Productivity improvement through a sequencing generalised assignment in an assembly line system

Consideration of workers’ differences in production systems modelling and design: State of the art and directions for future research

“…ISO 9001 (2015) defined competence as the ability to apply one's knowledge and skills to achieve one's intended results. This definition Gong et al (2018); Moussavi, Mahdjoub, and Grunder (2018); Zhang, Tang, and Zhang (2018); Moussavi, Mahdjoub, and Grunder (2017); Oksuz, Buyukozkan, and Satoglu (2017); Rabbani, Akbari, and Dolatkhah (2017);Fattahi, Samoei, and Zandieh (2016); Li, Huang, and Niu (2016); Samouei et al (2016);Folgado, Pecas, and Henriques (2015); Ramezanian and Ezzatpanah (2015); Sotskov et al (2015); Öksüz and Satoğlu (2014); Denkena, Charlin, and Merwart (2013); Mutlu, Polat, and Supciller (2013); Zhang, Xu, and Gen (2013); Chen et al (2012); Cheng and Chu (2012); Zhang and Gen (2011); Thongsanit, Boondisakulchok, and Tharmmaphornphilas (2010); Süer and Tummaluri (2008); Weng and Onari (2008); Iima, Karuno, and Kise (2005); Gallwey (1992)…”

“…Furthermore, Iima, Karuno, and Kise (2005) assumed that the operation time depends on the assigned worker's skill level. Öksüz and Satoğlu (2014), Samouei et al (2016), Oksuz, Buyukozkan, andSatoglu (2017), Moussavi, Mahdjoub, and Grunder (2017) and Zhang, Tang, and Zhang (2018) explored this for the assembly-line-balancing problem. Moreover, Süer and Tummaluri (2008), Cheng and Chu (2012), Li, Huang, and Niu (2016), Rabbani, Akbari, and Dolatkhah (2017), Gong et al (2018) and Liu and Yang (2019) considered work/worker assignment problems in production systems and maintained that the differences between workers in terms of skill level and proficiency can impact the task processing time.…”

“…The classification in Table 3 shows that there are compelling evidences that workforce differences can largely impact the task processing time (Sotskov et al 2015) and consequently the cycle time (Moussavi, Mahdjoub, and Grunder 2017) and cost, including the total cost (Martignago, Battaïa, and Battini 2017) and training cost (McDonald et al 2009), and the throughput (Bentefouet and Nembhard 2013). Many of the selected papers acknowledge that time and cost are largely influenced by the differences between workers, particularly in terms of skill.…”
