Simulation Modeling of Integrated Supply Chain Logistics Networks

The present work describes modeling and simulation of reverse supply chain logistics network for collection of End-of-Life (EOL) products for a manufacturing company of North India. The company involved in production of automobile batteries for commercial use. Stress is being given on design and development integrated forward and reverse supply chain logistics network for battery recycling operation. Simulation modeling, presented in this work allows the user to analyze the future performance of the logistics network and to understand the complex relationship between the parties involved in the business. The results of the simulation suggest that the model calculates operation cost, cycle time, Queue length, transfer time, transfer cost, and resource utilization in a predictable manner. In this project, the simulation model was developed by using Arena 11.0 simulation package.

SCM: An integrated approach for effective management: A case study of manufacturing unit

In the present work the current supply chain of the company has been thoroughly studied to sort out the excess inventory related problem and a new model of supply chain of the company has been proposed with recommendations. A demand forecasting analysis has been done for solving inventory pileup problem in the store. The Bullwhip effect is quantified and recommendations are given to reduce variation in the demand and supply of company. To sort out problem of irregularities in the supply of raw materials a proper vendor rating method has been designed for the company and ABC analysis in the inbound store has been proposed to streamline the purchasing activity of the company. The bar-coding system has been recommended with proper validation to the company for solving the problem of wrong issuing of the materials to different sections. This work has been done for a small medium scale manufacturing company of Northern India.

Reverse logistics network design for spent batteries: a simulation study

End of life (EOL) product management, which encompasses reuse, remanufacturing and materials recycling, requires a structured reverse logistic network in order to collect products efficiently at the end of their life cycle. This work describes modelling and simulation of reverse logistics network design for collection of spent batteries for Sangrur District of North India. To compare different order assignment, a simulation model of forward and reverse logistics networks has been developed. Several simulation experiments have been designed to analyse impact of the system design factors on the operational performance of the reverse logistics system. The simulation results show that the model presented in this paper calculates the battery collection cost, transfer time, transfer cost, and resource utilisation in a predictable manner. Moreover, it provides a tool to understand how the system behaves by carrying out ‘what-if’ assessments and to identify which parameters are most important for more detailed an...
