====== Project Portal for OMG® Uncertainty Modeling (UM) ======
===== Current Objective of the site =====
This wiki site is currently being used as a site for sharing information about Uncertainty Modeling and the related standardization activities at OMG®.
===== Uncertainty RFP =====
The Uncertainty Modeling Working Group has been formed. Please see below the list of organizations and main contact person, who have shown their interests as a working group towards the submission of Uncertainty RFP to OMG. 
==== RFI Objectives ====
The intent of the RFI is to gather information for the purpose of guiding a group in its efforts to provide solutions to industry problems. The RFI process is used to canvass a targeted industry segment for one or more of the following purposes:
  * Acquiring industry requirements.
  * Identifying potential technology sources.
  * Soliciting input to validate the roadmap of the group.
=====News=====
==== Uncertainty Modeling RFP has been submitted and has been added to the Burlingame AB and PTC agendas for review and issuance.

==== Presenting the Uncertainty Modeling standardization activities at OMG® Brussels Technical Meeting on June 7th, 2017 ====
This signifies the kickoff of the preparation of Uncertainty RFP. 
==== Introducing Uncertainty to Requirements Specification/Modeling at SysML V2 RFP Requirements ====
A great initiative is being made to introduce uncertainty to specify/model requirements in the future standard of SysML V2. Details can b found from [[http://www.omgwiki.org/OMGSysML/doku.php?id=sysml-roadmap:requirement_concepts_modeling_core_team|the OMG SysML Portal]].
==== The first BrightTalk Webinar hosted by OMG®, given by Tao Yue, Shaukat Ali and Bran Selic ====

==**About this webinar:**==
The importance of facing, understanding, predicting and even mitigating uncertainty has been well acknowledged and studied in various fields such as philosophy, physics, and finance.

In terms of software and system engineering, due to the increasing complexity of large-scale systems themselves, and the dynamic and unpredictable deployment and operation environments of such systems, increasing attentions have been given to address challenges of explicitly specifying and modeling uncertainty.

Uncertainty Modeling (UM) aims to promote and enable explicit specifications of uncertainty and uncertainty related concepts, at various contexts (e.g., developing large-scale Cyber-Physical Systems and Internet of Things, for different purposes (e.g., enabling uncertainty-wise requirements specifications, modeling, verification and validation, e.g., facilitating the definition of uncertainty-wise testing strategies), and at different phases of the development of such complex and uncertainty inherent systems (e.g., requirements, architecture, design, testing and operation).

In the context of OMG®, we see a diverse set of uncertainty modeling applications, such as 1) integrating with OMG's Unified Modeling Language™ (UML) use cases, Systems Modeling Language™ (SysML™) Requirements Diagram, to enable requirements V&V, 2) capturing uncertainty as part of SysML or UML models to facilitate design and/or testing, 3) integrating with Business Process Model and Notation™ (BPMN™) and other OMG® standards to facilitate different kinds of analyses and generations.

OMG®’s Uncertainty Modeling Request for Information (RFI) is currently open for responses. The RFI aims to solicit ideas, discussions, comments, recommendations, user needs and experiences about uncertainty modeling. Collected responses will be carefully analyzed and will be used to identify requirements, based on an RFP for a UM will be developed. Instructions for responding to this RFI are specified in the OMG's Uncertainty Modeling Request for Information document ([[http://www.omg.org/cgi-bin/doc.cgi?ad/2016-9-2|ad/16-09-02 (Uncertainty RFI)]]).
