This paper describes a methodology for the case mix problem in the health care sector. Aiming at maximizing the overall financial contribution of the given resource capacity within a hospital, the case mix problem is formulated as an integer linear programming model to produce the optimal...

In a restructured electricity market environment, the competition in the production and consumption of electric energy leads to the transmission network operating at or beyond one or more transfer limits. In such a situation, the system gets congested, resulting in an increase in the cost of...

This paper proposes a new On-Demand Ant-based Multiagent Routing Algorithm (ODAMRA) for Mobile Ad hoc Networks (MANETs), which combines the on-demand routing capability of Ad hoc On-demand Distance Vector (AODV) routing protocol with some modifications in the existing ant colony optimization...

A new 3-dimensional interpolation method is introduced in this paper. Corresponding to the method a novel interpolation operator has been constructed and used to obtain results. The main objective is to develop a mechanical way of interpolation that does not require very high degree of knowledge...

The simplest modification to overcome the widely known shortcomings of classical Newton's method is fixed Newton's method. However, the numerical convergence of fixed Newton's method is too slow, which results in high consumption of CPU time and large number of iterations as the system's...

We develop a multiple-stage algorithm for detecting outliers in Ultra High-Frequency financial market data. We show that an efficient data filter needs to address four effects: the minimum tick size, the price level, the volatility of prices and the distribution of returns. We argue that...
