in this paper, a new approach for solving the second order fuzzy differential equations (fde) with fuzzy initial value, under strongly generalized h-differentiability is presented. solving first order fuzzy differential equations by extending 1-cut solution of the original problem and solving fuzzy integro-differential equations has been investigated by some authors (see for example cite{darabi...

the present article investigates the application of high order tsk (takagi sugeno kang) fuzzy systems in modeling photo voltaic (pv) cell characteristics. a method has been introduced for training second order tsk fuzzy systems using anfis (artificial neural fuzzy inference system) training method. it is clear that higher order tsk fuzzy systems are more precise approximators while they cover n...

Congruence proofs for bisimulation equivalences on higher{order process calculi tend to be signiicantly more complex than their counterparts in rst{order process algebra frameworks. The fact that higher{order synchronization invokes substitution seems to be the main problem. The reason is that it renders standard rst{order proof techniques circular in the higher{order case, and this situation i...

We characterize a fuzzy partial order relation using its level set, find sufficient conditions for the image of a fuzzy partial order relation to be a fuzzy partial order relation, and find sufficient conditions for the inverse image of a fuzzy partial order relation to be a fuzzy partial order relation. Also we define a fuzzy lattice as fuzzy relations, characterize a fuzzy lattice using its l...

In this review article we present results regarding the fuzzy order relations.The concept of fuzzy order was introduced by generalizing the notion of reflexivity, antisymmetric and transitivity.

Deterioration cannot be avoided in business scenarios. Deterioration is defined as change, damage, decay, spoilage obsolescence and loss of utility or loss of original value in a commodity that results in the decreasing usefulness from the original one product. Normally inventory models of deteriorating items, such as food products, vegetables, etc. involve imprecise parameters, like imprecise ...

in the present paper, a partial order on a non- archimedean fuzzymetric space under the  lukasiewicz t-norm is introduced and fixed point theoremsfor single and multivalued mappings are proved.

The bipolar fuzzy (BF) set is an extension of the used to solve uncertainty having two poles, positive and negative. rough a useful mathematical technique handle vagueness impreciseness. major objective this paper analyze notion approximation BF ideals semirings by combining theories sets. Then, idea subsemirings (ideals, bi-ideals interior ideals) developed. In addition, are characterized uppe...

Congruence proofs for bisimulation on higher{order process calculi tend to be signiicantly more complex than their counterparts in rst{order process algebra frameworks. Moreover, a standard technique that allows us to cover strong forms of bisimulation on higher{order calculi seems to fail for the corresponding weak forms. Similar problems are posed by applicative simulation on {calculi and our...
