Abstract In this paper, an integration of a fuzzy-interval credibility-constrained (FIC) model expressed by fuzzy interval sets (FIS) and nonlinear programming (INP), termed FIC-INP model, was proposed applied to two cases. After formulating the upper lower disinfection booster costs can be obtained for cases under various combinations credibility levels limits. The results indicated that incre...

The systematic development of fault tolerant real time systems with guaranteed timeliness requires an appropriate system architecture and a rigorous design methodology The rst part of this paper describes those services of the architecture that help to simplify the work of the real time programmer taking MARS as an example The second part deals with the pro gramming in the large activities i e ...

The capacitated arc routing problem (CARP) is one of the most important routing problems with many applications in real world situations. In some real applications such as urban waste collection and etc., decision makers have to consider more than one objective and investigate the problem under uncertain situations where required edges have demand for more than one type of commodity. So, in thi...

The joint replenishment problem (JRP) has received considerable attention and all of the work on JRP is under explicit environment. In fact, the decision makers often have to face vague operational conditions. In this paper, a novel JRP model with fuzzy minor replenishment cost and fuzzy inventory holding cost is developed. More concisely, this model is a fuzzy dependent-chance programming (DCP...

Two new molecular algorithms are presented that are designed for the improvement of e ciency and reliability of DNA computing The rst algorithm introduces an evolutionary cycle to guide chemical reactions of DNA molecules The second molecular algorithm extends the rst one by adding another evolutionary loop for op timizing encodings of the problem instance Just as genetic programming is a metho...

This paper presents a data ow computer constituted of a large array of data ow processors and programmed using a functional language and its application to real time image processing The approach integrates tightly and e ciently the data ow architecture principle and the functional pro gramming concept It leads to a very simple and reg ular hardware It also provides a very e cient and user frie...

In fuzzy decision systems, we model insuring critical path problem by two-stage risk-aversion fuzzy programming. For the proposed two-stage insuring critical path problem, we first define three solution concepts, expected value solution, wait-and-see solution and here-and-now solution, then introduce the value of perfect information of value-at-risk (VaRVPI) and the value of the fuzzy solution ...

The equilibrium measure is a natural extension of both probability and credibility measures. The convergence modes of random fuzzy variables with respect to equilibrium measure is an important issue for research. In this paper, we first introduce several convergence concepts for sequences of random fuzzy variables, including convergence in equilibrium measure and convergence in equilibrium dist...

In this article, a capacitated location allocation problem is considered in which the demands and the locations of the customers are uncertain. The demands are assumed fuzzy, the locations follow a normal probability distribution, and the distances between the locations and the customers are taken Euclidean and squared Euclidean. The fuzzy expected cost programming, the fuzzy β-cost minimizatio...

In this paper, we investigate the properties of some recently pro-posed fuzzy distance measures. We find out some shortcomings for these dis-tances and then the obtained results are illustrated by solving several examplesand compared with the other fuzzy distances.
