Planning in production systems

1. Slovak University of Technology Faculty of Material Science and Technology in Trnava Planning in production systems Production processes, types of productions

2. Production processes • are processes which transform inputs to outputs • individual production processes are different from dependency on different characteristic • are organized by different approach

3. Production in aspect of amount of produced goods: • piece production • serial production • short-run production • medium-run production • long-run production • mass production

4. Types of production

5. Organization of production process and current of production • Organization of production process production process (PP) is working on parallel places and in parallel time  have to co-ordinate (organize) it.

6. Organization part of PP • Area part: • co-ordination individual factors in area – area structure (organization of workplaces and material current) • area structure basic element - workplace • co-ordination and workplaces grouping is influenced by specialization of production array • Time part: • bilateral co-ordination individual operation PP – time structure PP (time knot, advance accounting )

7. Basic workplaces class • by the degree of specialization – workplaces in • piece production • serial production • mass production • by the degree of work technical evaluation • hand • machine - hand • machine • automated • robotic • by the number of workers on workplace • individual • group • more machinery

8. Basic factors which influence area production organization • general factory • communication network • buildings character • engineering networks • type of production • in-plant specialization • operating equipment • technological method of making goods

9. Type of workplacesco-ordination • technological co-ordination • objective co-ordination • composite co-ordination • stationary co-ordination • individuálne usporiadanie • individual co-ordination

10. Basic factors which influence time structure of production process • length of technological operations • charges amount • approach delivery of charges pieces • approach accession of producing device • technological factors • workers qualification • length of transporting ways • speed of operating equipment • time of control operations • time of breaks • level of production management

11. Continuous producing time - time interval, which elapsed from first operation goods setting to ending last operation and delivery it to store Production charge - number of pieces, which are non-stop dressed on one workplace with one-shot time uses for constructing this workplace

12. Transporting length - number of pieces, which are transporting together from one workplace to other Executing charge - number of pieces, which are use for doing i-operation in one step

13. Production organization increases changes • transporting center of production organization from production process to organization background area and production operating • mathematics models application and models for resolution placement problems • change to higher production types • uses organization flexibility of production process

14. Factors, which influence organization production forms • - production type • - goods character • - technology and technique level

15. Organization production process form • Phase form (for short-run production, is here technological workplace co-ordination) • Current form (for long-run and mass production) • Group form (serial, short-run production) • Cell (star) form (rise by combination phase and group characteristic) • Constructing form (for piece production)

16. Forms of employment NC • individual • group – in real closed group 3-5 machines, in which accomplish close working circle – cells (nest) • production system - integrated production parts from NC machines, production groups designed and technological similar parts
