Inflasi menyebabkan harga per-satuan barang naik di masa depan. Untuk mengimbangi inflasi, perusahaan dapat memanfaatkan discount yang diberikan oleh supplier. Tetapi pemesanan barang harus disesuaikan dengan permintaan untuk menghindari peningkatan biaya penyimpanan. Penelitian ini menjelaskan mengenai model inventory probabilistik dengan permintaan pada waktu tunggu berdistribusi Gamma dan mempertimbangkan adanya faktor discount dan inflasi. Kondisi backorder diperbolehkan dalam pembentukan model ini. Penelitian ini menghasilkan bentuk model inventori probalilistik dan algoritma untuk mendapatkan jumlah pemesaann optimal dan waktu pemesanan optimal untuk barang-barang yang all unit discount dan mengalami inflasi dengan permintaan berdistibusi Gamma.
[Inflation causes the price per unit of goods to rise in the future. To offset inflation, companies can take advantage of discounts provided by suppliers. But ordering goods must be adjusted according to demand to avoid storage costs. This study describes a probabilistic supply model with demand at a time with a Gamma distribution and waiting for the discount and inflation factors. Backorder conditions in this model is assumed. The research produces a probabilistic inventory model and an algorithm to obtain the optimal number of orders and optimal ordering times for items that are all discounted and inflated with Gamma distribution demand.]
