A Lean-Based System for Decision-Making in Construction Projects Integrating BIM and Operations Simulation

Summary

The complexity of decision-making during the execution of construction projects has been the driving force for several research initiatives over the last decade to propose decision-making support systems for construction projects. Building Information Modelling (BIM) has been proven effective to support construction decision-making by providing a centralised platform that facilitates capturing and retrieving project information at a high level of accuracy, especially when coupled with the recent advancements in data capturing techniques. In addition, Operational Research (OR) digital techniques, such as digital twin simulation and optimisation, have been recently utilised to develop live virtual models that are capable of testing decision scenarios on construction projects’ objectives before execution. On the other hand, several approaches have been proposed to promote lean principles in construction decision-making, such as the Last Planner System and Target Value Design.

This project is to explore the interface between BIM, OR, and Lean Construction to develop a decision-making support system that enables project managers to evaluate their decisions based on accurate project data utilising the analytical capabilities of OR techniques while maintaining lean practices to minimise waste and improve productivity. Other aspects of integration will be investigated including tackling industry barriers to using digital technology in decision-making and the technical requirements to implement the proposed system.

Applicants to research degree programmes should normally have at least a first class or an upper second class British Bachelors Honours degree (or equivalent) in an appropriate discipline. The criteria for entry for some research degrees may be higher, for example, several faculties, also require a Masters degree. Applicants are advised to check with the relevant School prior to making an application. Applicants who are uncertain about the requirements for a particular research degree are advised to contact the School or Graduate School prior to making an application.

The minimum English language entry requirement for research postgraduate research study is an IELTS of 6.0 overall with at least 5.5 in each component (reading, writing, listening and speaking) or equivalent. The test must be dated within two years of the start date of the course in order to be valid. Some schools and faculties have a higher requirement.
