Integration planning of freight deliveries into passenger bus networks: exact a...
Machado, Bruno; Pimentel, Carina; Sousa, Amaro deWith the increasing population living in cities, a growing number of small daily urban freight deliveries are performed, typically by private companies. Recently, more environmentally friendly urban logistics services have emerged to mitigate the negative effects of such activities. One example is the integration of freight deliveries into bus networks, traditionally dedicated to passenger transportation, to pe...
PDCA Protocol to ensure a Data-Driven Approach for Problem-Solving
Brochado, Ângela; Rocha, Eugénio; Pimentel, CarinaProblem-solving based, as much as possible, on real data, expert knowledge, and on-field observation are quite desired objectives. However, it creates several difficulties on deployment in real situations. In this work, a data-driven version of the well-known PDCA cycle is proposed for continuous improvement within a general class of problems represented by key performance indicators (KPI). Such class is wide e...
Understanding and predicting process performance variations of a balanced manuf...
Brochado, Ângela F.; Rocha, Eugénio M.; Pimentel, CarinaIndustry 4.0 takes advantage of data-driven approaches to improve manufacturing processes. Root cause analysis (RCA) techniques are naturally required to support the identification of reasons for (in)efficiency processes. However, RCA methods tend to be sensitive to data perturbations and outliers, compromising the confidence of the results and demanding the implementation of robust RCA approaches. Here, method...
Occupational health and safety in construction projects: a case study on chemic...
Costa, Olga; Matias, João; Pimentel, CarinaBackground: This study was conducted to demonstrate the importance of occupational health and safety (OHS) management in construction project environments, taking into account the successful development of those projects. The associated problems in OHS management projects were also studied, as substantial empirical research has shown this is a complex theme with a large number of associated factors. Methods: In...

Integrated urban freight logistics combining passenger and freight flows - Math...
Pimentel, Carina; Alvelos, Filipe Pereira eThe aim of this research is to propose an urban logistics distribution service which benefits from the already installed passenger transport network. This service is based upon the concept of integration of the existing passenger transport network with the urban freight process. The aim is to reduce the number of fossil combustion powered commercial vehicles traveling within city boundaries, solely for goods tr...

This method resorts to different tools, in order to seek operators commitment to maintain optimal condit...
IEM graduates transition to the labour market: the importance of internships
Amorim, Marlene; Pimentel, Carina; Rosa, Maria JoãoThis paper addresses the role of internships for the transition of IEM graduates to the labour market. We conducted an exploratory study with former graduates from the University of Aveiro, Portugal, in order to develop our understanding about the role of internships for: i) the consolidation of knowledge acquired by students in IEM academic subjects; ii) the development of other competences which are not preva...
Exact and heuristic approaches for lot splitting and scheduling on identical pa...
Pimentel, Carina; Alvelos, Filipe; Duarte, António; Carvalho, J.M. Valério deIn this paper, we address a lot splitting and scheduling problem existent in a textile factory. The factory we study produces a set of products that are made of, or assembled from, a list of components. During production, each component can be split into one or several lots of different sizes and each lot will be produced independently on one of a group of identical parallel machines. We formulate the problem i...
