• OBJECTIVES, VISION OF FUTURE
• DCE ESA-TOS research study
• Goals
• New approach in performing engineering activities
  along the different phases of any project life
  cycle
• evaluating and presenting the benefits of
  applying distributed collaborative engineering in
  real space projects

4

• OBJECTIVES, VISION OF FUTURE (cont.)
• Shortening the development cycle and costs
• Taking advantage of synergy/opinions of different
  disciplines
• Early detecting engineering bottlenecks in the
  design
• Allowing identification and implementation of
  technical as well as managerial solutions
• Supporting Rapid Prototyping
• Sharing design and simulation data

PAST EXPERIENCE Alenia Spazio expertise ? use
of high performance network, ? state-of-the-art
tools ? collaborative engineering methodology ?

• PAST EXPERIENCE (cont.)
• DSE (Distributed Systems Engineering)
• DSE main goals
• The DSE Environment was intended to support
  large scale application of Collaborative
  Engineering Platforms within the European
  Organisations, supporting the whole System
  Engineering Life Cycle.
• DSE put special emphasis on Design and
  Verification activities in large, International
  projects.

7

• PAST EXPERIENCE (cont.)
• DSE (cont.)
• The project aim was in particular focused at
  enabling
• Distributed System Design Analyses Tasks
• distribution and collaborative evaluation of
  analysis and simulation results
• Distributed Design Reviews
• consolidation of the systems design in a
  distributed Review Team.
• Distributed Systems Verification Engineering
  Process
• from preparatory phases and up to the evaluation
  of system test results

• DCE NEEDS
• ? On demand Connectivity
• ? Quality of Service Management
• ? Ubiquitous Access (Office, Home, On-trip)
• ? On-demand Bandwidth
• ? IP services provisions

10

• DCE PARADIGMS
• Systems Engineering Data Exchange and Tools
• Interoperability
• Distributed Simulation
• Distributed Systems Architecture
• Human-Systems Interaction

Use of standard e.g. HLA- IEEE
11

• STEPS TO REALISE OBJECTIVES
• Analyze Space System Development Process
• (ECSS-E-10B Space Systems Engineering)
• Identify tasks that can be carried out in a more
  efficient way using the tools and methods
  developed in the frame of the DSE project
• Identify tasks that are currently not carried out
  in projects due to prohibitive costs or lack of
  feasibility, which could be enabled by the
  methods and tools developed in the frame of the
  DSE project

12

• STEPS TO REALISE OBJECTIVES (cont.)
• Evaluate DSE Methods and Tools
• Technical perspective
• ? performance, robustness maturity of the
• technology adopted
• ? Required infrastructure to be established
• ? Complexity of the overall system
• ? Training required to apply the technology in
  real work
• Project Perspectives
• ? Added value for space projects
• ? Affordability
• ? Potential for adoption in space projects

STEPS TO REALISE OBJECTIVES (cont.) Evaluate DSE
Methods and Tools
14

• STEPS TO REALISE OBJECTIVES (cont.)
• Analysis of Adoption by Space Projects
• ? Define quantitative evaluation criteria to
  determine
• the added value of DSE methods and tools w.r.t.
  theconventional approach.
• ? Identify and propose a suitable strategy to
  introduce
• the DSE methodology in space projects (e.g.
  scientific satellites, commercial satellites,
  conventional as well as mini, micro and nano
  satellites etc.)

15

• STEPS TO REALISE OBJECTIVES (cont.)
• Potential Pilot Projects
• ? Identify concrete space projects where a
  demonstration of the DSE methods and tools could
  be attempted
• ? Identify and analyze implementation constraints
  to apply such methods and tools in a typical
  space project

Proposal for Demonstration

How to apply Collaborative Engineering to Space
projects ? Smooth approach Distribution
transparency Easy to use Engineering oriented
17
Smooth approach

• Comply with
• existing processes and organisations
• Projects schedule constraints
• Efficiency in a distributed meeting is not innate
  for a large number of participants

• feasibility
• users satisfaction
• performances
• HCI
• audio/video/data comms

18

• Distribution transparency
• Middleware
• Minimal application adaptation
• Portability
• Network
• Performance
• Security (firewall company policies)

• Data access
• Confidentiality
• Integrity

Use of standards
19

• Easy to use
• Allow to share own-style of working
• chat / whiteboard
• application sharing
• distributed simulation
• Web-style navigation on data repository
• Session Management
• Chairman role resulted very important
• Keep session participants informed of occurring
  events

20

• Engineering oriented
• Continuous involvement of real engineers in
  real projects
• to verify effectiveness of the adopted solutions
• to get direct feedbacks on the proposed solutions
  and paradigms
