E-procurement solutions can deliver great cost-saving potential for purchasing. But services have not generally been considered as a part of these cost-saving measures. The process of service procurement is often argued to be more complex and less standardized than material procurement. In this paper we propose solutions and standards for service procurement.

This paper compares the performance of different sequential auction settings for the procurement of truckload services. In this environment, demands arrive randomly over time and are described by pick up, delivery locations and hard timewindows. Upon demand arrival, carriers compete for the loads. Different auction and information disclosure settings are studied. Learning methodologies are disc...

For a stable supply of electricity power plants are required to provide ancillary services in addition to energy production. This paper suggests a solution for optimal bidding strategy for hydroelectric units operating in markets where both energy and ancillary services are priced simultaneously. The model is illustrated on a numerical example of a hydro unit operating in such markets of New Yo...

With significantly increasing share of variable renewable power generation like wind and solar PV, the need in the power system for ancillary services supporting the network frequency, voltage, etc. changes. Turning this issue around, market opportunities will emerge for wind and solar PV technology to deliver such grid services. In the European power system, adequate market mechanisms need to ...

arbitrage is a known economic term, implying simultaneous transaction on commodities. for instance, a generation company (genco) may involve itself in selling fuel, emission allowance and etc., instead of generating either active or reactive power. moreover, arbitrage between active and reactive powers can, in turn, be considered. in this paper, arbitrage between active and reactive power is c...

Ancillary services constitute the cornerstone of the power grid. They allow for an efficient system operation, provide resilience to uncertainties and establish safeguards against unprecedented events. Their importance is growing due to the rise of grid decentralisation and integration of intermittent, renewable power sources, which lead to more variability and uncertainty in the system. Today,...

Centralized procurement is now the development trend of procurement management of large enterprise groups at home and abroad. State Grid Materials Co, Ltd has accumulated rich experience of providing agent services to many international tendering projects including those using the World Bank and the Asian Development Bank loans. It has developed a standardized centralized procurement procedure ...

The implementation of electronic procurement processes for product-service systems, consisting of material and service components requires a consideration of strategic, tactical and operational issues in procurement processes and information technologies. Increasingly, in certain industries, these product-service systems consist more and more of cloud-based components like online storage or web...

This paper examines the infusion of e-procurement applications along two dimensions of usage – intensity and organizational acceptance – and tests the relationship between use and procurement performance. Drawing upon the resource-based view of the firm, this paper tests the relationship between select organizational resources and e-procurement infusion in the context of procurement of indirect...

TPBOSCourier is the Transportation Procurement and Bid Optimization System (TPBOS) for Philips Electronics to automate and optimize its procurement of courier services. It was jointly developed by Red Jasper Limited and the Hong Kong University of Science and Technology, and has been successfully deployed in 2005. Philips typically procures courier services for more than 2500 shipping lanes ann...
