Dual-Channel Warehouse And Inventory Management With Stochastic Demand, Fawzat Alawneh, Guoqing Zhang
Dual-Channel Warehouse And Inventory Management With Stochastic Demand, Fawzat Alawneh, Guoqing Zhang
Mechanical, Automotive & Materials Engineering Publications
This study examines the inventory policy for the emerging dual-channel warehouse, which has a unique structure where the warehouse is divided into two areas: one for fulfilling online orders and the other for storing products and fulfilling offline orders. A multi-item inventory model was developed considering the warehouse capacity constraint, demand, and lead time uncertainty. Solution methods are provided for both uniform and normal distributions. Adopting the proposed inventory policy for a dual warehouse is cost effective and adds flexibility to the warehouse and supply chain. The study also offers managerial insights on some critical issues faced by companies operating …
A Three-Stage Model For Closed-Loop Supply Chain Configuration Under Uncertainty, Saman Hassanzadeh Amin, Guoqing Zhang
A Three-Stage Model For Closed-Loop Supply Chain Configuration Under Uncertainty, Saman Hassanzadeh Amin, Guoqing Zhang
Mechanical, Automotive & Materials Engineering Publications
In this paper, a general closed-loop supply chain (CLSC) network is configured which consists of multiple customers, parts, products, suppliers, remanufacturing subcontractors, and refurbishing sites. We propose a three-stage model including evaluation, network configuration, and selection and order allocation. In the first stage, suppliers, remanufacturing subcontractors, and refurbishing sites are evaluated based on a new quality function deployment (QFD) model. The proposed QFD model determines the relationship between customer requirements, part requirements, and process requirements. In addition, the fuzzy sets theory is utilised to overcome the uncertainty in the decision-making process. In the second stage, the closed-loop supply chain network …
System Of Systems Perspective On Risk: Towards A Unified Concept, C. Ariel Pinto, Michael K. Mcshane, Ipek Bozkurt
System Of Systems Perspective On Risk: Towards A Unified Concept, C. Ariel Pinto, Michael K. Mcshane, Ipek Bozkurt
Finance Faculty Publications
Many systems and projects that concern systems engineers, engineering managers, and business managers today can be defined as system of systems (SoS), which are described as ambiguous, uncertain and dynamic, among others. In addition to the traditional view on risk identification, analysis and management, the concept of risk should be considered with respect to these systems of systems. The purpose of this paper is to analyse both fundamental concepts and recent publications in system of systems, business and engineering management, as well as risk analysis, modelling, and management for the purpose of better describing the concept of risk with respect …
