The research presented applies the PROMODEL alongside a simplified discrete-event simulation approach (SDESA) and its software platform resulting from in-house construction research for modeling typical construction operations. The characteristics and modeling needs for construction and manufacturing systems are compared in general. A simple earth-moving operation and a real site operation inte...

Automated construction technologies have been developed and introduced in the Japanese construction industries since the 1980s. However, the construction industry remains a craftoriented and labor-intensive industry with minimal automation of tasks. Automation of construction processes has potential significant effects on construction of buildings. This paper describes the history of research a...

Despite of the advances in construction planning and scheduling software, construction managers and planners are still facing problems in achieving accurate planning, scheduling and costing due to the one-off nature of the construction projects and the inherently uncertain site conditions and soil characteristics. The aim of the research presented in this paper is to introduce a new methodology...

geographic information systems (gis) are one of the fastest growing computer-based technologies of past two decades, yet, full potential of this technology in construction has not been realized. based upon gis capabilities, construction site layout is one of the areas that gis could be applied. the layout of temporary facilities (tfs) such as warehouses, fabrication shops, maintenance shops, co...

The contemporary environmental issues are alleviating through green supply chain management (GSCM) practices in the construction industry; bring economic benefit and sustainability for the business organization. Construction industry operations are very complex and integrated supply chain i.e. GSCM practice is the best way to reduce construction waste and improving environmental performance. Th...

This paper is in two parts: in part one, our main object is to give a construction of natural λ-operations for relative K-theory with supports, satisfying the special λ-ring identities. In the second part, we give an application to the relation of motivic cohomology and algebraic K-theory of a smooth quasi-projective variety over a field. The main idea in the construction of the λ-operations is...

We propose an algebraic approach to block diagram construction as an alternative to the classical graph approach inspired by dataflow models. The proposed algebra is based on three binary operations of construction : sequential, parallel and recursive constructions. These operations can be seen as high level connection schemes that set several connections at once in order to combine two block d...

The use of an unmanned aerial system (UAS) in construction project management (CPM) is emerging methodology aimed at improving the performance practices. Despite different functions that UAS offers, which are well covered various sources ranging from isolated exploratory works to ad hoc case studies, practitioners still demonstrate little interest technology. underwhelming rooted a lack underst...
