Project description

Canada is facing a major crisis as many of the main infrastructure systems are reaching their end of serviceable life. Major investments in the coming years will be required to renew and upgrade critical infrastructure assets such as storm and waste water systems, transportation systems and power generation, transmission and distribution facilities. Technological advances over the past few decades have resulted in increasing complexity of these integrated civil infrastructure systems. As a result of this, the management and maintenance of these systems is becoming increasingly challenging as the systems age. System performance and reliability is a result of the interdependencies between engineered, natural and human system components. Traditional engineering risk analysis tends to focus on extreme events which have a low probability and thus contribute very little to the overall system reliability. There is a widely recognized need to move toward integrated systems modelling to gain a better understanding of system response to a variety of loads, demands and operational decisions that occur both within and outside of the design envelope. This research aims to develop an advanced risk analysis methodology for implementation with civil engineering infrastructure systems and test the utility of the developed methodology by applying it to a set of real BC Hydro systems of hydropower flow-control. Interactions between natural, engineered and human system components will be considered under the entire range of operating conditions for a variety of system configurations. The goal of this research is to develop a systems approach to risk assessment as it relates to day to day system operation. The proposed simulation tool could be used in planning of budgets, staffing requirements, maintenance, capital upgrades, day to day operations, and also for the training of new employees. It has the potential to play a critical role in whole-life cycle asset management and help asset owners determine a long term strategy for the renewal of aging infrastructure.
