Determination of an Optimal Plan for Supplying an Infantry Battalion in Combat Conditions

Under current conditions the commander can not only rely on experience and intuition, so it needs an information-based analytical thinking and reasoning. In this context, the operational research, with its methods and models, represents the scientific basis on which a rational and optimal decision is supported, by involving a minimal risk. This paper presents the optimization of military action, showing how to solve a practical problem using the transportation problem. The paper combines mathematical methods for solving the problem of transport with the requirements imposed by the tactical situations parameters encountered in the course of military operations by exemplifying a complex military operation.

Tracking Economic Growth: A Correlation Analyse on the Determinants of Gross Domestic Product

Gross Domestic Product (GDP) is the most important measure of economic activity in a country. It ... more Gross Domestic Product (GDP) is the most important measure of economic activity in a country. It represents the total value of all goods and services produced in a particular country in a given period. GDP can be calculated using three methods, namely, the production approach, the income approach, and the expenditure approach. In this paper, we will focus on the Expenditure Method. The Expenditure Method of calculating GDP involves adding up the total value of all final goods and services purchased by the four groups of spending agents: households, firms, government, and foreign buyers. The purpose of this paper is to discuss how the components of GDP using the Expenditure Method influence GDP. Specifically, we will explore the relationship between each component of GDP and GDP as a whole, considering also the impact that inflation has on the real growth of the economic activity, and which is the real trend of this macroeconomic result indicator.

Some Classes of Surfaces Generated by Blending Interpolation on a Triangle with One Curved Side

Remind that blending interpolation is to interpolate a function at an infinite set of points: segments, curves, surfaces, etc. Thus, if one gives the contour of an object by such elements (segments, curves, surfaces) using a blending interpolation, we can generate a surface that contains the given contour. Hence, we can construct a surface (a blending function interpolant) which matches a given function and certain on its derivatives on the boundary of a plane domain (rectangle, triangle, etc. The aim of this paper is to construct some surfaces which satisfy some given condition on the boundary of a domain that can be decomposed in triangles with one curved side. We construct some new surfaces using some Lagrange, Hermite, Birkhoff and Nielson type operators.

It deals with the situation in which a commodity from several sources is shipped to different destinations with the main objective to minimize the total shipping cost. There are three well-known methods namely, North West Corner Method Least Cost Method, Vogel’s Approximation Method to find the initial basic feasible solution of a transportation problem. In this paper, we present some statistical methods for finding the initial basic feasible solution. We use three statistical tools: arithmetic and harmonic mean and median. We present numerical examples, and we compare these results with other classical methods.

We also consider some of their product and boolean sum operators. We study the interpolation properties and the degree of exactness of the constructed operators.
