Line Balancing & Capacity Planning Decision

Line Balancing Balancing Of Machine An assembly line consists of several

working stations at which different operations are performed.

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.

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.

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.

Single Model Assembly 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.

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.

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.

Assembly Line BalancingThe 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

Capacity Planning

Capacity Planning 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

Capacity Planning Capacity Productive Capacity Strategic Capacity Planning Capacity Used Best Operating Level Capacity Utilization rate

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

Labor Requirement

Labor requirement = (D*S) / E

System Availability

System Availability = N * h
