  • Abstract:
    This paper discusses an approach that was developed to enable effective use of systems simulation in the scheduling of construction projects. The approach was implemented in a software program named SimCon, which enhances current simulation methods through the use of continuous production links for activities that comprise a project. The continuous production links provide construction managers with a flexible representation of activity sequencing. The procedure builds on existing CYCLONE fundamentals through new constructs to connect processes in a simulation-based project plan. These constructs are used to simplify the cyclic interprocess relationships, standardize the techniques for logical linking of simulation processes, provide a better estimate of progress, and model a continuous and smooth flow of construction. Various scheduling alternatives are modeled without the need to change activity sequencing, as is required in current scheduling systems. Examples from an actual construction project show the advantages of the continuous production links. The concepts are implemented using a prototype computer system that integrates object-oriented concepts, event-driven programming, a relational database, and a simulation system.
