Inbound Logistics Management for a PVC Resin Manufacturer

Abstract

The main objective of this research is to enhance logistics operation of a Thai PVC manufacturer located in Rayong, where we will focus more on the domestic part involving with three different PVC products, that is, Palletized PVC, Flexible-bag PVC, and Tank car PVC. Based on the historical data collected in 2017, over 90 percent of the complaints was identified as delivery delays caused by comparatively long non-value added activities within the inbound logistics process, such as waiting in weighting-in process and over processing steps in delivery paper generation. In order to address these issues, truck scheduling and throughput time improvement initiatives had been suggested, each of which was assessed by a simulation software named Arena. Based on these initiatives, the company could potentially reduce the throughput time, i.e. the time from which a truck arrived till its departure from 180 minutes to 120 minutes, or approximated one-third of the current practice.
