Performance and Improvement of Production Line Function Using Computer Simulation (Case Study: An Iron Foundry)

Abstract

Using the accurate methods and tools for evaluation of function in different areas is of great importance. In recent years, much more studies have been done on the nature and methodology of function evaluation in organizations and its improvement. This study aimed to evaluate and improve the function of production line through computer simulation in one of the iron foundries in Iran. For this purpose, at first data has been gathered on the basis of timing with chronometer for each one of the production line machineries and using this data, distribution functions governing the activity cycle of each one of these machineries have been determined; and then, using the required gathered data for computer simulation (taking the advantage of "ED" simulation software), a model was simulated to introduce the current situation of production line and the validity of simulated model was measured on the basis of production rate. And then, considering the criteria such as the production rate, average waiting time, machine utilization coefficient, production yield, production cost, production income and the production time production line function was evaluated. Finally, applying amendment changes on the simulated model improved model was offered.

Usulan Peningkatan Kapasitas dengan Meningkatkan Kinerja Lini Produksi Melalui Model Simulasi (Studi Kasus di PT X, Bekasi)

“…Simulasi menjadi sarana yang sangat populer untuk memecahkan permasalahan lini produksi. Heshmat (2013) mengamati lini produksi semen, Khalafi (2014) menunjukkan betapa efektifnya simulasi dalam menganalisis bottlenecks pada lini produksi industrial valve, Saidabad (2015) meneliti peningkatan laju produksi peleburan baja yang dipengaruhi faktor eksternal dan internal yang menggambarkan faktor-faktor yang tidak dapat dikendalikan dan yang sebaliknya. Hasil penelitiannya merekomendasikan hal-hal detil yang dapat dihasilkan dari studi simulasi seperti mengatur waktu makan dan membuat penyimpanan di antara stasiun kerja.…”

Definition of range of open applications for massive nodes in the stainless steel castings

“…Проте з такими перевагами ливарного виробництва, як відносна простота отримання й низька вартість виливків (особливо з чавуну), можливість виготовлення складних деталей з різних металів і сплавів, воно має низку істотних недоліків: передусім досить низька продуктивність праці, неоднорідність складу і знижена щільність матеріалу заготівки, та його нижчі, ніж заготівок, отриманих обробкою тиском, міцнісних характеристики [1].…”

“…Це призводить до дефіциту об'єму, який проявляється у вигляді таких дефектів, як усадочні раковини, утяжини, і т. д. [1][2][3][4].…”

Empirical Study of Foundry Efficiency Improvement Based on Data-Driven Techniques

“…Reduction of waste also raised researchers' attention, and statistical tools are used to optimize mechanical reclamation systems in cast iron foundry [15]. Computer simulation is another tool for the performance and improvement of the production line [16]. Machine learning technologies are also applied to improve foundry production quality [17,18], using decision trees, Bayesian Networks, and K-Nearest Neighbors algorithms.…”
