Optimization of Metal Sheet Cutting Processes Using Integer Linear Programming:...
Pereira, Marisa G.; Pereira, M. Teresa; Fernandes, Miguel A.; Silva, Francisco G.; Guimarães, André; Ferreira, Fernanda A.This paper presents an optimization approach for metal sheet cutting processes using Integer Linear Programming (ILP). It addresses the critical challenges of material waste and inefficiencies inherent in traditional manual cutting methods. The primary objective was to develop and implement an ILP-based model to automate and optimize cutting plans, thereby minimizing material waste and enhancing production effi...
A Hybrid Strategy for Oven Optimization in Aerospace Manufacturing: Lean Princi...
Pereira, M. Teresa; Pereira, Marisa G.; Ferreira, Fernanda A.; Silva, Francisco G.; Guimarães, AndréAdopting the Lean philosophy is essential for reducing costs and increasing productivity in industrial environments, where equipment efficiency plays a pivotal role. This study focuses on optimizing the use of an oven, a critical equipment, in the aircraft parts manufacturing process, in a company producing composite components for aerospace applications. A mathematical model based on the classic two-dimensiona...
Enhancing Third-Party Logistics Efficiency: A Digital Approach to Transport Cos...
Pereira, M. Teresa; Gabriel, Nuno Miguel; Pereira, Marisa G.; Ramos, Filipe R.; Guimarães, AndréOver time, organizations and their supply chains have adapted to constant global change by increasingly adopting digital technologies for optimization, operational efficiency, and competitive advantage. These technologies, which are part of digital transformation, automate manual and repetitive processes, optimize operations and reduce human error. In this project, a decision support model was developed using P...

Proposal of process confirmation methodology through lean principles in logisti...
Silva, Bruna S. Martins da; Pereira, M. Teresa; Ferreira, Fernanda A.; Oliveira, MarisaNowadays, the challenges in this logistics sector influence companies to invest in means and resources to make their logistics processes more efficient, with higher quality and lower cost, without compromising the supply chain processes and business evolution requirements. Therefore, as part of the Process Improvement role carried out in a retail company, the Process Confirmation methodology has been developed ...
Development of a decision support system for freight forecasting
Martins, João P.; Ramos, Filipe R.; Pereira, M. Teresa; Oliveira, Marisa; Ferreira, Fernanda A.The transportation of goods is critical to supply chains, directly influencing efficiency, cost management, and competitiveness. Accurate freight cost forecasting is essential for decision-making, enabling businesses to allocate resources effectively, reduce financial uncertainties, and ensure timely deliveries. This study, conducted in the After-Sales department of a global company, aimed to analyse freight co...

Development of a cost estimation model in a furniture manufacturer
Reis, Francico; Amaral, António; Oliveira, Marisa; Ferreira, Fernanda A.; Pereira, M. TeresaThis work was developed to improve the costing process of new products within the Product Development Department of a furniture manufacturer. It consisted of creating a parametric cost estimation model based on applying simple and multiple linear regressions, considering the existing data of the products produced and their respective costs. The proposed model considers the cost estimation of creating a product ...
Definition of a decision support model for calculating the economic production ...
Pereira, M. Teresa; Magalhães, Hugo; Ferreira, Fernanda A.; Barreiras, AlcindaThis paper proposes a Decision Support System (DSS) for Calculating the Economic Production Lot Size. The focus is on the analysis of improvement of manufacturing productivity in the packaging industry, specifically in a metal packaging company. Through combining different SKUs (Stock Keeping Units) in the same production order, as opposed to the current single SKU orders production paradigm of, it is possible ...
A VRP model to support last mile maritime containers
Pereira, M. Teresa; Ferreirinha, Luís; Ferreira, Fernanda A.; Oliveira, MarisaDue to the constant and hasty development of the process of economic globalization, the transport network has become increasingly complex. This causes significative changes in the manner of cargo transport, which leads to satisfy the costumer’s needs first and only then try to achieve an effective and efficient low-cost distribution. The decision support system developed allows to allocate the closest truck, wi...
