THE DETERMINATION OF OPTIMAL INVENTORY USING MARKOV CHAIN
ABSTRACT: The complication of
inventory is a crucial problem for the company because inventory is one of the
valuable assets for the company. The existence of inventory control is needed
so the inventory levels that exist within the company is not in very large
(optimal) therefore the costs incurred by the company can be suppressed as
minimum as possible. PT NM is a company engaged in spare parts, especially branded
cars in West Jakarta. The level of inventories of goods owned by these
companies is high because The company did not want to experience stock
out of stock but on one side the stock is large enough so the costs
incurred by companies
such as storage costs of goods becomes even greater. In order to control
inventory levels, this study uses a Markov Chain method that can identify
optimal inventory level and the expectation of profits earned per month by
making estimates of the future demand a previous demand. From the research
results shows expectation of profit of each state starting from state 2 to
state 10 is Rp 13.146,98921; Rp 12.246,94064; Rp 11.346,61466; Rp 10.444,64569;
Rp 9.534,074035; Rp 8.584,408534; Rp 7.484,413248; Rp 5.913,288143; Rp 3.211,609986,-.
While the profit expectations that earned by the company per month is Rp
694.233,333, and the optimal inventory level is 50.
