[pt] A modelagem de sistemas que apresentam subsistemas idênticos, por intermédio de Redes de Petri, conduz à geração de grafos de grandes dimensões com diversos componentes indênticos. As extensões às Redes de Petri que permitem diferenciar estes diversos subsistemas, por intermédio da distinção das fichas nelas contidas, receberam o nome de Redes de Petri Coloridas. Neste trabalho, são apresentados algumas propostas existentes na literatura sobre Redes de Petri Coloridas, bem como é desenvolvido um programa de análise baseado em uma dessas propostas - a de kurt Jensen. O programa analisa as propriedades de uma Rede de Petri Colorida, tais como limitação, vitalidade e capacidade de reinicialização, através do método de enumeração de marcações. / [en] The modeling of sistems which have identical sub-systems, by means of Petri nets, leads to the generation of large scale graphs with identical components. The extensions of Petri nets, which afford the possibility of distinguishing these sub-systems through the distinction of the tokens within the net, are called colored Petri nets. This work presents some colored Petri net proposals existent in literature and an analysis code based on one of these proposals - the Kurt Jensen one. This program analyses through the mark enumeration method, the colored Petri net properties, such as boundedness, liveness and reinicialization.

In the final work it is made analysis of Petri nets and Petri nets simulators, analysis of modeling system composition and its methodology. There were presented topicality of theme, it’s practical and theoretical meaning, work purpose and tasks. There was made analysis of Petri net simulator on DSP and was made realization of Petri net on DSP. Presented conclusions of the final work, therefore it was mentioned practical results.

This work is dedicated to the making and research of mobile information system. Following tasks were completed in order to tackle this problem: mobile information system processes analysis; uml modeling analysis; formal modeling methods analysis; composition of system model; system model verification.

Among the technologies that stand out today in this area there are Wireless Sensor Networks and Radio Frequency Identification Networks, which are being used together to monitor and identify objects and people. Within the scope of Ubiquitous Computing, there are Ubiquitous Laboratories (u-Lab) which are laboratories that have sensing, provision of software services to support the user, support to the performance of activities, among other characteristics. In order to offer support to practices performed in Ubiquitous Laboratories a framework called Ubiquitous Laboratory for Practical Activities (u-LabPA) was created, which allows students to collect data from laboratory activities and to access them later in the form of simulations or virtual environments. In this work we perform the formal modeling and simulation using Colored Petri Nets (RdPC), as well as the analysis of the results of the requisits "Authentication", "Register Activity", "Register User Activity", “Provide User Activities”, "Perform Activity", present in the u-LabPA framework. The results of this analysis reveal that the activity flow of the u-LabPA framework met its basic requirements as well as the stress tests for which it was submitted, maintaining its consistency and its behavior within the expected spectrum. / A Computação Ubíqua é uma área que relaciona tecnologias e conceitos como Pervasividade, Mobilidade, Adaptabilidade e Aplicações Orientadas à Localização. Dentre as tecnologias que se destacam hoje nesta área, têm-se as Redes de Sensores Sem Fio e de Identificação por Radiofrequência, que estão sendo usadas em conjunto para monitorar e identificar objetos e pessoas. Dentro do escopo da Computação Ubíqua, existem os Laboratórios Ubíquos (u-Lab) que são laboratórios que possuem sensoriamento, provimento de serviços de software de apoio ao usuário, apoio a realização de atividades, dentre outras características. A fim de dar suporte às práticas realizadas em Laboratórios Ubíquos foi criado o framework chamado Ubiquitous Laboratory for Practical Activities (u-LabPA), que permite a alunos colherem dados de atividades laboratoriais e acessá-los a posteriori na forma de simulações ou ambientes virtuais. Neste trabalho é feita a modelagem formal e simulação em Redes de Petri Coloridas (RdPC), bem como a análise de resultados dos requisitos “Autenticação”, “Cadastra Atividade”, “Registra Atividade de Usuário”, “Disponibiliza Atividades de Usuário” e “Realiza Atividade”, presentes no framework u-LabPA. Os resultados desta análise mostram que o fluxo de realização de atividades do framework u-LabPA atendeu a seus requisitos básicos bem como aos testes de estresse para o qual foi submetido, mantendo sua coerência e o seu comportamento dentro do esperado.

A personal process is a coordination of personal activities, each requiring a joint effort between a user and an enacting organization. In this thesis, we model a personal process using Petri Nets to describe both the control flow and data flow pertaining to the personal process. We redefine the correctness of a personal process and address the verification method based on Petri Nets. In our architecture, we add an online execution engine for the user to execute and verify the correctness of a personal process in real time¡@through the Internet. A personal process can also be managed by a personal workflow management system (PWFMS) running on a handheld device. Because of the strict limitations on their computation power and battery consumptions, we support verification only when the wireless connection is available.

Petri nets are named in honor of Dr. Carl A. Petri for his famous Ph.D dissertation of general net theory in 1962. A substantial amount of work utilizing and modifying the Petri nets has been done since then, and they have turned out to be very useful in the study of asynchronous concurrent systems. The liveness and reachability problems are considered to be some of the major problems in Petri net theory.Since the structure of a Petri net can be regarded as sets of places and transitions form a graphical point of view, this thesis is concerned with utilizing the results of graph theory to investigate the liveness in terms of deadlock problems of a special subclass of Petri nets, free-choice Petri nets. As a subclass of Petri nets, the class of free-choice Petri nets possesse relatively strong analysis properties. This is especially true of complete free-choice Petri nets. We show in particular that any system which can be modeled by a general Petri net can also be modeled by a free-choice Petri net. / Department of Computer Science
