WP-4: Systems Engineering and Decision Support
Workpackage number: WP-4 Start date or starting event: 0
Participants: GR JO DZ Total PMPerson-months per participant: 17 11 4 32
O-4.1: To develop a system engineering software package for optimal design and performance analysis including technical, economic and ecological aspects
O-4.2: To develop a decision support tool to drive the designer through the necessary steps to the optimal design taking into account requirements for sizing, location, climatic conditions, etc.
O-4.3: To implement a database system to save the experiences, data and findings of the project to be used for the design and implementation
Description of work
T-4.1: Engineering principles and design tools (GR): The system engineering tools will be designed taking into account technical, economic and ecological aspects.
T-4.2: Database design and data collection (JO, DZ): The first level of the system consists of a methodology for data collection, processing and registration in the databases. Original raw data are often defective, requiring a number of pre-processing procedures before they can be registered in an understandable and interpretable way. Missing data and uncertainty must be also considered in this level.
T-4.3: Systems analysis environment (GR, JO): The second level includes the Systems Analysis
Environment for the development of different feasible technical and economic configurations for a specific project of co-generative water and power supply. Life cycle performance and cost analysis will be included and allow for identification of an optimal solution. The cost analysis will also include different economic evaluation models, such as cost-benefit analysis, profitability index analysis, and sensitivity analyses (e.g. with regard to diesel prices), in order to help in identifying the optimal solution. A potential assessment of environmental costs for power generation from conventional diesel generators will be included, as well.
T-4.4: Decision support system (GR): On the third level, an integration task that entails gathering and merging the conclusions derived from knowledge-based and numerical techniques is designed.
This level also raises the interaction of the users with the computer system through an interactive and graphical user–machine interface. Moreover, plans are formulated and presented to managers as a list of general actions suggested to solve a specific problem. The system has to recommend not only the action, or a sequence of actions (a plan), but also a value to estimate its correctness to help the decision-maker. In this task as well as in Task T-4.3, the study will not be only limited to a RO plants but also simple models of other desalinations processes will be included in order to produce a more general framework for assisting decision-making and selecting the optimal configuration.
