A Rigorous Approach to Relate Enterprise and Computational Viewpoints
Multiviewpoint approaches allow stakeholders to design a system from stakeholder-specific viewpoints. By this, a separation of concerns is achieved, which makes designs more manageable. However, to construct a consistent multiviewpoint design, the relations between viewpoints must be defined precisely, so that the consistency of designs from these viewpoints can be verified. The goal of this paper is to make the consistency rules between (a slightly adapted version of) the RM-ODP enterprise and computational viewpoints more precise and to make checking the consistency between these viewpoints practically applicable. To achieve this goal, we apply a generic framework for relating viewpoints that includes reusable consistency rules. We implemented the consistency rules in a tool to show their applicability
Automated Mapping of UML Activity Diagrams to Formal Specifications for Supporting Containment Checking
Business analysts and domain experts are often sketching the behaviors of a
software system using high-level models that are technology- and
platform-independent. The developers will refine and enrich these high-level
models with technical details. As a consequence, the refined models can deviate
from the original models over time, especially when the two kinds of models
evolve independently. In this context, we focus on behavior models; that is, we
aim to ensure that the refined, low-level behavior models conform to the
corresponding high-level behavior models. Based on existing formal verification
techniques, we propose containment checking as a means to assess whether the
system's behaviors described by the low-level models satisfy what has been
specified in the high-level counterparts. One of the major obstacles is how to
lessen the burden of creating formal specifications of the behavior models as
well as consistency constraints, which is a tedious and error-prone task when
done manually. Our approach presented in this paper aims at alleviating the
aforementioned challenges by considering the behavior models as verification
inputs and devising automated mappings of behavior models onto formal
properties and descriptions that can be directly used by model checkers. We
discuss various challenges in our approach and show the applicability of our
approach in illustrative scenarios.Comment: In Proceedings FESCA 2014, arXiv:1404.043
Requirements modelling and formal analysis using graph operations
The increasing complexity of enterprise systems requires a more advanced
analysis of the representation of services expected than is currently possible.
Consequently, the specification stage, which could be facilitated by formal
verification, becomes very important to the system life-cycle. This paper presents
a formal modelling approach, which may be used in order to better represent
the reality of the system and to verify the awaited or existing systemâs properties,
taking into account the environmental characteristics. For that, we firstly propose
a formalization process based upon properties specification, and secondly we
use Conceptual Graphs operations to develop reasoning mechanisms of verifying
requirements statements. The graphic visualization of these reasoning enables us
to correctly capture the system specifications by making it easier to determine if
desired properties hold. It is applied to the field of Enterprise modelling
Congruency fit: beyond performance in the auto supplier industry
The effects of manufacturing strategy (MS) and technology (T) on performance have been
studied separately, but few studies have examined the relationship between MS and T practices
clusters that improve effectiveness when implemented jointly, and even then they do not
consider possible congruency between the two. This paper develops a congruency (selection)
model to test for any interconnection between said clusters, without addressing causation or their
combined effect on performance. The implicit outcome is that the plant will achieve a desirable
effectiveness level. Through a wide-ranging survey of auto supplier plants, two approaches are
considered: 1) grouping both clusters in pairs (canonical correlation analysis); and 2) a more
general selection view version, with practices from both clusters related multidimensionally and
subordinated by bivariate analysis (regression) to test for any congruent pattern. Both methods
find a congruent relationship between manufacturing strategy and technology practice clusters,
although the second provides greater detail.Ministerio de EducaciĂłn y Ciencia DPI-2006-0553
