Key Differences Between Discrete and Process Manufacturing Software

Whether you’re managing a discrete or process manufacturing plant, software has likely become a crucial part of your overall production. Going digital using manufacturing software brings smart analytics that will help factories find efficiencies at every turn, helping you maximize throughput and produce more finished goods with less.

Discrete vs. Process Manufacturing

Though both can be complex, the differences between discrete and process manufacturing can be broken down into simple concepts.

What is discrete manufacturing?

Discrete manufacturing refers to the production of individual parts or units that come together to produce a final good, often in low volume. In this type of manufacturing, finished products are generally distinct items and can be counted as separate entities. In discrete manufacturing, products are typically produced through a series of specific and separate workflows or operations. Each item is often customized or made to order, and the production process involves assembling various components or parts such as the case with smartphones. Examples of discrete manufacturing industries include automotive manufacturing, electronics assembly, aerospace manufacturing, and consumer goods production.

Key characteristics of discrete manufacturing include:

1. Distinct Products: The end products are individual, separate items with clear boundaries.
2. ‍Bill of Materials (BOM): Products are often created using a bill of materials, which specifies the components and their quantities required for assembly.
3. ‍Customization: Products can be customized based on customer requirements, leading to variations in the manufacturing process.
4. ‍Production Batch: Production is typically organized into batches, with each batch consisting of a specific quantity of items.
5. ‍Job Shop Production: Manufacturing processes are often organized in job shops, where each job is in a unique order with specific requirements.

What is process manufacturing?

Process manufacturing is a type of manufacturing where finished goods are produced by combining ingredients or raw materials through a series of chemical or mechanical steps, often involving a continuous or batch production method and in high volume. Unlike discrete manufacturing, where products are easily distinguishable as individual units, process manufacturing involves the production of homogeneous goods, such as liquids, powders, or gases. The result of process manufacturing is typically bulk quantities of a product that cannot be separated into individual units.

Key characteristics of process manufacturing include:

1. Continuous or Batch Production: Process manufacturing often involves continuous production for items with a constant, unbroken flow (e.g., chemicals) or batch production for items produced in specified quantities (e.g., pharmaceuticals).
2. Formula or Recipe-Based Production: Products are created based on specific formulas or recipes that dictate the exact quantities and proportions of ingredients to be used.
3. Chemical or Physical Transformation: The production process usually involves chemical or physical transformations of raw materials to create the final product. This can include reactions, mixing, heating, cooling, and other processes.
4. Homogeneous Output: The final products are generally uniform and homogeneous, making it difficult to differentiate between individual units within a batch.
5. Strict Quality Control: Given the nature of the production processes, quality control is crucial to ensuring the consistency and quality of the final products.

Examples of industries and products that often use process manufacturing include chemical manufacturing, food and beverage processing, pharmaceutical manufacturing, oil and gas refining, cosmetics manufacturing, paper and pulp, plastics, and textile dyeing and finishing.

Process manufacturing relies on precision, automation, and control systems to streamline operations, maintain consistent product quality, and meet regulatory standards. It is common for process manufacturing companies to use specialized process control software and systems to manage and monitor production processes.

Challenges faced by discrete manufacturers

Discrete manufacturing industries face various challenges that can impact efficiency, competitiveness, and overall operational success. Some unique challenges include:

1. Customization Complexity: As customers demand more customized products, managing the complexity of diverse product configurations can be challenging. This complexity extends to production planning, inventory management, and maintaining efficient manufacturing processes. It requires customized production planning to accommodate variations in product designs. Unlike continuous manufacturing, where processes are more standardized, discrete manufacturing requires flexibility in planning and scheduling.
2. Short Product Lifecycles: Discrete manufacturing often involves industries with rapidly changing technologies and consumer preferences. Short product lifecycles require manufacturers to adapt quickly, introducing new products and retiring old ones, which can strain development and production processes.
3. Complex Supply Chains: Discrete manufacturing involves complex supply chains with multiple suppliers and components. The sheer quantity of components increases the complexity of assembly processes and necessitates efficient logistics and inventory management.

