  • System of systems analytic hierarchy and stochastic optimisation design

    A formulated methodology of developing the system of systems analytical hierarchy and optimisation flow order is presented. The design problem is modelled as a multi-level hierarchical optimisation problem. The multi-levels such as, super system level, system level and subsystem level are defined. Based on the idea of system of systems, each system performance criteria can be decomposed into ...

  • Optimal closure of system actuators for transient control: an analytical approach

    The effect of downstream valve closure scheduling was analyzed to find optimal closure parameters that lead to the minimal maximum pressure head in the water distribution system. Several valve closure strategies were explored, combining the known valve performance curve (change in flow as a function of change in valve's opened area) with unknown valve closure curve (change in valve's opened ...

  • An approximate analytical method to size an air vessel in a water supply system

    The size parameters of an air vessel, mainly including its initial gas volume and total volume, account for its performance in hydraulic transients. Traditionally, the size of an air vessel in a given water supply system is estimated by trial and error, usually aided by computers. To simplify the preliminary estimation of the air vessel's volume, in this paper, an approximate analytical method ...

  • Analytical model for uni–directional flow passive soil vapour extraction system

    An analytical one–dimensional model has been developed to examine the uni–directional barometric pumping in passive Soil Vapour Extraction (SVE) system. The model is applicable to a special case in which a radial flow field is insignificant. The system considered contains two unsaturated zone layers, an upper contaminated low permeability layer and a lower high permeability layer contains a well ...

  • Development of intelligence analytic models for integrated building management systems (IBMS) in intelligent buildings

    With the availability of innumerable 'intelligent' building products and the dearth of inclusive evaluation tools, design teams are confronted with the quandary of choosing the apposite building control systems to suit the needs of a particular intelligent building project. The paucity of measures that represent the degree of system intelligence and indicate the desirable goal in intelligent ...

  • Integration of an analytic element model in a stochastic analysis of infiltration into a complex unconfined aquifer system

    ABSTRACT A hydrologic model based on the Analytic Elements Method (AEM) has been developed for a phreatic aquifer in the General Separations Area (GSA), of the Savannah River Site (SRS), South Carolina, USA. The AEM is a semi-analytical method that relies on the superposition of individual closed-form solutions of elements representing the main hydrologic features of a site. Our study adopts ...

  • Analytical Support for Cost-Effective Pollution Control

    ' Analytical tools have been developed by the World Bank Group to estimate rapidly the extent and impacts of pollution in a given situation and to support decisions on pollution management. These tools help decision makers to overcome the frequent lack of data on emissions from different sources, their impact on ambient quality, and mitigation alternatives.' Decision Support System for ...

  • Use of analytic hierarchy process and fire dynamics simulator to assess the fire protection systems in a tunnel on fire

    The road and rail tunnels are increasing in number. Corresponding to this higher number of tunnels, a higher number of accidents related to safety problems occur. The safety of road and rail tunnels is mostly related to fire safety. Our purpose in this paper is to present a new integrated approach to the analysis of fire safety in tunnels. Using different techniques from the decision support ...

  • Predictive Analytics Will Be Critical to Beating the Driver Shortage

    The number of people working in the U.S. trucking industry hit an all-time high in December: 1.47 million, according to the U.S. Department of Labor. That’s impressive — and great for the industry — but in no way does it eliminate the intense, industry-wide concern about and focus on the enormous projected need for more drivers every year through at least 2030.  ...

  • Process analytics in methanol plants – Case Study

    Methanol is a clear liquid usually made from natural gas. It is a clean burning fuel, containing almost no sulphur or nitrogenous materials. It is a petrochemical that is used to make countless industrial and consumer products. In the future, methanol could be used as a source of hydrogen for fuel cells. Different concepts are in use to produce methanol looking always for higher plant efficiency ...

  • Process analytics in claus plants – Case Study

    Sulfur recovery The relatively high sulfur content of the still available crude oil and natural gas reserves and the more stringent standards for sulfur emissions from oil, gas, and chemical processing facilities demand reliable and cost effective technologies for sulfur recovery. Sulfur recovery refers to the conversion of hydrogen sulfide (H2S) as byproduct of natural gas plants and ...

  • Utilizing analytic hierarchy process (AHP) for decision making in water loss management of intermittent water supply systems

    Increasing water demands, in parallel with water scarcity, force water utilities in developing countries to follow complex operation techniques for the distribution of the available amounts of water. The reduction of water losses from water supply systems can help fill the gap between supply and demand. This strategy is characterized by the variety of options, and identification of the most ...
