This document provides a report of the work carried out in Task 3.3 Decision Support. It presents the specification and design of the Decision Support Service (DSS) implemented in the short-term approach of PHAROS, having in mind its long-term multi-hazard approach.
As a result of the requirements’ analysis and the interaction with end users and the Advisory Board (AB), it turned out that Incident Management (DSS-IM) functionality is required already in the short-term approach of PHAROS, implying the decision to design and implement this functionality as part of the PHAROS DSS. This activity has therefore been assigned to the tasks T3.1 and T3.3 and the specification and design of the Incident Management functionality has been integrated into the companion deliverables D3.1 and D3.2 .
This document presents shortly the overall architecture of the set of Decision Support Services and describes the role and purpose of the individual services, focusing on the Decision Support Service DSS-DS (see section 4). In general, the provision of decision support is based on two major steps: the generation and update of situation awareness (SAW), followed by the generation and update of decision proposals. Task 3.1 and the deliverables D3.1 (Draft)  and D3.2 (Final)  relate to the first step, while the decision support functionality and the decision support service itself is dealt within Task 3.3 and described in this deliverable and D3.7 (Final), to be submitted in M21.
Section 3 compiles the technical requirements that the DSS-DS described in this document need to address in order to comply with the user and system requirements described in Deliverable D2.8 (Draft) , D2.9 (Final)  and the PHAROS Requirements and System Engineering Deliverables (sequence of D2.4  to D2.7, currently D2.5 ), respectively.
The DSS-DS service described in this deliverable provides two types of resources: decision proposals and products. Decision proposals are directed to the user and contain notifications or recommendations to act upon. In case a dissemination action is proposed, appropriate products (in the PHAROS project termed alerts) are proposed, too. The DSS-DS provides proposals and alerts on a per-incident basis.
Tasks 3.1 and 3.5 contributed to this deliverable with respect to the overall DSS architecture and the development and specification of the shared Common Operational Picture (sCOP) format to describe situational awareness information.
The interaction with other components of PHAROS and the interfaces provided are described in section 6.
