Abstract:
A computer-implemented process for determining optimum configuration parameters for a buffered industrial process, comprising the steps of:initializing a population of a predetermined size by randomly selecting a first set of design and operation values associated with subsystems and buffers of the buffered industrial process to form a set of operating parameters for each member of the population; performing an availability discrete event simulation (ADES) on each member of the population to determine a fitness of each member as determined by a product-base availability of each member and selecting a predetermined number of members ranked according to product-based availability to form an initial population; mutating the initial population with a genetic algorithm to produce a mutated population; evaluating the fitness of each member of the mutated population using ADES to determine the product-based availability; forming a new initial population including members having a highest fitness; and iterating subsequent population members determined with the genetic algorithm with product-based availability determined by ADES to form improved design and operation values from which the configuration parameters are selected for the buffered industrial process.
