The paper addressed on solving a very important issue concerning environmental lease for implementing ecotourism business. The study answered following questions: (i) How are competitive advantages of environmental lease locations? (ii) How much is the price of environmental lease for ecotourism business? And (iii) Which group of environmental lease locations can be formed? Two main methods were applied in the study including willingness to pay (WTP) and fuzzy regression (FR).

This article is based on published works on fuzzy control for robots in general and mechanical processing robots to analyze the applicability of fuzzy control for mechanical machining robots. The article provides detailed information on fuzzy controller design, determining input and output variables, and proportional mapping to determine the number of fuzzy sets and the corresponding type of membership function.

The intent of this book is to describe some recent data mining tools that have proven effective in dealing with data sets which often involve uncertain description or other complexities that cause difficulty for the conventional approaches of logistic regression, neural network models, and decision trees. We have organized the material into three parts. Part I introduces concepts. Part II contains chapters on a number of different techniques often used in data mining. Part III focuses on business applications of data mining.

In this paper, we build an incremental algorithm to find the approximate reduct according to the combined filter-wrapper approach. Experimental results on a number of sample datasets show that the proposed incremental algorithm is more efficient than some other incremental algorithms following the filter approach in terms of the number of reductive set attributes and classification accuracy.

In this paper, a fuzzy finite element method (FFEM) for determining the responses of structures is proposed by using the transformation between fuzzy and random variables. Firstly, the formulae for establishing normal random variables equivalent to symmetric triangular fuzzy numbers are presented based on the combination of the principle of insufficient reason and that of maximum specificity.

Conventional reliability theory comprises two core hypotheses: (A) the probability assumption and (B) the binary-state assumption. The probability assumption requires full characterization of the system behavior in the context of the probability evaluation, whereas the binary-state assumption assumes that the system has only two states at any time. These two states are the functioning state and the failed state.

The research questions formulated for the study, the papers were classified into various MCDM approaches, website genre, number and list of criteria used over the years and the localization of websites based on country. Some of the findings showed that the Analytical Hierarchy Process approach integrated with fuzzy logic has been the most common method over the years.

A rainfall – runoff model describes the relation between the rainfall and runoff for a particular catchment area. The relationship between rainfall in a period and the corresponding runoff is quite complex. SCS-CN method is used to estimate the runoff, but, SCS-CN method does not consider the impact of rainfall intensity and did not account for the influence of forest management practices. The aim of this study is to develop Fuzzy Logic Model to estimate runoff using rainfall given for the area under consideration.

In this study a multi-stage multi-objective transportation model is developed with fuzzy relations. Minimization of both cost and time of transportation are considered as two different objectives of first stage which are associated with a number of different criteria like detortion time, fixed charge and mode of transportation. In second stage, another objective i.e quantity of transported amount is considered on the basis of previous two objectives.

This paper deals with the problem of grouping a set of objects into clusters. The objective is to minimize the sum of squared distances between objects and centroids. This problem is important because of its applications in different areas. In prior literature on this problem, attributes of objects have often been assumed to be crisp numbers.

The advantage of using this model includes the optimal facilities, locating them and assigning the optimal facilities to them. It also chooses the type and the number of technologies, which must be bought. The fuzzy programming converts the multi objective model to an auxiliary crisp model by Jimenez approach and solves it with ߝ-constraint. For solving large size problems, the Multi Objective Differential Evolutionary algorithm (MODE) is applied.

In this article, we consider a single-unit unreliable production system which produces a single item. During a production run, the production process may shift from the in-control state to the out-of-control state at any random time when it produces some defective items. The defective item production rate is assumed to be imprecise and is characterized by a trapezoidal fuzzy number.
