Graphical Editor for Design Models
Hlavačka, Filip ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
The thesis is aimed at the solution of graphical editing for design models, especially Object-oriented Petri nets. There are many tools for editing Object-oriented Petri nets, but none of these support complete cooperation with simulation classes. This thesis offers created tool, which is implemented in the Pharo environment and uses the Morphic library. The created tool enables users to create or modify Object-oriented Petri net. Users can export created net to SVG or PNG format. The tool also enables the saving and loading of Object-oriented Petri net. The tool provides syntax check to the user.

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.

Object Oriented Petri Net Tool
Neužil, Antonín ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
This work deals with the development and use of a graphical editor of object-oriented Petri nets implemented in the PNtalk language. First, Petri nets that expand over time are described here. They are followed by a description of the object-oriented paradigm. Next, the structure of object-oriented Petri nets in the implementation of PNtalk is described here. Further work presents a description of the application design, which shows the entire structure of the application from the perspective of views. The main motivation for creating this tool is the effort to make object-oriented Petri nets accessible to their users. The application was implemented in the JavaFX framework and the whole procedure is given in the following chapter together with testing. The result of the work is presented in the examples contained in the last chapter, which also contains detailed manuals for controlling the application. The tool in cooperation with the PNtalk server enables users to work more pleasantly with OOPN and their visual appearance.

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.

OOPN Editor
Neužil, Antonín ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
This bachelor thesis deals with Petri nets and their modeling. First of all, the thesis describes the formalism of the Petri network. It will also focus on object orientation of networks. In the second row, the thesis is specialized on the created application and it is a graphical editor of object-oriented Petri nets. Part of the thesis is the process of designing and implementing the already mentioned application. The application is created using programming language Java and is compatible only with operating system Windows. NetBeans IDE 8.0.2 development environment was used to create the application. The result of the whole bachelor thesis is an application for creation of models of object-oriented networks and their simulation with the attached server. Several examples of these models and their results are part of this thesis. These examples serve as an application manual.

The Tool for Object Oriented Petri Nets
Josefík, Martin ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
This thesis deals with creation of the tool for Object Oriented Petri Nets which uses two different languages PNML and PNtalk. PNML is an XML-based interchange format for Petri nets. Its advantage is that it is possible to describe each element of Petri net by element of PNML language. PNtalk is based on the formalism of Object Oriented Petri Nets and also on Smalltalk language. The tool for OOPN will communicate with the external application PNtalk system in order to exchange models between these two applications. There will be discussed possible extensions for the tool at the end of the thesis.

Simulation and Design of Intelligent Agents
Šperka, Svatopluk ; Rozman, Jaroslav (referee) ; Janoušek, Vladimír (advisor)
Conventional method of development which repeats phases of design, implementation and testing is not adequate for systems like intelligent agents for which complex behavior is required but specification is unclear at the beginning of development process. Incremental design of agent's model during simulation seems more suitable for it enables direct feedback in behavioral changes of a system. This interactivity speeds up development process and helps to uncover parts of a space of all models to designer - thanks to new knowledge acquired during simulation. This thesis aims to provide comparison of suitability of two agent architectures and respective platforms in context of SmallDEVS modeling and simulation framework for this methodology of development. First approach is reactive and decentralized subsumption architecture based on DEVS formalism and the second one is PNagent, framework realizing deliberative BDI architecture using Object Oriented Petri Nets.

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.

Petri Nets Patterns Library
Hanák, Martin ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
This thesis concerns creating models using formalism of Object Oriented Petri Nets (OOPN). It concludes with various usability of such formalism and in the second part of the thesis it indentifes useful and often repeated patterns of OOPN. These patterns are strongly inspired by classic programing languages, mainly by constructions concerning data manipulation and program flow control. Indentified patterns describes options for modelling these construction in OOPN.

Interpreter of Petri Nets Formalism
Šajdík, Ondrej ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
The goal of bachelor thesis was to create tool which would be able to interpret Object-oriented Petri nets. In theoretical part was researched Petri nets, its simple extensions, Object-oriented Petri nets and modeling in language PNtalk. In practical part of thesis was designed and implemented tool for loading model defined in language PNtalk into inner representation and executing its dynamics. In the end was created set of automated tests for quality assurance and group of models for demonstration of interpret features.
