Planning 4-week plans (20 production days) Weekly tail lamp production requirement schedule by month for each model is provided in exhibit 2. AIM: To operate under just-in-time philosophy.
What do we want from you? Evaluate the performance of the existing system under JIT philosophy. –What are the problems at each stage (from purchasing to shipping)? –How can you solve the problems mentioned above?
What do we want from you? (contd) We provide some questions, which will help you to analyze the system. Find some other key questions Answer the questions Support your ideas by using the information provided in the text. –Show calculations when necessary –You can make assumptions, but state them in your report Write an engineering report.
Example The problem: The capacity is not enough to satisfy the demand in department X. –Show that demand > capacity –How did you calculate the capacity? Solution method: Buy a new machine –Is the investment cost justified?
