Identify and discuss some of the main elements of lean thinking and just-in-time.
How can these concepts be used for effective planning and control of an operation?
How are these two concepts (lean thinking and just-in-time) different from the materials requirements planning (MRP) system?
How can these differences be overcome to achieve the benefits of both lean thinking/ JIT and an MRP system?
The main elements of lean manufacturing or lean production are systematic elimination of waste in a manufacturing process. Typically the lean operations remove waste from excessive transport, inventories, unnecessary motion, waiting, over processing, overproduction, and defects. The main elements of just in time are improving business return on investment by reducing in-process inventory, and related carrying costs. Apart from eliminating waste lean production means identifying value stream, striving for perfection, specifying value, creating a product flow, an letting the customer pull. Just in time uses a systems approach to develop and operate a manufacturing system, organizes production so that parts are available, and ...
This solution explains lean thinking, just in time, and materials requirements planning . The sources used are also included in the solution.
Operations Management Questions: Technology, layout, capacity, MRP, productivity
1- Technology has greatly impacted the world of Operations Management. Discuss some of the potential risks and benefits associated with implementing new technology into an organization.
2- We are living in a rapidly changing global economy. As a result, organizations are being forced to make changes in order to stay competitive. Some businesses have chosen to convert from traditional manufacturing processes to a lean manufacturing environment. What does this mean? How do the two systems differ? What are some of the advantages of using lean manufacturing?
3- Layout decisions can greatly impact productivity, costs, safety, and quality. What are the 3 main types of layouts? Briefly describe each type and explain some of the advantages and disadvantages associated with each type. How can the layout help or hinder productivity?
4- Suppose you are the operations manager for a company. The company has just received a large order for a non-perishable product during its already busy season. As the company now stands, it does not have the capacity to fulfill this order. What options does the company have to try to complete the order? Which is the best alternative? What are the costs involved? Should the company accept the order or tell the customer it cannot meet its needs?
5- Material Requirements Planning (MRP) helps to ease the process of calculating inventory and scheduling needs. What is MRP? What are the three major inputs to MRP? What does MRP calculate? Suppose the Bill of Materials for a finished good is inaccurate. What problems does this pose? Provide an example.
6- A firm that manufactures tables has recently noticed a decline in productivity and is therefore, becoming less efficient. The product remains unchanged, yet the completed items per shift has declined. What are some potential causes to the decline in productivity? What can the firm do to bring productivity and efficiency back to its original rate?
