Visit Series Production is a manufacturing organization where the same product (or a set of similar products) is manufactured in large quantities over a long period of time, according to a process and specifications standardized.
In-depth definition : This system is the mainstay of high-volume industries (automotive, electronics, consumer goods). Its main advantage is the search for’economies of scale the larger the volume, the greater the Cost of Goods Sold unit costs, mainly thanks to the allocation of fixed’Industrialisation (tool design, initial settings, training) on a large number of units. To be effective, Series Production requires a high level of expertise. Standardization and a high level of process control, often measured by KPI (Key Performance Indicator) as the TRS (Taux de Rendement Synthétique).
The Foundations of Performance in Series Production
A mass production system is based on a number of operating principles.’Operational Excellence :
1. Specialization and Repeatability
- Process : Operations are broken down into simple, repetitive and sequential tasks. This specialization ensures a rapid learning curve for operators and the use of dedicated, highly automated machines.
- Impact: Reduces variability (a Six Sigma) and maximizes speed.
2. Standardization of workflows and controls
- Manufacturing range : Each step must be perfectly defined in the Manufacturing range and Work Instructions to ensure that each unit leaving the chain is identical to the previous one (conformity to Technical specifications).
- Quality : Visit Quality is integrated into the process (not added at the end) by systems Poka-Yoke and automatic controls (Machine Vision), often analyzed by tools such as the’FMECA to prevent defects before they occur.
3. Flow and inventory management
- Logistics : The challenge is to minimize waste (Muda) linked to inventory and transport. Modern plants are often organized into Flux Poussé (central planning based on forecasts) or integrate the principles of the Lean Management (Pulled Flow and Kanban) to regulate work in progress (WIP).
Series Production vs. Unit/Discontinuous Production
The choice of organization depends on volume and variety:
| Features | Series Production | Unitary/Discontinuous Production |
|---|---|---|
| Volume | High and constant | Low or customized |
| Variety | Low (uniform products) | High (customized products) |
| Cost Dominant | High fixed investment costs | Variable labor and material costs |
| Example | Car assembly, bottle making | Shipbuilding, highly specialized equipment |
The Challenges of Continuous Improvement
In Series Production, the initiatives of’Continuous Improvement, as the’8D analysis or the The 5 Whys, are crucial. Even a minor defect can affect thousands of units, resulting in massive non-quality costs. The objective of Industrial Engineering is therefore to make the chain as resilient as possible to the vagaries of the Supply Chain or the Maintenance.
In conclusion, the Series Production is the driving force behind modern mass production. Its success is based on a combination of automation, statistical rigor and constant discipline to maintain the highest quality standards. Standardization scale manufacturing methods.
