Fuzzy equivalents of all the classical capital budgeting (investment choice) methods are generalised or proposed. These equivalents can be used to evaluate and compare projects in which the cash ows, duration time and required rate of return (cost of capital) are given imprecisely, in the form of a fuzzy number. c © 2000 Elsevier Science B.V.

In this paper, we consider the robust optimal portfolio selection problem where the return mean and covariance are supposed to be uncertain comparing to Markowitz’s model. The return mean is uncertain changing in intervals, and we introduce the cuts of fuzzy number to build the uncertain intervals for covariance. We report on empirical tests in which we compare the robust model with the classic...

In this paper, we introduce the notion of Pythagorean Anti fuzzy graph. We then define Cartesian product and Lexicographic on It is proved that two graphs graph general, lexicographic regular need not be Necessary sufficient conditions for to are determined. Further, concept isomorphism with suitable example.

The government organizations grant incentives to promote green product consumption, improve green product quality, boost remanufacturing activities, etc. through various policies. The objective of this study is to highlight pros and cons of two incentive policies, namely (1) incentive on manufacturer’s R&D investment and (2) direct incentive to consumer based on greening level of the product on...

The problem of portfolio selection in investment concerns with minimizing the risk for a prespecified level of return. In this paper, the constraint on the level of return is fuzzified and the technique of fuzzy evolutionary programming is employed to select an optimal portfolio of securities with low risk and with highly acceptable level of total return. Experimental results show the method is...

Abstract At present, the entire globe gets engaged in importing and exporting products for promoting their business which supply chain management is playing a vital role. The main aspect of any effective transportation cargoes. To avoid damages cargoes during minimizing cost, returnable containers are used. present research deals with an inventory model Non-Vessel Operating Common Carrier (NVOC...

in this paper, a new method is proposed to find the fuzzy optimal solution of fully fuzzy linear bilevel programming (fflblp) problems by representing all the parameters as triangular fuzzy numbers. in the proposed method, the given fflblp problem is decomposed into three crisp linear programming (clp) problems with bounded variables constraints, the three clp problems are solved separately and...
