政府采购招标快报

政府采购小常识四措施应对信息不对称在政府采购中存在着一系列的信息不对称,如政府采购部门对供应商了解有限,供应商对政府采购信息的认识也并不充分,以及政府采购部门内部信息不共享等。如何降低或消除这些信息不对称对政府采购的影响呢?笔者认为应从以下四个方面着手:首先要严格“供应商准入”制度,加大对供应商的资格审查力度。可以对参加政府采购活动的企业或供应商提出一定的要求,对供应商的财务、资金技术、内部管理等各个方面进行结合评定,符合的供应商才能参与政府采购活动。这样在一定程度上减少了由于采购部门对供应商的信息不对…

A knowledge-based supplier intelligence retrieval system for outsource manufacturing

Knowledge management is to promote business success through a formal, structured initiative to improve the use of knowledge in an organization, in which an effective organizational memory information system plays an increasingly important role. Unlike the past, the performance of an enterprise now depends much on the performance and relationship of its customer–suppliers in the value chain. Good customer–supplier relationships are important for an organization to respond to dynamic and unpredictable changes. This paper describes a knowledge-based supplier selection and evaluation system, which is a case-based reasoning decision support system for outsourcing operations at Honeywell Consumer Products (Hong Kong) Limited in China. As a result, collaborative suppliers are identified quickly during the new product development process. By using the system, the cumulative performance of suppliers is constantly updated automatically according to past practice. This means that the knowledge of suppliers can be retained, categorized, retrieved and managed effectively.

IntelliBid: An Event-Trigger-Rule-Based Auction System over the Internet

This paper presents the design and implementation of an Event-Trigger-Rule-Based auction system called IntelliBid. A network of Knowledge Web Servers, each consisting of a Web server, an Event-Trigger-Rule (ETR) Server, an Event Engine, a Knowledge Profile Manager, and Bid Servers and their proxies constitutes IntelliBid. Together, they provide auction-related services to the creator of an auction site and the bidders and suppliers of products. IntelliBid offers a number of desirable features. First and foremost is the flexibility offered to bidders for defining their own rules to control their bids in an automatic bidding process, which frees the bidders from having to be on-line to place bids. By using different rules, the bidders can apply different bidding strategies. Second, it furnishes valuable statistical information about past auctions to both suppliers (or sellers) and bidders. The information can assist a bidder in bidding and a seller in setting a reasonable base price and/or the minimum incremental price. Third, since rules that control the automatic bidding are installed and processed by the ETR servers installed at bidders' individual sites, bidders' privacy and security are safeguarded. The statistical information that is released by IntelliBid only depicts the trend of the bidding prices of a product. The information about bidders is kept completely secret, thus safeguarding the privacy of the bidders. Fourth, IntelliBid's event, event filtering and event notification mechanisms keep both bidders and suppliers timely informed of auction events so that they or their software system can take the proper actions in the auction process. Fifth, any registered user of IntelliBid, bidder or supplier, can monitor the bids placed to any product being auctioned in IntelliBid. Sixth, IntelliBid allows bidders to do both on-line (or manual) bidding and automatic bidding. It also allows a bidder to participate in several auctions at the same time, in both manual and automated modes. The bidding of a product can depend on the result of the bidding of another product. Last, but not least, IntelliBid allows a person or organization to play both the role of bidder and the role of supplier simultaneously. The Profile Manager keeps the information as a bidder and information as a supplier separately. Moreover, IntelliBid's architecture uses a parallel event management system to do event registration and notification. This paper also reports the result of a performance study on the implication of using such a parallel system to achieve scalability.

An intelligent supplier management tool for benchmarking suppliers in outsource manufacturing

A global corporation's supply chain usually consists of enterprises and manufacturers that are graphically dispersed around the world, whereby each company is involved in a wide variety of supply chain activities such as order fulfillment, international procurement, acquisition of information technology, manufacturing, and customer service. However, selecting suppliers based on accumulated experience is not both effective and scientific due to subjective judgment and lack of systematic analysis. Therefore, continuously tracking and benchmarking performance of suppliers and forming an appropriate supplier selection mechanism is one of the crucial activities in supply chain management. This paper presents an intelligent supplier management tool (ISMT) using the case-based reasoning (CBR) and neural network (NN) techniques to select and benchmark suppliers. The development of ISMT and how the CBR and NN techniques are used in benchmarking suppliers during the process of new product development in Honeywell Consumer Products (Hong Kong) Limited are presented.

Applying 2-Tuple Multigranularity Linguistic Variables to Determine the Supply Performance in Dynamic Environment Based on Product-Oriented Strategy

Supply performance assessment is not only the core mechanism for supplier management, but also the major task for enterprises in implementing supply chain management. Consequently, supply chain system implementation should rely on the results of supply performance assessments to supervise suppliers. However, supply performance assessment is always concerned with numerous supply behaviors, and the information obtained from these supply behaviors often varies during the measurement timeframe. Because of uncertainty and inaccuracy, the numerical data are not appropriate for demonstrating dynamic information. This study employs 2-tuple multigranularity linguistic variables to deal with dynamic information appropriately and assess supply performance, and even permits decision makers to introduce different linguistic terms (linguistic scale) based on consideration of supply behavior characteristics. The 2-tuple multigranularity linguistic variables present the information via linguistic and numeric results, both where the linguistic result could express the variation of dynamic information appropriately, and where the numerical result could further reflect the difference based on the same linguistic result to improve the sensitivity. Additionally, this study also employs a fuzzy linguistic quantifier to simulate the decision criteria based on the product strategy to further obtain the modified linguistic ordered weighted averaging operator with maximum entropy that will be exercised to aggregate the 2-tuple linguistic information. This investigation provides decision makers with rapid access to complete, and integrated information on the practical supply performance of suppliers as appropriate.     

A multi-agent based system for e-procurement exception management

E-procurement has become an important function of enterprise information systems. The process of e-procurement includes the automatic definition of product requirements, search and selection for suppliers, negotiation and contracting with suppliers. However, the adoption of e-procurement encounters various uncertainties from internal and external environments, such as inventory failure, sharp increased demand, and delivery delay. In this paper, we propose a novel agent-based architecture for an e-procurement system in which agent technology is applied to deal with the internal and external uncertainties. Through the collaboration and interaction between different agents, the architecture that we propose can enhance the flexibility to handle unexpected exceptions, thus leading to agile procurement management. To valid the feasibility of our approach, a case study has been conducted to investigate how our agents collaborate to manage the inventory failure exception which occurs in restaurant e-procurement.
