The world’s population grows yearly, so increasing food production is necessary, to meet consumer demands. This must be clean; thus, sustainable agriculture seems represent a solution. However, social, economic, and environmental barriers impede the adoption of this practice. Therefore, research identified these barriers, according sustainability triple-bottom line through literature review, an...

Abstract Sustainable development necessitates the implementation of appropriate policies that integrate multiple competing objectives on economic, environmental, energy, and social criteria. Multi-criteria decision analysis with goal programming is a popular widely used technique for studying problems objectives. Real-world situations frequently involve imprecise incomplete information, making ...

Information systems, which contain only crisp data, precise and unique attribute values for all objects, have been widely investigated. Due to the fact that in realworld applications imprecise data are abundant, uncertainty is inherent in real information systems. In this paper, information systems are called fuzzy information systems, and formalized by (objects; attributes; f), in which f is a...

Social interactions can be seen as service exchanges, followed by the qualitative evaluation of those exchanges by means of social exchange values. This paper introduces an approach based on Fuzzy Logic for the evaluation of the investment and satisfaction values generated in personality-based social exchanges in multiagent systems. The fuzzy equations of material social equilibrium, associated...

Abstract In this Paper a multi item EOQ model with stock dependent demand for deteriorating items is considered in fuzzy environment. Inventory costs such as holding cost and setup cost have been represented by exponential membership function and profit, deteriorating rate and total investment constraint are represented by linear membership functions. The model has been solved by fuzzy non-line...

BACKGROUND Over the past decade, substantial global investment has been made to support health systems and policy research (HSPR), with considerable resources allocated to training. In Canada, signs point to a larger and more highly skilled HSPR workforce, but little is known about whether growth in HSPR human resource capacity is aligned with investments in other research infrastructure, or wh...

The construction industry in the United States and other parts of the world has been facing several challenges, including a shortage of skilled workers. A review of the relevant body of knowledge indicates that one of the key reasons for this problem is the absence of human resource management strategies for construction workers at project, corporate, regional, or industry levels. This paper ad...

OBJECTIVES To identify research support strategies likely to be effective for strengthening the UK's dementia research landscape and ensuring a sustainable and competitive workforce. DESIGN Interviews and qualitative analysis; systematic internet search to track the careers of 1500 holders of UK doctoral degrees in dementia, awarded during 1970-2013, to examine retention in this research fiel...

The objective of our research is to build a statistical test that can evaluate different risks of a portfolio selection model with fuzzy data. The central points and radiuses of fuzzy numbers are used to determine the portfolio selection model, and we statistically evaluate the best return by a fuzzy statistical test. Empirical studies are presented to illustrate the risk evaluation of the port...

This paper proposes an entropy method for diversified fuzzy portfolio selection. Proportion entropy is introduced and credibilistic mean-variance and mean-semivariance diversification models for fuzzy portfolio selection are proposed. The crisp forms of the proposed models are also provided when the security returns are all triangular fuzzy variables. As an illustration, an application example ...
