Maria Antónia Carravilla @ FEUP

Maria Antónia Carravilla is a teacher at Faculdade de Engenharia da Universidade do Porto (FEUP) since 1985, visiting professor at Universidade de São Paulo (USP), teacher at Porto Business School in the Executive and Magellan MBA's, and a researcher at INESC-TEC since 1990.

Maria Antónia is the Director of the Doctoral Program in Engineering and Industrial Management (PRODEGI @ FEUP) since 2016.

Maria Antónia Carravilla has been responsible for several R&D contracts with industry, services and public administration. These contracts resulted in reports and decision support systems that proved to be very useful tools for these organizations, leading to long-lasting collaborations with FEUP. The pure research contracts were mainly founded by FCT and are mainly related with the application of constraint programming to the resolution of nesting problems. The R&D contracts and the research contracts were the basis for the theses of several PhD students.

Maria Antónia Carravilla has been a member of the Executive Committee of FEUP for 9 years as Pro-Dean for management and control. She was the Director of the Financial Services and head of the Management Office of FEUP for 7 years. She has been responsible for the Jupiter Project that managed the move of FEUP to the new premises in 2000. She has also been responsible for the projects that resulted in the implementation in FEUP of workflows related with the Financial Services. Within the management office of FEUP she led studies related with indicators for higher education institutions and supervised a masters thesis on sustainability indicators for higher education institutions.

As a teacher at FEUP, Maria Antónia Carravilla has been responsible for several courses related with Operations Research, Operations Management and Logistics that were taught at the BSc, MSc and PhD levels. She has supervised MSc students whose theses were developed in academia as well as in industry.

Maria Antónia Carravilla received in 2009, the first time it has been awarded, FEUP’s Award for Pedagogical Excellence that aims to award the best teacher of FEUP for the past 5 years.

Merging make-to-stock/make-to-order decisions into sales and operations planning: A multi-objective approach

Abstract
With the advent of mass customization and product proliferation, the appearance of hybrid Make-toStock(MTS)/Make-to-Order(MTO) policies arise as a strategy to cope with high product variety maintaining satisfactory lead times. In companies operating under this reality, Sales and Operations Planning (S&OP) practices must be adapted accordingly during the coordinated planning of procurement, production, logistics, and sales activities. This paper proposes a novel S&OP decision-making framework for a flow shop/batch company that produces standard products under an MTS strategy and customized products under an MTO strategy. First, a multi-objective mixed-integer programming model is formulated to characterize the problem. Then, a matrix containing the different strategies a firm in this context may adopt is proposed. This rationale provides a business-oriented approach towards the analysis of different plans and helps to frame the different Pareto-optimal solutions given the priority on MTS or MTO segments and the management positioning regarding cost minimization or service level orientation. The research is based on a real case faced by an electric cable manufacturer. The computational experiments demonstrate the applicability of the proposed methodology. Our approach brings a practical, supply chain-oriented, and mid-term perspective on the study of operations planning policies in MTS/MTO contexts.

A C++ application programming interface for co-evolutionary biased random-key genetic algorithms for solution and scenario generation

Abstract
This paper presents a C++ application programming interface for a co-evolutionary algorithm for solution and scenario generation in stochastic problems. Based on a two-space biased random-key genetic algorithm, it involves two types of populations that are mutually impacted by the fitness calculations. In the solution population, high-quality solutions evolve, representing first-stage decisions evaluated by their performance in the face of the scenario population. The scenario population ultimately generates a diverse set of scenarios regarding their impact on the solutions. This application allows the straightforward implementation of this algorithm, where the user needs only to define the problem-dependent decoding procedure and may adjust the risk profile of the decision-maker. This paper presents the co-evolutionary algorithm and structures the interface. We also present some experiments that validate the impact of relevant features of the application. © 2021 Informa UK Limited, trading as Taylor & Francis Group.
