Balancing of mixed-model parallel U-shaped assembly lines considering model sequences
Küçükkoc, İbrahim; Zhang, David Z. (Taylor & Francis Ltd, 2017)As a consequence of increasing interests in customised products, mixed-model lines have become the most significant components of today's manufacturing systems to meet surging consumer demand. Also, U-shaped assembly lines ... -
Balancing of mixed-model two-sided assembly lines with underground workstations: A mathematical model and ant colony optimization algorithm
Küçükkoç, İbrahim; Li, Zixiang; Karaoğlan, Aslan Deniz; Zhang, David Z. (Elsevier Science, 2018)Mixed-model assembly lines allow the production of different product variants in mass quantities on the same assembly line. In studies addressing mixed-model assembly with two-sided lines, assembly line (work)stations are ... -
Balancing of parallel u-shaped assembly lines
Küçükkoç, İbrahim; Zhang, David Z. (Pergamon-Elsevier Science Ltd, 2015)A new hybrid assembly line design, called parallel U-shaped assembly line system, is introduced and characterised along with numerical examples for the first time. Different from existing studies on U-shaped lines, we ... -
Coping with model variations on parallel u-shaped assembly line configurations
Küçükkoç, İbrahim; Zhang, David Z. (Elsevier Science Bv, 2015)U-shaped assembly lines have always been shown as the intelligent way of producing homogeneous products in large quantities. However; dynamism in product demands and growing interest in customized products force companies ... -
A mathematical model and artificial bee colony algorithm for the lexicographic bottleneck mixed-model assembly line balancing problem
Küçükkoç, İbrahim; Büyüközkan, Kadir; Satoğlu, Şule Itır; Zhang, David Z. (Springer, 2019)Typically, the total number of required workstations are minimised for a given cycle time (this problem is referred to as type-1), or cycle time is minimised for a given number of workstations (this problem is referred to ... -

A mathematical model and genetic algorithm-based approach for parallel two-sided assembly line balancing problem
Küçükkoç, İbrahim; Zhang, David Z. (Taylor & Francis Ltd, 2015)Assembly lines are usually constructed as the last stage of the entire production system and efficiency of an assembly line is one of the most important factors which affect the performance of a complex production system. ... -
Mixed-model parallel two-sided assembly line balancing problem: A flexible agent-based ant colony optimization approach
Küçükkoç, İbrahim; Zhang, David Z. (Pergamon-Elsevier Science Ltd, 2016)Assembly lines are frequently used as a production method to assemble complex products. Two-sided assembly lines are utilized to assemble large-sized products (e.g., cars, buses, trucks). Locating two lines in parallel ... -
Optimising the process parameters of selective laser melting for the fabrication of ti6al4v alloy
Li, Zhonghua; Küçükkoç, İbrahim; Zhang, David Z.; Liu, Fei (Emerald Group Publishing Ltd, 2018)Purpose - Surface roughness is an important evaluation index for industrial components, and it strongly depends on the processing parameters for selective laser molten Ti6Al4V parts. This paper aims to obtain an optimum ... -
Production planning in additive manufacturing and 3D printing
Li, Qiang; Küçükkoç, İbrahim; Zhang, David Z. (Elsevier Ltd, 2017)Additive manufacturing is a new and emerging technology and has been shown to be the future of manufacturing systems. Because of the high purchasing and processing costs of additive manufacturing machines, the planning and ... -
Simultaneous balancing and sequencing of mixed-model parallel two-sided assembly lines
Küçükkoç, İbrahim; Zhang, David Z. (Taylor & Francis Ltd, 2014)Growing interests from customers in customised products and increasing competitions among peers necessitate companies to configure their manufacturing systems more effectively than ever before. We propose a new assembly ... -
Type-e parallel two-sided assembly line balancing problem: mathematical model and ant colony optimisation based approach with optimised parameters
Küçükkoç, İbrahim; Zhang, David Z. (Pergamon-Elsevier Science Ltd, 2015)There are many factors which affect the performance of a complex production system. Efficiency of an assembly line is one of the most important of these factors since assembly lines are generally constructed as the last ...
