Demand Forecasting and Inventory Management:
A short course
Demand Forecasting: Importance of forecasting; qualitative techniques of
Forecasting models: Moving average, Weighted moving average, exponential
Advanced forecasting models: Exponentially weighted moving average; isolating
trend and seasonal components.
Measures of forecasting accuracy and error. Case study on forecasting.
Inventory Management: Types of inventory, inventory costs, performance
Economic Order Quantity (or Interval) model: Basic model, all-units quantity
discount model, etc.
Just-in-time procurement: Definition and comparison with the EOQ model.
Material Requirement Planning: Using MRP to determine order schedules for
Vendor-managed inventory: Realities and myths surrounding VMI practice.
This objective of this course is to familiarize the participants with the demand
forecasting and inventory management techniques and strategies. They would also
come to appreciate the pros and cons of the newly emerging approaches, and what it
takes to implement them.
The course would also enable the participants to appreciate the important role the
demand forecasting and inventory management functions play in effective supply-
chain management of their companies.
During the course, the participants would be given a chance to apply their newly
acquired knowledge to test by working on simple yet powerful quantitative examples.
They would also be exposed to some real-life case studies to help illustrate the
techniques and technologies learned.
Who Should Attend
This course is especially designed for Inventory, Materials Management and
Purchasing executives in the electronics, semiconductor, or any discrete-part
manufacturing company. The participants would find the contents state-of-the-art,
and the course helpful in streamlining their demand forecasting and inventory
management operations. This in turn would help them to optimize the entire supply-
chain their company is part of.
