Integrated inventory system with freight costs and two types of quantity discounts

Abstract

In this paper, we investigate an integrated inventory model for single supplier-buyer considering stochastic demand. We consider two quantity discounts with freight environment. The objective is to minimise the integrated total cost incurred by the supplier and buyer. Freight costs are the function of shipping weight and distance with two transportation modes: truckload (TL) and less-than-truckload (LTL) shipments. We develop two optimal models considering all-units quantity discount and incremental quantity discount. The study shows how freight costs and the two discount policies affect the total cost of the supplier and the buyer. Numerical examples are used to illustrate of two models.

Pengaruh Live Streaming Selling, Review Product, Dan Discount Terhadap Minat Beli Konsumen Pada E-Commerce Shopee

“…Discount adalah praktik umum bagi pemasok untuk menawarkan harga satuan yang lebih rendah pada pesanan yang lebih besar jumlah sebagai insentif ekonomi bagi pembeli untuk membeli dalam ukuran lot yang lebih besar. Manfaat dari penjualan dalam jumlah yang lebih besar dengan mengurangi pemrosesan dan pengaturan pesanan per unit biaya dan dengan meningkatkan volume (Wangsa, 2020). Faktor -faktor, seperti: harga komoditas, layanan purna jual, iklan, dan kualitas produk secara langsung dapat mempengaruhi permintaan pasar terhadap produk (Sarkar, 2020).…”

Inventory decisions on the transportation system and carbon emissions under COVID-19 effects: A sensitivity analysis

“…The model considered a less-than-truckload transportation mode. Wangsa and Wee, 2018 , Wangsa and Wee, 2020 considered freight forwarding services that accumulate products during distribution. Recently, many authors have incorporated carbon emissions from transportation activities to develop green inventory models.…”

Robust Optimization for a Bi-Objective Green Closed-Loop Supply Chain with Heterogeneous Transportation System and Presorting Consideration

“…Most of the model input parameters were adopted from the literature [20], which are based on realistic data. Vehicle capacity and CO 2 emissions were calculated for road transport operations as in Mohammed et al [49], and the transportation cost based on vehicle type was calculated as in Wangsa and Wee [59] as shown in Table 2. The number of returned products, selling price of refurbished products at customer zones, operations costs, and weight of returned products are presented in Table 3.…”
