Institute for Chemistry and Biology of the Marine Environment WG Integrative Modelling D. Kraft: Specific aspects of MSP implementation: Dealing with alternatives: scenarios and other decision-supporting systems Basic ideas: We understand spatial planning on the coast and in sea as a decision-making process To participate, someone needs information iDSS are systems to manage and provide knowledge

Institute for Chemistry and Biology of the Marine Environment WG Integrative Modelling D. Kraft: Specific aspects of MSP implementation: Dealing with alternatives: scenarios and other decision-supporting systems Decision-making process: Decision-making is a cognitive process leading to the selection of a course of action from different options. It consists of the mental process of thinking involved with the process of judging the merits of options and selecting one of them for action. Every decision-making process produces a final choice. (wikipedia, )

Kraft: Specific aspects of MSP implementation: Dealing with alternatives: scenarios and other decision-supporting systems Dealing with uncertainty: scenario analysis Uncertainty: A state of having limited knowledge where it is impossible to exactly describe... future outcome... Scenario analysis: A process of analyzing possible future events by considering alternative possible outcomes. Consider: Think carefully about (something), typically before making a decision.
