In a just-in-time (JIT) system, kanban number and size represent the inventory level of work-in-process (WIP) or purchasing parts. It is an important issue to determine the feasible kanban number and size. In this research, an integrated multiple-objective genetic algorithm (MOGA) based system is developed to determine the Pareto-optimal kanban number and size, and is applied in a JIT-oriented ...

Power system security enhancement is a major concern in the operation of power system. In this paper, the task of security enhancement is formulated as a multi-objective optimization problem with minimization of fuel cost and minimization of FACTS device investment cost as objectives. Generator active power, generator bus voltage magnitude and the reactance of Thyristor Controlled Series Capaci...

A multi-item multiperiod inventory control model is developed for known-deterministic variable demands under limited available budget. Assuming the order quantity is more than the shortage quantity in each period, the shortage in combination of backorder and lost sale is considered. The orders are placed in batch sizes and the decision variables are assumed integer. Moreover, all unit discounts...

MOTIVATION With an increase in the number of known biological functions of non-coding RNAs, the importance of RNA sequence alignment has risen. RNA sequence alignment problem has been investigated by many researchers as a mono-objective optimization problem where contributions from sequence similarity and secondary structure are taken into account through a single objective function. Since ther...

We report the identification of a number of mutations that result in amino acid replacements (and their phenotypic characterization) in either the MogA-like domain or domains 2 and 3 of the MoeA-like region of the Aspergillus nidulans cnxE gene. These domains are functionally required since mutations that result in amino acid substitutions in any one domain lead to the loss or to a substantial ...

In this study, the effect of adding hydrogen to natural gas and EGR ratio was conducted on a diesel engine investigate performance exhaust gases by AVL Fire multi-domain simulation software. For investigation, mixture fuel replaced fuel. The percentage in blend changed from 0% 40%. compression converted 17:1 15:1. ratios were three steps 5%, 10%, 15%, with different speeds 1000 1800 RPM. Gaussi...

Building energy optimization (BEO) is a promising technique to achieve efficient designs. The efficacy of algorithms imperative for the BEO and significantly dependent on algorithm hyperparameters. Currently, studies focusing hyperparameters are scarce, common agreement how set their values, especially problems, still lacking. This study proposes metamodel-based methodology hyperparameter appli...
