abstract = "Motivated by the needs of the Integration and Testing Laboratory
(LIT) of the Brazilian Institute for Space Research (INPE), this
paper aims to analyze how the information of space products life
cycle processes are determined from the models used for their
development, considering a model-based approach. With a focus on
Space Systems Engineering, exemplified with the satellites
Assembly, Integration and Testing (AIT) process, we analyzed the
relationship between Systems Engineering models with a future
Information System to support the product lifecycle process. There
are various business processes to perform the satellite life cycle
phases. Integrated with each other, they deliver the final result.
A business process is a set of activities or related tasks that
are performed to deliver an expected result. Information Systems
are a good way to improve the business processes performance. AIT
is one of the satellite life cycle processes. Doing AIT is so
complex and many equipment, people, tasks and information are
involved in it. So far, at LIT/INPE there is not an Information
System that support the whole AIT process practiced there, and the
storage and exchange of AIT information is document based. The use
of documents as a primary source of data makes it difficult to
retrieve information during the process, requires a lot of effort
from the team involved in it, and sometimes causes delays in
activities. There is a worldwide trend for a shift from the
document-centric to the model-centric approach to engineering
complex systems. Model Based Systems Engineering (MBSE) improves
Systems Engineering practices using models to represent the system
in various aspects. Models are built to represent requirements,
structure and behavior of systems. These models, among other
advantages, become consistent and reliable sources of information
to support the various phases of the product lifecycle. Concerning
the LIT case, the MBSE benefits as well as the adoption of
Information Systems can improve the AIT process. We must consider
that build good models that faithfully represent a system demands
effort and skilled workforce. Equivalent effort and workforce are
needed to build Information Systems that faithfully meet the needs
of a business process. There is a relationship between these two
activities and collaboration between them can be helpful to reduce
development effort.",
