- PublicationDerailed locomotive? Petrobras investments and economic growth in Brazil(Universitat Politècnica de València, 2018-01-31) Yabiko, Raíssa Fernandes; Bone, Rosemarie Bröker; Universidade Federal do Rio de Janeiro[EN] Petrobras is the largest firm in Brazil and one of the largest in the world. Its investment plans are among the biggest in the oil and gas industry, focused in Brazil and on E&P. Petrobras is responsible for a large share of gross capital formation and gross domestic product (GDP) growth in the country. The correlation between its investments and the country investment and GDP growth is above 0.8 and shows the dependency of the economy to Petrobras activity. At the same time, as a state enterprise it has been a tool of macroeconomic policy. In the 2010´s its gasoline and diesel prices were frozen to keep inflation down. The recent crisis in the company, including corruption scandals and oil price slump increased debt levels and reduced its capital expenditures. The sale of assets directive since 2016 is required to reduce its net debt. While a medium to long term survival strategy, the change in Petrobras’ investment profile may decrease the prospects of GDP growth in the Brazilian economy.
- PublicationClustering product innovators: a comparison between conventional and green product innovators(Universitat Politècnica de València, 2018-01-31) Pons, Marc; Bikfalvi, Andrea; Llach, Josep[EN] This paper aims at analysing firms implementing new products. Based on a cluster analysis, three types of manufacturers have been identified representing different types of product innovators according to the competitiveness factors important for their business, environmentally sensitive new products, and a performance indicator, such as the share of turnover from new products.
- PublicationA MILP for multi-machine injection moulding sequencing in the scope of C2NET Project(Universitat Politècnica de València, 2018-01-31) Andrés Navarro, Beatriz; Sanchis, Raquel; Poler, Raúl; Díaz-Madroñedo, Manuel; Mula Bru, Josefa; Departamento de Organización de Empresas; Centro de Investigación en Gestión e Ingeniería de Producción; Escuela Politécnica Superior de Alcoy; European Commission[EN] The goal of C2NET European H2020 Funded Project is the creation of cloud-enabled tools for supporting the SMEs supply network optimization of manufacturing and logistic assets based on collaborative demand, production and delivery plans. In the scope of C2NET Project, and particularly in the Optimisation module (C2NET OPT), this paper proposes a novel holistic mixed integer linear programing (MILP) model to optimise the injection sequencing in a multi-machine case. The results of the MILP will support the production planner decision-making process in the calculation of (i) moulds setup in certain machines, and (ii) the amount of products to produce in order to minimise the setup, inventory, and backorders costs. The designed MILP takes part of the algorithms repository created in C2NET European Funded Project to solve realistic industry planning problems. The MILP is verified in realistic data considering three data sets with different sizes, in order to test it’s the computation efficiency.
- PublicationWhat we know and do not know about organizational resilience(Universitat Politècnica de València, 2018-01-31) Ruiz-Martin, Cristina; López-Paredes, Adolfo; Wainer, Gabriel; Universidad de Valladolid; Banco Santander; Natural Sciences and Engineering Research Council of Canada[EN] We present a literature review about organizational resilience, with the goal of identifying how organizational resilience is conceptualized and assessed. The two research questions that drive the review are: (1) how is organizational resilience conceptualized? and (2) how is organizational resilience assessed? We answer the first question by analysing organizational resilience definitions and the attributes or characteristics that contribute to develop resilient organizations. We answer the second question by reviewing articles that focus on tools or methods to measure organizational resilience. Although there are three different ways to define organizational resilience, we found common ideas in the definitions. We also found that organizational resilience is considered a property, ability or capability that can be improved over time. However, we did not find consensus about the elements that contribute to improving the level of organizational resilience and how to assess it. Based on the results of the review, we propose a conceptualization of organizational resilience that integrates the three views found in the literature. We also propose a four-level Maturity Model for Organizational Resilience – MMOR. Using this model, the organization can be in one of the following levels based on its ability and capacity to handle disruptive events: fragile, robust, resilient or antifragile.
- PublicationDesigning an Environmental Zone in a Mediterranean City to Support City Logistics(Universitat Politècnica de València, 2018-01-31) Ros-McDonnell, Lorenzo; de-la-Fuente-Aragon, María Victoria; Ros-McDonnell, Diego; Cardós Carboneras, Manuel[EN] European cities are facing enormous challenges in accessibility and livability terms due to several European directives, which are compulsory in the mid/long term, traffic congestion levels are still increasing, and air pollution and noise disturbs citizens’ lives. This work presents the study carried out in a Mediterranean city to define an Environmental Zone with traffic restrictions for vehicles in the historical centre of the city of Cartagena (Spain) by exploring different urban logistics measures to tackle main problems caused by freight deliveries and pickups in the city centre. These solutions aimed to enhance the efficiency of vehicles, and to reduce both traffic congestion the environmental impacts caused by freight delivery in the city in order to improve urban sustainability.
