System lifecycle

As sketched out initially, simulation can be used at different points in time of a production system lifecycle and with a different scope (see Figure 2.1). Considering the lifecycle and the scope, the three case studies described in this section may be classified differently, from supply chain to plant level and from planning to daily operation. 

Evidence for S/W or hardware verification activities performed by system lifecycle processes. 

Traceability between the requirements at a particular stage of the system lifecycle. 

Traceability of changing or changed requirements throughout the system lifecycle for better change management. Such requirements can be defined as a sub-tree of a tree of traceable requirements, or a sub-tree of a set of traceable trees. 

Adoption of the principle that product, process, and system lifecycle development and deployment—Conceiving-Designing-Implementing-Operating—are the context for engineering education. 

Rationale for adopting a lifecycle model as the context. The rationale for adopting the principle that the system lifecycle—conceiving, designing, implementing and operating— is the appropriate context for engineering education is... 

UK-SPEC does not reflect the need for competence in all aspects of the product or system lifecycle. The implementation and operational phases, in particular, are not addressed by appropriate learning outcomes. 

However, it could also be argued that CDIO is already fundamentally aligned with the ideas of sustainability engineers are said to conceive, design, implement and operate complex technical systems with the entire product/process/system lifecycle in mind. Moreover, sustainability is a complex concept It includes three main dimensions economic, environmental, and social sustainability, including both subject matter and judgmental aspects, such as, ethics and decision-making [14]. There are many places in the CDIO Syllabus that emphasize the lifecycle perspective, for example, requirements should cover aU phases of the lifecycle analyses should be made of lifecycle values and costs and product retirement should be planned ahead. With this broader perspective in mind, links between sustainability principles and CDIO Syllabus topics can be identified [15].

An important advance in KBE research has been made by the ESPRIT Framework IV Methodology and tools Oriented to Knowledge-based Applications (MOKA) project which ran from 1998 to 2002. The MOKA project was the first to identify a clear lifecycle for KBE systems and applications, consisting of eight steps. The KBE System Lifecycle is a process view of the lifecycle stages of a KBE system. The first stages (Identify Justify) have the purpose to identify, analyse and... 

In this paper, we present an approach to perform software changes in the operation and maintenance phase of the systems lifecycle. Changes are performed dynamically, by replacing parts of software (i.e., software components) with their functionally equal out-of-the-box instances. In order to prevent the impact of changes on systems integrity, we provide a support to model and to analyze the system. The main outcome here is that specific kind of changes can be maintained without adding any development costs. 

The safety engineering phases correlates with the pre operational phases whilst the safety management phase correlates with the applieation and maintenanee aspects of the system lifecycle. Although the Safety... 

For each option, all of the classes listed in Table 4-10 above were reviewed in order to identify the high level safety, RAM and environment protection requirements and benefits. The analysis was focused on identifying only those requirements that are not covered by existing Polish standards, for each class. During the review, the basic stages of the system lifecycle were considered ... 

In summary, the current considerations in Industrie 4.0 require that information processing has to be enhanced toward a semantically integrated approach, which allows data analysis on data coming both from product and production system lifecycle processes. In production system engineering, the current focus on data processing has to be moved on to information processing of semantically enriched data.
