Modelling Flexible Collaborative Process: The VCP2M Approach

This paper addresses the collaborative processes flexibility issue, which is an important issue in Business Process (BP) Management. Indeed, the strong competition in which organizations are involved lead them to frequently change and adapt their collaborative processes to face new client requirements or to benefit from new collaboration opportunities. More precisely, this paper proposes to adopt a version-based approach to support the modelling of flexible collaborative processes. First it introduces the VBP2M meta-model (Version of BP meta-model) supporting the modelling of flexible internal (i.e., intra-organizational) processes, and then explains how to extend it to define the VCP2M meta-model (Version of Collaborative Processes meta-model) to design flexible collaborative processes, which correspond to processes crossing the boundaries of companies. A specific case study illustrates the modelling of collaborative process versions as instances of VCP2M

Addressing inter-organisational process flexibility using versions: The VP2M approach

Process flexibility has been investigated in depth in the context of intra-organisational processes, but it is still an open issue when processes cross the boundaries of companies. In this paper, we address the modelling of flexible inter-organisational processes using a version-based approach. Indeed, versions are known to be a powerful technique to deal with variability, evolution and adaptation of processes, which are the three main needs of process flexibility. More precisely, this paper presents VP2M (Version of Process Meta-Model), a meta-model supporting the modelling of versions of inter-organisational processes, addressing both static and dynamic aspects of VP2M. It also illustrates process version modelling within the Subsea Pipeline process example

A Version-based Approach to Address Flexibility of BPMN Collaborations and Choreographies

Process flexibility is an important issue in the business process management area: it has mainly been investigated in the context of intra-organisational processes but it received little attention in the context of processes crossing the boundaries of companies. This paper addresses the issue of BPMN collaborations and choreographies flexibility, advocating a version-based approach. Indeed versions, which have been recognised as a powerful mechanism to face flexibility of internal processes of companies, are used to address flexibility of processes crossing the boundaries of companies, modelled as collaborations or choreographies in BPMN. Thus this paper extends BPMN collaborations using versions. It also introduces algorithms supporting the mapping from versions of collaborations into versions of choreographies. This paper mainly focuses on static aspects of collaboration and choreography versioning

Investigation on the Effects of Acoustic Liner Variation and Geometry Discontinuities on the Acoustic Performance of Lined Ducts

Noise reduction inside waveguide systems has gained momentum owing to a great interest in it. To attenuate the sound in a broad frequency range, this study aims to compare the effects of two acoustic liners, a perforated plate backed by an air cavity (PP-Air cavity), or by a porous material (PP-PM), on the acoustic behaviour of lined ducts using a numerical model to compute the multimodal scattering matrix. From this matrix, the reflection and the transmission coefficients are computed and therefore the acoustic power attenuation is deduced. Moreover, the effects of geometry of ducts with and without changes in the section are investigated. The numerical results are obtained for five configurations, including cases of narrowing and widening of a duct portion with sudden or progressive discontinuities. Accordingly, numerical coefficients of reflection and transmission as well as the acoustic power attenuation show the relative influence of acoustic liners in each type of configuration

Identification of Physical Parameters of a Porous Material Located in a Duct by Inverse Methods

Lined ducts with porous materials are found in many industrial applications. To understand and simulate the acoustic behaviour of these kinds of materials, their intrinsic physical parameters must be identified. Recent studies have shown the reliability of the inverse approach for the determination of these parameters. Therefore, in the present paper, two inverse techniques are proposed: the first is the multilevel identification method based on the simplex optimisation algorithm and the second one is based on the genetic algorithm. These methods are used of the physical parameters of a simulated case of a porous material located in a duct by the computation of its acoustic transfer, scattering, and power attenuation. The results obtained by these methods are compared and discussed to choose the more efficient one
