In modern machine tool design, precision is an important index to characterize performance and allocation has become a key task. Since the middle of twentieth century, methods using optimization technology balance manufacturing cost level have gradually developed, but most mainly take minimization as goal optimize allocation. As costs are pair factors be comprehensively considered, between them...

Generally, off-line methods are used for surface roughness prediction of titanium alloy milling. However, studies show that these have poor accuracy. In order to resolve this shortcoming, a method based on Cloudera’s Distribution including Apache Hadoop (CDH) platform is proposed in the present study. regard, data analysis and process designed CDH, which can upload, calculate, store real time. ...

 In this research, a tri-objective mathematical model is proposed for the Transportation-Location-Routing problem. The model considers a three-echelon supply chain and aims to minimize total costs, maximize the minimum reliability of the traveled routes and establish a well-balanced set of routes. In order to solve the proposed model, four metaheuristic algorithms, including Multi-Objective Gre...

The optimal performance of a wireless mesh network (WMN) can be greatly improved by strategically placing routers. As result, it is crucial to optimally locate the WMN routers for better coverage and connectivity. Besides placement, congestion due overlaying has taken into consideration. These issues have become motivation researchers identify variety approaches optimize performance. Multiple m...

Cars are regarded as an indispensable means of transportation in Taiwan. Several studies have indicated that the automotive industry has witnessed remarkable advances and market used cars rapidly expanded. In this study, a price prediction system for BMW was developed. Nine parameters cars, including their model, registration year, transmission style, were analyzed. The data obtained then divid...

For remote places having less-strong wind, single resources based renewable energy system (RES) with battery storage can sustainably and economically generate electrical energy. There is hardly any literature on optimal sizing of such RES for very low load demand situation. The objective of this study is to techno-economically optimize the system design of a Photovoltaic (PV)-battery storage RE...

Due to frequent drought events, increased water demand for agricultural production and limited, accurate estimation of reference evapotranspiration (ETo) is necessary developing crop irrigation schemes rational allocation regional resources. The extreme learning machine (ELM) was optimized using four biological heuristic algorithms, namely, Grey Wolf Optimizer (GWO-ELM), Moth-Flame Optimization...
