Public agencies rely on two key modes to procure goods and services: auctions and direct negotiations. The relative advantages of these two modes are still imperfectly understood. This paper therefore studies public procurement of regional passenger railway services in Germany, where regional agencies can use auctions and negotiations to procure regional passenger rail services. This offers the...

Nowadays, as the Internet services increase faster than ever before, government systems are reinvented as E-government services. Therefore, government procurement sectors have to face challenges brought by the explosion of service information. This paper presents a novel method for E-government procurement (eGP) to search for the optimal procurement scheme (OPS). Item-based collaborative filter...

In this paper, the problems of market monitoring and control of ancillary services of future energy systems are presented. We envision that future system operation of electric power systems will evolve into completely unbundled ancillary service markets that are governed by spot price signals. The grid operators need to acquire ancillary services through competitive markets for control of the s...

In a power system, having a high level of renewable energy penetration requires a large amount of ancillary services to balance the supply and demand in real time. Commercial buildings have significant thermal capacity and so offer large potential for providing such services. Recent research has shown that the power consumption of the Heating, Ventilation, and Air Conditioning (HVAC) system can...

The implementation of recommender systems in electronic procurement processes for service packages, consisting of productand service components requires a consideration of strategic, tactical and operational procurement as well as information and communication technologies in value networks. Increasingly, the design of recommender systems for procurement processes in value networks is of scient...

The implementation of electronic procurement processes for product-service bundles, consisting of productand service components requires a consideration of strategic, tactical and operational procurement and information and communication technologies in value networks. In the past, the scientific discussion oriented on traditional procurement processes for products and technology-solutions. Inc...

This paper describes a case study focused on redesigning procurement processes for research grants management at the U.S. Office of Naval Research. These processes focus on the procurement of R&D services, and how they can be redesigned and supported using Web-based capabilities. Through the application of empirical results and theoretical concepts from business process reengineering, electroni...

This paper discusses various market design options for procuring, pricing and settling Ancillary Services via competitive auctions by an Independent System Operator (ISO). The paper also discusses problems and potential solutions associated with these market design options based on actual experience of operating ISOs. These problems include price volatility and spikes and price reversals for th...
