Penelitian ini bertujuan untuk menganalisis pengendalian persediaan obat pada Apotek XYZ sehingga pihak apotek dapat mengetahui secara efektif dan efisien. dilakukan dengan menghitung analisis metode ABC berdasarkan nilai pemakaian. Dari penelitian diketahui dari hasil pemakaian kelompok A terdiri 3 item atau 14,36% jumlah sebesar Rp. 88.090.000 58,89%. Kelompok B 4 19,39% 46.236.000 30,91%. C ...

Drugs are essential, if there is a shortage of drug at the pharmacy can cause vacancy, then what should be controlled, how much ordered, and when reordered. The purpose this study steps in control process determinants, including number sales knowing planning system inventory. method ABC classification analysis to find out which drugs priority control, Economic Order Quantity (EOQ) many must ord...

This study proposes an EOQ inventory mathematical model for deteriorating items with exponentially decreasing demand. In the model, the shortages are allowed and partially backordered. The backlogging rate is variable and dependent on the waiting time for the next replenishment. Further, we show that the minimized objective cost function is jointly convex and derive the optimal solution. A nume...

Abstract In this Paper a multi item EOQ model with stock dependent demand for deteriorating items is considered in fuzzy environment. Inventory costs such as holding cost and setup cost have been represented by exponential membership function and profit, deteriorating rate and total investment constraint are represented by linear membership functions. The model has been solved by fuzzy non-line...

Inventory control can be done by reducing the cost of inventory and number ordering frequencies economically. PT Tanjung Globalindo Utama or Toko TODA is an oil accessory retail store that provides various needs. Some problems are late delivery goods from suppliers, so for several days company cannot operate optimally. On other hand, has also experienced excess merchandise, wastes due to mercha...

Inventory of raw materials or at PT. PGP has not been planned properly so that one time the run out during production process. management applied by company paid attention to economical order quantity, and also point reordering materials. This course an impact on additional costs should be needed, in other words it is effective efficient, sees need apply EOQ method managing study aims determine...

In this paper the authors consider the continuous deterministic, infinite horizon, single item inventory system within the setting of a retailer sector in which the demand rate for an item is time dependent. The parameter of the replenishment cost is kept constant, but the carrying cost per unit is allowed to vary. The optimal policies are found, and decision rules and classical EOQ model have ...
