Integrated Decision Making for Ground Handling Management
Published In: GJSFR Part: F: Mathematics & Decision Volume: 15 Issue: 1
In this paper a hierarchical structure for the management of airport ground handling activities is proposed. The main decision making processes in charge of the managerial units composing a proposed ground handling management organization are considered. The global objective is to turn available the ground handling resources so that arriving and departing flight are serviced with as litt...

How to Prove the Riemann Hypothesis
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 7
I have already discovered a simple proof of the Riemann Hypothesis. The hypothesis states that the nontrivial zeros of the Riemann zeta function have real part equal to 0.5 . I assume that any such zero is s =a+ bi .I use integral calculus in the first part of the proof. In the second part I employ variational calculus. Through equations (50) to (59) I consider (a) as a fixed exponent , ...

Correspondence between Fuzzy Multisets and Sequences
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 7
Although fuzzy multisets or fuzzy bags are very interesting in terms of applications, it is less study or explore by researchers. Fuzzy multiset is applicable as a model of information retrieval because it has the mathematical structure or framework which expresses the number and the degree of attribution of an element simultaneously. We present a concise note on fuzzy multisets as the f...

Multi-Objective Geometric Programming in Multiple-Response Stratified Sample Surveys with Quadratic Cost Function
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 7
In this paper, the problem of multiple-response in stratified sample surveys has been formulated as a multi-objective geometric programming problem (MOGPP). The fuzzy programming is described for solving the formulated MOGPP. The formulated MOGPP has been solved by Lingo software and the dual solution is obtained. Subsequently with the help of dual solution of formulated MOGPP and the pr...

Bianchi Type-IX Dark Energy Model in Sen-Dunn Scalar-Tensor Theory of Gravitation
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 7
Bianchi type-IX cosmological model with variable equation of state (EoS) parameter have been investigated in general scalar-tensor theory of gravitation proposed by Sen and Dunn (J. Math. Phys. 12:578, 1971) when universe is filled with Dark Energy. The field equations have been solved by considering the scale factors in two different forms (i) ()ltretR1= , where r and l are positive con...

Solution of Complex Differential Equation System by using Differential Transform Method
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 6
In this study, using differential transform method second order complex differential equation system was solved. Firstly we seperated real and imaginer parts these equations system. Thus from two unknown equation system four equality was obtained. Later using two dimensional differential transform we obtained real and imaginer parts of solutions. ...

mz-Compact Spaces
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 6
In this work we study mz-compact spaces and mz-Lindel of spaces, where m is an infinite cardinal number. Several new properties of them are given. It is proved that every mz- compact space is pseuodocompact (a space on which every real valued continuous function is bounded). Characterizations of mz-compact and mz-Lindel of spaces by multifunctions are given. ...
