Line balancing, an important process in production activities
Around us, there are still many businessmen who are still unfamiliar with the term line balancing. This term is still very rarely used on public occasions. This term will be very familiar to their ears whose daily has implemented a line balancing.
In general, line balancing is applied to the production process in the manufacturing industry, which line balancing has a very important role in ensuring the production is carried out following the target and also provides more benefits for the company.
Every company certainly wants to reduce production costs and also get a big one. This can be achieved by implementing a line balancing. So, we can say that Line Balancing is very useful in maximizing manufacturing interests significantly.
For this reason, every company and business people must be able to understand what is meant by line balancing and also the more profound benefits.
Balancing Line or Line Balancing is a production strategy in which includes balancing operators and also time on production machines in adjusting the production levels made. The main function is to make a production line that is quite flexible to minimize internal irregularities and external.
Type-type line balancing
There are two types of line balancing that are commonly used in the production process, namely Static Balance and Dynamic Balance.
- Static Balance
Line balancing with a type of static balance refers to differences in long-term capacity levels for several hours or more. This static imbalance will cause reduced use of machinery, workforce, and workstation.
- Dynamic Balance
In contrast to the previous type of line balancing, this dynamic balance refers to differences in short-term capacities, such as during minutes or the most maximum in a matter of hours.
Generally, this dynamic imbalance occurs because of changes in mixing between products and variations within the time of work that is not related to the combination of the production of different products.
That means this line balancing strategy is generally used for grouping facilities and existing tasks and labor in a more efficient pattern so that later it will be able to produce maximum or most potential balance of capacity and production flow in the assembly process.
These various tasks are grouped so that the total time used for the production process can be more efficient and able to reduce the empty time that can be used to produce more products or pursue targets faster.
In certain production lines, if the production time is the same as the time needed for a product, it must be produced so that it can meet customer demand, or commonly referred to as takt time, then this production line will be considered perfectly balanced.
If not, the resource possessed by the company must be able to be allocated or regulated so that it can eliminate or reduce congestion and also excess production capacity.
That means, the number of employees and the engine provided assignments for each task that must be completed in a predetermined production line must be balanced again so that the company can meet the maximum production level.
Benefits of Line Balancing
After we understand what is line balancing and also various types, we must also be able to know the benefits that must be generated from implementing a line balancing strategy in the production process carried out by the company.
In this case, there are at least four benefits that you can get from implementing a line balancing strategy in your production process, namely:
1. Reducing time waste
The waste of time is one of the eight types of waste or waste which are very often found in manufacturing companies. The waste, in this case, refers to the idle time that occurs when operational is not synchronized thoroughly.
For example, the waste of time that occurs when operator employees await the required production material or wait for other employees to complete their duties. Another example of waste this time also occurs when there is equipment that cannot be operated due to damage.
The application of this line balancing strategy can ensure that all operators and machines can work continuously. There are no more operators or machines that are burdened excessively or unemployed during working hours.
By minimizing the terminal time of the use of production machines, then Line Balancing can minimize the waste of time that should be maximized so that the production process can run more efficiently.
2. Reduce the supply of waste
Inventory waste or waste inventory is a waste or other waste which can be very easy to find in a manufacturing company.
In this case, the waste of the inventory in question is the occurrence of inefficacy in terms of allocating the capital owned by the company, such as the excess raw material, work in the process or item that is immature, and also the items that are cooked or ready for sale.
For this reason, the line balancing strategy will later equalize the standardization of production which in this case will be carried out to provide convenience in avoiding the buildup or the advantage of the inventory possessed by the company.
By reducing idle or empty time, then this line balancing will ensure that there is a minimum work that is indeed ongoing. Finally, by bringing the gap closer to production time and time takt, then line balancing can guarantee more timely delivery on consumers.
3. Absorb internal and external deviations
Other benefits of line balancing are being able to minimize variations contained in the production line carried out. Line balancing will allow the results of a more balanced, stable, and flexible production line to be able to adapt to existing changes.
As if the customer’s request is changing in terms of changes in a faster time, the production process can later be regulated faster by using line balancing.
The application of this strategy will also allow the company to predict the consequences of the changes brought to the production line concerned. Later the company will be much easier in modifying the path in adjusting the rate of production because it can make predictions.
How to Apply Line Balancing
1. Know Take Time Each workstation
The first stage contained in the line balancing is to understand takt time at each work post. You must know the level of customer’s request and also the time needed in completing a production process.
The formula that you can use to calculate takt time is as follows
T = TA: D
T = takt time
TA = Time Available
D = Demand.
2. Make process details
To be able to ensure a balance, you must be able to understand the linkages and also the order between various tasks in a process. Make details of the process of identifying relationships and also the order between various related processes.
3. Understand the time needed on each process activity
After completing the process details, we must be able to understand the time needed in each work post. Each of these details will be able to know the work time and also then summed into the total cycle time or total time in the cycle in the related work post.
4. Identify the workstation that has a difference
After successfully knowing the work time at each post, then you must identify which workers have a time difference with the set time cycle, whether it’s a higher time difference or a smaller time difference.
5. Analysis and do balancing actions
After successfully identifying the time difference with the time set, then do the balancing act of the workload so that the total cycle time at the work station concerned is lower than the time cycle of time.
6. Evaluation and monitoring of results
Each work post has been balanced in the process and its duties must be evaluated and monitored by each result.
Thus the explanation of us about line balancing. With the explanation above, it is expected that every manufacturing businessman can maximize its production process more efficiently, which will automatically lead to increased corporate profits.
