The goal of this paper is to show how the concept of fuzzy logic can be used to establish a degree to which an investment project belongs to a class of risk. Also, the probability of the fuzzy event is presented and is ap-plied to calculate the probability of the fuzzy event “the project X is a good investment”. This process has to enable the decision maker to compare several alternative invest...

Nowadays, numerous processes of any supply chain are done by suppliers and consequently they cause a massive amount of pollution released to the nature. Hence, greening the suppliers has become a necessity. Although most of green supplier development programs need high investment, formal optimization models that address this issue are very rare. This paper mainly aims to address this prob...

This article examines the determinants of private investment in Brazil from sectorial industry data for the period of 1996 to 2010. The series of gross fixed capital formation, commonly used in empirical studies of aggregate investment, eliminates irregular adjustments of individual production units due to the aggregation process. Using the industry’s sectorial data it is possible to avoid smoo...

This paper studies optimal investment and the dynamic cost of income uncertainty, applying a stochastic programming approach. The motivation is given by a case study in Finnish agriculture. Investment decision is modelled as a Markov decision process, extended to account for risk. A numerical framework for studying the dynamic uncertainty cost is presented, modifying the classical expected valu...

• Since Wilkie’s result [9] (which established that the elementary theory Texp of (R, exp) is model complete and o-minimal), many o-minimal expansions of the reals have been investigated. The problem of constructing nonarchimedean models of Texp (and more generally, of an ominimal expansion of the reals) gained much interest. • In [2] it was shown that fields of generalized power series cannot ...

The Extraordinary Magnetoresistance (EMR) effect is a change in the resistance of a device upon the application of a magnetic field in hybrid structures, consisting of a semiconductor and a metal. The underlying principle of this phenomenon is a change of the current path in the hybrid structure upon application of a magnetic field, due to the Lorentz force. Specifically, the ratio of current, ...

While the majority of security practice — and spending — is focused on post-development products and enterprise approaches, some have sought to change the focus of security from the networks we manage to the systems we build. The burgeoning Secure Software Engineering (SSE) community has sought to identify and espouse activities, built upon traditional software engineering, that address the int...

The usual focus in authorship studies is on authorship attribution, i.e. determining which author (of a given set) wrote a piece of unknown provenance. The usual setting involves a small number of candidate authors, which means that the focus quickly revolves around a search for features that discriminate among the candidates. Whether the features that serve to discriminate among the authors ar...

In this paper we present a new approach for the planning of an investment project in the field of building construction. The focus is in shaping of the concept that serves to facilitate decision making about investments through providing support to investors’ when they are dealing with a problem selection of a solution for investment project. The concept is based on the combined use of several ...
