| Summary: | Most construction projects involve use of construction machines, construction plant manager has to consider both timeliness and flexibility to develop an efficient schedule of dispatching construction machines, which can balance the operations at different construction sites. In this paper, we constructed an optimization model with multi-target as construction quality, time limit, efficiency and cost. The model consists of a database, a rule- based system and multi-target decision making modules. The database includes detailed data about construction machine types and their properties. The rule-based system module provides rules, which are utilized by inference engine for determining the most proper construction machine type. Ultimately, a final decision is made for the most proper construction machine among the alternatives of the same type using the information axiom of axiomatic design principles. In order to verify the validity of the model, evaluation of alternatives is made for the cases of both complete and incomplete information.
