This paper describes the application of Kriging metamodeling in multiple-objective simulation optimization. An Arenabased simulation model of an (s, S) inventory system is utilized to demonstrate the capabilities of Kriging metamodeling as a simulation tool. Response surface methodology and Kriging metamodeling are compared to determine the situations in which one approach might be preferred ov...

Havacılık endüstrisinde uçak komponentlerinin Bakım (Maintenance), Onarım (Repair) ve Revizyon (Overhaul) (MRO) hizmetleri önemli bir süreç olmakla birlikte maliyetlerin büyük kısmını oluşturmaktadır. Bir uçağın ortalama 25-30 yıldan fazla ömre sahip dayanıklı yapıda olduğu gerçeği ilerleyen yıllarda ağır bakım gelirlerinin yerini komponent hizmetlerinin alacağı öngörüsü ile bu pastadan pay ala...

in this study, modeling and optimization of coagulation and flocculation processes in cod removal of galvanized wastewater treatment plant of mobarakeh steel complex (msc) were studied. experiments of this study were designed using response surface method which is one of the most efficient methods in experimental design. the variables assessed in this study, are four factors including ph, input...

Handling conflicting objectives and finding multiple Pareto optimal solutions are two challenging issues in solving multiobjective optimization problems (MOPs). Inspired by the efficiency of multitask (MTO) problem (MTOP), we propose to treat MOP as a MTOP solve it using MTO. By transforming into MTOP, not only that difficulty handling can be avoided, but also MTO help efficiently find well-dis...

Having consistent diagnosis in Process Automation brings to customers great potential saving in the maintenance, repair and operations (MRO) phase. The German-based process industry end-user association NAMUR has published a recommendation, NE 107 (“Self-Monitoring and Diagnosis of Field Devices”). To follow these requirements, investigations and perspective on EtherNet/IP will be needed. This ...

An optimization procedure was applied to investigate the anticandidal property of four different Iranian seaweed extract compositions. Response Surface Methodology (RSM) with the four levels- three–factor Box–Behnken design, including Gracilaria arquata concentration (X1), Nizimudidnia zanardini concentration (X2), Cystoceria indica concentration (X3) and Padina australis concentration (X4), wa...

Ensuring reliable and stable communication during the movements of mobile users is one key issues in networks. In recent years, several studies have been conducted to address related Handover (HO) self-optimization Heterogeneous Networks (HetNets) for Fourth Generation (4G) Fifth (5G) Various solutions developed determine or estimating optimum ideal settings Control Parameters (HCPs), such as T...
