The CHEMCAD Scientific Cluster Initiative (CSCI) addresses a fundamental question:

How solve large scale optimization problems?

A large flowsheet typically contains a combination of the applications mentioned in the table. CHEMCAD solves this optimization task and delivers a converged solution which is a local optimum.

But the problem of finding a global optimum is much more difficult.

Metaheuristics are strategies that guide the search process.

By searching over a large set of converged solutions, metaheuristics can often find good solutions with less computational effort than brute force. Metaheuristics sample a set of solutions which is too large to be completely sampled. Metaheuristic algorithms are approximate and usually non-deterministic.

CHEMCAD SCIENTIFIC CLUSTER INITIATIVE (CSCI) is a toolbox

1. CHEMCAD: An improved Sequential Modular based process simulator

  • easy addition and deletion of modules to and from a flowsheet
  • modules are easier to program and debug than sets of equations
  • modules are easy to construct and understand, and can be re-used

2. Infrastructure for CHEMCAD parallelization

3. Use of metaheuristics

  • Genetic Algorithm is implemented ("Caller")
  • You can connect your own metaheuristic to the infrastructure

4. Tools

  • Process Optimization, i.e. Multivariate Sensitivity Study, Optimum Test, Pareto Front Visualization
  • Management of optimization jobs in the "Lab" cockpit
  • Coordination ("Dispatcher") of parallel CHEMCAD instances ("Agents")

Applications of CHEMCAD SCIENTIFIC CLUSTER INITIATIVE (CSCI)

1. Run multivariate sensitivity studies

2. Run global sensitivity studies

3. Run multi-objective optimizations

4. Run Monte Carlo methods

5. Run stochastic global optimization algorithms
