The Counterfeit Electronics Problem  [PDF]
Michael Pecht
Open Journal of Social Sciences (JSS) , 2013, DOI: 10.4236/jss.2013.17003
Abstract:

Counterfeit electronics have been reported in a wide range of products, including computers, telecommunications equipment, automobiles, avionics and military systems. Counterfeit electronic products include everything from very inexpensive capacitors and resistors to costly microprocessors to servers. This paper describes the counterfeit electronic products problem, and discusses the implication of counterfeit electronics on the electronic supply chain. We then present counterfeit detection and prevention techniques for electronics.

A Preliminary Examination of Risk in the Pharmaceutical Supply Chain (PSC) in the National Health Service (NHS)  [PDF]
Liz Breen
Journal of Service Science and Management (JSSM) , 2008, DOI: 10.4236/jssm.2008.12020
Abstract: The effective management of pharmaceuticals in the National Health Service (NHS) is critical to patient welfare thus any risks attached to this must be identified and controlled. At a very basic level, risks in the pharmaceutical supply chain are associated with product discontinuity, product shortages, poor performance, patient safety/dispensing errors, and technological errors (causing stock shortages in pharmacies) to name but a few, all of which incur risk through disruption to the system. Current indications suggest that the pharmaceutical industry and NHS practitioners alike have their concerns as to the use of generic supply chain strategies in association with what is perceived to be a specialist product (pharmaceuticals). The aim of the study undertaken was to gain a more realistic understanding of the nature and prevalence of risk in the Pharmaceutical Supply Chain (PSC) to be used as a basis for a more rigorous research project incorporating in-vestigation in the UK, Europe and USA. Data was collected via a workshop forum held in November 2005. The outputs of the workshop indicated that there were thirty-five prevalent risks. The risks were rated using risk assessment catego-ries such as impact, occurrence and controllability. The findings indicated that the risks identified are similar to those prevalent in industrial supply chains, regardless of the idiosyncrasies of pharmaceuticals. However, the group consen-sus was that caution must be applied in how such risks are addressed, as there are aspects of the product that highlight its uniqueness e.g. criticality.
Information Sharing in a Supply Chain with Horizontal Competition: The Case of Discount Based Incentive Scheme  [PDF]
Birendra K. Mishra, Srinivasan Raghunathan
Theoretical Economics Letters (TEL) , 2012, DOI: 10.4236/tel.2012.24069
Abstract: Li [1] examined the incentives for information sharing in a two-level supply chain in which there are a manufacturer and many competing retailers. Li showed that direct and leakage effects of information sharing discourage retailers from sharing their information and identified conditions under which demand information sharing can be traded. The purpose of this note is to show that full information is the equilibrium if the manufacturer adopts a discount based incentive scheme instead of the side-payment scheme used by Li. The discount-based scheme eliminates the direct as well as leakage effects. Discount based scheme is attractive because similar schemes are commonly used in practice and it results in Pareto-efficient information sharing equilibrium that has a higher social welfare and consumer surplus than the no information sharing scenario. The total social benefits and consumer surplus are higher in discount based incentive scheme. Consequently, many of the key results of Li are critically dependent on the assumption that the manufacturer uses side payment for information.
Sustainable Supply Chain Management Practices and Operational Performance  [PDF]
Maruf Hasan
American Journal of Industrial and Business Management (AJIBM) , 2013, DOI: 10.4236/ajibm.2013.31006
Abstract:

Sustainable supply chain management has emerged as a key approach for enterprises aiming to become environmentally sustainable. The study will investigate the kinds of environmental management practices that are undertaken by companies in greening the supply chain and how these practices affect the environmental and operational performance of the companies. The study provides additional insight into the growing field of literature examining the relationships between environmental policies and operational performance.

