- Framework for a risk assessment model to apply in Virtual / Collaborative EnterprisesPublication . Ávila, Paulo; Mota, Alzira; Bastos, João; Patrício, Leonel; Pires, António; Castro, Helio; Cruz-Cunha, Maria Manuela; Varela, LeonildeRisk assessment is a theme of large spectrum applied in different fields. In the context of Virtual / Collaborative Enterprises there are several risks whose assessment should be aware to avoid undesirable consequences either for entire networked or for a partner in particular. The objective of this work is centered on the creation of a framework / guidelines to serve as a basis for the creation of a better risk assessment model for Virtual / Collaborative Enterprises. This work analyzed the few models available in the literature and identified some gaps that were used to purpose complementary guidelines for the design and / or improve the future risk assessment models. The pointed guidelines covered three important topics: risk factors; assessment methods; and the impact in different life cycle phases of a Virtual / Collaborative Enterprise. Considering the results of the work it is our conviction that there is space to improve the research in this field and a more robust and flexible risk assessment model should be developed.
- Adaptations of a resources system selection problem of Distributed/Agile/Virtual Enterprises for using genetic algorithmsPublication . Ávila, Paulo; Mota, Alzira; Putnik, Goran; Costa, LinoThe selection of resource systems is still a difficult matter to solve in distributed / Agile / Virtual enterprises ( D/A/V Es ) integration. Attempts to solve the resources selection problem, has originated several models and consequently different algorithms have been applied to obtain solutions. The exact algorithms have good performance (in terms of computational time) for low dimension problems. However, become ineffective as the complexity increases. Genetic algorithms are considered robust and versatile. These have been applied to complex problems in several application areas and gained popularity in innumerable research works. To improve the computational time in solving the resources selection problem, we pretend to apply a genetic algorithm. Due to the characteristics of the model, the application of this algorithm forced adjustments in the initial model. In this work, we present the adaptations performed in the study model in order to use genetic algorithms.
- An algorithm of a costing system for electroplatingPublication . Pires, António; Ferreira, Fábio; Ávila, Paulo; Mota, AlziraBusinesses are increasingly competitive and rigorous and it is essential the existence of a strong, effective and realistic costing system. Decisions taken on the basis of the costing are very important, they can make the difference between success and failure of the organization. This paper explains the construction of an initial algorithm that aims to calculate the costs associated with electroplating of metal articles, in a specific company. This work can act as a possible guide for the construction of the costing system algorithms in this type of industry.
- Collaborative Planning in Non-Hierarchical Networks—An Intelligent Negotiation-Based FrameworkPublication . Bastos, João; Azevedo, Américo; Ávila, Paulo; Mota, Alzira; Costa, Lino; Castro, HelioIn today’s competing business market, companies are constantly challenged to dynamically adapt to customer expectations by diminishing the time response that goes from the beginning of the business opportunity to the satisfaction of the customer need. Simultaneously, there is increased recognition of the advantages that companies obtain in focusing on their core business and seeking other competencies through partnerships with other partners by forming collaborative networks. These new collaborative organizational structures require a new set of methods and tools to support the management of manufacturing processes across the entire supply chain. The present paper addresses the collaborative production planning problem in networks of non-hierarchical, decentralized, and independent companies. By proposing a collaborative planning intelligent framework composed of a web-based set of methods, tools, and technologies, the present study intends to provide network stakeholders with the necessary means to responsively and efficiently address each one of the market business opportunities. Through this new holistic framework, the managers of the networked companies can address the challenges posed during collaborative network formation and supply chain production planning.
- Analysis of methods for supplier selectionPublication . Mendes, Luís; Ávila, Paulo; Bastos, João; Mota, AlziraThis work seeks to determine the criteria and methods used in the problem of selecting suppliers, thus contributing to the support of entities wishing to start a selection of suppliers more effectively. To achieve these objectives, an analysis was performed of articles that make the literature review of the methods and criteria from the year 1985 to the year 2012. With the data obtained from these reviews, it was possible to verify which are the three main methods used over the years, namely data envelopment analysis (DEA), Analytical hierarchy process (AHP) and Fuzzy set theory and the main criteria used in the selection of suppliers. In this work, we present an overview of the decision making and the methods used in multi-criteria decision making. It’s tackled the problem of supplier selection, the process of selection and the reviews of literary methods and criteria used in recent years. Finally is presented the contribution to the selection of suppliers of the study conducted during the development of this dissertation, being presented and explained the main methods of selection of suppliers as well as the criteria used.
- Livro de resumos do 9º Encontro Nacional de Engenharia e Gestão IndustrialPublication . Ávila, Paulo; Lopes, Manuel; Pinto Ferreira, Luís; Pereira, Teresa; Mota, Alzira; Rocha, Pedro; Azevedo, JulianaA 9ª edição do Encontro Nacional de Engenharia e Gestão Industrial foi realizada no Instituto Superior de Engenharia do Porto (ENEGI 2022). Este encontro foi coorganizado pelos alunos de Engenharia e Gestão Industrial e docentes dos cursos de Licenciatura e Mestrado de Engenharia e Gestão Industrial do Instituto Superior de Engenharia do Porto. Cientificamente foi apoiado pelos diretores de curso das licenciaturas, mestrados e programas doutorais, na área da Engenharia e Gestão Industrial, lecionados em Portugal. Este encontro visou dar resposta à vontade de partilha de conhecimento entre estudantes, docentes, investigadores e quadros de empresas de todo o país, que anualmente se reúnem para debater as diferentes áreas da Engenharia e Gestão industrial. O evento compreendeu da apresentação de trabalhos realizados por alunos dos cursos de Engenharia e Gestão Industrial, apresentação de empresas, sessões plenárias e debates em mesa-redonda. A comissão organizadora agradece a todos os conferencistas, aos moderadores das sessões, aos oradores principais, à comissão científica que procedeu à revisão dos resumos das comunicações, às empresas participantes, e ao suporte institucional da Presidência do Instituto Superior de Engenharia do Porto.
