Towards sustainable smart cities: Integration of home energy management system ...
Ghanavati, Farideh; Matias, João C. O.; Osório, Gerardo J.Smart Homes (SHs) play a crucial role in the broader context of smart cities, contributing to the overall efficiency, sustainability, and quality of life for residents. This work presents a computationally efficient mathematical model for Home Energy Management Systems (HEMS) to activate the Demand Side Management (DSM) while minimizing the energy consumption costs of SHs. The proposed model is represented as a...
Optimal self-scheduling of home appliances and electrical vehicles with Home En...
Ghanavati, Farideh; Matias, João C. O.; Osório, Gerardo J.This work investigates the self-scheduling of home appliances and provides a timeline for optimal charging of Electric Vehicles (EVs) at home. The model utilizes a computer-based self-scheduling algorithm to minimize the cost of electricity while the preferences of the end-users have been considered in the model. Different electricity tariffs have been simulated in this study to assess the electricity costs of ...

Applying the SMED Methodology to Tire Calibration Procedures
Santos, Vítor; Sousa, Vitor F. C.; Silva, Francisco J. G.; Matias, João C. O.; Costa, Rúben D.; Pinto, Arnaldo; Campilho, RaulDue to the automotive industry’s strict demands, customers submit constant production pressure, leading to the adoption of new methodologies, techniques, and management ideas. The goal is always to minimise losses and waste. These demands also affect the maintenance department, which has to keep the balance between machines’ availability for production and ensuring that the machines’ proper running conditions t...
Support of advanced technologies in supply chain processes and sustainability i...
Azevedo, Susana Garrido; Pimentel, Carina Maria Oliveira; Alves, Anabela Carvalho; Matias, João C. O.This paper aims to present a study of the type of advanced technologies used across manufacturing supply chains in supporting the main processes of the supply chain operations reference model (SCOR). It also intends to identify a set of sustainable performance indicators (environmental, economic, and social) suitable to evaluate a supply chain 4.0 (SC4.0). To attain this objective, based on the literature revie...
