What is IE fundamental?
The basic to do IE
Basically: a science of operations
The main criteria:
– Quality
– Timeliness
– Cost
IE ensures that the goods and/or
services are provided at the right
quality at the right time at the right
cost
Right means: effective and efficient
Combinations of soft (management) and
hard (engineering) sciences
Science vs intuition (1)
Looks like spinning
We sure that these
are fixed because
the grids help us to
measure the position
Science vs intuition (2)

Operations
A job or task, part of an activity, consisting
several work elements

Why do we need to know about
“Operation”?
Production System essentially is the sum
of its individual operations
Why we concern on quality, timeliness, and cost?
Technology: advanced
technology and Internet
Customers: have a greater expectation
– I need the product to be delivered
on time
– I need mobile phone that has
many features, etc
Competitor: intense
competition
Organizations winning the competition on above criteria
will be survived

The main aim of any industry is
Relationship between Production
System – Effective & Efficient
to produce an item (or service)
to sell at a profit.
continue business = continue
profit
How can it be reached?
an industry needs to become
effective in whatever it does.

Let’s watch a short movie
Note and discuss:
– The analysis activities
– The design activities
– The control activities
– The management activities
3 fungsi dasar pada suatu system
terpadu yang terdiri dari 5m, 1 I, 2 e:
1. Fungsi Manufacturing –membuat
produk
- ---untuk industry jasa –
menyediakan jasa
2. Sales – menjual produk / jasa
3. Finance dan accounting
Berarti pada saat kita membahas
tentang fundamental of IE, maka kita
harus mengkaitkan fundamental of IE
tadi dengan ke-3 fungsi dasar pada
suatu perusahaan + humam
resource management
Fundamentals
of IE
Operations
analysis,
design, planning
Analysis  to find
the opportunity of
improvement
Design  to
develop the system,
based on analysis
Operations
control
Operations
management
Control  to make
sure that the
system performs as
well as the design
Management  to
organize and
synchronize all
parts of the system
Operations analysis and design
Method engineering
Work measurement
Ergonomics
Facilities planning and design
Material handling
Quality Planning
*fungsi manufacturing
Production Planning
Inventory Planning

Operations management
Team based
Continuous improvement
Operations analysis and
design
Method engineering
Principle: to make a production system efficient,
we have to make sure that the individual
operations are efficient
Done by analysis and design on:
– value added and non-value added activities (OPC,
motion and time study, etc.)
– combination and timing of activities (human-machine
chart, left-hand right-hand chart, crew chart, gang
chart, etc.)
– synchronization (eg.: DFM, DFA)
Highlighted: timeliness and cost
Work measurement
Principle: performance could only be
measured by developing the standard
Done by analysis and design on:
– the time required to do the job
– the time required for allowance (personal
time, fatigue, unavoidable delay)
– the normal time
– the standard time
Highlighted: timeliness and cost
Ergonomics
Principle:
process/machine/equipment/method must
be match with human
Done by analysis and design on:
– human selection
– process/machine/equipment/method design
(skeletal/muscular, sensory, environmental,
mental)
Highlighted: quality and cost
Facilities planning and design
Principle: proper location, arrangement, and size
of facilities will minimize the total cost
Done by analysis and design on:
– geographical location of factory
– layout of facilities within factory (plant, water, tower,
office, warehouse, power plant, etc.)
– space grouping within facilities (departments
arrangement)
– equipments arrangement within groups
Highlighted: timeliness and cost
Material handling
Principle: the best material handling is no
material handling
Done by analysis and design on:
– the recent material handling
– the possible reduction of material handling
– the possible integration of material handling
and value added activities
Highlighted: cost
Operations control
Production control
Goal: to make sure that the production
process provide the right production
quantity at the right place and at the right
time as planned
Concerns:
– WIP
– Line balancing
– Due date
Highlighted: timeliness and cost
Inventory control
Goal: to make sure that the inventories are
available at the right quantity at the right
place at the right time as required
Concerns: trade-off between setup cost
and holding cost
Highlighted: timeliness and cost
Quality control
Goal: to make sure that the quality is met
the standard
Concerns
– inspection
– root cause analysis
– process improvement
Highlighted: quality and cost
Operations management
Team based
Management must performed by a team,
to control over process improvements,
plans, and goals
Examples:
– Production management
– Quality management
– Information management
– Human resources management
Continuous improvement
Incremental (may be
partial) improvement,
based on control and
analysis
Give examples…!
