Analisis Dan Implementasi Metode Earliest Due Date (EDD) Untuk Meminimalisir Keterlambatan Dalam Proses Penjadwalan Perbaikan Kendaraan

Abstract

The scheduling of vehicle repair services carried out by most automotive companies is still ineffective and still uses a conventional process by calculating based on employee subjective without using a specific scheduling method. The problem that occurs in most automotive companies is that there is a delay in completing customer vehicle repair, so that it often passes the deadline for the customer's vehicle settlement agreement. The problem of delays occurs because they have not used a specific scheduling method so that there is no prioritized job determination. To solve this problem, a priority rule method is needed, namely by using the Earliest Due Date (EDD) method. The purpose of this research is to analyze and design a vehicle repair scheduling system using the Earliest Due Date (EDD) method, so that it will help minimize delays in the customer vehicle repair process. The data used is data from one of the automotive companies for the period of June 2020 with the stall parameter (the place for the vehicle being repaired) which is used for every day is always constant as much as 2 stalls. The results of the calculation of vehicle sample data using the Earliest Due Date (EDD) method show that the average delay (days) is significantly reduced from 4.17 days to 2.5 days, and the number of late jobs (days) is lower than 25 days to 15 days, with the number of late jobs getting lower, allowing the vehicle repair process to be on schedule.