Managing product customization and variability in discrete manufacturing

Discrete manufacturing is well-suited to handle product customization and variability, as it involves the production of distinct, individual items. Here are several ways in which discrete manufacturing addresses product customization and variability:

1. Bill of Materials (BOM): Discrete manufacturing often utilizes a Bill of Materials, which is a detailed list of components, parts, and materials required to assemble a product. This allows manufacturers to specify and track the unique set of components needed for each customized product.
2. Work Orders and Job Orders: Manufacturing customization is often managed through work orders or job orders. Each order corresponds to a specific customer request or product configuration, allowing for the customization of products based on customer requirements.
3. Configurable Manufacturing Systems: Discrete manufacturing systems can be configured to accommodate variations in product design. Configurable assembly lines or workstations can be adjusted to handle different components or assembly steps to meet the specific requirements of each customized product.
4. Modular Assembly: Manufacturers may design products in a modular fashion, where different modules or components can be easily combined to create a variety of product configurations. This modular approach facilitates customization without the need for a complete redesign of the manufacturing process.
5. CAD (Computer-Aided Design) and CAM (Computer-Aided Manufacturing): CAD software enables the design of customized products, and CAM systems help in translating these designs into manufacturing instructions. This integration allows for seamless communication between product design and the manufacturing process, facilitating customization.
6. Automated Production Planning: Advanced planning and scheduling systems help optimize production schedules by considering different product configurations, order priorities, and resource constraints. This ensures efficient utilization of resources while accommodating variability.

By leveraging these strategies and technologies, discrete manufacturing can efficiently handle product customization and variability, allowing manufacturers to meet diverse customer needs while maintaining cost-effectiveness and production efficiency.

How Production monitoring supports discrete manufacturers

The ability to respond swiftly to changing conditions on the shop floor contributes to increased efficiency, reduced costs, and enhanced competitiveness in the dynamic landscape of discrete manufacturing. With production monitoring, discrete manufacturers benefit from:

Real-Time Visibility:

• How It Works: Production monitoring systems continuously collect data from sensors, machines, and other relevant sources on the shop floor. This data is then processed and presented in real-time dashboards, offering a comprehensive view of production activities.
• Example: A discrete manufacturer using production monitoring can instantly see the status of each machine, the progress of ongoing jobs, and the overall efficiency of the production line. This visibility helps identify bottlenecks or slowdowns, enabling quick interventions to maintain optimal production rates.

Machine Performance and Downtime Tracking:

• How It Works: Production monitoring systems track the performance of individual machines, measuring factors such as cycle times, downtime, and overall equipment effectiveness (OEE). Any deviations from expected performance trigger alerts.
• Example: If a machine in an assembly line experiences a slowdown or unplanned downtime, the production monitoring system immediately alerts operators or maintenance teams. This rapid response minimizes disruptions and helps maintain consistent production rates.

Quality Control and Defect Tracking:

• How It Works: Sensors and inspection systems integrated into the production line capture data on product quality. Production monitoring tools analyze this data in real time to detect defects or deviations from quality standards.
• Example: If a defect is identified during the manufacturing process, the production monitoring system provides immediate notifications. This allows operators to stop production, investigate the issue, and take corrective actions before defective products reach the end of the line.

Production Planning and Scheduling Optimization:

• How It Works: Production monitoring systems integrate with production planning and scheduling tools, allowing manufacturers to align production with demand. Real-time data helps in dynamically adjusting production schedules.
• Example: Suppose there's a sudden increase in customer orders for a specific product variant. The production monitoring system alerts planners, who can then adjust the production schedule to prioritize the high-demand product, ensuring timely order fulfillment.

Resource Utilization and Efficiency Enhancement:

• How It Works: By monitoring the usage of resources, such as machines and labor, production monitoring systems help optimize resource utilization. This includes identifying underutilized or overburdened resources.
• Example: The system may reveal that a particular machine is consistently underutilized during certain shifts. Based on this insight, the manufacturer can adjust shift schedules or reorganize tasks to maximize the efficiency of that machine and reduce operational costs.

Continuous Improvement Initiatives:

• How It Works: Production monitoring provides historical data and performance trends, enabling manufacturers to identify areas for improvement. This supports a culture of continuous improvement by facilitating data-driven decision-making.
