For solving line balancing problems a number of methods are available, for example Heuristic , linear programming model, dynamic programming and comsoal (a computer method for sequencing operations for assembly lines). For intermittent flow system normally heuristic methods are preferred.
What are the main goals of line balancing?
The main objective of line balancing is to distribute the task evenly over the work station so that idle time to man of machine can be minimized [2] and to minimize total of idle time on the whole work station on a certain level of output [3] In general, the main purpose of line balancing is how to minimize the number ...
How do you solve a line balancing problem?

What are the steps in line balancing?
- Step 1: Understand the Takt Time. ...
- Step 2: Create a Process Top-down Chart. ...
- Step 3: Understand the Time Required for Process Activities. ...
- Step 4: Establish “As Is” Relationship: Takt Time vs.
Why balancing a production line is very important?
A balanced layout eliminates bottleneck operations and prevents the unnecessary duplication of equipment capacity. Line balancing is a major consideration in layout because imbalance can easily hinder the produc- tion .
How do you balance a work station?
- Outline your workstation sequence and draw a precedence diagram. ...
- Estimate the needed cycle time for each workstation. ...
- Calculate the hypothetical number of workstations you will need. ...
- Start assigning tasks to the workstations until the process times are equal.
What happens if line is unbalanced?
What happens if a line is unbalanced? Line Balancing is a strategy to level the workload across all processes in a workstation to remove excess capacity . It involves setting an optimal rate of production for required materials to meet within a particular time frame.
What is the goal of line balancing what happen if a line is unbalanced?
What happens if a line is unbalanced? The main goal of line balancing is to achieve a set of task groupings at workstations in the line that have equal time requirements to attain high utilization of labor and equipment . Unbalanced lines have bottlenecks at some workstations and idle time at others.
What is a balanced process?
Balanced processing refers to “ leaders who show that they objectively analyze all relevant data before coming to a decision “.
What is the first step in assembly line balancing?
The first step in balancing an assembly line is to specify the precedence relationships among tasks to be performed on the line . Having a lot of interstage storage of materials is considered a good layout design for a manufacturing plant.
What is cycle time in line balancing?
Cycle time is one of the important data for the line balancing at any production line. The time required to finish one product , or the total time takes before the product leaves the workstation and move to the next workstation is called cycle time.
What is the assembly line balancing?
Assembly Line Balancing (ALB) is the term commonly used to refer to the decision process of assigning tasks to workstations in a serial production system . The task consists of elemental operations required to convert raw material in to finished goods.
What is the assembly line balancing problem?
The assembly line balancing problem (ALBP) involves distributing the tasks needed to manufacture any unit of the products to be assembled among the work stations along a manufacturing line . It is usually assumed that the required tasks cannot be split, that is, each must each be performed at a single station.
Where is assembly line balancing used?
Assembly line balancing is mostly suitable in mass production conditions . Similar and repeated activities are grouped into workstations. Further workstations are balanced to have same cycle times. The assembly line balancing concept is is generally used for mass production.
How do you calculate delay in balance?
The balance delay is the percentage of wasted time or 100% – the efficiency. In this example, it is 4 (the idle time)/30 or . 1333, which is also determined by 1-. 8667.
