In this work, thermal-fluid analysis and optimization of plastic injection molding of the fuse/relay frame of the motor housing of the Peugeot 206 car have been performed using Moldflow software. Also, the development of multiple decision-making methods and decision support systems to Moldflow software in this work have provided tools for analysis and optimization under conditions of uncertainty of this quality. In order to manufacture parts in a mold with good quality, a cooling system must always be designed to transfer heat evenly to the mold and cool the melt with quality. For this optimization of the system, a cooling temperature range corresponding to the melting temperature has been used. The results of this work show that, given that for a cooling temperature of 150°C, the amount of indentation is reduced by at least 49% and the volume shrinkage is reduced by at least 2% compared to other temperatures, and the distortion is also increased slightly, water vapor at a temperature of 150°C will provide the best cooling for the production of the present part. The optimized cooling systems is also achieved as the designed system (1) with 7 cooling fluid inlets and 7 cooling fluid outlets and 15 baffles, the designed system (2) with a channel with a greater distance from the melt and 6 baffles, and the designed system (3) with an increased channel length and 15 baffles. Comparison between the performance of these systems shows that the second cooling system is introduced as the selected cooling system
