A constructive aisle design model for unit-load warehouses with multiple pickup and deposit points
(ELSEVIER, 2014)We develop a network-based warehouse model of individual pallet locations and their interactions with appropriate cross aisles in order to evaluate the expected travel distance of a given design. The model is constructive ... -
A disassembly line balancing problem with fixed number of workstations
(ELSEVIER, 2016)In this study, a Disassembly Line Balancing Problem with a fixed number of workstations is considered. The product to be disassembled comprises various components, which are referred to as its parts. There is a specified ... -
A Novel Arc-routing Problem of Electric Powered Street Sweepers with Time Windows and Intermediate Stops
(ELSEVIER, 2019)Waste collection is an important public service performed by municipalities. Powered street sweeping is an important part of waste collection. Recently, electric powered street sweepers are used at an increasing rate for ... -
A predictive control strategy for optimal management of peak load, thermal comfort, energy storage and renewables in multi-zone buildings
(ELSEVIER, 2019)Buildings are responsible for about 40% of the global energy consumption, where heating, ventilation and air conditioning (HVAC) systems account for the most part of it. Continuous increase in the installation of new HVAC ... -
A simulation-based experimental design for SBS/RS warehouse design by considering energy related performance metrics
(ELSEVIER, 2020)This paper deals with an experimental study for shuttle-based storage and retrieval system (SBS/RS) design to identify significant factors affecting the performance metrics in the system. SBS/RS is an automated warehouse ... -
Alpha momentum and alpha reversal in country and industry equity indexes
(ELSEVIER, 2019)Do past alphas predict future country and industry returns? Examination of equity indexes from 51 stock markets between 1973 and 2018 allows us to demonstrate new return patterns in the cross-section of country and industry ... -
An analysis of Emergency Medical Services demand: Time of day, day of the week, and location in the city
(ELSEVIER, 2017)Objective: Effective planning of Emergency Medical Services (EMS), which is highly dependent on the analysis of past data trends, is important in reducing response time. Thus, we aimed to analyze demand for these services ... -
An ensemble genetic programming approach to develop incipient sediment motion models in rectangular channels
(ELSEVIER, 2020)Assimilating unique features of genetic programming (GP) and gene expression programming (GEP), this study introduces a hybrid algorithm which results in promising incipient non-cohesive sediment motion models. The new ... -
Applying Mathematica and webMathematica to graph coloring
(ELSEVIER, 2007)This paper analyzes some graph issues by using the symbolic program Mathematica and its version for the Web, webMathematica. In particular, we consider the problem of graph coloring: the assignment of colors to the ... -
Behavioral factors on the adoption of sustainable supply chain practices
(ELSEVIER, 2020)Sustainable supply chain management (SSCM) has become a popular research topic among scholars as evidence suggests it has significantly contributed to achieve more environmentally conscious and socially responsible supply ... -
Comparative assessment of time series and artificial intelligence models to estimate monthly streamflow: A local and external data analysis approach
(ELSEVIER, 2019)River flow rates are important for water resources projects. Given this, the current study explored the use of autoregressive (AR) and moving average (MA) techniques as individual time series models and compared them to ... -
Decay factor optimisation in time weighted simulation - Evaluating VaR performance
(ELSEVIER, 2011)We propose an optimisation approach for determining the optimal decay factor in time weighted (BRW) simulation. The backtesting of the BRW simulation, which involves different decay factors, together with a broad range of ... -
Developing novel hybrid models for estimation of daily soil temperature at various depths
(ELSEVIER, 2020)Estimation of soil temperature (ST) as one of the vital parameters of soil, which has an impact on many chemical and physical characteristics of soil, is of great importance in soil science. This study applies a time ... -
Differential evolution algorithm with ensemble of parameters and mutation strategies
(ELSEVIER, 2011)Differential evolution (DE) has attracted much attention recently as an effective approach for solving numerical optimization problems. However, the performance of DE is sensitive to the choice of the mutation strategy and ... -
Drought modeling using classic time series and hybrid wavelet-gene expression programming models
(ELSEVIER, 2020)The standardized precipitation evapotranspiration index (SPEI) at three different time scales (i.e., SPEI-3, SPEI-6, and SPEI-12) from six meteorology stations located in Turkey are modeled in this study. To this end, two ... -
Ensemble of metaheuristics for energy-efficient hybrid flowshops: Makespan versus total energy consumption
(ELSEVIER, 2020)Due to its practical relevance, the hybrid flowshop scheduling problem (HFSP) has been widely studied in the literature with the objectives related to production efficiency. However, studies regarding energy consumption ... -
Hybrid models to improve the monthly river flow prediction: Integrating artificial intelligence and non-linear time series models
(ELSEVIER, 2019)Prediction of river flow as a fundamental source of hydrological information plays a crucial role in various fields of water projects. In this study, at first, the capabilities of two time series analysis approaches, namely ... -
Methodological approach for performance assessment of historical buildings based on seismic, energy and cost performance: A Mediterranean case
(ELSEVIER, 2020)Historic buildings need to be re-functionalized because of environmental factors, economic reasons, sociocultural changes. During the re-functionalization-renovation period, only the seismic performance of the building is ... -
Multi-Period Vehicle Routing & Replenishment Problem of Neighbourhood Disaster Stations for Pre-Disaster Humanitarian Relief Logistics
(ELSEVIER, 2019)Natural disasters are uncontrollable situations that affect human life directly. Despite the researches and technological progress, it is still not possible to predict when or where the natural disaster will occur beforehand. ... -
Performance analysis of a solar-hydrogen driven multigeneration system
(ELSEVIER, 2020)Environmental concerns have gained great attention in the last decades, especially the global warming caused by usage of fossil fuels mostly. Renewable energy sources are the most reasonable way to decreasing the fossil ...
