Linking modularity with problem solving and coordination efforts

Abstract: We explore the relationship between process architecture decisions, problem solving and coordination efforts during distributed product development, ie, when development work is dispersed across organizational boundaries Process architecture refers to the manner in which the tasks and interfaces within a project are organized so that a project can be executed in an efficient manner The theoretical foundation for our investigation draws upon the information processing (IP) view of product development and transaction cost economics The IP view calls for manipulation of the architecture by making problem-solving tasks modular, such that reducing task interdependencies minimizes the development time The transaction cost view calls for transactional efficiency, for example, reduction in the coordination burden for each productive task We present several measures of modularity based on a design structure matrix (DSM) mapping of the development task structure Then, we analyze the relation between these measures and transactional efficacy and task completion times Our empirical evidence comes from 71 tasks carried out in 11 software development projects Data analyses show that the improvement in the transactional efficacy is associated with increase in task modularity Our results establish that increasing modularity reduces the development time and the coordination effort However, these results also suggest trade-offs: modularity measures do not contribute equally to this gain in efficiency and increasing modularity is negatively associated with the technical problem-solving efforts Copyright # 2008 John Wiley & Sons, Ltd

Modeling, validation and software implementation of production systems using high level Petri nets

Abstract: This paper discusses the design of the coordination subsystem of a Flexible Manufacturing System (FMS) and its integration into the integrated control system of the FMS. The approach adopted is based on the use of high level Petri nets (colored Petri nets) for the subsystem modeling, its qualitative and quantitative analysis and its software implementation. The design of the real time scheduling subsystem as an expert system is proposed. The interaction between the coordination subsystem and the local controllers and the scheduling subsystem is done by using a terminology based on the colors of the coordination model.

FUNSOFT nets: a Petri-net based software process modeling language

Abstract: Introduces an approach to software process modeling and analysis. It is based on describing software processes by FUNSOFT nets. FUNSOFT nets are high level Petri nets which are adapted to the application domain of software process modeling. Their semantics is defined by predicate/transition nets. That enables them to benefit from standard analysis techniques approved for predicate/transition nets. >

Automated Certification for Compliant Cloud-based Business Processes

Abstract: A key problem in the deployment of large-scale, reliable cloud computing concerns the difficulty to certify the compliance of business processes operating in the cloud. Standard audit procedures such as SAS-70 and SAS-117 are hard to conduct for cloud-based processes. The paper proposes a novel approach to certify the compliance of business processes with regulatory requirements. The approach translates process models into their corresponding Petri net representations and checks them against requirements also expressed in this formalism. Being based on Petri nets, the approach provides well-founded evidence on adherence and, in case of noncompliance, indicates the possible vulnerabilities.
