Man-made disaster prevention using waste management hierarchy and disaster management cycle

The amount of construction waste generated is enormous due to the growth of the construction activities, which might lead to serious environmental problems. This is also including the construction waste that was generated from the natural disaster. This potential human-made disaster has been receiving worldwide attention and becomes a significant concern across nations. Thus, many studies on the effectiveness of construction waste management practices have been done. However, statistics do not show any improvement in the number of construction waste production. This paper aims to investigate the state of the art of construction waste management practice in Malaysia and the human-made disaster management strategies that feasible to be applied. Data were collected using the semi-structured interview with the key informants of the construction professional service providers in Malaysia and analyzed through thematic content analysis. An in-depth conceptualization and a new theoretical insight are developed on the strategy to prevent this human-made disaster caused by the construction waste. Findings from the cross-sectional content analysis and cognitive mapping propose a new human-made disaster management strategy in the construction caused by the construction waste that suits to Malaysian context

Architecting systems-of-systems and their constituents : A case study applying Industry 4.0 in the construction domain

The development of system-of-systems (SoS) requires a continuous interplay between design decisions on the SoS level and those on the level of its constituent systems (CS), which often preexist and need to be adapted as the SoS evolves. This involves not only preparing the CS to participate in a particular SoS, but also designing the CS architecture to make it easily adaptable to a future SoS context. The problem is in part addressed in an emerging SoS framework in the manufacturing domain called Industry 4.0. It focuses on connected and digitalized production with the ambition of increasing flexibility and efficiency. This paper investigates how Industry 4.0 standards can be used in an SoS context to make CS more flexible and adaptive, and evaluates their usefulness outside manufacturing. The study is based on a case from the construction domain, for which a generic SoS architecture is developed. Several extensions and adaptations of Industry 4.0 are suggested, including specifications of ontologies for missions and workflows. © 2019 The Authors. Funding details: 2018-03244, 2018-00671; Funding text 1: informationThis research was funded by the Swedish Governmental Agency for Innovation Systems (Vinnova), Formas and Sweden's Energy Agency, within their joint program InfraSweden2030 under grant no. 2018-00671, and by Vinnova under grant no.?2018-03244.</p
