Supply chain coordination mechanisms under asymmetric information with retailer cost disruptions

A two-level supply chain model involving one supplier and one retailer with linear demand is developed, and supply chain coordination mechanisms under asymmetric information （the retailer＇ s cost structure is asymmetric information） are proposed by employing game theory in two scenarios： coordination mechanisms under asymmetric information in a regular scenario （without disruption）; and coordination mechanisms under asymmetric information in an irregular scenario （ with retailer cost disruptions）. It is optimal for the supply chain to maintain the original production plan and to guarantee a steadily running system if variations of retailer costs are sufficiently low and do not exceed an upper bound. This shows that the original production plan has certain robustness under disruptions. Decisions must be re-made if a retailer＇ s cost change is greater and exceeds an upper bound. Impacts of retailer cost disruptions on the order quantity, the retail price, the wholesale price and each party＇ s as well as the system＇ s expected profits are investigated through numerical analyses.

Measuring the Impact of Information Technology （IT） on Supply Chain Management （SCM） Through Indicators： An Exploratory Study

Enterprises are looking to adapt to this scenario focusing on performance, seeking to improve the level of service and reduce costs in an attempt to differentiate and increase the perceived value of their customers. A strong partner to achieve these goals is the information technology （IT）. IT has an important role in the performance of companies, providing a flow of information that makes the supply chain more robust and resilient, without compromising efficiency. To achieve the objective of this research, a survey of the literature on the four models was studied and then a field research with professionals was conducted in the areas of IT and supply chain management （SCM） of various companies of Sao Paulo. To collect the data needed for analysis, we used the exploratory research of a qualitative nature. Thus, we conclude that the use of IT impacts supply chain in five surveyed areas as planning, manufacturing, suppliers, customers, and delivery but does not impact the return area.

International Supply Chain Management （ISCM）： An Emergent Perspective on Internationalization Driven by Information and Communications Technology （ICT）

The focus of the article is on the contribution of the perspective of supply chain management （SCM） to the explanation of internationalization processes. The empirical study is based on case studies of 20 small- and medium-sized enterprises （SMEs） with international activities from China, India, New Zealand, and Singapore. All chosen firms were founded after 1980 in order to capture retrospectively the whole globalization process of each firm. All sample firms operate their supply chains （SCs） on the basis of information and communications technology （ICT）. Depending on size, strategy, business model, industry, and mindset of the managers, firms use ICT on a range from integrating individual functional areas to integrating the whole SC through enterprise resource planning （ERP） and customer relationship management （CRM） systems.

Coordinating pricing strategies in supply chain under asymmetric information and disruptions

The coordinating pricing strategies with asymmetric cost information under disruptions are investigated in a one-supplier-one-retailer supply chain system.While the retailer's cost structure is asymmetric information,supply chain pricing contract models(a wholesale price contract and an all-unit quantity discount contract)under asymmetric information are proposed by employing the principal-agent principle in a regular scenario.When the retailer's cost distribution is fluctuated by disruptions,we obtain the optimal emergency strategies of the supply chain under asymmetric information by considering deviation costs and show how to effectively handle the cost uncertainty.Using numerical methods,impacts of cost disruptions on the optimal wholesale price,the retailer price,the order quantity and the expected profits of the retailer,the supplier,as well as the total system are analyzed.It is found that the all-unit quantity discount policy can obtain better performance than the wholesale pricing policy.

Quantity discount contracts for supply chain coordination under asymmetric information and disruptions

The quantity discount contracts are investigated for a one-supplier-one-retailer supply chain with asymmetric information when the retailer's cost is disrupted. While the retailer's cost structure is asymmetric information, two all-unit quantity discount contract models, fixed expected-profit percentage discount(FEPD) and fixed wholesale-pricing percentage discount(FWPD) under asymmetric information are proposed in a regular scenario. When the retailer's cost distribution fluctuates due to disruptions, the optimal emergency strategies of supply chains are obtained under asymmetric information. Using numerical methods, the impact of cost disruptions on decisions about the regular wholesale price, discount wholesale price, order quantity and expected profits of the retailer, the supplier as well as the total system are analyzed. It is found that the FEPD policy is more robust and adaptable than the FWPD policy in disruption circumstances.

