Q. 1. What is the system view of operations Management? Identify the input, process and output for the following production systems.

Answer:A System is a group of interrelated items in which no item studied in isolation will act in the same way as it would in the system. A system is divided into a series of parts or subsystems, and any system is a part of a larger system. The system’s boundary defines what is inside the system and what is outside. A system’s environment is everything outside the system boundary that may have an impact on the behaviour of the system. A system’s inputs are the physical objects of information that enter it from the environment and its outputs are the same which leave it for the environment.

Q. 3. When to use product and process layouts? Give example of organizations that have predominantly product, process and fixed position layout.

Answer:In manufacturing engineering, process layout is a design for the floor plan of a plant which aims to improve efficiency by arranging equipment according to its function. The production line should ideally be designed to eliminate waste in material flows, inventory handling and management. In process layout, the work stations and machinery are not arranged according to a particular production sequence. Instead, there is an assembly of similar operations or similar machinery in each department (for example, a drill department, a paint department, etc.)

Q. 4. Review Shigeo’s seven wastes. Which of these wastes are addressed by the following JIT techniques?

a. Pull production

b. Kanban

Answer:The seven ways that wastage can occur in industrial processes, as enumerated by Shigeo Shingo, an engineer at Toyota and a noted authority on just-in-time techniques. They are:

Q. 5. Discuss various vendor-rating techniques? Why an organisation should try to rate its vendors?

Answer:A vendor rating, also known as a supplier rating, is based on a formal system of evaluating the companies that supply materials or services to an organization. The process is meant to encourage a high-quality, efficient vendor-to-customer relationship. Overall, vendors are typically judged by both the services they offer and what capabilities they possess. A variety of factors, which depend on the particular vendor, are reviewed and the results are usually quantified with either a numerical score — possibly expressed as a percentage — or