Risk Migration In Supply Chain Inventory Financing Service  [PDF]
Zheng Qin, Xiaochao Ding
Journal of Service Science and Management (JSSM) , 2011, DOI: 10.4236/jssm.2011.42026
Abstract: Inventory financing affects the risks of both for banks and supply chain companies. Traditionally, supply chain research focus more on material flow than financial. We construct a supply chain financing risk-information migration model (RMM). In this model, we discussed the preconditions to adopt inventory financing when the enterprises are facing cash constraints. And we simulated the whole operate of supply chain and bank behavior with Matlab. The simulation result shows if loan conditions are satisfied, the total risk value is reduced. Risk migration happens in the financing process. In this process, information-risk proportions are more reasonable.
A Modeling Framework for the Planning of Strategic Supply Chain Viewed from Complex Network  [PDF]
Jiangbo Zheng
Journal of Service Science and Management (JSSM) , 2009, DOI: 10.4236/jssm.2009.22016
Abstract: Based on the theory of complex network, this paper focuses on the planning of logistics nodes for strategic supply chain. I propose a practical mathematical modeling framework that simultaneously captures many practical aspects but still understated in the existing literatures of network planning problems. Moreover, capacity expansion and reduction sce-narios are also analyzed as well as modular capacity shifts for the fluctuation of demands. So this paper is of impor-tance for the research of network planning in strategic supply chain systems.
Influence of Lateral Transshipment Policy on Supply Chain Performance: A Stochastic Demand Case  [PDF]
Jingxian Chen, Jianxin Lu
iBusiness (IB) , 2010, DOI: 10.4236/ib.2010.21009
Abstract: Considering the supply chain consists of one supplier and two retailers, we construct the system’s dynamic models which face stochastic demand in the case of non-lateral transshipment (NLT), unidirectional lateral transshipment (ULT) and bidirectional lateral transshipment (BLT). Numerical example simulation experiments of these models were run on Venple. We adopt customer demand satisfaction rate and total inventory as performance indicators of supply chain. Through the comparative of the simulation results with the NLT policy, we analyze the influence of ULT policy and BLT policy on system performance. It shows that, if retailers face the same random distribution demand, lateral transshipment policy can effectively improve the performance of supply chain system; if the retailers face different random distribution demand, lateral transshipment policy cannot effectively improve the performance of supply chain systems, even reduce system’s customer demand satisfaction rate, and increase system inventory variation.
Forest Biomass Availability Analysis and Large-Scale Supply Options  [PDF]
Tapio Ranta, Olli-Jussi Korpinen, Eero J?ppinen, Kalle Karttunen
Open Journal of Forestry (OJF) , 2012, DOI: 10.4236/ojf.2012.21005
Abstract: Finnish forest companies aim to produce biodiesel based on the Fischer-Tropsch process from forest residues. This study presents method to evaluate biomass availability and supply costs to the selected biorefinery site. Forest-owners’ willingness to sell, buyers’ market share, and regional competition were taken into account when biomass availability was evaluated. Supply logistics was based either on direct truck transportation deliveries from forest or on railway/waterway transportation via regional terminals. The large biomass need of a biorefinery demanded both of these supply structures, since the procurement area was larger than the traditional supply area used for CHP plants in Finland. The average supply cost was 17 €/MWh for an annual supply of 2 TWh of forest biomass. Truck transportation of chips made from logging residues covered 70% of the total volume, since direct forest chip deliveries from forest were the most competitive supply solution in terms of direct supply costs. The better supply security and lower vehicle capacity needs are issues that would favour also terminal logistics with other raw-material sources in practical operations. One finding was that the larger the biomass need, the less the variation in biomass availability and supply costs, since almost the whole country will serve as a potential supply area. Biomass import possibilities were not considered in this study.
Food Supply Chain Safety Risk Prevention and Control: Based on the Behavioral Perspective  [PDF]
Yong-Sheng Liu, Rong Yu, Xiang-Xiang Lin
Journal of Service Science and Management (JSSM) , 2012, DOI: 10.4236/jssm.2012.53031
Abstract: Food supply chain is characterized by the complexity of covering a large range of aspects, which determines the difficulty of its safety risk prevention and control. Every step in food supply chain involves human activities, therefore the human participation becomes one of the critical elements that impact the food supply chain safety risk. From the perspective of human behavior as a cut-in point, the matter of food supply chain safety risk prevention and control is discussed and analyzed, referring to related theories of organizational behavior. Based on the discussion on attitude and motivation, two main factors that influence human behavior, approaches of controlling human behavior are summarized from two aspects, which are respectively correcting the food supply chain participants’ attitudes and providing them with incentives, so as to reach the goal of food supply chain safety risk prevention and control.
