Design Of Production Systems Flashcards
A production system as a system
- a production system comprises all activities and resources needed in order to transform raw material into products
- A common way is to regard a production system with a holistic perspective
Holistic perspective
Also called “a system perspective” on production systems. It implies that systems should be designed with technical and physical parts, the humans in the system, and the way to organize the work, taken into consideration.
Functional perspective
inout/output system
Structural perspective
Different elements and their relation
Hierarchical perspective
sub systems as part of larger systems.
Design of production systems
Involves problem definition, identification of the goals, and to put forward different alternative solutions (problem solving). The result is a description of the production system to be (system solution).
Development of a production system
Includes besides the design of the system solution also the next stage, to implement the solution, which involves building and industrialisation of the product system.
Arguments for a process perspective on system development
- overlook functional borders to solve problems
- improve ability to meet the customer in a comprehensive manner
- prerequisite for learning, and development of knowledge.
Common activities in a design process
- Analysis
- Requirement specification
- Design or construction of subsystems
- integration of subsystems in totality
- ‘evaluation an decision.
Aspects affecting development of production systems
Actual options: Technology, work environment and organisation and planning and control
External influences: History, Trends, Globalisation and company structures
Strategies and fundamental attitudes: Management strategies, Production philosophies and company culture.
Industrial perspective
Trial-and-error
- Guess a suitable production system (i.e. guess values for an appropriate set of design variables)
- Evaluate the performance of the system. If it satisfies the performance requirements, then stop the design process otherwise return to step 1.
parts and elements of development framework
Planning: Management and control, structured way of working
Design and evaluation: preparatory design, Design specification
Implementation: Physical realisation, planning and start-up
Context and performance: Contextual aspects, production system performance.
Contextual aspects: Perspective and attitudes
Individuals, engagement, resource allocation to production engineering and product development, short-term vs long-term perspective, focus on output, a comprehensive view, separating means and ends.
Contextual aspects: Company preconditions
Market requirements, production’s role, company culture, management involvement.
Contextual aspects: Investmet considerations
Reasons for investing, investment decisions.
