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.
1. S3 (Simplified Simulation-based Scheduling)
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
Visual on-line concrete delivery monitoring and conducting
Real-time order updating and optimization
3. Pisces
Description: Web-based bridge drawing managerial system for bridge structural engineers to reuse the standard and existing shop drawings, so as to improve their design efficiency based on an established drawings reuse mechanism.
Development Platform: Visual C#
Underlying Technologies: Object Oriented Design and Analysis, Relational Database, and Information Management System
Drawing managerial interface of the system
Interface of on-line drawing browse and navigation
