TL;DR: In this paper, the benefits of combinatorial auctions from the carrier's perspective were examined from the perspective of a simple sealed-bid auction in which each bidder submits a sealed bid for a single item.
Abstract: The procurement of transportation services is an important task for shippers because of the need to control costs at the same time as providing high service levels. When shippers with goods and/or materials to transport seek transportation services from outside companies they typically put out a request for quotes from a set of carriers. They then assign contracts based on negotiated service charges. This process is similar to a simple sealed-bid auction in which each bidder submits a sealed bid for a single item. In the past, when shippers need to procure transportation services for a set of distinctive delivery routes (called lanes) they would obtain quotes for each lane individually and repeat the simple auction process for each lane. Alternatively, they might negotiate for bundles of lanes with a single carrier at a time. However, in the last few years software has been developed to allow shippers to make all lanes available for bidding simultaneously and to allow carriers to simultaneously bid upon combinations of individual lanes. This method of awarding contracts, conventionally called a combinatorial auction, has been reported to result in significant cost savings for shippers. Our research examines the benefits of combinatorial auctions primarily from the carrier's perspective. Preliminary findings, based on a simple simulation model suggest that benefits for carriers can also be significant.

TL;DR: In this article, the authors present a fully automated, requisition-driven, centralized e-procurement system, suitable for governments or entities with similar procurement needs, where a reverse-auction among competing authorized suppliers is employed for purchases of all goods and services.
Abstract: A fully automated, requisition-driven, “J.I.T.”-based, centralized e-procurement system, suitable for governments or entities with similar procurement needs. A Web site-based reverse-auction among competing authorized suppliers is employed for purchases of all goods and services, except those that must be procured by other means. Automated processes for: requisition handling and pooling; order formulation, processing and tracking; consolidated, distributed, and other shipping arrangements; procurement accounting and payment authorization; supplier-relations administration; centralized procurement catalog management; procurement data analysis and report and alert generation; procurement needs analysis; and inventory management are included. A structure of separate internal and external modules is created for security. To the extent possible, all communication from and to and within the system is preformed digitally.

TL;DR: In this paper, the authors examine a dynamic model of price competition in defense procurement that incorporates the experience curve, asymmetric cost information, and the availability of a higher cost alternative system, and characterize the class of production contracts that are cost minimizing for the government and that induce the developer to reveal private cost information.
Abstract: We examine a dynamic model ofprice competition in defense procurement that incorporates the experience curve, asymmetric cost information, and the availability of a higher cost alternative system. We model acquisition as a two-stage process in which initial production is governed by a contract between the government and the developer. Competition is then introduced by an auction in which a second source bids against the developer for remaining production. We characterize the class of production contracts that are cost minimizing for the government and that induce the developer to reveal private cost information. When high costs are revealed, these contracts result in a credible cutoff of new system production in favor of the still higher cost alternative system.

TL;DR: In this paper, the authors apply the theory of Swift, Even Flow to illustrate the potential impact that both the Product and Process of ERP implementation can have on overall operational effectiveness, and suggest the impact that such improved effectiveness might have on the ability of a firm to take advantage of B2B e-procurement technologies.
Abstract: Although a considerable amount of documentation has been published on the alleged benefits of Enterprise Resource Planning (ERP) systems, rigorous theoretically supported research into this topic has been limited. Furthermore, with the recent popularity of new technologies such as those supporting Business-to-Business (B2B) e-procurement, many have begun to loose focus of the underlying infrastructure upon which these new technologies depend, and which ERP systems provide. The aim of this paper is to provide a theoretical foundation for the consideration of the criticality of ERP system implementations with regards to the effective utilization of up-and-coming technologies. We approach this task in two steps. First we apply the theory of Swift, Even Flow to illustrate the potential impact that both the Product and Process of ERP implementation can have on overall operational effectiveness. We then utilize the theory of Resource Dependency to suggest the impact that such improved effectiveness might have on the ability of a firm to take advantage of B2B e-procurement technologies. An investigation of 61 B2B success cases reveals that the extent to which firms witness savings through such procurement is dependent not only on the presence of an implemented ERP system but also on the length of time such systems have been present and active.

TL;DR: In this paper, the authors identified the critical factors impacting on the development of purchasing groups and the importance and the nature of these factors change, depending on the developing phase of the purchasing group, as illustrated by the application that they have made of these features to the American healthcare sector.
