Future
Complex products like the investigated wheeled excavator are characterized by a large number of
constituent parts, complex processes and - referring to the product life cycle - a dominance of the usage
phase because of high fuel consumption throughout a long usage phase. Regarding the life cycle an ecoperformance analysis helps to identify environmental key factors and cost drivers in a static view.
How will business processes develop in terms of digitization, interdisciplinarity, integration and collaboration? How will today’s
challenges of a modern, interdisciplinary, and integrated development of smart product systems and services be overcome? Is Industrial
Internet (incl. Industry 4.0 and the Internet of Things and Services) still the central megatrend from the engineering perspective? And
when real and virtual world merge, will digitization allow for innovations towards sustainable economy?

System Lifecycle Management (SysLM) is an integrated, information-driven concept to improve the performance of a product system over
the entire lifecycle. It achieves efficiency by using a shared information core system that helps engineers to efficiently manage
complexity in the life cycle from first definition of requirements to end-of-life activities. Thus, the concept does not provide innovative
systems but can contribute to engineering at administrative level by providing the right information at the right time in the right context.

1. Objective
3. Approach
ERMA Research Motivation
• In the field of construction equipment with well-established, mechanical,
hydraulic, hybrid and electronic solutions, the need of eco-design will raise
significantly because of further increase of energy costs, stricter requirements and
growing competitive pressure. ERMA requires analysis of the wheeled excavator
and the application of Life Cycle Assessment in a proactive manner supporting the
product development.
• Extensive concepts and new structures such as innovative and integrated
technical solutions for increasing the total energy efficiency are needed. New
requirements on the product’s sustainability and eco-performance as well as the
demand for high flexibility lead to complex product systems, which contain
mechanic, hydraulic, electric and even hybrid subsystems.
• The results shown are based on an exemplary product structure, related manufacturing, transportation and distribution processes as well as on an assumption
for the usage phase. Regarding the life cycle, more than 90% of the greenhouse
gas emissions are resulting from energy consumption during the usage phase.

Industrieller Fokus
Challenges for a more sustainable
development process are:
•
•
Multi-disciplinary view on complex product systems:
Current development processes of complex mechatronic
products are heavily influenced by multiple disciplines like
mechanic, electronic and informatics as well as dependencies
between information elements and engineered system parts.
System specification, modeling and first simulations are still
discipline-specific.
5. Consideration of the Early Lifecycle Phase
Methodology to Include Behavior in the Early Development Phases

Behavior in the Early Development Phases
Step 1 - Identification of key drivers following the RFLP-approach
Step 2 - Specification of behavior artifacts in the early design phase
Step 3 - Analysis of behavior artifacts in the early phase
Step 4 - Requirement traceability, verification and validation
Step 5 - Interpretation and visualization of the results
Extended V-Model for Multi-Disciplinary Product Development
(Based on VDI 2206)
Life cycle view on complex product systems:
Beside the assessment of the used materials based on the
product structure, a comprehensive consideration of all related
processes – starting from raw material extraction to end-of-life
activities as well as all supporting processes like transportation
– are of central importance in regard to sustainability.
An approach based on methods of Model-Based Systems Engineering
can help to improve traceability within complex multi-disciplinary
systems throughout multiple lifecycle phases and thereby to identify
key areas to be targeted by an exemplary case scenario of the
sustainable development process of a product system.

4. Merge of Real and Virtual World
2. Related Work
In order to introduce an approach, the described theses build upon the previous work on sustainability assessment and research on
the topic of Model-Based Systems Engineering performed at the Institute VPE // University of Kaiserslautern, Germany.
Sustainable Development
The specification of the system, modeled by structure elements in the early design phase is
too coarse for a detailed assessment that can support the engineering eco-design. It is
important to take the usage phase into account already in the early design phase and to
provide traceability between the requirements of the product.
Model Based Systems Engineering
Design for Environment will not be sufficient for all times. In future all three
dimensions of sustainability will have to be considered.
