Abstract

Penelitian ini mengembangkan model Common Replenishment Epoch (CRE) dari Viswanathan dan Piplani (2001) dengan mempertimbangkan kelayakan konsolidasi pengiriman. Dalam model CRE tersebut, vendor menggabungkan replenishment order dari buyer dengan menetapkan jadwal replenishment pada waktu tertentu dan menawarkan insentif berupa diskon kepada buyer agar bersedia mengikuti interval replenishment sesuai dengan CRE. Namun, model CRE tersebut belum membahas mekanisme pelaksanaan CRE pada tahap operasional. Untuk mengisi kesenjangan tersebut, penelitian ini mengembangkan model dan algoritma mekanisme pelaksanaan CRE dengan mempertimbangkan kelayakan konsolidasi pengiriman. Pada model yang diusulkan, replenishment order dilakukan pada kelipatan Power of Two (PoT), yaitu 2^k, dengan k = 0, 1, 2, ... dari periode dasar. Pengiriman order dari buyer dengan interval replenishment yang sama akan dikonsolidasikan dengan menentukan jenis kendaraan dan rute yang optimal. Diskon diberikan secara selektif, yaitu hanya kepada buyer yang order-nya dapat dikonsolidasikan dalam pengiriman, untuk meminimalkan total biaya. Dengan menggunakan contoh numeris, dilakukan evaluasi terhadap keunggulan model koordinasi yang diusulkan dibandingkan dengan kebijakan multiple integer, yaitu kebijakan yang memungkinkan replenishment dilakukan pada kelipatan berapa pun dari periode dasar. Pada bagian akhir penelitian, dilakukan analisis sensitivitas untuk mengetahui perilaku model yang diusulkan berdasarkan beberapa skenario.

This study extends the Common Replenishment Epoch (CRE) model developed by Viswanathan and Piplani (2001) by considering the feasibility of shipment consolidation. In the CRE model, the vendor consolidates buyers' replenishment orders by establishing a replenishment schedule at specific times and offering incentives in the form of discounts to encourage buyers to follow the replenishment intervals specified by the CRE policy. However, the existing CRE model does not address the operational mechanism for implementing the CRE strategy, particularly the feasibility of shipment consolidation. To address this gap, this study develops a model and heuristic algorithm for implementing the CRE strategy while considering shipment consolidation feasibility. In the proposed model, replenishment orders are placed at multiples of the Power-of-Two (PoT) policy, namely 2^k, where k = 0, 1, 2, ... of the base period. Orders from buyers with the same replenishment interval are consolidated by determining the optimal vehicle types and delivery routes. Discounts are offered selectively, only to buyers whose orders can be consolidated into the same shipment, in order to minimize total costs. Numerical examples are used to evaluate the advantages of the proposed coordination model compared with the multiple-integer policy, in which replenishment can be conducted at any integer multiple of the base period. Finally, a sensitivity analysis is conducted to examine the behavior of the proposed model under several scenarios.
