Study Notes
Demand Forecasting
- Demand forecasting predicts future sales, with methods including time-series analysis, market research, expert opinion, regression analysis, and leading indicators.
- Time-series analysis is useful when demand increases during the holiday season.
- Customer surveys relate to market research as a forecasting method.
- Historical data and sales trends inform exponential smoothing techniques.
- Expert opinion is useful for startups or new products with limited or no past data.
- Regression analysis captures the relationship between variables to forecast demand.
- Historical sales data is used in time-series analysis to estimate future demand for seasonal products.
- Using GDP growth rate to predict future demand for consumer goods is an example of leading indicators.
- Sales teams that forecast demand based on their experience and intuition are using expert opinion.
- Smoothing out fluctuations in sales data for forecasting future demand is exponential smoothing.
Inventory Control Techniques
- Safety stock maintains excess inventory for demand spikes or supply delays.
- A reorder point system orders a fixed quantity of inventory when stock falls below a certain level.
- The Economic Order Quantity (EOQ) model calculates the optimal order quantity to minimize costs.
- ABC analysis classifies inventory items into high-value, medium-value, and low-value categories.
- Just-in-Time (JIT) aims to maintain a consistent flow of inventory with minimal holding costs.
- EOQ is best suited for calculating the most economical quantity to order by considering both ordering and holding costs.
- A point-of-sale system will reorder ingredients when the stock runs low within a JIT system.
- Using historical sales data to determine when to reorder stock and how much to order is EOQ.
- Aligning inventory with production schedules using forecasts minimizes storage costs in JIT.
- Vendor Managed Inventory (VMI) involves a supplier tracking a customer’s inventory and restocking automatically.
Lean Operations and Continuous Improvement
- Reduction of waste improves efficiency by eliminating unnecessary production steps.
- Cellular manufacturing organizes machines in a sequence matching the production flow to reduce downtime.
- Kanban is a "pull" system where products are made to order based on customer demand.
- Continuous improvement involves regular employee workshops to identify production inefficiencies.
- 5S organizes workstations and tools systematically to reduce unnecessary movement.
- Continuous flow ensures processes run without interruption or delays.
- Value stream mapping maps the entire production process and eliminates non-value-added activities.
- Six Sigma identifies root causes of inefficiencies using data analysis and process improvements.
- Reorganizing a warehouse to minimize steps in handling products reduces motion waste.
- Using real-time data to monitor production processes and identify improvements is visual management.
Supply Chain Management
- Supply chain optimization minimizes transportation costs and inventory levels.
- Collaborative Planning, Forecasting, and Replenishment (CPFR) improves the flow of goods and information.
- Network optimization determines the most cost-effective way to move goods.
- Risk management uses multiple suppliers for critical components to reduce disruption risks.
- Supply chain performance management tracks customer satisfaction, inventory turnover, and order fulfillment.
- Identifying potential risks that could disrupt its supply chain is risk management.
- Total Cost of Ownership (TCO) calculates the total costs associated with a supplier's delivery performance.
- Developing contingency plans for supply chain disruptions pertains to supply chain risk management.
- Collaborating to predict demand accurately and improve production planning is CPFR.
- A Kanban system triggers production by actual customer orders.
- Just-in-Time (JIT) minimizes excess inventory and improves cash flow by ordering just in time.
- Vendor Managed Inventory (VMI) uses real-time data to manage inventory levels at a customer's location.
- Cross-docking streamlines product movement through the distribution center, which improves transportation efficiency.
- JIT synchronizes production with customer demand reducing lead times .
- Network optimization evaluates transportation options, lead times, and customer demand to optimize its supply chain network.
- Sharing production plans to ensure parts are delivered on time is supplier relationship management.
- Reusing materials in its supply chain is sustainability in supply chain.
- Eliminating bottlenecks in its production processes to improve the overall flow of materials aligns with lean manufacturing.
- Supplier performance management involves tracking suppliers' performance and making adjustments based on delivery accuracy.
- Coordinating the supply chain to ensure timely deliveries without excess inventory is JIT.
