Many applications and industrial processes require very low cooling temperature, such as cold storage in the biomedical
field, requiring temperature below -80 °C. However, single-cycle refrigeration systems can only achieve the effective
cooling temperature of -40 °C and, also, the performance of the cycle will decrease drastically for cooling temperatures
lower than -35°C....

ABSTRACT
This study considers the real situations of production between the products and the setup of production tools that are different. Therefore, this study considers the setup time of work stations and production batch in the production scheduling. This study proposed a random optimization algorithm with multi objective that can be...

In an industrial set-up, conditions of orthogonality and optimality of a statistical experimental design often get violated. This paper attempts to find an optimal design which performs uniformly better with respect to multi-design-optimality criteria. Initially, using non-dominated
sorting genetic algorithm (NSGA-II) with single D-optimality criterion, a near-optimal design is searched for...
