OPERATIONAL PLANNING AND IMPROVEMENT OF INFECTED WASTE COLLECTION ROUTES BY USING THE SAVING ALGORITHM METHOD: A CASE STUDY OF ABC CO., LTD.

Abstract

This research aims to study the operation and use of ECRS principle for reducing operating procedures that cause wastefulness of ABC company. Furthermore, the research was conducted to apply the Saving Algorithm method for improving time efficiency in routing of infected waste collection. Constrain of this research, the employee's operating time of 8 hours per day and limitation of speed is 80 kilometers per hour in order to compare the result between its current routing and rerouting with the Saving Algorithm method. The result showed that with the improvement of operational procedures, the collection time reduced from 8.24 hours to 8.08 hours with the total time reduction at 1.94%. The routing with the Saving Algorithm method reduced from 271 hours to 226.15 hours per month with the total time reduction at 16.55%. In summary, this application can effectively manage the vehicle plant division so as to support its future growth.
