Uma extensão de rede de petri para modelagem de processos e controle de projetos.

Abstract

Frequently in the development of projects occurs waste of resources, defects and missing deadlines. In the software development area this issue becomes more significant, where complex projects are developed with difficulty, although techniques, models and traditional tools for project management are popular. Deadlines always are extended and the cost of software being developed gowns significantly. The traditional models of project management don‘t fit very well to large projects with a short schedule. The actual project management tools do not cover the track of both processes (times, costs, resources and activities) and software projects. The actual software development methodologies represent many advances to assist a manager into a software development process, but it lacks a more adequate use of them, in accordance with the specific complexity of the type of application being developed and its characteristics. This work is centered in the extension of a net for project management, called Activities Net, designed to track detailed information about the development of processes and projects, calculate and update costs, allocate human resources and schedule activities. This net is the main component of an integrated environment for project development management, called GDP, based on a four-layer approach: (1) determine de best methodology; (2) model the metodology; (3) model the project; (4) execute the project. In order to determine the structural quality of an Activities Net and allow simulations and correct cost a time calculations, a special class of Petri Nets has been developed, called Project Net (NP). Also the mapping of an Activities Net to a Project Net has been defined.
