The construction site layout (CSL) design presents a particularly interesting area of study because of its relatively high level of attention to usability qualities, in addition to common engineering objectives such as cost and performance. However, it is difficult combinatorial optimization problem for engineers. Swarm intelligence (SI) was very popular and widely used in many complex optimiza...

SightPlan is an expert system that performs construction site layout. The system contains an explicit representation of the strategy it follows to construct a solution. Based on the assumption that the cognitive capabilities of an agent have an impact on the strategy that agent follows during problem-solving, we decided to experiment with alternate strategies. We modeled one strategy after the ...

Selecting construction methods, scheduling activities, and planning the use of site space are key to constructing a project efficiently. Site layout and activity scheduling have been tackled as independent problems. Their interdependence is often ignored at the planning stage and may be dealt with—if at all—when construction is underway. Problems that may have had easy solutions if dealt with e...

Based on the current situation of temporary pipelines with disorderly layout and low integration, roads time consuming, material consuming environmentally unfriendly in, construction site, a new type reusable assembly power pipe trench road system technology is proposed in this paper. The research background ideas are described; partition, structure connection designed; stress checked by finite...

The present research is intended to address dynamic construction-process simulation methods, with a focus on how to effectively model resource transit among various activity locations in the site system. Following a review of basic simulation paradigms and recent research developments, we propose a new process mapping and simulation methodology for modeling construction operations. The simulati...

Meta-heuristic algorithms proved to find optimal solutions for combinatorial problems in many domains. Nevertheless, the efficiency of these algorithms highly depends on their parameter settings. In fact, finding appropriate settings of the algorithm’s parameters is considered to be a nontrivial task and is usually set manually to values that are known to give reasonable performance. In this pa...

Preliminary layout design of buildings has a substantial effect on the ultimate design of structural components and accordingly influences the construction cost. Exploring structurally efficient forms and shapes during the conceptual design stage of a project can also facilitate the optimum integrated design of buildings. This paper presents an automated method of determining column layout desi...

The NavChair Assistive Navigation System (Levine, Koren, & Borenstein 1990) is being developed to increase the mobility of severely handicapped individuals by providing navigation assistance for a power wheelchair. While designing the NavChair it became clear that obtaining the full range of desired functionality required several different “operating modes,” each of which was appropriate in dif...
