Abstract

A queuing system is a mathematical model used to analyze the phenomenon where entities wait to receive services from one or more service providers. In this system, arriving entities will queue if the service is not immediately available and will be served according to a specific order or priority when the service becomes available. ABC Supermarket is a store that is always busy with customers. Besides having low prices, ABC Supermarket also provides daily necessities. The purpose of this research is to determine whether the cashier queue system implemented at ABC Supermarket is effective or not. This research uses the queue system method. This research concludes that the queue system at ABC Supermarket with 6 cashiers has an average ρ value percentage of 41.67%, which falls into the ineffective category. The most effective number of cashiers is 3, with an average r value percentage of 83.33%, which falls into the effective category. The purpose of queuing system analysis is to optimize the performance of the queuing process by determining the optimal number of service providers required.

Abstract

Optimalisasi distribusi merupakan salah satu bagian terpenting dalam logistik, dengan adanya optimalisasi pada bagian distribusi dapat menekan biaya logistik. Salah satu pendekatan untuk melakukan optimalisasi distribusi yaitu melalui penyelesaian masalah Vehicle Routing Problem (VRP). Biaya logistik salah satunya didapatkan dari jarak rute pengiriman. Penelitian menggunakan deskriptif kualitatif dengan yang mencakup identifikasi node (titik lokasi), jarak antar node, dan kapasitas kendaraan. Metode algoritma Nearest Neighbour digunakan dalam penyelesaian masalah VRP dan diimplementasikan melalui aplikasi yang dibangun menggunakan bahasa pemrograman Delphi. Tujuan utama penelitian ini adalah menghasilkan sebuah aplikasi untuk memudahkan pemahaman dan pembelajaran mengenai penyelesaian VRP. Hasil penelitian menunjukkan bahwa algoritma Nearest Neighbour dapat digunakan secara efektif untuk menyusun rute distribusi yang efisien. Aplikasi ini berguna sebagai media pembelajaran dalam mempelajari konsep distribusi logistik dan penggunaan algoritma Nearest Neighbour menunjukkan efisiensi dalam menyusun rute distribusi dalam skala sederhana.