Quantity Discount Scheme in Supply Chain under Asymmetric Information

Quantity discount scheme plays an important role in supply chain management. The different quantity discount schemes under symmetric （full） information and asymmetric information, are analyzed by using principal-agent and optimal control theory. As a result, the research reveals that the optimal quantity discount solution under symmetric information is a special case of that under asymmetric information. At the same price, the critical value of quantity discount under asymmetric information is much lower than that under asymmetric information. Therefore, this leads to less cost for retailers and smaller profit for their supplier.

Research on logistics management system based on supply chain management

Generally, supply chain logistics is the unification of logistics, information flow and capital flow, logistics runs through the whole process of the supply chain. Logistics connects the individual enterprise in the supply chain and it is the bond of mutual cooperation between enterprises. In that way, the logistics management becomes an important part of the supply chain management system naturally. However, it is not so long since the theory of supply chain management and logistics management put forward so they are still being refined. Besides, it is lack of green philosophy in the logistics management of the supply chain and effect of logistics on the environment and resource efficiency do not be considered synthetically. Yet, methods to solve the problem that customers return items and waste materials have been excluded from the enterprises and business strategy. With the awareness that people should protect the environment and conserve resources enhanced and governments increase the intensity of environmental regulations constraints, the theory and practice of green logistics management are valued by the foreign supply chain management and logistics management theory community and the business community gradually.

Improving Supply Chain Strategies towards Mitigating the Effect of Crude Oil Theft and Pipeline Vandalism in the Nigerian Oil and Gas Industry: A Case Study of the Nigerian National Petroleum Corporation (NNPC)

Generically, SCM may be said to include all activities carried out to ensure proper functioning of the supply chain. The activities included in proper management of a supply chain broadly include logistics activities, planning and control of the flow of information and materials in a firm, management of relationships with other organizations and government intervention, However, crude oil theft and pipeline vandalism are established products supply chain disruptors in Nigeria which are rendering the task of running an efficient petroleum supply chain onerous. This paper aims to establish the importance of effective supply chain strategies for companies in the oil and gas industry with special focus on the Nigerian oil and gas sector and the strategies by which the state oil and gas corporation in this sector may mitigate disruptions to its supply chain. This study investigates the enhancement of supply chain strategies towards meeting the challenge of crude oil theft and pipeline vandalism, using the Nigerian National Corporation (NNPC) as a case study. Based on this study, data were collected from two sources: A summary of incident reports obtained from NNPC and an interview with personnel in the PPMC Department. Incident report refers to a report produced when accidents such as equipment failure, injury, loss of life, or fire occur at the work site. Content analysis is utilized to evaluate data obtained from interview responses, CBN financial stability reports, NDIC annual reports, circulars, banking supervision reports and implementation guidelines. The study found out that NNPC should endeavor to sustain its value chain and ward of pipeline vandals and crude oil thieves by engaging in community partnership, detailing security outfits to ensure its pipelines’ right of way and bridging. Concluded that the oil supply chain of the Nigerian National Petroleum Corporation has been plagued by disruptions in the form of crude oil theft and pipeline vandalism which has had debilitating effects on its value.

Hierarchical Architecture for Enterprise Information System under Dynamic Environment

