TL;DR: The model based Decision Support System (DSS) is designed to help choose the best supplier for each item and schedule the placement of the orders—decisions which are very difficult to make well without such a model based DSS.
Abstract: This paper describes a model based Decision Support System (DSS) for purchasing materials and components for large projects. The DSS may be used under two scenarios. Under the first scenario, we have a project to execute, and we are looking for a good way to manage the purchasing to minimize the expected costs. The decisions under our control are when and from whom to order each item. Under the other scenario, we are bidding for the project, and wish to assess the costs associated with the purchasing decisions which we should consider before making our bid. In both cases, we take into account expected out of pocket costs as well as lateness and/or expediting penalties. The DSS is designed to help choose the best supplier for each item and schedule the placement of the orders—decisions which are very difficult to make well without such a model based DSS.

TL;DR: In this article, the problem of building optimally coordinated bidding strategies for competitive suppliers in day-ahead energy and spinning reserve markets is addressed, and two different bidding schemes have been suggested for each hour, and based on them an overall coordinated bidding strategy is then developed.

TL;DR: In this paper, the authors analyse regulation by contract in public-private partnerships (PPPs) for infrastructure services, showing that risks are not allocated correctly nor is effective monitoring ensured in the preparation of public tender documents; the "best" bidder is often not the winner.
Abstract: This paper analyses regulation by contract in public-private partnerships (PPPs) for infrastructure services. Although the benefits of competition for the market and subsequent regulatory contracts are recognised, the literature also identifies contract design failures. When considering these limitations, it is useful to distinguish between contracts associated with purely contractual PPPs (concessions) and contracts for institutionalised PPPs (mixed company). Two cases from the Portuguese water sector are used to illustrate problems arising in the preparation of public tender documents: the "best" bidder is often not the winner. Often, risks are not allocated correctly nor is effective monitoring ensured. Comparisons between the two types of contracts show how external regulation can be useful in mitigating contractual problems. This examination of bidding procedures and contract design yields several implications for policy-makers; in addition, the study presents recommendations for improving regulatory contracts.

TL;DR: In this paper, the authors review different kinds of corruption observed in procurement auctions and categorize them and discuss means to avoid corruption, by choice of preferable auction formats, or with the help of technological tools, such as secure electronic bidding systems.
Abstract: We review different kinds of corruption that have been observed in procurement auctions and categorize them. We discuss means to avoid corruption, by choice of preferable auction formats, or with the help of technological tools, such as secure electronic bidding systems. Auctions that involve some soft elements, such as complex bids consisting of technical and financial proposals, are particularly prone to corruption. We do not believe that it is possible to eradicate corruption altogether in such situations, but we discuss means to make it less likely.

03 May 2013TL;DR: In this paper, a coexistence management service for licensed and unlicensed spectrum sharing is provided for co-channel sharing, which includes a co-existence manager (CM) that may provide resource allocation services for a CE.
Abstract: Systems and methods are provided for coexistence management service for licensed and unlicensed spectrum sharing. A coexistence system may include a coexistence manager (CM) that may provide resource allocation services for a coexistence enabler (CE). CMs may negotiate with each other to resolve coexistence issues via directly or indirectly through a coexistence discovery and information server (CDIS). A channel may be exclusively used by a CE network. The networks may mitigate interference by avoiding use of the same channels. A channel may be shared by multiple CE networks. In co-channel sharing, the networks may mitigate interference via power management. Bidding processes may be implemented directly via competing CMs, for example via open or silent token auction. Bidding processes among competing CMs may be managed by a third party entity, for example a CDIS, for example via open or silent token auction.
