Multiobjective Pareto optimal solutions for epoxy semi-batch polymerization process are obtained by adapting nondominated sorting genetic algorithm II (NSGA II). The objective is to produce polymer of maximum possible number average molecular weight (Mn) with a specified value of polydispersity index (PDI) and number average molecular weight in minimum possible time. The M and reaction time a p...

To assemble a heavy payload to the spacecraft (free-floating base), present study proposes scheme of multiobjective trajectory planning for preimpact motion redundant space manipulator (mounted on base). Force impulse self-assembly is derived as function joint angles/velocities, base pose, and impact direction. The problem formulated optimization minimize force impulse, attitude disturbance, en...

Abstract The design of geosynthetic-reinforced and pile-supported (GRPS) embankments is traditionally optimized by searching for the most cost-effective solution among several workable candidates. candidates are usually based on experiences engineers, real optimal could be therefore missed. This paper intends to address above-mentioned issue systematically optimizing GRPS considering simultaneo...

Decision making with multiple criteria requires preferences elicited from the decision maker to determine a solution set. Models of preferences, that follow upon the concept of nondominated solutions introduced by Yu (1974), are presented and compared within a unified framework of cones. Polyhedral and nonpolyhedral, convex and nonconvex, translated, and variable cones are used to model differe...

In this paper some concept of fuzzy set have discussed and one fuzzy model have applied on agricultural farm for optimal allocation of different crops by considering maximization of net benefit, production and utilization of labour . Crisp values of the objective functions obtained from selected nondominated solutions are converted into triangular fuzzy numbers and ranking of those fuzzy number...
