PSO is used to solve the reformulated problem and priority ranking of constraint fitness is proposed to guarantee that the constraints are satisfied.
For the HPC example, a user may alter the priority of the cost constraint or turnaround-time constraint.
This paper presents a technique of multi-objective optimization for Model Predictive Control (MPC) where the optimization has three levels of the objective function, in order of priority: handling constraints, maximizing economics, and maintaining control.
In the financial services domain, market conditions may alter the priority of an application's constraints: for example, after a major incident, such as Japan's tsunami or a major downgrade of US credit ratings, the financial analyst may need to perform computation-intensive analysis rapidly.
The outcome of requirements prioritization is a total ordering of requirements that best accommodates the various kinds of constraints and priorities.
It was decided to conduct two Delphi rounds, in anticipation of competing priorities and time constraints of relevant stakeholders in the field of patient engagement [ 21].
Overall, the descriptive evidence suggests that following the crisis, the reform response was characterised by two distinct phases reflecting the evolution of priorities and constraints.
And if that's the case, then Sanders has clearly not done the hard work of figuring out priorities, of operating within constraints, of balancing trade-offs," he writes.
To address this issue, an algorithm is proposed in [115] that divides the constraints into hard and soft constraints according to the priority of objectives.
In the optimization process, a non-dominated sorting algorithm is introduced to judge the priority of each sample and handle the constraints.
