We investigate the Cauchy problem for an ordinary differential (ODE). We propose two new schemes that compute an approximate solution. Both of them are based on the technique of the second degree F-transform. The quality of new schemes is compared with the exact solution and the Euler method.

This is a monograph written for the young and advanced researcher who is entering the field of wet granular matter and keen to understand the basic physical principles governing this state of soft matter. It treats wet granulates as an instance of a ternary system, consisting of the grains, a primary, and a secondary fluid. After addressing wetting phenomena in general and outlining the basic facts on dry granular systems, a chapter on basic mechanisms and their effects is dedicated to every region of the ternary phase diagram. Effects of grain shape and roughness are considered as well. Rather than addressing engineering aspects such as existing books on this topic do, the book aims to provide a generalized framework suitable for those who want to understand these systems on a more fundamental basis.

This book analyzes some of the most recent advances in the field of decision making and fuzzy systems applied to business and economics presented at the International Conference on Modeling and Simulation (MS''12 Rio de Janeiro), 10-13 December, 2012. In this conference, a special focus is given to the fundamental concept of sustainable development. Other key applications in business, economics and finance are also *** general, it is very useful for graduate students and researchers interested in pursuing research that combines quantitative techniques such as modeling and simulation and decision making with business and economic problems. This is especially useful when dealing with complex environments where the information is very uncertain and additional mathematical and statistical techniques are needed in order to understand the specific situations considered.

Using a single chart to monitor simultaneously the process mean and variability if found would cut down the time and effort. Some researches have been done in finding such charts. Moreover, some researches have showed that the adaptive control charts could detect process shifts faster than the traditional Shewhart charts. A much easier loss chart with variable design parameters is proposed here to monitor both the deviation from the process target and the shift in process variability. Furthermore, a more efficient optimal variable design parameters loss chart is proposed and performs better than the loss chart with fixed design parameters and the joint (X) over bar and S charts.

We propose a new image reconstruction technique which uses approximation properties of the fuzzy (F-)transform and its ability to remove noise. The proposed technique is based on the inverse F-transform and on a fusion which combines the inverse F-transform with the original image on a non-damaged area. We claim the new technique has less computation complexity than the usually applied technique of interpolation.

Collaborative product development (CPD) can be defined as two or more firms joining resources for the same goal, where the first phase is the partner evaluation process. The choice of partner affects the performance of the whole CPD, and therefore it must be conducted carefully. This paper presents criteria set defined specifically for CPD partner evaluation and proposes an integrated fuzzy multi-criteria decision methodology for the selection of the right partner. The technique enables decision makers to evaluate criteria weights and the potential partners separately.

In this paper, we turn our attention to model theory of higher-order fuzzy logic (fuzzy type theory). This theory generalizes model theory of predicate logic but has some interesting specificities. We will introduce few basic concepts related to homomorphism, isomorphism, submodel, etc. and show some properties of them.

One of the most important problems of project management is the decision of task durations in the projects. The duration of each task and cumulative durations of the successive tasks generally results in the success or fail of that project. While the common practice is to use natural numbers for task duration, they generally fail to match the real world results. In order to obtain more realistic results, researchers used fuzzy numbers which resulted in an important improvement of estimations but with the vagueness and uncertainty of the business world, they still require improvement. In our study, we used fuzzy numbers with AHP to determine task durations and adapt them to real world, first we separately find the levels of vagueness and uncertainty of tasks using AHP and then we use these categories to manipulate our fuzzy membership function for better prediction of tasks' durations and certainty levels so we can provide a more accurate project plan with more realistic task durations.

Filters play a significant role in studying of structure and properties of partially ordered algebraic structures, in particular in the algebraic semantics of formal fuzzy logics and, moreover, it is also very important for the proof of the completeness of these logics. The aim of this paper is to introduce a kind of quasi-filters in lattice implication algebras, which are the algebraic abstractions of the sets of provable formulae and are closed with respect to lifting rules (These rules were defined by Pavelka in Zeitschr. f. math. Logik und Grundlagen d. Math. 25: 447-464, 1979) in the corresponding formal fuzzy logic, and we examine their mutual dependencies and the connections with other different kinds of filters in lattice implication algebras.

The nurse scheduling problems (NSP) deal with assignment of the nurse to the specific shifts in specific days is taking into account both the hospital's need and nurse preference. In the hospitals, nurses are serving under difficult circumstances. To improve the quality of service, work schedules should be prepared in a fair manner and has to provide the desired conditions. In this study, it is aimed at developing a model which can be used in real applications and can be rapidly reached to the solution for the nurse scheduling problem. For this purpose, the formulated problem was solved by using artificial bee colony (ABC) algorithm, which is one of the new meta-heuristic methods. It has been coded a program with a user interface using the Visual Studio programming language for running the model. The designed interface is able to take into account the different level of the demand and the number of staff. The model was tested on a real problem and found better solution than the current situation.
