- Avaliação e acompanhamento de projetos de I&D numa empresa de telecomunicaçõesPublication . Fialho, Joana; Godinho, Pedro; Costa, João Paulo; Afonso, RicardoNeste capítulo, apresenta-se uma solução para a avaliação e seleção de projetos de Investigação e Desenvolvimento (I&D) de uma empresa de telecomunicações (a PT Inovação), bem como o processo que a ela conduziu. A empresa dedica-se, por excelência, à inovação, investigação e desenvolvimento, pelo que uma correta alocação de recursos, baseada num modelo de avaliação das diferentes propostas com que a empresa se depara, é fundamental para que possa prosperar. No entanto, a avaliação deste tipo de projetos apresenta dificuldades específicas de índole diversa, e deve também ser devidamente enquadrada na política da empresa, pelo que se entendeu ser desejável definir uma solução de raiz, em vez de se optar por modelos predefinidos. A solução resulta de um processo iterativo que envolveu, por um lado, um conjunto de investigadores das áreas das finanças e investigação operacional e, por outro, vários elementos da empresa. A solução tem por base a avaliação comparativa das propostas com que a empresa se depara, e parte daí para a alocação de recursos entre os projetos selecionados. Os recursos mais importantes desta empresa são as pessoas, e a solução definida permite orientar os decisores relativamente à alocação das pessoas aos projetos
- A Level-Based Approach to Prioritize Telecommunications R&DPublication . Fialho, Joana; Godinho, Pedro; Costa, João Paulo; Afonso, Ricardo; Regalado, José GonçaloIn this paper, an approach to evaluate R&D projects in telecommunications is presented. These projects have particular features that cannot be properly incorporated by classical valuation methods. This approach incorporates different criteria, both quantitative and qualitative, and also management flexibility and uncertainty. Thus, it is an approach that can be applied to real data of R&D projects in a telecommunications company.
- Some issues about the application of the analytic hierarchy process to R&D project selectionPublication . Godinho, Pedro; Costa, João Paulo; Fialho, Joana; Afonso, RicardoThe analytic hierarchy process (AHP) has been used in the process of selecting research and development (R&D) projects. Such a selection process usually possesses some particular features that require adjustments in the application of the AHP method, such as the existence of a large number of very different alternatives or the integration of qualitative and quantitative criteria. In this paper, we discuss the application of AHP to the selection of a portfolio of R&D projects, and we propose some methods for handling the issues that arise from such an application
- A Stochastic Model for Managing Tasks of R&D ProjectsPublication . Fialho, Joana; Godinho, Pedro; Costa, João PauloIn this paper, we propose a model for managing tasks of R&D projects. We assume that di®erent amounts of resources may be allocated to a task, leading to different costs, and di®erent average execution speeds. The advancement of the task will be stochastic, and the manager may change the allocated amount of resources according to the way the task is progressing. The revenues will depend on the time to the completion of the task, and their expected value will follow a stochastic process. We consider that a strategy for completing the task will consist on a set of rules that de¯ne the level of resources to be chosen at each moment, according to the values of several state variables. We discuss the evaluation for completing the task, and we brie°y address the problem of finding the optimal strategy
- A tool to manage tasks of R&D projectsPublication . Fialho, Joana; Godinho, Pedro; Costa, João PauloWe propose a tool for managing tasks of Research and Development (R&D) projects. We define an R&D project as a network of tasks and we assume that different amounts of resources may be allocated to a task, leading to different costs and different average execution times. The advancement of a task is stochastic, and the management may reallocate resources while the task is being performed,according to its progress. The operational cash flows depend on the task completion time, and their expected values follow a stochastic process. We consider that a strategy for completing a task is a set of rules that define the level of resources to be allocated to the task at each moment. We discuss the evaluation of strategies for completing a task, and we address the problem of finding the optimal strategy
