- 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.
- Process Mining in a Line ProductionPublication . Santos, Cristina; Fialho, Joana; Silva, Jorge; Neto, TeresaThe search for more efficient strategies, cost savings, time optimization and productivity are the main goals of any successful company. Process mining arises in this context and, although it is not a new concept, its expansion and applicability in the market has recently become notorious. Through an extensive set of data recorded over time, it is possible to determine the real state of a company's processes, allowing to diagnose failures and improve the efficiency of these processes. This paper describes a project realized in the scope of process mining, developed in the company Huf Portuguesa. The machines of a production line record thousands of data. In a specific production line, data was collected in a time range, cleaned and processed. Process mining techniques allowed the discovery and analysis of the real state of the production line. All paths were detected, and each path was analyzed individually. The conformity was also analyzed.
- 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
