Discussion

  • Types of complexity:
    • Market
    • Product
    • Organization
    • Process
    • others?
  • Managers typically don’t understand complexity
    • Growing impact and importance
    • Managing complexity can be a competitive advantage (in business, military, health care, etc)
  • Complexity results from dependencies within system and relation to environment and other systems
    • Some emerging approaches based on system structures
  • Objective: Better tools and methods for analysis, control, optimization of complex products/systems

Some methods available already: QFD, Graph theory, DSM, DMM, MDM

  • Premise: complexity is found in structures (form of complexity regarded here); better methods to plan structures will help


Results

During the workshop, besides, the initial presentations, different uses of dependency models, different models and the interest to apply these models were discussed.

Fields of research

As fields of research, these topics were collected (documentation):

  • Definition of complexity
  • Understand problems related to complexity: what is "the essence" to understand complexity?
    • Taxonomy / classification
    • Representation of relevant parameters
    • Assumptions and their implications to understanding models of complexity
  • Subjectivity of structures
    • deterministric
    • stochastic
    • ...
  • Uncertainty
  • Interaction with Systems
  • Data acquisition
    • Integration with engineering workflow
  • Interfaces
  • Decomposition

Applications of structure and dependency modeling

As applications of dependency modeling, the following items were collected (documentation):

  • Product architectures
    • Modularity and product family/platform design
    • Product family management, modularity and variety management
    • Product-service systems
    • Refurbishment
    • Analysis of mechatronic products
    • Mass customization
  • Requirements management – network of interacting requirements
    • Functional complexity – system architecting
    • Set-based design approach to parallel solutions
    • Target costing and complexity of other holistic requirements
  • Organization design
    • Analysis of the underlying organization
    • Alignment of product architecture and (Process) organization
    • Design chain management – which suppliers develop each component, how to cope with outsourcing
    • Outsourcing to suppliers
    • Which technical domains required for each component development
  • Process improvement
    • Coordination risk in distributed development
    • Multiproject management
    • Multi-project landscapes / highly-distributed competencies scheduling
  • Change propagation in networks
    • Change management & change propagation
  • Interdependent models in design
  • User perspectives
    • Users/actors vs. models in design
    • Participation of users in design
    • Customer demands / requirements and interdependencies with the product structure
  • Technology lifecycles
  • Difficulties in modeling complexity
    • Global interaction with models
    • Automated data collection
  • Optimization
    • Parameters and scenarios / Trade offs
    • Hard and soft parameters
  • Coordination in processes

Modeling Methods

As modeling methods, these were collected (documentation):

  • General dependency models
    • DSM
  • Dynamic models
    • System Dynamics
    • Discrete event simulation
  • Quantitative models
    • Choosing by advantages
    • Trade spaces
    • Representation or rationale
  • Other Aspects
    • Visualization
    • Indexing
    • Metrics

SIG Organization

Last, organization was discussed, and the following topics were designated as interesting (documentation):

  • SIG as an opportunity to work on the topic of complex structures
  • Documentation of results of the workshop is sent via e-mail
  • Possibility to use DSM homepage – included features:
    • Tutorials (please send extensions to be included)
    • Use-cases (please send extensions to be included)
    • Publications (enhanced search functionality in development)
    • Description of methods
    • Links to institutes and partners (please send your address to be included)
    • Tools
    • DSM-Wiki (please feel free to change, add, enhance)
    • DSMweb.org is used as a forum for communication
  • Announcements:
  • Suggestion for next meeting:
    • the next SIG meeting is held at the Design Conference
    • Presentations from different participants on their models, perspectives and approaches enhanced understanding of the overall term complexity
  • on the long run, a common example that shows different methods and their use is to be generated
  • the DSM Conference is an event that is supported by the SIG, representing much of its work

Next steps

Back to SIG Managing Structural Complexity.

  • SIG meeting at Design Conference in Dubrovnik
  • Set up of homepage as part of DSMweb.org
