We propose an architecture called InterPay for managing nancial interactions with for-pay digital library services. The approach accommodates multiple payment mechanisms, interaction models, and charging policies. Key components of our model are payment agents and payment capabilities that encapsulate payment policy and the details of payment on behalf of the user. Collection agents and collect...

the concept of business model has attracted increasing attention in recent years. specifically, growing number of internet providers on mobile phones are challenged by the selection of appropriate business model. considering the importance of a good business model in the firm’s success, this research investigates the business models selection process of internet providers on mobile phones in ir...

In this paper, we propose an Internet payment system which uses a payment gateway to handle the credit card payment transaction between customers, merchants and banks. To test and evaluate the payment system, we build an online travel agency called E-Travel, which simulates a real-life E-Payment application. On-line travel services including flight reservation, selling of travel accessories, to...

Mobile payment refers to the use of mobile devices to conduct payment transactions. Users can use mobile devices for remote and proximity payments; moreover, they can purchase digital contents and physical goods and services. It offers an alternative payment method for consumers. However, there are relative low adoption rates in this payment method. This research aims to identify and explore ke...

The recent nancial crisis demonstrates that an upstream member in a supply chain usually has a weaker cash liquidity. Cash shortage a ects material supply to a downstream member, which, in turn, a ects the performance of the entire chain. This paper provides a supply chain model that integrates material and cash ows and investigates the impact of payment policies on the system performance. Spec...

This study examines the capital-constrained payment scheduling problem related to software projects. An optimization model for the payment schedules of software projects is constructed from the joint perspective of the client and the contractor in software outsourcing projects. Then, a heuristic simulated annealing algorithm is designed to solve the model. Finally, a case study is presented to ...

We develop an inventory model to determine optimal ordering policy under permissible delay in payment by considering demand rate to be stock dependent. Mathematical models are derived under two different cases: credit period being greater than or equal to cycle time for settling the account, and credit period being less than or equal to cycle time for settling the account. The results are illus...
