Dao Minh Hoang, Tran Van Xuan, Tran Ngoc Thang · Annals of Computer Science and Information Systems · 2022
In this paper, we deal with fuzzy random objectives in a multi-criteria crop planning problem considered as a multiobjective linear programming problem.These fuzzy random factors are related to decision making processes in practice, especially the uncertainty and synthesized objectives of experts.The problem is transformed into a multi-objective nonlinear programming problem by a step of evaluating expectation value.Instead of using classical methods, we use a multi-objective evolutionary algorithms called NSGA-II to solve the equivalent problem.This helps finding many approximate solutions concurrently with a low time consumption.In computational experiments, we create a specific fuzzy random crop planning problem with the data synthesized from government's reports and show convergence of the algorithm for proposed model.
