One of the key components of chemical plant operability is flexibility the ability to operate over a range of conditions while satisfying performance specifications. A general framework for analyzing flexibility in chemical process design is presented in this paper. A quantitative index is proposed which measures the size of the parameter space over which feasible steady-state operation of the ...

The inherent complexity of large ships makes it challenging to evaluate ship designs systematically and scientifically. Knowledge-based expert systems can be reasonable solutions. However, this problem needs more rationality better operability, especially in complicated ship-equipment suitability evaluation problems with numerous indicators complex structures. This paper presents a hybrid multi...

This paper presents a proposal for increased emphasis on operability in the Chemical Engineering capstone design courses. Operability becomes a natural aspect of the process design course for a project that is properly defined with various scenarios and uncertainty. Key topics in operability are the operating window, flexibility, reliability, safety, efficiency, operation during transitions, dy...

Many ship accidents are experienced by small boats. With a large number of fishing boats in Indonesia, the risk potential is high. Therefore, an operability analysis must be conducted for various loading conditions to address any safety issues due severe vessel motion. The net cargo boat will change during its operation at sea and then affect vessel’s seakeeping characteristics. This study aims...
