Q.3 What is reserve analysis?
Well, reserve analysis is among the most common techniques used to determine the budget of a project. During reserve analysis, a project is analyzed from a cost overrun point of view, and buffers are placed in the relevant place. Hence, these buffers are known as contingency and management reserves.

Report This Question
Q.57 What are the factors affecting PPC?

The factors that affect the application of production planning and control to manufacturing are - 


  • Type of Product –The complexity of the product that is important, not what the product is, except as this may, in turn, relate to the market being served. Production control procedures are much more complex and involve many more records in the manufacture of large steam turbine generator sets or locomotives to customer orders than in the production of large quantities of a standard product involving only a few component parts, such as electric blankets, steam irons, or similar small appliances.
  • Type of Manufacturing – This is probably the most influential factor in the control situation. For a large continuous manufacturing plant producing a standard product, we have already indicated that the routing was included in the planning of the plant layout.
