American Options Based Service Pricing For Virtual Operators
2008
In the recent years, the role of service provider has split into two broad categories: Network Operators, offering services over their networks, and Virtual Operators, providing services over leased resources. What differentiates these players is to a minor extent a matter of enhanced service offer, and primarily a matter of economic objectives and risk attitudes. Essentially, Network Operators own their infrastructures and typically have to sustain both fixed costs (CAPEX) and recurrent costs (OPEX), while Virtual Operators may have a simpler cost structure, mainly consisting of OPEX for hiring the network. Correspondingly, the objectives of these players may differ profoundly: on one hand…
Parking Pricing for a Sustainable Transport System
2014
Abstract The purpose of this study has been the develop of a model for designing an efficient parking pricing policy. The aim is an intelligent control and management system of parking pricing integrated with a redefinition of the circulation scheme for a limited traffic zone in the Central Business District (CBD) of Palermo. The transport demand over the entire area of the town has been studied in order to design various parking pricing scenarios with the application of an additional cost on parking inside the selected area of the CBD. This area attracts most of the private vehicular traffic and it is characterized by university faculties, schools, hospitals, offices and commercial areas. …
Revenue-Aware Resource Allocation in the Future Multi-Service IP Networks
2006
In the future IP networks, a wide range of different service classes must be supported in a network node and different classes of customers will pay different prices for their used node resources based on their Service-Level-Agreements. In this paper, we link the resource allocation issue with pricing strategies and explore the problem of maximizing the revenue of service providers in a network node by optimally allocating a given amount of node resources among multiple service classes. Under the linear pricing strategy, the optimal resource allocation scheme is derived for the case that no firm Quality-of-Service (QoS) guarantees are required for all service classes, which can achieve the …
Should conference pricing mechanisms incorporate options?
2016
The provision of many services is often characterized by demand uncertainty, as, at the time of purchase, consumers may not be completely informed about their valuation for the service or the possibility to utilize the service when it will actually be provided. For such reason, service providers implement several pricing mechanisms to maximize their profits in presence of consumer uncertainty and heterogeneity. A commonly adopted mechanism is intertemporal price discrimination, under which service providers charge different prices to consumers buying at different times. For instance, a lower price is usually offered to consumer buying early in advance, whereas higher price is practiced to l…

Infrastructure, Tariff and Legal Action: How to Achieve a Climate-Friendly Transport System
2011
Transportation absorbs about 70% of oil consumption in EU countries. The fuels that burn in the field of transport are composed of 96% of oil. Energy efficiency of road and air traffic must also be improved. But transport environmental impacts reductions should be made necessarily through a transfer of traffic from the car, lorries and aircraft to train, ship, and non motorized two-wheelers into the EU cities. In fact the former are large producers of greenhouse gases, while the latter are more environmentally friendly means of transport in climate. Reaching an annual increase of 1% of the modal split in favour of more sustainable means of transport on the environment must be set as a goal …

TECNICHE QUANTITATIVE PER LA PROGETTAZIONE DELLA TARIFFAZIONE DELLA SOSTA IN AMBITO URBANO
Ad oggi numerose resistenze dibattono sull’adozione di schemi di pricing nei centri urbani dalla presunta iniquità, che renderebbero di fatto accessibili i centri urbani soltanto a coloro che possono permettersi di pagare la tariffa di accesso. Ma al contempo l’evoluzione di tecnologie innovative di rilevamento e di infomobilità consentono di ipotizzare un completo ribaltamento dei criteri di tassazione del traffico stradale, dove il carico fiscale potrebbe essere rimodulato in relazione agli effettivi comportamenti di ogni singolo utente. L’obiettivo è stato quello di controllare e limitare la mobilità all’interno di una determinata area urbana attraverso un nuovo modo di concepire le ZTL …
Demand Response Pricing Strategies for Islanded Microgrids
2013
In this paper, Time of Use and Critical Peak Pricing policies are designed and their effects on optimized operation is evaluated. For this purpose, an optimal operation algorithm is employed and the relevant production costs are derived. As far as the Time of Use policy is concerned, such costs are observed to be different in two time intervals of the day, due to the loads changing effect and the production of renewable energy. Whereas in the Critical Peak Pricing Policy, a peak time interval is identified to set up different pricing rates. The optimization algorithm used to carry out the work described above minimizes the microgrid's energy losses, the production costs and the Green House …
