Study Notes
Introduction to Supply Chain Management
- Supply Chain Management combined various approaches in the 1990s, including:
- Quick Response (QR), focusing on speed and flexibility
- Efficient Consumer Response (ECR), emphasizes speed and flexibility
- Just-in-Time (JIT), prioritizing continuous waste reduction
- Keiretsu Relationships, fostering partnership arrangements between companies
- These approaches evolved into philosophies and practices known as Lean Production (or Lean Manufacturing) or simply Lean Thinking.
Lean Production and the Toyota Production System
- Lean Production is an operating philosophy focused on waste reduction and value enhancement.
- Originally created as the Toyota Production System (TPS) by key Toyota executives.
- Early versions of TPS were influenced by Ford assembly plants and the U.S. supermarket distribution systems.
Elements of Lean: Lean Layouts
- Lean layouts prioritize moving people and materials as quickly and efficiently as possible.
- Visually open layouts with unobstructed lines of visibility are crucial for effective lean layouts.
- Operators at one processing center should be able to monitor work at other centers.
- Manufacturing cells are utilized to consolidate and process similar parts and components, minimizing duplication of equipment and labor.
- Manufacturing cells are often U-shaped, facilitating easier operator and material movement.
Elements of Lean: U-shaped Work Cell
- U-shaped work cells are a common configuration in Lean Production, allowing for efficient workflow.
Elements of Lean: Small Batch Production Scheduling
- Small batch scheduling is employed to reduce costs by:
- Lowering purchased, work-in-progress, and finished goods inventories.
- Enhancing the firm's flexibility to meet customer demand.
- Kanbans are essential tools for small batch production, generating demand for parts at all stages of production, creating a "pull" system.
Elements of Lean: Small Lot Sizes & Flexibility
- Small lot sizes increase flexibility, as companies can adjust production according to changing customer demands.
Elements of Lean: A Kanban Pull System
- A Kanban pull system employs visual signals to manage inventory and production flows.
The Origins of Six Sigma Quality
- Six Sigma Quality focuses on achieving near-perfect quality levels, aiming for a defect rate of just 3.4 defects per million opportunities (DPMO).
- Six Sigma uses statistical tools to identify and eliminate variations in processes, leading to improved quality and consistency.
The Statistical Tools of Six Sigma: Statistical Process Control
- Statistical Process Control (SPC) is a key tool in Six Sigma, aiming to monitor and manage variations in processes.
- Natural variations are expected and random, uncontrollable influences.
- Assignable variations are caused by identifiable factors and can be controlled.
- Data in SPC can be classified as:
- Variable data is continuous (e.g., weight, length, time).
- Attribute data reflects attributes like color, satisfaction, or yes/no decisions.
Statistical Tools of Six Sigma: Variable Control Charts
- Variable control charts are used to analyze variable data, tracking the central tendency and range of sample data. Two primary types are:
- x-bar chart: tracks the central tendency (mean) of sample means.
- R-chart: tracks the range of sample data.
- Steps for constructing x-bar and R control charts are:
- Gather data when the process is considered in control.
- Calculate the mean and range for each sample.
- Calculate the overall mean and average range of all samples.
- Use the sample means to calculate the upper and lower control limits.
- Use the means and control limits to construct the x-bar and R control charts.
- Collect samples over time and plot the data on the charts.
