Planning for construction projects faces challenges due to complexity in design and short deadlines. Further, very limited tools are available to planners for integrating the visual representations of site with the progress of time, which results into their relying on experience and imagination to decide the appropriate sequence of construction plan. In the study, the 4D Model has been develope...

In CAD, symbolic geometric solvers allow to solve constraint systems, given under the form of a sketch and a set of constraints, by computing a symbolic construction plan describing how to build the required figure. But a construction plan does not usually define a unique figure, and the selection of the expected figure remains an important topic. This paper expose three methods, automatic or i...

1. introduction any development with any quantity or quality degree has particular environmental impacts. human manipulation in natural environment does not necessarily mean making changes in initial environment. continuity of human action in the changing natural conditions, which could eventually disrupt the balance of existing environment or causes unintended and unforeseen consequences as cu...

introduction international commission on radiological protection (icrp) has provided a comprehensive discussion on threshold dose for radiation-induced cataract in icrp publication 116. accordingly, various parts of the eye lens have different radio-sensitivities. recently, some studies have been performed to develop a realistic eye model with the aim of providing accurate estimation of fluence...

In an airline company, one of the most important tasks is to control the operational plan, i.e., making sure that flights are executed according to the scheduled plan. When the normal functioning is affected by an unexpected event, disruption management appears in order to solve all possible issues. From aircraft to passenger, operation control centers have to effectively fix all the disrupted ...

Earthwork projects involve moving specific amounts of earth from a discrete set of source locations to a discrete set of destinations. Constructors use different methods and equipment to move earth depending primarily on haul distance and equipment availability. Successful earthwork projects involve successively refined cycles of construction plan preparation and evaluation. The construction pl...
