Software

Several programming packages have been designed and implemented during the graduate study by Mr. Dai to help address civil and construction engineering problems. The applications include finite element analysis, structural calculations, critical path method based scheduling, AutoCAD ObjectARX redevelopment, web-based information management system.

Description: Simulation-based scheduling tool for construction operations planning, analysis, and optimization, being able to address the problem of total float calculation residing in MS Project and P3 under constraints of multiple calendars.

Development Platform: Visual C++

Underlying Technologies: Critical Path Method, Discrete Event Simulation, and Evolutionary Optimization

CPM (critical path method) system flow

Schedule optimization – resource allocation

2. HKCONSIM-RealTime

Description: Real-time decision-support tool for concrete plant delivery in Hong Kong, powered by in-vehicle positioning & navigation, mobile data communication, simulation, and optimization technologies.

Development Platform: Delphi

Underlying Technologies: Discrete Event Simulation and Evolutionary Optimization
