Frequently Asked Questions
Q1 : Why do we optimise in process design?
A1 : Among others, optimization of process design are needed to: 1. Minimise total cost of a design 2. Optimise operation (planning and scheduling) 3. Minimise capital expenditure 4. Minimise operating cost 5. Maximise profit 6. Improve plant performance (yield, selectivity, use of resources, etc.) 7. Improve environmental performance
Q2 : What is objective function?
A2 : Objective function is performance index that is expressed in terms of design variables. It is the goal of optimisation is to find the values of the variables that yield the optimal value of the objective function.
Q3 : What are the importance of design variable(s) in optimization?
A3 : In optimization, design variable is always involved with a trade-off. Changing the value of a variable may bring benefits in one part of the design but has detrimental effects in other parts. There must be an optimum value for the design variable(s) in achieving the objective functions.
