Incremental Construction for Scalable Component-Based Systems

Abstract

The availability of smart and intelligent sensors has changed the monitoring, control and maintenance of a conventional and advanced cyber-physical system used in public or private sectors of a society. For example, internet of things (IoT)-based health, agricultural and weather management systems. With the emergence of such sensors, along with the new ways to communicate or coordinate with them, we need to analyze and optimize the system construction processes. In this paper, to address the issue of scalability for bigger and complex systems based on sensors, we redefine an incremental construction process with an emphasis on behavior preservation and study the effectiveness of the use of software component models from the component-based development domain. In this paper, to deal with the issue of scalability, we investigate component-based development approaches with respect to our defined process and propose a taxonomy of component models with respect to component/system behavior. Moreover, based on the outcome of our analysis, we recommend the EX-MAN component model as the most suitable approach. We investigate incremental construction in the context of the three main categories of current component models, namely models where components are: (i) objects, (ii) architectural units and (iii) encapsulated components. Furthermore, to evaluate our defined process and selection of EX-MAN, we designed three examples of systems using our proposed process in EX-MAN component model.

Sensing technologies in construction engineering education: industry experiences and expectations

“…Sensing technologies are technologies that extract information about the context and condition of construction resources and processes during the lifecycle of facilities to improve communication between project participants, enhance project safety and improve quality control (Akinci and Anumba 2008). Sensing technologies are broadly classified as image-based (Teizer 2008, Teizer 2015 and component-based technologies (Akanmu, Anumba et al 2020, Rana andBaz 2020). Image-based sensors include laser scanners and cameras, while component-based sensors include radio frequency identification tags, global positioning tags, accelerometers, and temperature and humidity sensors.…”

A Generalised Coordination Design Pattern for the EX-MAN Component Model

“…In order to validate the methodology, we have implemented the exogenous connector of EX-MAN in a prototype tool exogenous composition framework (ECF). These connectors are used in building many component based systems [39], [41] and the overall behaviour of connectors in the system is checked and simulated. To model and simulate EX-MAN systems with the defined exogenous connectors, we have developed a prototype tool (Figure 28(a)) ECF.…”

A Component Model with Verifiable Composition for the Construction of Emergency Management Systems

“…EX-MAN proposes a number of new features to address the limitations of X-MAN. The selected component model uses independent components to be composed by predefined connectors for system construction [43]. EX-MAN is a general purpose component model.…”
