Model Based Design of the Conference System
Caha, Matěj ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
This thesis deals with the topic of model-based design and application of simulation in system design. In the introduction, the thesis discusses the history of software development process and outlines the current status. The aim is to demonstrate a model-driven design on a case study of conference system. There will be presented formalisms of DEVS and OOPN together with experimental tools PNtalk and SmallDEVS that allow to work with these formalisms. The resulting model of conference system will be deployed as part of a web application using a framework Seaside in the Squeak environment.

Code Generation from Object Oriented Petri Nets
Cibák, Michal ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
The goal of this thesis is to analyze the current solution of a code generator from Object oriented Petri nets written in PNTalk language to Java language, propose changes and implement them. First the overall scheme was analyzed and missing parts were specified, then the source code of the compiler was analyzed and errors were found. The proposed corrections of errors in the compiler were made and some missing parts from the scheme were partially implemented within the compiler.

Process Control with Dynamic Resource Scheduling
Šinkora, Jan ; Kočí, Radek (referee) ; Janoušek, Vladimír (advisor)
This project pursues issues on the border of information technologies and process optimization. Previously published concepts of~modeling projects and shared resources with object-oriented Petri nets are presented and further expanded. The possibilites of~the use of~genetic algorithms for dynamic realtime optimization of the resource schedules are explored. The resource constrained project sheduling problem is presented and it is shown, how instances of the problem can be implemented. A more complex model that is inspired by real production systems is then created. Next, a control agent, which monitors a running production system and allows for it's dynamic optimization is designed. The whole system is implemented in the Squeak Smalltalk environment with the use of the tool PNtalk, which is an experimental implementation of the object oriented Petri nets paradigm.

Graphical Editor for Design Models
Švub, Daniel ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
The target of this thesis was a design and a development of an user friendly graphical editor of Object oriented Petri nets (OOPN). For description of this formalism was used PNtalk language, which combines Petri nets with the object oriented language Smalltalk. The resulting application should allow users to design object and their behaviour via OOPN and simulate directly in the editor.

Sequence Diagram Generation from Object-Oriented Petri Nets
Hoffmann, Michael ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
This diploma thesis aims to design and implement the mechanism of transformation of Object Oriented Petri Nets (OOPN) models into the form of sequence diagrams, as they are defined in the UML language. The OOPN formalism combines object-oriented language Smalltalk and Petri nets and is described by the PNtalk language. The resulting implementation will become part of the existing editor of Object-oriented Petri nets, where it will be possible to generate a sequence diagram from edited models.

Code Generation from Object Oriented Petri Nets
Cibák, Michal ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
The goal of this thesis is to analyze the current solution of a code generator from Object oriented Petri nets written in PNtalk language to Java language, propose changes and implement them. First the overall scheme was analyzed and missing parts were specified, then the source code of the compiler was analyzed and errors were found. After implementing the fixes for these errors, it was proposed to modify the compiler and simulator such that the missing functionality was supported. These changes were implemented.

Sequence Diagram Generation from Object-Oriented Petri Nets
Beňo, Adam ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
The thesis focuses on the issue of sequence diagram generation from scenarios modelled by object-oriented Petri nets (OOPN). It aims on module implementation into existing OOPN editor which enables showing sequence diagrams from individual simulations and is connected with simulated model. The user thus gets complete overview of the simulation process and is able to detect errors in OOPN models.

Sequence Diagram Generation from Object-Oriented Petri Nets
Bláha, Jiří ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
The goal of this bachelor's thesis is to design and create an application that graphically represents the communication between objects during a simulation of object oriented Petri nets (OOPN) as sequence diagrams. Input to the application is the definition of OOPN classes written in PNtalk. A simulation server, implemented in SmallTalk, is used for OOPN model simulation. This thesis describes server commanding and corresponding data retrieving as well as its transformation to a form suitable for sequence diagram generation and drawing. The implemented solution allows users to save the final sequence diagram as a PNG, SVG or XML file for further result sharing and processing. The application simplifies working with the simulation server, which otherwise doesn't incorporate any form of human-readable output and, therefore, it allows users to quickly and easily determine the order of events inside the simulated model.
