- Sectorization of a Parcel Delivery ServicePublication . Mostardinha, Mafalda; Escobar Hernández, Pablo; Lopes, Isabel Cristina; Rodrigues, Ana MariaThis paper explores the problem of sectorization of a parcel delivery service that wants to assign an action region to each of its teams, regarding the number of deliveries scheduled for each zone, so that there is a balanced service amongst sectors, covering contiguous zones, and considering limited capacities for the teams. Besides being relatively easy to model, the available optimization tools and software provide poor results when dimension increases in these types of problems, with computational capacity exceeding. In this paper an integer programming model, combined with an heuristic to return a faster solution, was implemented to solve a sectorization problem in two different situations. The main advantage of the strategy proposed, compared to previous ones, is its simplicity and easy implementation while still returning an optimal solution.
- Introducing a Postgraduate Phase of Qualification at Universities of Applied Sciences: Collaboration and Quality in Doctoral EducationPublication . Gille, Michael; Krappe, Johanna; Morgado, Celda; Pausits, Prof. Dr. Habil. Attila; Mostardinha, MafaldaSeveral EU Member States are implementing policies to develop the role of universities of applied sciences (UAS) in the training of early-stage researchers. The application-oriented research at UAS frequently draws on collaboration, not only between researchers with different disciplinary backgrounds but also with a wide range of regional, national, and international partners. Doctoral education takes place in this practice-oriented environment and often extends into multiple third mission areas. Doctoral education at UAS can be broadly divided into two policy approaches: First, UASs have a formal role in early-stage researchers’ development including co-supervision with a degree-awarding university. Second, UASs become entitled to award doctorates independently. We aim to obtain a European perspective on the quality assurance discussion associated with this newfound role of UASs. To examine how the policies in the four selected member states are put into practice, we address the following questions: What role is ascribed to UASs by the policymakers and what conceptualizations of the UASs ́ `applied´ doctorate emerge? How do the requirements of collaboration fit into this? A thematically focussed case analysis of four member states’ models (Austria, Finland, Germany, Portugal) aims to elucidate the underlying notions of the policymakers. The discussion of foundational conceptualizations outlines possible fields of investigation for a reflection on these developments against the backdrop of the European Higher Education Area.
