TL;DR: Greenwood et al. as discussed by the authors investigated the impact of procurement routes on delivering energy-aware buildings, particularly in the case of environmentally sensitive buildings, where the necessary design iterations are at odds with the contractor's time and cost incentives.

TL;DR: A comprehensive review of traditional and emerging procurement practices in the construction industry can be found in this article, where the current procurement practices are analyzed by separating into three segments; processes, methods, and policies.
Abstract: Procurement is a key process in a construction project that creates and manages contacts. Procurement activities span from identification of requirements to project closeout, making it a perfect mode for integrating organizational strategic directions. Lately, the strategic importance of procurement has been widely acknowledged by academics as well as industry professionals. Construction procurement is a complex process with a large number of available options and directions. Ad hoc statistics show that modern initiatives such as sustainability, life-cycle costing, and standardization are getting integrated with procurement. However, there is no unified view in the construction industry on procurement as a project process. This paper presents a comprehensive review of traditional and emerging procurement practices in the construction industry. The current procurement practices are analyzed by separating into three segments; processes, methods, and policies. Furthermore, strengths and weaknesses of...

TL;DR: The dynamics and convergence to equilibrium of the interactions of a single buyer with a heterogeneous group of sellers are documented, which results in both separation of sellers capable of producing high-quality goods from those incapable of doing so, and continuing incentives for high- quality-capable sellers to produce at the maximum quality possible.
Abstract: We use agent-based modeling to study the performance of a supplier selection model, originally proposed by Croson and Jacobides [Small Numbers Outsourcing: Efficient Procurement Mechanisms in a Repeated Agency Model, Working Paper #99- 05-04 Department of Operations and Information Management, The Wharton School of the University of Pennsylvania (1999)], which displays a complicated reward and punishment profile under incomplete information. We document the dynamics and convergence to equilibrium of the interactions of a single buyer with a heterogeneous group of sellers, which results in both separation of sellers capable of producing high-quality goods from those incapable of doing so, and continuing incentives for high-quality-capable sellers to produce at the maximum quality possible. We model two methods of determining exploration reference points--an "auction-style" model focusing on probability of success and a "newsvendor-style" model focusing on profitability. Our simulation shows that (1) the tournament structure suffices to reach convergence at high-quality levels whenever the number of suppliers exceeds three, (2) punishment length and number of suppliers are substitutes, and (3) shorter punishments improve learning speed of convergence. Moreover, we show that it is strictly better for the buyer to transact with relatively few suppliers--a conclusion generated endogenously inside the model as a tradeoff between exploration and exploitation, rather than through assumptions that explicitly penalize supplier proliferation.

TL;DR: In this article, the authors consider what an accounting for sustainability of production and supply chains might look like, and provide an overview of the issues associated with a broadening of accounting needed for sustainable supply chains.
Abstract: Growing interest in sustainability and corporate supply chains accompanies increased globalisation across developed and developing countries, a stronger focus on the logistics of procurement behind international trade, and information flows between parties about corporate economic, social and environmental performance. Accounting provides information to oil the wheels of supply chain relationships. The purpose of this paper is to consider what an accounting for sustainability of production and supply chains might look like. An overview is provided of the issues associated with a broadening of accounting needed for sustainable supply chains. The paper highlights: ongoing problems of scope and terminology, lack of a broad sustainability focus because of complexity which stunts the impact on decision makers, and the need for transdisciplinary teams to increase connectedness and performance of the supply chain. The need for further research relating to three issues is identified. First, who undertakes the accounting for supply chains; second, why should a business function account for supply chain involvement; and, third, what information is relevant to different functional managers?
