TL;DR: This paper primarily considers B2B transactions in a reverse auction, that is, a procurement setting, and discusses the role that OR has played and undoubtedly will play in the design and implementation of multiple issue e-auctions.

TL;DR: A two-equation recursive regression model was used to analyse 48 contracts for IT support and maintenance and did not reveal any quantitatively significant price–performance trade-off, but did suggest that first-term contracts were more expensive than repeat contracts.
Abstract: The rapidly increasing use of outsourcing for IT services, both in the public and private sectors, has attracted much interest from researchers and practitioners alike. While early studies of IT outsourcing were largely qualitative in nature, more recent studies have attempted to analyse the outcomes achieved in quantitative terms. This paper is consistent with the latter, but goes further by modelling the price, performance and contract characteristics that are relevant to IT outsourcing. A two-equation recursive regression model was used to analyse 48 contracts for IT support and maintenance. The results did not reveal any quantitatively significant price–performance trade-off, but did suggest that first-term contracts (i.e. the first ever contract awarded by a client for the provision of a particular IT service) were more expensive than repeat contracts. Although competitive tendering did not result in lower prices than directly negotiated contracts, it was associated with comparatively better performa...

TL;DR: The Renewable Energy Independent Power Producers Procurement Programme (the REI4P) is an extensive initiative to install 17.8 GW of electricity generation capacity from renewables over the period 2012-2030.
Abstract: South Africa׳s Renewable Energy Independent Power Producers Procurement Programme (the REI4P) is an extensive initiative to install 17.8 GW of electricity generation capacity from renewables – wind, solar, biomass, biogas and hydropower – over the period 2012–2030. Although at the outset the REI4P seemed an expensive option, designed only to deflect criticism of South Africa׳s high carbon footprint and excessive dependence on coal-based electricity generation, the escalating costs of the latter, the rapidly falling costs of photovoltaic and wind power, and the increasingly competitive bidding process of the REI4P have changed this prospect. At the conclusion of round three, the weighted cost of energy has reached a 23% discount to the cost of new coal-based generation and a 28% discount to global renewable energy prices. The bidders׳ commitments to local employment creation have similarly increased from 11 to 18 jobs/MW. The programme is now well placed to deliver on a broad range of objectives, including regional development and black economic empowerment. However, maximum benefit from the REI4P will not be secured without some revision to aspects of the bidding and procurement process. More specifically, the local content provisions need to be tightened to drive higher levels of local manufacturing.

TL;DR: In this paper, a system and methods are disclosed for determining, through vehicle-to-vehicle communication, whether vehicles are involved in autonomous droning, and aspects of the disclosure related to determining ruminative rewards and/or aspects of vehicle insurance procurement/underwriting.
Abstract: System and methods are disclosed for determining, through vehicle-to-vehicle communication, whether vehicles are involved in autonomous droning. Vehicle driving data and other information may be used to calculate a autonomous droning reward amount. In addition, vehicle involved in a drafting relationship in addition to, or apart from, an autonomous droning relationship may be financially rewarded. Moreover, aspects of the disclosure related to determining ruminative rewards and/or aspects of vehicle insurance procurement/underwriting.

TL;DR: In this article, the authors consider simultaneous pricing and procurement decisions associated with a one-period pure inventory model under deterministic or probabilistic demand and investigate the necessary and sufficient conditions for an (σ, Σ) type policy to be optimal for the determination of the procurement quantity.
