Sergio Scheer

Sergio Scheer is now a Senior Professor at the Universidade Federal do Parana (Federal University of Paraná - UFPR) where he was working from 1981 to 2017 as a Full Professor. He continues to be a research leader at the Civil Engineering Research Center at the same University and is an independent consultant for ICT in AEC. He has a bachelor degree in Civil Engineering from UFPR (1979), a master degree in Structural Engineering from Federal University of Rio Grande do Sul - UFRGS (1982) and a PhD in Computer Science from Catholic University of Rio de Janeiro (Pontifícia Universidade Católica do Rio de Janeiro) - PUC-RJ (1993). He was visiting scholar at CIFE/Stanford University (from oct 2014 to Sept 2015). With more than three hundred papers published, he is a member of ASCE Global Center of Excellence in Computing and ASCE Technical Council on Computing and Information Technology (TCCIT). He is also the 'representative member' of Brazil in the Board of Directors of the International Society for Computing in Civil and Building Engineering (ISCCBE). He acted as a member of the Working Committee for Information Technology (WC 6) of the International Society for Bridges and Structural Engineering (IABSE) from 2001 to 2009. He was the founder and leader of the ICT Task Group of the Brazilian Association for Technology in the Built Environment (GT.TIC/ANTAC) (2012-present) and he was the president of the same association (2018-2022). He is one of the founders of BIM Forum Brasil (July 2020) where now he plays the role of member of the Advisory Board. At the moment he is the Technical Coordinator of the buildingSMART Brasil (since August 2023). Professor Scheer has strong experience in Computer Science and Information Technology for applications in Engineering, focusing on Graphical Processing and Visualization, systems development, and teaching and learning environments. He is acting on the following subjects: Information and Communication Technology (ICT) for Architecture, Engineering and Construction (AEC), specially in BIM and systems integration for AEC, as well as in collaborative work, innovative applications, and educational objects development for engineering education.

The increasing long distances to the construction site, the topography, the occurrence of rain, the often low level of skills among construction workers and a number of other factors affect the level of this uncertainty in Brazil. The challenge ...

Therefore, the algorithm is implemented in order to solve the Resource-Constrained Project Scheduling Problem – RCPSP. The problem modeling is adapted to the type of project in question, where, at first, the activity network of a single housing unit is defined through an activity-on-the-node graph and afterwards the Line of Balance method is used in order to determine the start and finish dates of all the other repetitive activities of the project. In order to test the efficiency of the algorithm, numerous experiments are performed with project instances from the PSPLIB, a specific benchmark database for the RCPSP, available online. Finally, in order to better visualize the schedules obtained in the optimization phase, a 4D simulation of a schedule for the execution of a housing complex, generated with the metaheuristic procedure, is performed with the software Autodesk Navisworks. The simulation phase allows the visualization of the projects constructability, makes it possible to confirm if the algorithm-generated schedule follows a logical sequence, as well as it supports the decision-making about the best execution alternatives.
