Selecting the Optimal Green Supplier and Order Allocation under Linear Discount

Abstract

Selecting the right supplier can be one of the most critical decisions for manufacturing firms. Strategic issues often dictate whether a company thrives or fails. When making important decisions, certain people consider the importance of green-friendly criteria before selecting a supplier. Various companies prioritize green suppliers in their selection process. This work considers the grey method of choosing green suppliers by considering the excellence and weakness. In addition to the green suppliers, the allocation of orders is carried out. The green vendors are focused on utilizing grey, and the demand is assigned by utilizing linear discounts for multiple products and time periods. This work introduces an integrated model with multiple products and time periods for determining demand using green criteria. The outcome of this work is to assign orders to the best suppliers to increase total purchase value while reducing total purchase costs. Then, the method is depicted with a numerical model in a linear discount scenario. A sensitivity analysis was carried out. TVP and TCP differences in order quantity and optimum solution are illustrated in the sensitivity analysis. The numerical model is programmed and resolved by LINGO 18.

Green Supplier Assessment and Selection for Sea Cucumber (Apostichopus japonicus) Processing Enterprise: Case Study in China

“…Therefore, it is still necessary to comprehensively consider the indicators on three levels to comprehensively evaluate the five alternative suppliers. The fuzzy vector single-valued weight assignments are of three levels, q 1 : high level, q 2 : mid level, and q 3 : low level, and according to Equation ( 8), the set of assignments Q can be expressed as follows: Q = q 1 , q 2 , q 3 (19) The weights of the three levels are assigned as q 1 = 3, q 2 = 2, q 3 = 1. Therefore, the intervals of the fuzzy vector uniformization results can be obtained in [1][2][3].…”

“…Lima Junior et al [18] argue that supplier selection has become very critical to the performance of organizations and supply chains. Lakshmanpriya et al [19] state that selecting the right supplier can be one of the most critical decisions for manufacturing firms and that various companies prioritize green suppliers in their selection process. Verma et al [20] show that green supplier selection will help in increasing the environmental sustainability of a company.…”

Online and Offline Model for Housekeeping Order Assignment Based on Dynamic Programming Algorithm

“…In 2022, Lakshmanpriya et al [19] introduced a comprehensive model including multiple products and time cycles to determine the demand based on green standards and allocate orders to the best suppliers, in order to increase the total procurement value while reducing the total procurement cost. Jiang et al [20] proposed a network freight order allocation mechanism under carbon tax constraint and established an optimization model for order allocation under carbon tax constraint, which was solved using a 0-1 integer programming algorithm, and the order allocation arrangement for online freight platforms under carbon tax constraints was more economical and environmentally friendly.…”

Evaluating Suppliers Using AHP in a Fuzzy Environment and Allocating Order Quantities to Each Supplier in a Supply Chain

“…e authors studied a scenario in which purchasers must estimate the number of products to order of each supplier in every period to achieve the production plan's requirements. However, they must also adhere to the given constraints [17,18].…”
