2. Line Balancing
 Balancing Of Machine
 An assembly line consists of several working
stations at which different operations are
performed.

3. Assembly Line Balancing
 Line Balancing is an effective tool to increase the
output of the Assembly line and to reduce manpower
and cost. Henry Ford who introduced the Assembly
Line Balancing and in early times it was simple line
balancing (LB) which has optimized the industrial
importance, the effective difference between the
optimal and sub-optimal operation can afford savings
which will be million dollars every year.

4. Line Balancing
 It is a Classical Operation Research (OR)
which optimizes the problem, and it has been
handled by OR for many decades. Many of
the algorithms have been proposed to solve
this problem. Its a commercial software which
is available to optimize the industry and their
lines.

5. Models
 Assembly Line Balancing is dependent on 3
models and it is described that these 3 kinds
of models is related to Assembly Line
Balancing and they are Single-Model
Assembly lines, mixed models, and multi-model
Assembly lines.

6. Single Model Assembly
 Singe-Model Assembly Line: in early times assembly
lines were used in high level production of a single
product. But now the products will attract customers
without any difference and allows the profitable
utilization of Assembly Lines. An advanced technology
of production which enables the automated setup of
operations and it is negotiated time and money. Once
the product is assembled in the same line and it won’t
variant the setup or significant setup and it’s time that is
used, this assembly system is called as Single Model
Line.

7. Mixed Model Assembly
 In this model the setup time between the
models would be decreased sufficiently and
enough to be ignored. So this internal mixed
model determines the assembled on the
same line. And the type of assembly line in
which workers work in different models of a
product in the same assembly line is called
Mixed Assembly Line.

8. Multi-Model Assembly
 In this model the uniformity of the assembled
products and the production system is not that
much sufficient to accept the enabling of the
product and the production levels. To reduce
the time and money this assembly is arranged
in batches, and this allows the short term lot-sizing
issues which made in groups of the
models to batches and the result will be on
the assembly levels.

9. Assembly Line Balancing
The purpose of the assembly line balancing technique
is:
1. To equalize the work load among the assemblers
2. To identify the bottleneck operation
3. To establish the speed of the assembly line
4. To determine the number of workstations
5. To determine the labor cost of assembly and pack out
6. To establish the percentage workload of each
operator
7. To assist in plant layout
8. To reduce production cost

10. Capacity Planning
Decision

11. Capacity Planning Decision
 Capacity – What should be the output
 Capacity Planning – It is the process of
determining short term and long term needs
of the organization.
 Long Term
 Short Term

12. Applications
 It helps in estimating the total sum and
requirement.
 Total Machine and labor requirement.
 System Availability
 Resource Availability
 Helps in process mapping and capacity
analysis

13. Labor Requirement
 Labor requirement = (D*S) / E

14. System Availability
 System Availability = N * h

15. Types of Decisions
 Strategic Decisions
 Tactical Decisions
 Operational Decisions
