Lower and Upper Bound of the Laplacian Energy with Real and Complex Roots of an Intuitionistic Fuzzy Directed Graph
by B. PRABA, G. DEEPA, V.M. CHANDRASEKARAN
Abstract: In this paper, the concept of Laplacian energy of a fuzzy graph is extended to the Laplacian energy of an intuitionistic fuzzy directed graph. The degree matrix and the Laplacian energy of an intuitionistic fuzzy directed graph are defined. The upper and lower bound are derived for the Laplacian energy of an intuitionistic fuzzy directed graph. Existing work has been conjectured that the inequality holds for all graphs. But we are conjectured that the inequality does not hold for an intuitionistic fuzzy directed graph. Finally, numerical examples are illustrated for the defined work. Moreover, we analyzed the results for the energy of an intuitionistic fuzzy directed graph and Laplacian energy of an intuitionistic fuzzy directed graph.
Keywords: Energy of a graph; Energy of a fuzzy graph; Energy of an intuitionistic fuzzy graph; Laplacian energy of a graph; Laplacian energy of a fuzzy graph.
The inventory-routing problem in field supply logistics
by Yi Shu Ping, Li Yu Lin
Abstract: This paper considers the application units (AUs) operating within cropping fields as the "customers", and the farm depots as the "suppliers", while taking the fuel consumption rare (FCR) as a cost factor and adding it to the IRP. Then a dedicated classification of field supply logistics is devised based on a modified classification scheme and tailored to a conceptual application of the IRP. The research results show that delivery scheduling and planning problems in field supply logistics can be cast as IRP instances and solved by their corresponding methods. Overall, the adoption and modification of the IRP methodology provide a promising approach for the process improvement of field supply logistics.
Keywords: agricultural field logistics; inventory management; vehicle routing; classification; conceptual application.
Construction of Structural Reference Model for ERT Data Inversion in Heavy Metal Contaminated Sites Surveys
by Wang Yuling
Abstract: ERT surveys can provide useful information on heavy metal contaminated sites assessment. Structural reference model is introduced as a constraint to guide ERT data inversion in ERT survey. In this paper, we propose a novel method which integrate soil physical and chemical information into structural reference model construction for ERT data inversion to improve the accuracy of inversion results. The reference model consists of two parts: contaminated area and uncontaminated area. The scope of contaminated areas is recognized using soil physical and chemical properties and the apparent resistivity data extracted from the ERT profile at the borehole location, and then the resistivity distribution of reference model is set according to the average resistivity of soil samples. The accuracy of the proposed method is evaluated with two numerical experiments. The experiment results of synthetic models show that the structural reference model constructed by the proposed method is close to the synthetic model and effectively improves the inversion results.

Flag State Policies and Labour Dynamics in the Shipping Industry
by Aristotelis Alexopoulos, Evangelos Sambracos
Abstract: This paper focuses on the problem of state policies and labour dynamics in the shipping industry by applying a system dynamics methodology. Traditional flag states, such as Greece, has been facing serious problems with regard to its national shipping policy, that is to say, the flagging out from the Greek flag towards open registries and the depletion of the Greek maritime workforce during the last decades. Its response, in terms of state policies, has so far met with little success. This is largely due to the complex dynamic nature of state intervention and protectionist policies, which makes it extremely difficult to achieve the desired effects. This work is still in progress and this paper presents an initial approach to the problem, as well as some insights gained.

On Generalized Intutionistic Fuzzy Divergence
by Anjali Munde
Abstract: Atanassov  defined the notion of intuitionistic fuzzy sets (IFS), which is a generalization of thernconcept of fuzzy sets, introduced by the Zadeh . IFS theory has been extensively applied to areas likernArtificial Intelligence, Networking, Soft decision making, Programming logic, operational research etc. Onernof the promising role of IFS has been emerged in Decision making Problems. In some real-life situations,rndecision makers may not be able to accurately express their view for the problem as they may not possess arnprecise or sufficient level of knowledge of the problem or the decision makers are unable to discriminaternexplicitly the degree to which one alternative are better than others in such cases, the decision maker mayrnprovide their preferences for alternatives to a certain degree, but it is possible that they are not so sure aboutrnit. Thus, it is very suitable to express the decision maker preference values with the use of fuzzy/intuitionisticrnfuzzy values rather than exact numerical values or linguistic variables Szmidt and Kacprzyk ,,. Tornsatisfy the need of decision making problem with imprecision and uncertainty many researchers have beenrnconcentrated on IFS theory. In the present communication, generalized measures of intutionistic fuzzyrndivergence with the proof of their validity are introduced.
