2. SCHEDULING
• Scheduling is an important tool
or manufacturing and engineering, where it can
have a major impact on the productivity of a
process.
• Scheduling relates to the timing of each individual
delivery.
• It mainly deals with handling application.
• It increases efficiency of production.
• Scheduling decreases material handling cost and
waiting time for work in process.
3. SCHEDULING
• It co-ordinate man, machine and production
facility for obtaining higher output.
• It uses graphical data plotted by taking
readings to identify the errors in process
• Corrective actions are taken and
manufacturing lead time is minimized
• Scheduling is the study of process and
organizing them to obtain higher effficiency
4. Advantages of Scheduling
• Process change-over reduction
• Inventory reduction, leveling
• Reduced scheduling effort
• Increased production efficiency
• Labor load leveling
• Accurate delivery date quotes
• Real time information
5. KNOWLEDGE BASED SCHEDULING
• A general knowledge-based system consists of
three components:
– a database
– a knowledge base
– an inference engine
6. • The database stores declarative knowledge
about the goals, the current situation of the
world, and the semi finished plan.
• The knowledge-base stores the domain-specific
and procedural knowledge, often represented
by production rules or operators.
• the inference engine stores control knowledge
indicating how to select operators and when to
apply them.
7. KNOWLEDGE-BASED SCHEDULER CAN
PERFORM THE FOLLOWING TYPES OF
SCHEDULING FUNCTIONS:
1. Adaptive scheduling: Schedules are
generated by goal-driven procedures; the
scheduler can perform dynamic scheduling to
adapt to changes in the FMS environment.
2. Planning: State-space inference and heuristic
search are used to derive production
processes.
8. 3. Optimizing: Simulation and selection of plans
from alternates are done by evaluating
performance criteria and heuristics.
4. Learning: Recognition, refinement, encoding,
and integration of processes are performed
to enhance the scheduling performance.

10. COMPUTER HIERARCHY CONTROL
• The term computer hierarchy control is used
to describe such configuration which consist
of following components.
– Multiple process control station located
throughout the plant to control the individual loop
and device of the process.
11. – A certain control room equipped with the
operator stations where supervisory control of
plant occurs
– All process and operator stations interact with
each other by means of communication network.

13. SUPERVISORY CONTROL
• The term supervisory control is usually associated
with the process industries, but the concept
applies equally well to discrete manufacturing
automation.
• Supervisory control represent a higher level of
control than DDC, NC & PLCs.
• Supervisory control denotes a control system
that manage the activities of a number of
integrated units operations to achieve certain
economic objectives for the process.
14. • Supervisory control is not much more than
regulatory control or feed forward control.
• In other application the supervisory control
system is designed to implement optimal or
adaptive control.
• Supervisory control can be defined as the
control system that directs and co-ordinates
the activities of several interacting pieces of
equipment in manufacturing cell or system.
