Researches on vendor-managed inventory (VMI) system rarely consider the relationships between demand rate and inventory level. This paper extended the previous research by considering the effects of stock-level-dependent demand on the benefits of VMI system. Models for items with stock-level-dependent demand were developed to compare the performance of a series supply chain system with and without...
Supply chains face risks from various unexpected events that make disruptions almost inevitable. This paper presents a disruption recovery model for a single stage production and inventory system, where the production is disrupted for a given period of time during the production up time. The developed model is a constrained nonlinear optimization program which we have solved using an evolutionary...
Cluster supply chain has the advantages of scale economy, brand effect and technological innovation. It is an important way to adjust, upgrade and optimize tourism industrial structure .The study on how the cluster supply chain to promote the optimization of the tourism industrial structure has a great practical significance for the sustainable development of tourism industry. This paper attempts...
Rapid technology advances have shortened the lifecycle of electronic products, resulting in the increasing number of discarded products in recent years. Due to the growing environmental concerns, an effective reverse logistics infrastructure is required to support the product recovery activities. In this study, a forward/reverse logistics model is developed to minimize the total cost of supply chain...
This paper discusses global optimisation from a business perspective in the context of the supply chain operations. A two-silo supply chain was built for experimentation and two approaches were used for global optimisation: a classical evolutionary approach and a cooperative coevolutionary approach. The latter approach produced higher quality solutions due to its use of communication between silos...
Globalization has prompted manufacturing firms to come to terms with environmental legislation and regulations, resulting in the manufacturing industry realizing the importance of adopting environmental friendly supply chain management (SCM) practices. A growing number of companies have realized that attaining effective SCM is only one side of the coin. The other side is to make SCM environmentally...
The information-sharing on supply chain is the basis for the supply chain management, while it has some risk. The existence of destructive risk is the main obstacles for the information-sharing among the members. There must weigh the profits and risks and seek to maximize the interests under the premise of controlling destructive risk effectively in the information-sharing on supply chain. The different...
This article focuses on the issue of participant selection in supply networks risk management. Though there are many ways and applications which are introduced to selection participant in viewpoint of risk management, the practical effect of these methods is not considerable full and satisfactory. In this paper, we introduce a non-linear programming(NLP) method based on multiplicative and fuzzy preference...
In view of the problem on the optimal theory of three parallel activities adjusted to sequencing activities, the existing references only have done some theoretical researches, and produced the optimal method regarding the special problems. All possible results that three parallel activities are adjusted to sequencing activities are studied. Some new concepts and new theories are true through proof...
Evaluating the performances of a Supply Chain is a hard task due to its decentralized structure and when one tries to take into account sustainable development issues. As a first step towards a realistic evaluation tool, in this paper, we provide a two-echelon supply chain model - a manufacturer and a 3PL provider - inspired from Jung, Chen & Jeong which optimizes the economic criterion (costs)...
Research regarding supply chain optimization has been performed for a long time. However, it's only in the last decade that the research community has started to investigate multi-objective optimization for supply chains. Supply chains are in general complex networks composed of autonomous entities whereby multiple performance measures in different levels, which in most cases are in conflict with...
In this paper, we propose a coordinated single-vendor multi-buyer supply chain model by synchronizing delivery and production cycles with trade credit option. The synchronization is achieved by scheduling the actual delivery days of the buyers and coordinating it with the vendor's production cycle. It can be shown that the synchronized cycles policy works better, in terms of total system costs, than...
To survive in today competitive environment, companies need to improve customer service while reducing costs. One way to address this challenge is to effectively and efficiently managing inventory. Companies carry inventory to ensure the level of customer service and avoid lost sales. However, holding inventory comes with costs such as inventory carrying cost and opportunity cost. There are several...
In this paper, we present a green reverse supply chain supernetwork model, which consists of I manufacturers, J distributors, M markets and N recyclers. Hereon this base, the optimality conditions for the manufacturers, distributors, the consumers and the recyclers are established respectively using the variational inequalities. Then we describe the optimization situation for the supply chain supernetwork...
This paper describes a simulation model of a multiechelon inventory cost optimization problem using Arena. The problem to minimize the total inventory cost throughout the system while satisfying end-customer service-level requirements is analyzed in detail by the simulation. There are three retailers, a distribution center and a manufacturer in the multi-echelon inventory system. Each member follows...
With the economic crisis background, the maintenance function has evolved from being centered on short term questions such as the use of resources and allocation of costs to strategic considerations such as asset profit enhancement and fast response to the market demand. In this paper, our objective is to jointly optimize the maintenance of a capacity-constrained node, it's feed node and inlet buffer...
With the development of e-technology and Internet, information technology is introduced to commercial activities as a tool, which creates a new business operation e-commerce. Meanwhile, Chinese entrepreneurs have gradually realized that there is no doubt that competition among the enterprises is becoming the competition among their supply chains under the economic globalization in 21st century. The...
ECLIPS is a European research project extending the state-of-the-art in supply chain management. The goal of the ECLIPS project is to establish a global cost reduction in the entire supply chain in an ingenious manner, while addressing the ongoing challenges within the industry. Nowadays companies are facing ever more complex supply chains, increased portfolio diversification and shortening product...
The optimization of supply chain distribution network need to consider many factors, especially useful information derived from distributors. In this paper, We consider a supply chain consisting of two layers, they are one manufacture and many distributors. Each distributor has full knowledge about his own value-added cost structure. The problem is to design the optimal distribution network for the...
The supply chain nowadays is more dynamic than before partly due to the information techniques and changes of consumer behaviors. This proposal analyzes the multiple objective optimization problems existing in the supply chain management, and the stochastic and dynamic circumstance of current supply chain. It presents a general overview of multi-objective optimization techniques, stochastic and dynamic...
