Minimum and maximum operators are two well-known t-norm and s-norm used frequently in fuzzy systems. In this paper, two different types of fuzzy inequalities are simultaneously studied where the convex combination of minimum and maximum operators is applied as the fuzzy relational composition. Some basic properties and theoretical aspects of the problem are derived and four necessary and suffi...

in this paper, the researchers present a multi-objective linear fractional inventory model using fuzzy pro-gramming. the proposed method in this paper is applied to a problem with two objective functions. the re-sulted fuzzy model is transformed into an ordinary linear programming. the implementation of the develop-ing model presented in this paper is demonstrated through the use of some numeri...

All the current rate-based proposals suggest to adjust the source transmission rate based on the received RM cell immediately. However, this approach may lead to overloading of the bottleneck switch. We propose that the adjustment should be delayed. The amount of delay depends on the source-to-bottleneck separations of diierent connections, which can be obtained during the call setup. Based on ...

Abstract. We investigate a variation method where the trial function is generated from the application of a variable operator on a reference function. Two conditions are identified, one for obtaining a maximum and another for a minimum. Although the conditions are easy to understand, the overall formulation is somewhat unusual as each condition gives rise to a two-step variation process. As an ...

We generalize a smoothing algorithm for finite min–max to finite min– max–min problems. We apply a smoothing technique twice, once to eliminate the inner min operator and once to eliminate the max operator. In mini–max problems, where only the max operator is eliminated, the approximation function is decreasing with respect to the smoothing parameter. Such a property is convenient to establish ...

The object of research is the Fučik spectrum for (p,q)-Laplacian operator. In present paper, we are going to introduce notion a non-linear, non-homogeneous operator, which operator through study following eigenvalue boundary problem: {–∆pu–∆qu=λ(u+)p–1–μ(u–)q–1 in Ω, u=0 on ∂Ω, where Ω⊂RN, N≥1 bounded open subset with smooth and λ μ two real parameters. order establish show existence non-trivia...

Operator radiation exposure during percutaneous transluminal coronary angioplasty as compared with that during routine coronary angiography is unknown. Therefore, cumulative radiation exposure at operator eye level was measured in two physicians (operators 1 and 2) during performance of coronary angioplasty and routine coronary angiography. The physicians participated together during angioplast...
