uncertainty is undoubtedly an inevitable part of programming process. a lot of effective factors in the water resources’ performance are not deterministic while their values are surely needed for the design and implantation of water systems. since an optimal design of water distribution systems is in demand of a just evaluation of the costs, efficient operation of such systems calls for a prope...

One shortcoming of classic Descriptions Logics, DLs, is their inability to encode probabilistic knowledge and reason over it. This is, however, a strong demand of some modern applications, e.g. in biology and healthcare. Therefore, probabilistic extensions of DLs are attracting attention nowadays. We introduce the probabilistic DL SHIQP which extends a known probabilistic DL. We investigate two...

This paper proposes a new method to build probabilistic fire demand model (PFDM) investigate the structural behaviour of steel pipe-rack located within an industrial installation and exposed localised fire. The PFDM will serve develop fragility functions be used either in risk assessment or fully engineering (PSFE) framework. cloud analysis (CA) was exploited based on different parameters (EDP)...

Rationing occurs if the demand for a certain good exceeds its supply. In such situations a rationing method has to be specified in order to determine the allocation of the scarce good to the agents. Moulin (1999) introduced the notion of probabilistic rationing methods for the discrete framework. In this paper we establish a link between classical and probabilistic rationing methods. In particu...

Our incentive is to study the behaviour of lot-sizing rules in a multilevel context when forecast demand is subject to changes within the forecast window. To our knowledge, only Bookbinder and Heath (1988) proposed a lot-sizing study in a multi-echelon rolling schedule with probabilistic demands. But their simulation study was limited to two arborescent structures with 6 nodes. By means of an e...

The scientific study article(a monograph) , presents a forecast and estimate the evolution of the market demand. Key-Words: fuzzy sets, forecasting, estimating, statistical extrapolation, market demand. 1 Problem formulation Methods for forecasting 1.1 Probabilistic Model [10] The methods operate with certain statistical parameters. The most frequently used is the mean square deviation, namely:...

Characterization and evaluation of a biological submerged filter was carried out on a full-scale pilot plant performing removal of biochemical oxygen demand (BOD) and total nitrogen (TN) from pre-treated urban wastewater. The average influent values of BOD5, chemical oxygen demand (COD) and TN were 370, 1,015 and 60 mg/L, respectively. The pilot plant produced good discharge quality during stea...
