Zusammenfassung: | In this paper, an attempt has been made to develop a simple leakage inventory
model without shortages with instantaneous or finite production rate under
fuzzy environment. In the present day scenario, it is difficult to decide the
exact annual demand rate and hence a major difficulty is faced by a decision
maker to forecast the demand. Also, in any inventory system, goods in stock may
subject to deterioration or leakage. Deterioration of goods refers to decrease
in quality whereas quantity remains more or less the same. On the other hand,
leakage refers to loss in quantity whereas the quality remains unchanged for a
certain period of time. Leakages in the inventory system may be considered to
be very small, not detectable by the management immediately and hence it is
difficult to decide the exact leakage rate. The objective of this paper is to
consider these variable parameters and determine the optimal economic order
quantity (EOQ) to maximise the annual total profit. So, fuzzy inventory models
have been proposed considering fuzzy leakage rate and fuzzy annual demand rate
to estimate the total profit per unit time. Signed distance method is used for
defuzzification. Numerical examples are provided to support the results of the
proposed models. |
