**Risk response strategies**

In order to cope with the inherent risk in projects, risk response strategies should be properly defined, analysed and implemented. Risk response strategies consist of risk prevention (to reduce the probability of risk occurrence) and rist protection (to reduce the impact of risk). On this page, you find a summary of our research on risk response strategies in project management.

Implementing a proper risk response strategy requires the optimal allocation of limited budgets to either prevention and protection, taking into account the parameters of the risk model. OR&S has investigated this **budget allocation problem for risk response strategies **from different angles.

**1. An analytical model**

In order to analyse the impact of linear and non-linear cost/risk relations on the optimal budget, an analytical analysis is presented to provide guidelines to project managers.

**2. A fault tree optimisation**

Risk events are triggered by causes and lead to consequences, which can be modelled in a fault tree risk analysis network. An optimisation model to solve the budget allocation model with 4 types of risk models is presented and managerial insights are provided.

**3. A branch-and-bound optimisation**

In the fault tree optimisation paper, we proposed the development of a branch-and-bound procedure as future research. One day, we will work on this.

**4. A genetic algorithm**

In the fault tree optimisation paper, we proposed the development of meta-heuristic procedures as future research. One day, we will work on this.
