Development of a lean approach in simulation using surface works operations of road construction.

摘要

Lean production theory as a production management tool, describes a system that delivers a finished product that is free from defects, to a customer in zero time, with nothing left in inventory. Lean production theory can be summarized into three main points; (1) Eliminate or reduce all activities that do not add value to the final product, (2) pull material through the process (instant delivery of required materials), and (3) reduce variability by controlling uncertainties within the process.; This thesis presents a universal approach that will facilitate the implementation of the concepts of lean production theory into computer simulation models and in turn actual construction projects. In order to accomplish this a special purpose simulation template was developed for surface works operations in road construction. This template allows for the creation of surface works road construction simulation models that provide industry practitioners a tool for analyzing, optimizing, and improving construction operations. With respect to this thesis, the template provides a means of testing the concepts of lean production on road construction simulation models to quantify their impact on road construction processes. The results obtained from this exercise are used in the development of the generic approach for the application of lean principles in computer models.
