Abstract
Logistics network design provides an optimal platform for efficient and effective supply chain management (SCM). Lack of stated roles and activities among the stakeholders and economical reverse logistics network design problems in the industry can cause waste in Ethiopia. Based on the average 3 years battery life service from 2000 GC obtainable vehicles amounting to 1,147,244 data in a country, 382,415 pcs of SLABs are found in 2023. Which is less than 40 percent potential from obtainable spent production. This research aims to develop an economical and profitable reverse logistics network design system for lead recycler industries from spent lead acid batteries. Both primary and secondary data collection sources were used in this study. For secondary sources use manuals, guidelines, different annual reports, and literature relevant to the research, and for primary data sources Surveys and questionnaires, and observation were used to acquire relevant data for the study. Determining the customer demand and the spent product obtainable region, facilities levels, and industry recycling capacity to achieve integrated forward and reverse logistics network design to obtain the least cost design and maximum profit. This study used the framework proposed on network design configuration for reverse logistics based on five significant participants in the network including consumer, maintainer, retailer, collector and distributor, and recycler. The designed reverse logistics model is simulated by integrating the existing using the proposed multi-echelon SIM and validated by using available SLAB data collected in six regional collection centers, using one recycling factory, one supplier, and twenty customers, and simulation used in these experiments. Findings of one-year simulation experiments highlight that the operational performance of profit has been increased from 67,344,439.94 to 76,503,976.32, which shows a substantial improvement in operational performances for the finances compared to the existing network, particularly in: Facility cost, Inventory cost, and Transportation Cost. The identified existing facilities will guarantee enhanced cost-effectiveness of distribution operations with potential cost savings in transportation and warehousing without additional charge for the activities to back the spent products when measured via simulation.
