Construction has always been characterized as a fragmented, complex, and challenging industry. This has been reflected throughout the life cycle of construction projects, whether in design, construction, or operation and maintenance (O&M). Although efforts have been made to identify and solve problems in design and construction, there is a high degree of disconnection and lack of consensus in the O&M stage, represented by Facility Management (FM). This paper carries out a bibliographic review of the challenges and problems faced by facility management and the methods and technologies proposed for their solution. Moreover, an introduction to Virtual Design and Construction is made as an emerging methodology showing interesting results in the design and construction stages. The hypothesis is that the same positive results can be obtained if VDC were applied to an O&M stage. Finally, an Int...

The implementation of any software development process involves the consumption of critical resources. Software engineers cannot experiment with different development processes before starting them in real projects, due to the time that would entail and the amount of elements that are involved, so it is vital to have tools that allow the pre-visualization of the results of executing the software development process and how the environmental variables affect it, thus being able to anticipate under what conditions the software development process will be deployed. This paper presents the modelling and simulation of a software development process using System Dynamics (SD), which allows the graphical representation of the elements intervening in the software process, and the incorporation of as many relevant elements as possible. As a software costs estimation reference, the COCOMO estimati...
