An inverse economic lot-sizing approach to eliciting supplier cost parameters
نویسندگان
چکیده
This paper proposes an inverse lot-sizing model for eliciting the cost parameters (the setup, holding, and backlog costs) of a supplier from earlier demand vs. optimal lot-size pairs. It is assumed that the supplier solves a single-item, multi-period, uncapacitated lot-sizing problem with backlogs to optimality to calculate its lot-sizes, and the buyer is aware of this fact. The inverse optimization problem is reformulated to a linear program. The approach is evaluated on a set of randomly generated problem instances.

A Multi-objective Mathematical Model for Sustainable Supplier Selection and Order Lot-Sizing under Inflation
Recently, scholars and practitioners have shown an increased interest in the field of sustainable supplier selection and order lot-sizing. While several studies have recently carried out on this field, far too little attention has been given to formulating a multi-objective model for the integrated problem of multi-period multi-product order lot-sizing and sustainable supplier selection under i...
متن کاملJOINT ECONOMIC LOT SIZING PROBLEM IN A TWO ECHELON PRODUCTION SYSTEM WITH FINITE PRODUCTION RATE AND LEAD TIME
In this study, a two-echelon supplier-manufacturer system with finite production rate and lead time is proposed. It is assumed that shortage is not permitted and the lot size of manufacturer (second echelon) is m-factors of the lot size of supplier (first echelon) and supplier can supply the manufacturer’s lot size in several shipments in each cyc...
متن کاملModeling and Analyzing Incremental Quantity Discounts in Transportation Costs for a Joint Economic Lot Sizing Problem
Joint economic lot sizing (JELS) addresses integrated inventory models in a supply chain. Most of the studies in this field either do not consider the role of the transportation cost in their analysis or consider transportation cost as a fixed part of the ordering costs. In this article, a model is developed to analyze an incremental quantity discount in transportation cost. Appropriate equatio...

Sharing common production, resources and services to reduce cost are important for not for profit operations due to limited and mission-oriented budget and effective cost allocation mechanisms are essential for encouraging effective collaborations. In this paper, we illustrate how rigorous methodologies can be developed to derive effective cost allocations to facilitate sustainable collaboratio...
متن کاملEconomic order quantity model for growing items with incremental quantity discounts
Certain inventory items are living organisms, for example livestock, and are therefore capable of growing during the replenishment cycle. These items often serve as various saleable food items downstream in supply chains. The purpose of this paper is to develop a lot sizing model for growing items if the supplier of the items offers incremental quantity discounts. A mathematical model is derive...
