Building a Smart Factory MES: Production Planning and Shop-Floor Execution in Electronics and SMT Manufacturing
For manufacturers preparing for a smart factory, this guide outlines the role of MES, the sequence for connecting production planning and materials with the shop floor, and the data to verify before implementation.
What role does MES play in building a smart factory?
MES is a manufacturing execution system that verifies how work orders are carried out on the shop floor and connects process, quality, equipment, and production performance data. A factory does not operate simply by connecting equipment. Plans and material preparation must match actual working conditions for shop-floor data to support decision-making.
Prepare with MPS and MRP, then verify execution with MES
First, use MPS to set the products and timing for production, then use MRP to compare the BOM, inventory, and scheduled receipts to identify material shortages and when they are needed. E-MPS process-level plans assess execution feasibility through CRP, equipment availability, and workforce management. MES feeds execution results back into planning through operator interaction, error-preventing poka-yoke, and traceability that connects records.
What should electronics and SMT manufacturers check first?
First, verify the standards for items and BOMs, when material substitutions and changes take effect, and how process-level work orders connect to production results. Then determine how equipment and inspection data will be collected and what operators must actually enter. Distinguishing data that can be collected automatically from data requiring shop-floor verification helps reduce duplicate entries and omissions.
Materials to Prepare Before Implementation
Prepare the BOM for representative products, production plans, material inventory and scheduled receipts, process routes, available working hours by equipment, and current daily work reports to identify where the flow breaks down. Rather than changing every process at once, you can first validate the connection between planning and results in a representative process and then determine the scope for expansion.
Scope to Review with CMC TECH
From the perspective of integrated information systems for manufacturing companies, CMC TECH reviews the connection between CMC-MES and production planning and materials management. While the explanation focuses on the requirements of electronics and SMT, semiconductor, and semiconductor equipment manufacturing, the applicable scope for other manufacturing industries can also be discussed based on their process and data conditions.
