komponenta, koja obrađuje zahtjeve klijenata i obavlja simulaciju FPS-a. Korištenjem FlexMan-a izrađeni su virtualni i funkcionalni modeli nekoliko različitih primjera fleksibilnih proizvodnih sustava, te su njihovom simulacijom u virtualnom okruženju zorno prikazani fenomeni kao što su konflikti i zaglavljenje. Takav alat omogućava da se riješe svi uočeni problemi prije izgradnje realnog sustava. Less

Abstract (english)

This Master thesis presents modern methods for analysis and synthesis in the control of flexible manufacturing systems, along with advantages of using new Internet-based methods. A matrix model is used for modeling and analysis of flexible manufacturing systems, because the control algorithm obtained with matrix algebra is directly transferable into PLC code. A web-application named FlexMan was developed in the scope of this Master thesis. FlexMan provides an elegant and simple way for... More designing flexible manufacturing systems by using virtual reality and matrix models. It is based on client-server architecture which links its components like: Scene Builder – a tool for creation of virtual FMS models and definition of the system matrix model; Visualization Client – a tool for displaying the results of FMS simulation; Web Trajectory Planner – an interface to LEONARDO – tool for off-line trajectory planning; Database – stores the user information and model libraries; FMS Controller – the heart of FlexMan which processes client requests and performs FMS simulation. Virtual and functional models of various FMS examples were built using FlexMan, and by simulating their behavior in a virtual environment, the phenomena like resource conflict and system deadlock were clearly presented. A tool like FlexMan enables detection and solution of such problems before building the actual real-world system. Less
