This is a survey of the Steiner tree problem with profits, a variation of the classical Steiner problem where, besides the costs associated with edges, there are also revenues associated with vertices. The relationships between these costs and revenues are taken into consideration when deciding which vertices should be spanned by the solution tree. The survey contains a classification of the pr...

T salesman problems with profits (TSPs with profits) are a generalization of the traveling salesman problem (TSP), where it is not necessary to visit all vertices. A profit is associated with each vertex. The overall goal is the simultaneous optimization of the collected profit and the travel costs. These two optimization criteria appear either in the objective function or as a constraint. In t...

The paper studies the impact of bank specific, industry specific and macroeconomic factors affecting profitability of Indian Banks in a dynamic model framework. The persistence of bank profits and endogeneity of the factors have been accounted for using Generalised Method of Moments (GMM) as suggested in Arellano & Bond, 1991.The panel data for the study have been obtained from 42 Indian Schedu...

We examine the evolving structure of the US hospital industry since 1970, focusing on how ownership form influences entry and exit behavior. We develop theoretical predictions based on the model of Lakdawalla and Philipson, in which for-profit and not-for-profit hospitals differ regarding their objectives and costs of capital. The model predicts for-profits would be quicker to enter and exit th...

In this paper we employ an agent-based industry simulation model to study the effects of the interplay between individual firms’ market evaluation strategies on the extent of product innovations and overall industry development. In particular, we show that a homogenous industry consisting of companies with focus on historical profits yields high overall industry profits but is very unstable. Th...

A closed-loop supply chain recovery model with single manufacturer, single retailer and two competitive third-party recyclers is established with the application of game theory. This paper focuses on analyzing the optimal pricing decisions and profits of all the enterprises members in the decentralized structure. Through the analysis of model, the result shows that the manufacturer’s transfer p...

Within the current Internet, autonomous ISPs implement bilateral agreements, with each ISP establishing agreements that suit its own local objective to maximize its profit. Peering agreements based on local views and bilateral settlements, while expedient, encourage selfish routing strategies and discriminatory interconnections. From a more global perspective, such settlements reduce aggregate ...
