PT. Sejahtera Mitra Lestari is a company engaged in manufacturing industrial chemicals specifically for the rubber industry. The irregular placement of finished products in the storage can cause errors in the delivery of goods due to good management for delivering goods with a relatively fast time. The effort to overcome this problem is through designing of warehouse layout with the Class-Based Storage method. Grouping based on popularity. Stages of research carried out by calculating the warehouse, the frequency of displacement, the number of storage places, the displacement distance. Improvements begin by sorting material based on frequency and variations of three classes, namely A, B, C. To design the layout, information is needed when making a new storage layout. The results showed that the layout of the optimal results could reduce the displacement distance by 17.19% in 6 months and allow space to be 73.91%.

The stationary characteristics of an n-component periodic review system which is subject to stochastic deterioration (but not to failure) are investigated. When the n-component vector which expresses the state of deterioration of the system pierces a certain surface the entire multicomponent system is replaced by items of identical cost structure at the time of the next review. In the absence of this situation nothing is replaced. It is assumed that there is a fixed cost associated with each replacement and that the operating cost of each item is a strictly increasing function of its state of deterioration. The conditions for minimizing the long-term cost of maintaining a system which operates under the stated policy were found through solution of a problem in variational calculus. Two examples are worked. A useful graph which aids in the solution of such problems is provided.