In a dynamic environment, it is vital for enterpris e to have flexible information system architecture to integrate ERP, Supply Chain Management (SCM) and E-Commerce (EC). The traditional systems are established o n the ERP-centered flat architecture. This architecture has some disadvantages in supporting the dynamics of enterprises. Firstly, ERP is already a very expens ive and complex system; the extension based on it can only increase the complexi ty and make the implementation more expensive and risky. Secondly, under the arc hitecture, the flexibility is reduced sharply although the execution efficiency is maintained. In a rapid changing environment, flexibility is also an equally i mportant factor besides execution efficiency. Thirdly, it cannot support the dyn amic collaboration efficiently. The prevailing of the flat architecture is not d ue to its advantage but to the big software providers. From the system viewpoint , a hierarchical architecture is proposed. Difference from the current architect ure, in the hierarchical paradigm, ERP is put in the bottom level rather centere d. SCM is the center system, which adopts a multi-agent structure. EC is regard ed as its foreground interface, while ERP and other information system of the pa rtner or internal units are the background executors. EC is the extension of mar ket agent and purchase agent. It fulfills the function of trade on Internet by s ending orders to be executed to SCM and receiving the progress information of th e orders from SCM. After receiving orders from EC, the agent in charge of schedu le in SCM makes preliminary plan in form of instructions (which may be infeasibl e) based on the information of source. Trough the coordination of multi agent, the plan is adjusted to be feasible. Compared with current ERP-centered flat ar chitecture, the hierarchical structure pays more attention to dynamic collaborat ion rather the optimization within the enterprise. At last, two engineering case s, Beijing Shang Pu Electric Ltd and Qingtao Tianyue International Building Mate rial Free Trade City, are presented to illustrate the idea.

INFORMATION SHARING AND STRATEGIC SIGNALING IN SUPPLY CHAINS

Information sharing in procurement occurs in rich and varied industry contexts in which managerial decisions are made and organizational strategy is formulated. We explore how information sharing ought to work in procurement contexts that involve investments in inter-organizational information systems （IOS） and collaborative planning, forecasting and replenishment （CPFR） practices. How and under what circumstances does a firm that plays the role of a supply chain buyer decide to share information on key variables, such as point-of-sale consumer demand data with its supplier, up the supply chain？ This is a key issue that crosses the boundary between supply chain management and information systems （IS） management. The answers that we provide are based on our use of a game-theoretic signaling model of buyer and supplier strategy in the presence of uncertainties about final consumer demand. We also explore the connection between operational costs that are associated with the firm＇s information sharing and information withholding strategies. Our results provide normative guidance to supply chain buyers about how to interpret different demand uncertainty scenarios to improve their decisions and generate high value. From the IS management perspective, we show the impacts on the firm of different information sharing approaches that are made possible by present day technologies.

The information technology barriers in supply chain of sugarcane in Khuzestan province,Iran:A combined ANP-DEMATEL approach

The present study aims at identifying and also prioritizing information technology barriers in supply chain of sugarcane in Khuzestan province.The statistical population of the study consisted of all senior managers of sugarcane industries in the province.Of four large rel-evant companies in the field,34 senior managers were selected.The required data was col-lected through two stages hiring questionnaires.In order to evaluate information technology barriers at the supply chain level,six main dimensions were considered includ-ing technological,supply chain management,strategic,organizational,individual and cus-tomer barriers.DEMATEL technique was also used to identify the relationship between indicators,and the ANP method was also employed to prioritize the before mentioned bar-riers.The results of DEMATEL showed that strategic barrier indicator acts as the most influ-ential,and the supply chain management barrier indicator as the most impotent one.The results of ANP method showed that of all research indicators,customer barrier indicator(weight 0.00127)was the most important indicator.Next,organizational and supply chain management barrier indicators are ranked second and third,respectively.Also,among the 28 research components(sub-criteria),the“lack of financial support”component with the weight of 0.04821 ranked first,followed by“poor outsourcing management”and“high investment and installation costs”as second and third respectively,which also had the most impact on the sugarcane supply chain.

The choices of channel structures and information strategies in a supply chain

This study considers the choices of channel structures and information strategies in a supply chain with demand uncertainty.The results show the following:(1)The decentralized channel structure dominates the centralized channel structure when the information strategy is given.(2)Information sharing by the downstream rival is always beneficial to the vertically integrated producer but is not necessarily detrimental to itself.In particular,information sharing increases the downstream rival’s profit in the centralized channel structure when the demand signal is relatively accurate.(3)The vertically integrated producer always benefits from the increase in forecast accuracy and the downstream rival may be worse off in some situations,which provides a theoretical ground for the“accuracy trap.”In addition,the discussions of the wholesale price commitment and the uniform pricing contracts show that the wholesale price contracts can influence the information sharing conditions of the downstream rival and the effects of strategic decentralization,eventually influencing the equilibrium strategies of channel members.
