Vendor managed inventory (VMI) is one of the most widely discussed partnering initiatives for improving multi-firm supply chain efficiency. VMI became one of the key programs in the grocery industry's pursuit of "efficient consumer response" and garment industry's "quick response". And at present, we know that many companies have successfully improved their supply chain performance by implementing the approach of VMI. With VMI, vendors specify delivery quantities sent to customers through the distribution channel using data obtained from electronic data interchange (EDI). A model for a VMI system is constructed where vendors can manage stock at the retailers' locations. A supply chain system in this model has been constructed which is composed of m vendors and n identical retailers. Vendors' and retailers' profits can be calculated for different retailer order batch policies. In this model, we use several parameters because the distances between the vendors and retailers are not same; the stock costs of vendors can vary; the kinds, prices and quantities of retailers' ordering can vary; stock-out contributions of retailers to the vendors can vary. The objective of the model is to minimize total inventory costs for vendors. The model also can analyze how alternative policies can minimize vendor and retailer profits. A simulation example is given

Radio frequency identification provides the services to gather and process product data at a rate that is unprecedented. When integrated as a component of electronic data interchange it can be a powerful resource to those that harness its potential. Unlike the profit-driven retail industry the underlying supply chain revolves around meeting service levels and reducing costs at the bottom line. Operating costs are either incurred or reduced according to how efficiently inventory is moved. Limited visibility and lack of flexibility are often factors which cause opportunities for time reduction across the pipeline to go unrecognized. The services gained through integration of RFID contributes to better pipeline management, visibility, improved forecasting, flexibility and bottom line reduction thus providing the means to gain a competitive advantage. RFID is both flexible and scalable and can therefore be implemented and integrated according to needs of the user. RFID is also a subset radio frequency technology which enables smart shelves and environment sensors. By creating a ubiquitous data gathering environment, which can be in close proximity to consumers, it simultaneously taps the need for data management, data sharing relationships and concerns over customer privacy

Logistics system, being one of the most important sectors that offer substantial supports to national economy, its reliability and stability has a direct impact on the healthy development of national economy. With demand of modern integrated logistics service upgraded, the traditional chain-like structure of logistics system is being developed into a networked one. Taking the perspective of logistics service, the research conducts a deep analysis on the connotation of logistics network service and the basic structure of logistics network based on service relationship. Then the reliability of service provider/demander of logistics network is calculated. The research puts an emphasis on calculation of integrated logistics service reliability offered by logistics network with network-optimizing functions to fulfil optimal allocation of resources and concludes with some research suggestions

Over the past ten couple of years, there is a variety of effort models proposed by academicians and practitioners at early stage of software development life cycle. Some addressed that efforts could be predicted using lines of codes (LOC) and COCOMO, others emphasized that it could be made using function point analysis (FPA) or others. The study seeks to develop a model that estimates software effort by studying and analyzing small and medium scale application software. To develop such a model, 50 completed software projects are collected from a software company. With the sample data, design team factors are identified and extracted. By applying them to simple regression analyses, a prediction of software of effort estimates with accuracy of MMRE=9% was constructed. The results give several benefits. First, the estimation problems are minimized due to the simple procedure used in identifying those factors. Second, the predicted software projects are only limited to a specific environment rather than being based upon industry environment. We believe the accuracy of effort estimates can be improved. According to the results analyzed, the work shows that it is possible to build up simple and useful prediction model based on data extracted at the early stage of software development life cycle. We hope this model can provide valuable ideas and suggestions for project designers for planning and controlling software projects in near future

Outsourcing is regarded as a new strategy to gain more competence under the condition of limited resources. Especially offshore outsourcing has been popular since 2001 in the developed countries. More often than not, outsourcing models and methods have been the focus of discussion, the cost of outsourcing is underestimated. This paper tries to discuss the cost issues when engaged in business process outsourcing for information technology (IT) service companies. Firstly, this paper presents the incentives and contents of outsourcing, then analyzes the dilemma of outsourcing, following presents the transaction costs theory. Lastly, this paper finds the solution to save the costs of outsourcing for IT service companies from the different points of view, such as returns from scale, returns from skill, returns from relationship, returns from models, etc

It is a new approach to obtain the time-based competitive advantage for enterprises through the third party logistics (TPL) providing distribution service. But a more important question that has to be considered is that the pattern of distributing by TPL whether will increase the logistics cost. A comparison of logistics costs of TPL agential distribution pattern and self-operation distribution pattern is presented in this case study. The study results showed that TPL agential distribution can reduce the logistics cost as well as form time-based competitive advantage; three parts of logistics costs are all affected and decreased; furthermore, there is a trend of cutting down both the number of warehouses and warehouse's managers after the TPL agential distribution pattern is brought into effect

Optimization theories and algorithms such as linear programming have long been used to find the best solutions in production planning and scheduling. Web services are software functions that can be accessed and called over the Internet. The network enabled optimization system (NEOS) has been developed at Argonne National Laboratory. NEOS consists of next generation optimization servers as Web services. Most current users of NEOS are researchers and scientists. We are building a production planning and optimization Web services for manufacturing planners to be able to leverage the state of the art NEOS and generate globally optimized cross supply chain network, real time, and flexible plans

This paper demonstrates the use of social network theory in understanding the degree of coordination in port supply chains. Three port supply chains are used to illustrate that port supply chains are, in fact, social networks and that their success is strongly influenced by the level of coordination and cohesion in their networks. Of the three port supply chains in this study, those with higher degrees of cohesion and coordination tend to exhibit higher operational performance. While causation was not demonstrated, this paper provides the foundation and groundwork for further empirical study into the use of social network theory to study supply chain relationships and port supply chain integration

Information and communication technologies (ICTs) are now widely accepted by developing countries as a critical tool in their efforts, so policy makers should develop ICT policies or e-policies in order to monitor and evaluate political, socio-economic and cultural impacts of ICT and also measure progress in the use of ICTs to achieve the development strategies and policies. The paper focuses on the ICT's impacts as an important part in developing e-policies, including a comprehensive model based on system approach, appropriate frameworks for determining affecting and affected elements of ICT and a conceptual framework for analyzing and prioritizing different dimensions of the society. The paper is helpful to development planners because their concern is the use of ICTs for the community and they measure the benefits and outcomes of using ICTs in development terms
