This paper discusses Simphony as an integrated environment for building special purpose simulation tools for modeling construction systems. Simphony provides various services that enable the developer to easily control different behaviors in the developed tool such as simulation behaviors, graphical representation, statistics, and animation. These services(More)
The nature of the construction industry combined with the lack of appropriate techniques and technologies suitable for construction work are among the main reasons for inadequate industry performance. Researchers need to develop a better understanding of the construction industry and develop approaches and technologies that will enable construction(More)
Large, complex construction projects, such as industrial plant construction, are not well suited to discrete-event process interaction simulation. The authors present a distributed simulation of industrial plant construction using separate modules inter-linked via the High Level Architecture (HLA). This enables the capture of all features, resources, and(More)
Simulation techniques can provide a resource-driven schedule and answer many hypothetical scenarios before project execution to improve on conventional project management software applications for large-scale construction projects. However, the current process of simulation and optimization of resource utilization is a time consuming process especially for(More)
Simulation built on assumption and approximation has been traditionally utilized to make predictions prior to construction. Although there are many benefits of simulation such as its capability of multiple experiments with various scenario assumptions, it may lead to erroneous predictions when simulation input data are not accurate. Long-term repetitive(More)
Historically, simulation tools have only been used and understood by the academic community. Special Purpose Simulation (SPS) techniques have introduced computer modeling to the industry, resulting in reduced model development time and a user-friendly environment. This paper describes the special purpose simulation template, which is based on the tower(More)
In cold regions, weather severity has a major impact on construction activities carried out in the open, leading to significant deviations from baseline schedules. Faced with weather uncertainty, setting up the project baseline schedule, against which performance will be measured, can be challenging. Construction planners often depend on their personal(More)
We present the development of a bidding game application designed to improve the decision making skills of students in estimating classes by allowing them to compete both against each other and against a virtual player developed using fuzzy logic concepts. The High Level Architecture (HLA) was used to develop a distributed model of the bidding process using(More)
