Essential Features of Optimisation Problems

Essential Features of Optimisation Problems Every optimisation problem will have  

At least one Objective Function to be optimised (e.g. profit function, cost function, etc.) often called the economic model 

One or more Inequality Constraints (e.g. lower and uppers bounds of operating variables, such as temperature in a reactor, reflux ratio in a distillation column) 

A set of variables that satisfy the items 2 and 3 precisely will provide feasible solution of the optimisation problem.
