Reverse Logistics Network Design and Simulation for Automatic Teller Machines Based on Carbon Emission and Economic Benefits: A Study of the Anhui Province ATMs Industry

Abstract

In recent years, mobile payments have gradually replaced cash payments, resulting in a gradual decline in the number of automatic teller machines (ATMs) demanded by banks. Through investigation and analysis, we determine four means to deal with decommissioned ATMs, and construct thereafter an ATM reverse logistics (RL_ATMs) network model, which includes suppliers, producers, warehouses, operators, maintenance centers, collection and inspection centers, disposal centers, remanufacturing centers, and recycling centers. This model is further expressed as a mixed integer linear programming (MILP) model. Given that an ATM recycling network has planned and batched characteristics, a percentage diversion method is proposed to transform a real multi-cycle problem to a single-cycle problem. The RL_ATMs network constructed in this study presents the two forms of ATMs, functional modules and the entire machine. We used the actual situations of the related companies and enterprises in Anhui Province and its surrounding areas, as well as major banks’ ATMs, as bases in using the LINGO software to solve the proposed MILP model with the objective function of minimizing costs and environmental emissions, and obtain the relevant companies’ launch operations. Lastly, we analyzed the relationship between coefficients in the percentage diversion method and calculation results, cost, and carbon emissions. Accordingly, we find that the number of remanufacturing and maintenance centers has no evident impact on the objective function, transportation costs account for a large proportion of the total cost, and emissions tax is small.

Revolusi Perbankan Digital: Game Changer Dalam Era Digitalisasi

“…Digitalisasi perbankan terjadi ketika m-banking diperkenalkan, berbagai teknologi digital seperti smartphone, internet, dan software dari m-banking diperlukan; Hal ini menjadikan perbankan digital sebagai game changer dalam perekonomian Indonesia. Sejak pandemi Covid19 melanda Indonesia pada tahun 2020 yang seluruh aktivitasnya dilakukan secara jarak jauh sehingga memaksa kehidupan harus beradaptasi dengan teknologi dan beraktivitas secara online, kondisi tersebut memiliki potensi yang cukup besar dalam mengembangkan digitalisasi perbankan (Marcu, 2021;Rochmah & Ernawati, 2022;Song et al, 2021). Banyaknya nasabah perbankan yang melakukan aktivitas transaksi dari rumah, mendorong bank untuk terus melakukan inovasi atau pemutakhiran m-bankingnya.…”

Model for Reverse Logistic Problem of Recycling under Stochastic Demand

“…Reverse logistics aims to carry out the logistics processes (the flow of products and materials from the end consumer to the supplier) in the most cost-effective, efficient way. In general, reverse logistics refers to the operations carried out to return products that have lost their original use value to manufacturers or special processing areas [17].…”
