Variability in Residential Construction

Faculty Advisor:  Dr. Howard Bashford

 

 

Abstract: 

            The goal of this project is to model the process of building a home as a factory manufacturing process.  Industrial Engineers study many ways to shorten and optimize manufacturing processes.  Once home building can be viewed as a manufacturing process, there will be a plethora of techniques available to shorten the time taken to build a house, and optimize many aspects of the building process.  There are, however, a few crucial steps that must come before we are able to set up this model.  We need to find parallel parameters and variables between manufacturing and building, and this is our main mission.  Our primary focus will be on variability:  we need to find out how to quantify it, but before that, we need to figure out what it means in terms of building.  Little’s Law is a relationship between throughput, cycle time, and work in progress.  There are worst case and best case values for these variables that are determined by the variability.  In order to implement Little’s Law, variability must be understood.
