Production
Production is the directed use of goods and services (production factors) to
extract resources, manufacture or assemble goods or create services. The
direction of this use is done by planning, organisation, control and supervision
of production, including the choice of means for achieving production goals.

Surplus value is created when the production attains additional value for the
customer
Profits are attained when surplus values generate higher revenue than the sum
of variable and fixed expenses of the production process
➔ Goal: Raising the surplus value for customers and reducing production costs
Magic Triangle
◼ Balance between costs, time and quality
◼ Distribution of the total investment of 100%
Time to Market → High costs, low quality
◼
Minimization of effort → Time investment, low quality
◼
High product value → Time investment, high quality

◼ General life cycle for products of all kinds
◼ A company has multiple products in different phases of the PLC
◼ Development of a new product
Changing of parameters in the current assembly line
◼
Redesign of the current assembly line
◼
Construction or expansion of an assembly line
◼
Construction of a new factory
◼
◼ Factories and assembly lines are „products“ as well and follow the same life

Production complexity
◼ Trend towards more complex products
◼ Today
Variant management in order to address a large product portfolio
◼
Configurable assembly lines are required
◼
Demand of high flexibility in assembly (human and machine)
◼
◼ Digital information for assembly control becomes more and more important
Data about the current product's variant to be assembled
◼
Status of facility, suppliers, personnel
◼
Planning and management statistics
◼
Information about the surroundings for production planning (e.g.
◼
resource efficient production)
◼ Increasing demands in controlling facilities, assembly lines, factories,
suppliers and production itself
