Penentuan Kuantitas Optimal Dan Reorder Point Pada Persediaan Suku Cadang Dengan Distribusi Gamma

Abstract: AbstrakAdanya pola demand dan lead time yang bervariasi mengakibatkan pentingnya pengelolaan suku cadang secara tepat. Penentuan kuantitas dan reorder point yang tepat sangat berpengaruh terhadap besarnya biaya persediaan suku cadang.Model biaya persediaan dikembangkan dengan mempertimbangkan ketidakpastian demand. Pada penelitian ini, demand dipengaruhi adanya kerusakan pada peralatan. Model awal biaya persediaan didekati dengan distribusi gamma. Hasil pengembangan model dengan distribusi gamma menunjukkan ba… Show more

“…Probabilistic inventory control is an inventory control model where the demand and arrival of previous orders is uncertain, but the expected values, variances, and distribution patterns can be predicted and approached based on probability distributions (Lukitosari, 2012). The probabilistic inventory control model emphasizes the importance of safety stock since the demand and lead time that cannot be easily to be determined in advance.…”

“…The probabilistic inventory control model emphasizes the importance of safety stock since the demand and lead time that cannot be easily to be determined in advance. This has had several negative effects on the achievement of company's service level where there is a possibility that the inventory will run out when the company has not placed an order, the inventory will run out when the order arrives, or the inventory will not run out when the order arrives (Lukitosari, 2012).…”

“…Metode pengendalian persediaan probabilistik adalah model persediaan dengan karakteristik permintaan dan kedatangan pesanan yang tidak diketahui secara pasti sebelumnya, tetapi nilai ekspektasi, variansi dan pola distribusi kemungkinannya dapat diprediksi dan didekati berdasarkan distribusi probabilitas [15]. Terdapat tiga metode pengendalian persediaan probabilistik, yaitu Probabilistik sederhana; Metode P, yang memiliki aturan bahwa tiap pemesanan bersifat regular pada rentang periode yang tetap dan kuantitas pemesanan berbeda-beda; Metode Q, memiliki ukuran (kuantitas) pemesanan tetap untuk tiap pesanan, dan waktu pemesanannya bervariasi [16].…”
