  This volume contains the proceedings of the 1st International Workshop on
Methods and Tools for Rigorous System Design (MeTRiD 2018), held on the 15th of
April, 2018 in Thessaloniki, Greece as part of ETAPS 2018, the European Joint
Conferences on Theory and Practice of Software.
  The term "Rigorous System Design" (RSD) denotes the design approach that is
based on a formal, accountable and iterative process for deriving trustworthy
and optimised implementations from models of application software, its
execution platform and its external environment. Ideally, a system
implementation is derived from a set of appropriate high-level models by
applying a sequence of semantics-preserving transformations.
  The ambition of MeTRiD is to promote the use of formal methods, in general,
and the RSD approach, in particular, in the industrial applications and,
reciprocally, bring the attention of the formal methods researchers to such
industrial applications in order to develop realistic case-studies and guide
the evolution of tools. Striving towards this ambitious goal, we have solicited
contributions of three types:
  - regular papers, presenting original research
  - case study papers, reporting the evaluation of existing modelling,
analysis, transformation and code generation formalisms and tools on realistic
examples of significant size
  - tool papers, describing new tool prototypes supporting the RSD flow and
enhancements of existing ones
  We have received 13 submissions (7 regular, 4 tool and 2 case study papers),
whereof 8 have been accepted for presentation at the workshop:
  - 5 regular papers
  - 2 tool papers
  - 1 case study paper
  In this volume, these papers are complemented by an invited paper by Joseph
Sifakis.
