Resistance reactions of onion landraces collected from Turkey to the stem and bulb nematode Ditylenchus dipsaci
(Akdeniz Üniversitesi, 2020)
A total of 27 accessions of different onion landraces from Turkey were screened for their resistance to stem and bulb nematode. The study was carried out in a growth chamber at 20°C, with a 16/8 h (light/dark) photoperiod ...
Evaluating of hospital appointment systems in Turkey: Challenges and opportunities
(Elsevier, 2021)
Background: Recently, appointment registration systems (especially phone and web-based) that provide easier access to hospital medical services have become more common than traditional queuing registration systems. Therefore, ...

Use of the heuristic optimization in the parameter estimation of generalized gamma distribution: comparison of GA, DE, PSO and SA methods
(Springer, 2020)
The generalized gamma distribution (GGD) is a popular distribution because it is extremely flexible. Due to the density function structure of GGD, estimating the parameters of the GGD family by statistical point estimation ...
Structural and operational management of Turkish airports: a bootstrap data envelopment analysis of efficiency
(Elsevier, 2021)
This paper explores the structural and operational dimensions of the efficiencies of airports. The two-stage procedure is suggested to assess the efficiencies of airports in this study. In the first-stage, Classification ...
A simplistic approach without epsilon to choose the most efficient unit in data envelopment analysis
(Pergamon-Elsevier Science, 2021)
Data envelopment analysis is a very effective mathematical instrument in assessing the performance of decision making units. In most real cases, the decision-maker need to identify a single most efficient unit. Several ...
The determination of the most suitable inertia weight strategy for particle swarm optimization via the minimax mixed-integer linear programming model
(Emerald Publishing, 2021)
Purpose
This paper aims to consider each strategy of the particle swarm optimization (PSO) as a unit in data envelopment analysis (DEA) and uses the minimax mixed-integer linear programming DEA approach to find the most ...
A minimax approach for selecting the overall and stage-level most efficient unit in two stage production processes
(Springer, 2021)
Data envelopment analysis (DEA) is a very effective management tool in assessing the performance of a set of decision making units (DMUs). In the efficiency evaluation using classic single stage DEA models, the internal ...
Performance management of OECD countries on Covid-19 pandemic: a criticism using data envelopment analysis models
(Emerald Group Holdings Ltd., 2021)
The Covid-19 pandemic spread rapidly around the world and required strict restriction plans and policies. In most countries around the world, the outbreak of the disease has been serious and has greatly affected the health ...
Hierarchical groups DEA cross-efficiency and TOPSIS technique: An application on mobile money agents locations
(Inderscience Publishers, 2022)
Ranking of efficient decision-making units (DMUs) allows a further analysis of the data envelopment analysis (DEA) efficient DMUs, where otherwise a high number of efficient DMUs can be identified. The current research ...
