Building makeshift hospitals is one of the important measures to deal with COVID-19 outbreak, which has brought great pressure and challenges China's public health system. Makeshift hospital construction usually uses prefabricated boxes, provide faster construction, safer manufacturing, better quality control lower environmental pollution compared traditional on-site construction. In process pr...

Current construction worksite layout planning heavily relies on 2D paper media where the worksite planners sketch the future layout adjacent to their real environment. This traditional approach turns out to be ineffective and prone to error because only experienced and well-trained planners are able to generate the effective layout design with paper sketch. Augmented Reality (AR), as a new user...

Construction projects consist of multiple components such as on-site equipment resources, site layout, labor productivity, unexpected external events, and human decisions regarding resource allocation and activity rescheduling. Stochastic spatial and temporal interactions between those components result in dynamic complexity of construction projects. Decisions made in such dynamic task environm...

rough sets theory is a mathematical approach for analysis of a vague description of objects presented by a well-known mathematician, pawlak (1982, 1991). this paper explores the use of rough sets theory in site location investigation of buried concrete water reservoirs. making an appropriate decision in site location can always avoid unnecessary expensive costs which is very important in constr...

This paper introduces a novel approach to enhance the general practice of layout planning of construction sites for producing the efficient utilization. In this work, a solution to the problem is attempted for unequal and irregular temporary facility using robust search and optimization capabilities of Ant Colony Optimization (ACO) algorithm, inspired by the foraging behaviour of real ants. The...

The drawing of Venn diagrams have traditionally served as an aid to analyze the characteristics exhibited by the diagram and its underlying Venn graph. Little attention has hitherto been given to the presentation, construction and way in which a Venn diagram conveys information. We present a new algorithm for the construction and layout of a Venn diagram based on an incremental technique. The a...

We address graph visualization from the viewpoint of com piler construction Most data structures in compilers are large dense graphs such as annotated control ow graph syntax trees dependency graphs Our main focus is the animation and interactive exploration of these graphs Fast layout heuristics and powerful browsing methods are needed We give a survey of layout heuristics for general directed...

With this PCell wrapper, MGEN layout generators appear like usual SKILL based PCells within DF II. A wrapper PCell must be created for each layout generator. The wrapper PCells just differ in the parameters declarations and the corresponding construction of the layout generator command line. The MGEN environment creates the wrapper PCells automatically. mgenlayoutcds mostran model=nreg w=1u l=1...
