This study considers a multi-class network resource in a competitive market where each user endowed with an initial budget will purchase bandwidth from each class of the network resource to maximise its utility function. The authors use revenue as the utility function for the service provider, and enhance Kelly’s utility function by including delay as the quality of service (QoS) parameter for ...

Provision of Social Goods and Soft Budget Constraints* by Lars-Hendrik Röller and Zhentang Zhang Firms in socialist and transitional economies are often obliged to provide a social good in addition to a private good, which makes it difficult for a government to commit not to bail out the firm once it is in financial trouble. This creates a soft budget constraint syndrome which causes the firm t...

Firms frequently utilize multiple communications instruments as part of their marketing campaign. Interactions between these instruments suggest that firms should apply Integrated Marketing Communications (IMC) to benefit from the synergies. We review different IMC models and then present a stochastic IMC model for which explicit closed-loop solutions of the optimal advertising and market share...

The reform to convert non-floating shares to floating in China provides a setting in which shares are subject to different liquidity constraint. We show that the severity of this constraint is inversely related to the extent to which earnings information is reflected in the share prices. Specifically, before the reform, the transfer prices of non-floating shares reflect much less earnings infor...

Developing a product family under a robust platform provides a company with an important competitive advantage. The competitive benefits include reducing engineering costs and time to market, extending product portfolios and expanding market share. This study illustrated an algorithm based design methodology using two decision techniques for achieving optimal product architecture. The analytic ...

We study a continuous knapsack problem with separable convex utilities. We show that the problem is NP-hard, and provide two simple algorithms that have worst-case performance guarantees. We consider as an application a novel subsidy allocation problem in the presence of market competition, subject to a budget constraint and upper bounds on the amount allocated to each firm, where the objective...

Firefly algorithm (FA) is recently developed nature-inspired metaheuristic based on the flashing patterns and behaviour of fireflies. Original FA was successfully applied to solve unconstrained optimization problems. This paper presents firefly algorithm to solve constrained optimization problems. For constraint handling, firefly algorithm uses certain feasibility-based rules in order to guide ...

With rapidly growing network, Internet has turned into an essential wellspring of transmitting confidential or secret data, for example, military data, money related records, and so forth. In such cases, strategies committed to ensure such kind of information are needed and they play an imperative role in providing confidential and secure transmission over network. Visual cryptography scheme is...

Electronic Exchanges are double-sided marketplaces that allows multiple buyers to trade with multiple sellers, with aggregation of demand and supply across the bids to maximize the revenue in the market. In this paper, we propose a new design approach for an one-shot exchange that collects bids from buyers and sellers and clears the market at the end of the bidding period. The main principle of...
