Answer : Concepts in analyzing the investment :

1. ROI :
Return on investment (ROI) is the concept of an investment of some resource yielding a benefit to the investor. A high ROI means the investment gains compare favorably to investment cost. As a performance measure, it is used to evaluate the efficiency of an investment or to compare the efficiency of a number of different investments. In purely economic terms, it is one way of considering profits in relation to capital invested. In business, the purpose of the "return on investment" metric is to measure, per period, rates of return on money invested in an economic entity in order to decide whether or not to undertake an investment.

Moving materials around does not add value for the customer and it increases the risk of damage, incorrectly routed items, lost items, and delays affecting other parts of the production process.


Q.5  Discuss the Independent demand item techniques.
(Reorder point (or Perpetual) Model – 5 marks; Periodic review models – 5 marks) 10 marks

Answer :  Independent demand item techniques :

The two classic systems for managing independent demand inventory are periodic review and perpetual review systems.

1. Reorder point model :

A perpetual inventory tracking system is a method of immediately accounting for inventory sales in the inventory account, if there is no theft or spoilage. It is an inventory management system where store balances of inventory are recorded after every transaction. It eliminates the need for the store to close down constantly for inventory stock-taking as perpetual inventory systems allow for continuous stock-taking. Perpetual inventory systems keep a running account of the company's inventory.

Some design failure occur because a characteristics of demand was overlooked or miscalculated .A production line might have been installed in a factory which in practice cannot cope with the demands placed on it. Other design related failure occur because the circumstances under which operation has to work  are not as expected.
