It consists of the following nine chapters. Chapter 1 describes a brief discussion on decision making problems in neutrosophic set environment. It presents some basic definitions and operations of neutrosophic sets, single valued neutrosophic sets, interval neutrosophic sets, bipolar neutrosophic sets and neutrosophic cubic sets. Chapter 2 proposes a new cross entropy measure in single-valued neutrosophic set environment, namely NS-cross entropy, and proves its basic properties. It also defines weighted NS-cross entropy measure and investigates its basic properties. It develops a novel MAGDM strategy that is free from the drawback of asymmetrical behavior and undefined phenomena. Chapter 3 proposes IN-cross entropy measure and proves its basic properties. It also develops weighted IN-cross entropy measure and investigates its basic properties. Based on the weighted IN-cross entropy measure, it develops a novel MAGDM strategy in interval neutrosophic environment. It solves an illustrative example of MAGDM to show the feasibility, validity and efficiency of the proposed MAGDM strategy. Chapter 4 proposes the score function and accuracy function for neutrosophic cubic sets and prove their basic properties. It also develops a strategy for ranking of neutrosophic cubic numbers based on the score function and accuracy function. In this chapter, it firstly develops a TODIM (Tomada de decisao interativa e multicritévio) in the neutrosophic cubic set (NC) environment, namely the NC-TODIM. It establishes a new NC-TODIM strategy for solving MAGDM in neutrosophic cubic set environment. It illustrates the proposed NC-TODIM strategy for solving an MAGDM problem to show the applicability and effectiveness of the developed strategy. It also conducts sensitivity analysis to show the xii impact of ranking order of the alternatives for different values of the attenuation factor of losses for the proposed MAGDM strategy. Chapter 5 defines similarity measure for neutrosophic cubic sets and proves some of its basic properties. It presents a new MAGDM strategy with linguistic variables in neutrosophic cubic set environment. Finally, it presents a numerical example to demonstrate the usefulness and applicability of the proposed strategy. Chapter 6 proposes VIKOR strategy in neutrosophic cubic set environment, namely NC-VIKOR. It first defines NC-VIKOR strategy in neutrosophic cubic set environment to handle MAGDM problems. Actually, it combines the VIKOR with neutrosophic cubic numbers to deal with MAGDM problems. Finally, it solves an MAGDM problem to show the feasibility, applicability and effectiveness of the proposed NC-VIKOR strategy. Further, it presents sensitivity analysis to show the impact of different values of the decision making mechanism coefficient on ranking order of the alternatives. Chapter 7 introduces a new cross entropy measure in a neutrosophic cubic set environment, namely, NC-cross entropy measure. It proves its basic properties. It also proposes weighted NC-cross entropy and investigates its basic properties. It develops a novel MADM strategy based on a weighted NC-cross entropy measure. To show the feasibility and applicability of the proposed MADM strategy, it solves an illustrative numerical example. Chapter 8 extends the VIKOR (VIsekriterijumska optimizacija i KOmpromisno Resenje) strategy to MAGDM with bipolar neutrosophic set environment. It first defines VIKOR strategy in bipolar neutrosophic set environment to handle MAGDM problems. It combines the VIKOR with bipolar neutrosophic numbers to deal with MAGDM. It solves an MAGDM problem in bipolar neutrosophic set environment. Further, it presents sensitivity analysis to show the impact of different values of the decision making mechanism coefficient on ranking order of the alternatives. Chapter 9 concludes the thesis with some future scope of research. Introduction Chapter 1 classify. There are:  MADM in exact environment/ crisp environment  MADM in uncertain environment neutrosophic set for MANETs data case study. Further, Elwahsh et al. (2018) proposed a novel approaches for classifying MANETs attacks with a neutrosophic intelligent system based on genetic algorithm. Salama et al. (2014) employed neutrosophic set to design and implement of neutrosophic data operations based on object oriented programming.

Dabei spielen Aporien, also Konflikte,die systemlogisch nicht aufgelost werden konnen, eine besondere Rolle. In diesem Artikel vertreten wir die Annahme,dass eine nachhaltige Entwicklung im Widerspruch zu derzeit praktizierten und als nicht nachhaltig eingestuften Entwicklungspfadensteht. Einige dieser Widerspruche weisen Merkmale aporetischer Konflikte auf. Gerade diese enthalten groseLern- und Gestaltungspotenziale, die in der universitaren Lehre vermittelt werden sollen. Im Rahmen einer fakultatsubergreifendenZusammenarbeit bietet die Alpen-Adria-Universitat in Klagenfurt ein Wahlfachmodul „Nachhaltige Entwicklung“an. Der Artikel illustriert am Beispiel nachhaltiger Regionalentwicklung aus diesem Lehrveranstaltungsmodul, welcheWiderspruche und aporetische Konflikte im Zusammenhang mit Transformationsprozessen zu erwarten bzw. festzustellensind.

The results show that consumers' want durable goods to last between 1.7 and 3.6 times longer than they are used. Moreover, we emphasise the difference between desired and expected lifetimes and explain, how the consumers' expectations regarding product lifetimes affect their buying and replacement decisions.
