In this paper, we study different methods of solving joint redundancy-availability optimization for series-parallel systems with multi-state components. We analyzed various effective factors on system availability in order to determine the optimum number and version of components in each sub-system and consider the effects of improving failure rates of each component in each sub-system and impr...

pumps are among the early instruments invented by humans to be taken advantage of in the use of water utilities. design and operation problem of pumping stations is a type of mixed integer non linear programming, in which gradient based optimization methods are not efficient for solving complex problems of this type. in this regard, such evolutionary optimization algorithms as genetic algorithm...

In today’s global economy, process plants are under constant pressure to reduce costs. Users can no longer afford their attempts to make pumps bulletproof by upgrading component specifications. The development of a smart pumping system was fostered by a challenge from a major chemical user to reduce the total cost of pump ownership. A smart pumping system was successfully developed that can rea...
