Why Automation is Beneficial for Lean Manufacturing?
Manufacturing automation and lean manufacturing share a common objective: satisfying customers while minimising costs through focusing on eliminating low-value or non-value activities, cutting waste, and ensuring consistent quality. However, blending these two can be challenging for even experienced manufacturing experts. Let’s explore several advantages that harness the synergies between automation and lean manufacturing.
Reducing waste
Automation is a great way to cut waste. Well-set-up machines make parts accurately and can warn if things go off track, preventing mistakes and the need for rework – both critical issues in lean manufacturing. Automation is especially efficient for routine tasks where even skilled operators cannot match their precision. Plus, it reduces wasted effort in two ways:
- Many automated machines can do multiple tasks, so there is no need to move materials around.
- When a task is done, automated machines can move materials to the warehouse or the next step without needing people to step in.
Internet of Things (IoT)
Linking equipment to business systems simplifies reporting production status. IoT eliminates the manual reporting of task completion, scrap, or material usage for accounting and inventory systems. This allows operators to concentrate on more valuable tasks to meet customer demands.
Improving accuracy
Inventory management is vital in manufacturing, yet it can be inefficient. To serve customers effectively, precise inventory control is essential. One way to achieve this is by automating the picking and storing of items. Automation reduces the chances of losing or misplacing materials and ensures accurate tracking, minimising waste from expired or spoiled items.
Enhancing safety
The implementation of warehouse automation can enhance employee safety, as most workers will have fewer reasons to enter the automated storage and retrieval system (AS/RS) zone or walk through the warehouse, except for maintenance purposes. Consequently, the likelihood of falls in an automated warehouse is likely to decrease.
Ways to Identify Opportunities to Implement Lean Automation
Approximately 69.7% of manufacturers use various lean practices. Some of these lean methods are more challenging to implement than others, but all of them demand at least a moderate level of effort. Nevertheless, it’s crucial not to ignore the significant advantages they can bring in a competitive landscape.
However, investing in lean automation may entail expenses, it’s important to note that it is not a universal solution. Consequently, it is crucial to pinpoint the specific areas within your warehouse that will reap the most benefits.
You can achieve this through the PDCA model, which consists of four distinct steps: Plan, Do, Check, and Act. This model offers a straightforward and efficient method for problem-solving and change management.
Let’s delve into how you can leverage this model to identify opportunities for implementing lean automation:
Step One: Planning
To begin, take the time to identify areas within your warehouse that require improvement and determine the most suitable solutions to address these issues.
For instance, if your warehouse encounters challenges related to picking errors, consider investing in software solutions like a stock management system.
Once you have formulated a plan, it’s time to initiate the next phase: taking action.
Step Two: Do
Now that you have pinpointed the warehouse areas suitable for lean automation, it’s time to put your chosen solutions into action. Keep in mind that challenges may emerge during this phase, so consider starting with a limited-scale implementation in a controlled setting.
For instance, you can begin by implementing a stock management system in one specific section of your warehouse. As an example, you might decide to test the solution in your picking area once or twice a week to gauge its effectiveness.
Step Three: Check
This step is crucial and must not be overlooked. In the evaluation stage, you will need to assess the implementation of your plan to determine its effectiveness.
If you observe a significant reduction in picking errors, it’s evident that the solution is effective and may warrant further investment on a larger scale. However, if picking errors persist at the same level, it may indicate that the type of automation you introduced may not be the right fit for your needs.
Collaboration with your team is vital during this phase. Request feedback to identify any issues and ascertain whether the automated solution has enhanced operations.
Step Four: Act
In the last phase, make a decision on whether to invest in the automated solution or explore alternative options. If you opt for a different approach, repeat the process. This repetitive method enables your team to identify, test, and enhance solutions, creating an ongoing cycle focused on waste reduction.
