Research scholars Kritika, Santosh, and Rishav from the Department of IEOR attended the 51st International Conference on Computers and Industrial Engineering (CIE51), organized at the University of New South Wales, Sydney, Australia. This event was held in collaboration with the Decision Sciences and Analytics Group at UNSW and the Centre for Sustainable Operations and Supply Chain Resilience at the University of Adelaide from December 9 to 11, 2024. They presented their following respective works
1. Kritika Karwasra presented the paper (co-authored with Prof. Narayan Rangaraj) titled “Optimizing Shipper Transportation: Analysing Allocation Policies for In-House and Outsourced Rail Rakes using Simulation Modeling”. The paper explores various allocation policies that shippers can use to decide between in-house and outsourced rail rakes. Through a simulation-based study, it evaluates different scenarios while accounting for uncertainties in demand, travel time, loading and unloading durations, and the availability of outsourced resources.
2. Santosh Palaskar presented the paper (co-authored with Prof. Nandyala Hemachandra and Prof. Narayan Rangaraj) titled "Hierarchical Aggregation-wise Multivariate Time Series Forecasting for Supply Chain". Proposed multivariate time series forecasting method that incorporates base forecast constraints and addresses challenges in bottom-level series forecasting. The approach focuses on MTSF for bottom-level nodes sharing the same parent, achieving up to a 12% reduction in RMSE and a 9.7% reduction in MAE across three datasets compared to state-of-the-art methods.
3. Rishav Deval presented the paper (co-authored with Prof. Jayendran Venkateswaran) titled "Emission-Constrained Production and Inventory Control System (EC-PICS): A Cost-Based Analysis Under Dynamic Environmental Regulations." The presented paper provides an overview of structural changes to inventory management systems under constrained environmental regulations and discusses the simulation-based cost dynamics of these structural changes.
About Computers and Industrial Engineering Conference:
As an annual event, CIE51 aimed to gather researchers to disseminate and discuss state-of-the-art advancements in the areas of industrial engineering, supply chain management, operations management, computer science, manufacturing, management, and other related areas. The conference received approximately 325 submissions (both full papers and abstracts) for presentation from around the world.
