The interplay between two-dimensional percolation growth models and one-dimensional particle processes has been a fruitful source of interesting mathematical phenomena. In this paper we develop a connection between the construction of Busemann functions in the Hammersley last-passage percolation model with i.i.d. random weights, and the existence, ergodicity and uniqueness of equilibrium (or ti...

revenue management is the process of accepting or ordering which increases gained revenue by using different techniques of pricing and selling capacity. this technique has improved greatly in service sector specially passenger section. in this article, the process of selling ticket in tehran-mashhad route for ghazal passenger train is modeled by two methods: static multi class and heuristic ems...

Sports leagues constitute one of the few examples of legally operating cartels. In this paper I examine how gate revenue sharing may serve to coordinate talent investments within these cartels. I show that sharing revenues has the potential to raise cartel profits, because it decreases the incentive to invest in playing talent. Leagues consisting of teams with heterogeneous local markets should...

INTRODUCTION The balance between revenue and cost of an organization/system is essential to maintain its survival and quality of services. Emergency departments (ED) are one of the most important parts of health care delivery system. Financial discipline of EDs, by increasing the efficiency and profitability, can directly affect the quality of care and subsequently patient satisfaction. Accordi...

We study the simultaneous optimization of efficiency and revenue in pay-per-click keyword auctions in a Bayesian setting. Our main result is that the efficient keyword auction yields near-optimal revenue even under modest competition. In the process, we build on classical results in auction theory to prove that increasing the number of bidders by the number of slots outweighs the benefit of emp...

In a two-stage supply chain composed of a supplier and a retailer, the supply chain models under a fuzzy environment are researched. The parameters of market demand function, the costs of the supplier and retailer are treated as trapezoidal fuzzy numbers. The decision processes are analyzed under the decentralized and centralized decision, and the decision model with revenue sharing contract is...

This paper discusses the influence of time inconsistency problem on technology-leading firms' choice between in-house production and technology transfer. Because of incredibility of innovator's commitment of not exporting after licensing, she may not be able to extract rent from licensing as much as when she could commit credibly. Facing this distortion, she chooses in-house production when the...

Recent advances in battery energy storage technologies enable increasing number of photovoltaic-battery energy storage systems (PV-BESS) to be deployed and connected with current power grids. The reliable and efficient utilization of BESS imposes an obvious technical challenge which needs to be urgently addressed. In this paper, the optimal operation of PV-BESS based power plant is investigated...

I ncreased expenditures and the government size is an important issue in public sector economics. In this regard, various theories have been developed in order to justify the reasons for the public expenditure growth, and the theories have been empirically tested. One of the outlooks explaining the government expenditures growth and the economy size, is fiscal illusion approach. According ...
