Like many existing ERP models (e.g., Podolsky, 1998; Van Stijn & Wensley, 2001), the OOAB framework is also based on a widely accepted assumption that a corporate-wide information system consists of a set of potentially related subsystems; and as a result, information flows among these subsystems must be identified, and required resources planned, using an appropriate ERP methodology. However, up until now there existed no formalised framework that facilitates sharing of contextual knowledge in ERP processes. A unique attribute of the OOAB framework is that it treats ERP processes as a collaborative processes where various roles/actors collaboratively perform tasks in order to achieve a common overall goal. An object-oriented framework is presented in this article that facilitates sharing the contextual knowledge/resources that exist within ERP processes. Context is represented by a set of relevant collaborative semantic concepts or “objects”. These are the objects that are localised/contextualised to specific sub-process within the ERP process.

Continuous authentication was introduced to propose novel mechanisms to validate users’ identity and address the problems and limitations exposed by traditional techniques. However, this methodology poses several challenges that remain unsolved. In this paper, we present a novel framework, PALOT, that leverages IoT to provide context-aware, continuous and non-intrusive authentication and authorization services. To this end, we propose a formal information system model based on ontologies, representing the main source of knowledge of our framework. Furthermore, to recognize users’ behavioral patterns within the IoT ecosystem, we introduced a new module called “confidence manager”. The module is then integrated into an extended version of our early framework architecture, IoTCAF, which is consequently adapted to include the above-mentioned component. Exhaustive experiments demonstrated the efficacy, feasibility and scalability of the proposed solution.

This paper provides a design of the Information System architecture to support a connected construction site. In order to master the diversity and the complexity of construction site processes, theories are needed that separate the stable essence of the smart construction site from the variable way in which it is realized and implemented. For that, construction site processes were mapped before linking each data path with the existing technological tools using correspondence matrixes. The results enable the definition of a proper system able to deal with the resources allocated to the construction process functionalities. The main challenge faced in this research was to identify which pertinent data is needed that activates the resources to complete each given construction task.

Construction Safety Management

Abstract Safety management is very important for construction sector as it is the most hazardous working environments when it comes to occupational fatalities. The high cases such as injuries at the workplace, illnesses, and fatalities often caused harm to the workers and create the delay on the work progress. Therefore, this paper reviewed the whole operation process of the sensor modules that enhanced safety performance to prevent accidents occurred on construction site. By providing lab scale location-based safety management services to the workers, this technology able to allow a speedy response in the event of accident. From the benchmark conducted, there are three study that had been conducted previously using vibrational alert signal which identified as an accurate transmitted especially inside a danger zone, as the vibrational function of the sensor module able to function within the designated range. The second benchmark shows that previous study able to identify errors in the location information of the workers arising from obstacles, even though so the technology able to conveyed within the designated range as well. Thirdly, the previous study able to shows the information of a fall was conveyed quickly upon occurrence, and the previous study showed that fall able to identified using the context-aware information from the sensor module. The findings showed that the real-time location and context-aware information collected from the sensor module can be used to prevent accidents and respond quickly in the event of a fall. However, the vibration signal which generated by sensor module was insufficient to alert the workers when approaching the danger zone at construction site. Therefore to improve the whole development of prototype sensor module a further study is needed to incorporate the vibrational and alarm signal for recognising accidents upon occurred for enhancement safety management at construction sites.
