The Industry 4.0 era sees the manufacturing industry on a steady march towards smart manufacturing. This high-tech revolution—involving technologies like Internet of Things (IoT), Robotic Process Automation (RPA), and Artificial Intelligence (AI)—may be the solution for manufacturing to thrive amidst perennial challenges such as manpower shortages.
For example, with ubiquitous IoT devices feeding data from machines, technicians and operators spend less time and energy physically going back and forth from machine to machine. Each person can now man more machines, and can even do so remotely.
But signals and data need to be analysed before they can become useful. This is where RPA and AI come in.
Role of RPA in Industry 4.0
RPA helps to link dispersed, disconnected devices together—it can be used to automatically and quickly fetch data from disparate systems and link them together, for example in the ERP system or by creating reports. By incorporating AI capabilities, RPA can also automate data analysis and some cognitive decision-making. RPA can also be used to automatically trigger actions.
RPA eliminates Lean Manufacturing wastes
RPA helps manufacturers become more lean, agile, and productive. In fact, RPA helps eliminate several aspects of the 8 wastes of lean manufacturing. For example:
Automating the generation of Bill of Materials (BOM) cuts down the wastes of waiting and defects. It reduces errors and the amount of time spent, thus resulting in shorter time-to-market and less waste or rework.
Automating stock item reordering cuts down waiting and inventory because it results in a shorter internal reaction time and consequently lower buffer stock levels.
Cutting down manual processes frees up workers’ time from mundane tasks (cuts down under-utilisation of talent), and allows better use of their expertise.
Benefits of RPA in Smart Manufacturing
Better decisions through better data
Large volumes of data, processed automatically and quickly through RPA and AI, can give never-before-seen insights that provide a more complete picture and help the management make better decisions—more accurate production planning, capacity planning, and more.
Reduced reliance on manpower
Each staff member, both technical and non-technical, can now do more—man more machines, analyse more processes, process more transactions—since they don't have to do as much mundane, repetitive work like manually copying and pasting data, compiling reports, etc.
Agile and responsive to changes
By automating data processing with RPA, companies can detect changes in real-time—be it shop-floor conditions, customer demand, or changes in supply—and take corrective actions, fast.
I have been working with the CFB Bots since the dawn of this year. They came recommended by UiPath.
From the get-go of our enterprise implementation, they were very helpful. Regardless of whether it was part of the engagement scope or not they have been very prompt to aid and in response.
Special thanks and shout out to Siyong & Tony for making our maiden voyage into RPA a smooth sail.

RPA Use Cases in Manufacturing
RPA can monitor customer demand, inventory levels, and production capacity in real-time and reorder items with low stock level, reducing reaction time to changes in customer demands. Digitising paperwork and automating procurement processes—sourcing, RFQs, evaluation, reporting, and more—also result in more optimum inventory levels.
Bill of Materials (BoM)
Because of its detailed nature, preparing the BoM is tedious, time-consuming, and highly prone to error—and any error can cause rework, delays in shipment, and even massive loss to the company.
RPA can automate the preparation of the BoM, getting it done in less time and with higher accuracy. Besides, by deploying RPA bots to also monitor the actual consumption of the items, the BoM can be updated in real-time and grow more accurate with time.

Production Floor Administration & Reporting
RPA can help automate administration and reporting work to achieve more accurate results in less time. For example, RPA bots can make changes to staff and machine allocations based on pre-defined triggers, or automatically generate regular reports across different factories for analysis and decision-making by the management.
Production Floor Administration & Reporting
Communicating with hundreds of vendors and maintaining vendor master data are gargantuan tasks that are highly manual and error-prone.
RPA can automate the bulk of this manual work—creation of vendor records, checking vendor documents, checking for duplications across different entities, GST and ACRA validations, and more—eliminating human error and drastically reducing resources needed.
Preparing inspection reports is an inefficient and time-consuming task, and delays in preparing these reports negatively impact the management's ability to intervene in a timely manner to ensure compliance.
RPA bots can prepare and disseminate reports in minutes or seconds, enabling swift actions to be taken. They also leave audit-ready trails so you don't have to scramble to prepare information for regulatory audits.
