An integrated simulation model for analysing electricity and gas systems
(2014)
This paper aims at analysing the impacts of interdependencies between electricity and natural gas systems in terms of security of energy supply. When analysing both systems several interdependencies can be observed, however, ...
A Self-Adaptive Heuristic Algorithm for Combinatorial Optimization Problems
(2014)
This paper introduces a new self-tuning mechanism to the local search heuristic for solving of combinatorial optimization problems. Parameter tuning of heuristics makes them difficult to apply, as parameter tuning itself ...
WEEE estimation and determination of collection points: A case for the Municipality of Cankaya
(2018)
Electrical-electronic waste (WEEE) is generated from electric and electronic devices at the end of their lifecycles. When WEEEs are disposed, burned or disassembled for recycling, they are transformed into products containing ...
Modified self-adaptive local search algorithm for a biobjective permutation flow shop scheduling problem
(2019)
Interest in multiobjective permutation flow shop scheduling (PFSS) has increased in the last decade to ensure effective resource utilization. This study presents a modified self-adaptive local search (MSALS) algorithm for ...
Performance enhancement of production systems using fuzzy-based availability analysis and simulation method
(2020)
Due to the complexity of today's engineering systems, accurate system performance analysis is important to obtain a more productive system design. This study introduces a new approach to obtain a new system design considering ...
Airfoil-slat arrangement model design for wind turbines in fuzzy environment
(2020)
In this study, a multi-element wind turbine blade that consists of NACA 6411 and NACA 4412 leading-edge slat design is investigated computationally. Optimum design parameters of the slatted wind turbine blade leading to ...
The development of a reviewer selection method: a multi-level hesitant fuzzy VIKOR and TOPSIS approaches
(2021)
This paper proposes a new approach for the selection of reviewers to evaluate research and development (R&D) projects using a new integrated hesitant fuzzy VIKOR and TOPSIS methodology. A reviewer selection model must have ...
A New Multi-Echelon Repair Network Model with Multiple Upstream Locations for Level of Repair Analysis Problem
(2021)
Level of repair analysis (LORA) determines (1) the best decision during a malfunction of each product component; (2) the location in the repair network to perform the decision and (3) the quantity of required resources in ...
Analysis of the manufacturing flexibility parameters with effective performance metrics: a new interactive approach based on modified TOPSIS-Taguchi method
(2022)
Flexibility is one of the most important strategy parameters to achieve a long-term successful performance for a manufacturing company. Studies in the literature aim to operate a manufacturing system at optimum levels of ...
A Multi-Objective Mathematical Model for Level of Repair Analysis with Lead Times and Multi-Transportation Modes
(2022)
In the event of failure of the product, level of repair analysis (LORA) is used to determine (1) whether the defective component should be discarded or repaired and (2) where this repair is made. In the literature, these ...
