Dalam distribution resource planning worksheet terdapat beberapa istilah
yang perlu diketahui, yaitu:
1. On Hand Balance adalah jumlah persediaan awal produk yang ada pada
distribution center.
2. Safety Stock adalah persediaan untuk melindungi atau menjaga kemungkinan
terjadinya kekurangan produk.
3. Lead Time adalah waktu yang diperlukan dalam pelepasan order sampai
order diterima di stock room pada distribution center.
4. Order Quantity adalah jumlah produk yang dikirimkan ke untuk setiap kali
pemesanan.
5. Demands Forecast adalah peramalan jumlah permintaan dari masing-masing
distribution center.
6. In Transit adalah jumlah produk yang sedang dalam proses pendistribusian.
7. Projected On Hand adalah persediaan yang ada dan siap digunakan.
8. Planned Shipments – Receipt Date adalah jadwal perencanaan penerimaan
produk yang dikirim.
9. Planned Shipments – Ship Date adalah jadwal perencanaan pengiriman
produk.
Distribution Resource Planning Worksheet untuk setiap masing-masing
distribution center dapat dilihat pada Tabel 5.16 hingga tabel 5.24.

3. OrderQuantity = 800sak (diperoleh dari Tabel 5.13.)
4. Safety Stock = 349 sak (diperoleh dari Tabel 5.12.)
5. Projected on Hand (Past Due) = 297 sak (diperoleh dari On Hand Balance)
6. Net Requirement = 1.911 – 297 = 1.614 sak
7. Demands Forecast(1stWeek) = 1.911sak (diperoleh dari Tabel 5.12.)
8. In Transit (1stWeek) = 0, (tidak adanya produk yang sedang dalam proses
pengiriman)
9. Planned Shipments - Ship Date = 2.400 sak (diperoleh dari Order Quantity)
10. Planned Shipments - Receipt Date = 2.400 sak (diperoleh dari Order
Quantity)
11. Projected on Hand (1st Week) = Projected on Hand (Past Due) + Order
Quantity – Demands Forecast (1st Week) = 297 + 2.400 – 1.911 = 786sak
12. Demands Forecast(2nd Week) = 1.911sak (diperoleh dari Tabel 5.12.)
13. Projected on Hand (2nd Week) = Projected on Hand (1st Week) + Order

Pada Tabel 5.18 sampai dengan Tabel 5.26. dapat dilihat DRP worksheet
yang pada enam distribution center, yaitu Jambi, Lubuk Linggau, Tembilahan,
Pekanbaru, Rengat, Siak, Ujung Tanjung, Bengkulu dan Sibolga. Pada DRP
worksheet terlihat perencanaan pengiriman produk, penerimaan produk, jumlah
produk yang tersedia di distribution center, dan jumlah permintaan produk pada
masing-masing distribution center berdasarkan peramalan. Perencanaan pada
DRP worksheet dilakukan untuk 12 bulan kedepan yang dibagi kedalam 52
minggu.
DRP worksheet mengacu pada jumlah permintaan di awal periode, safety
stock, lead time, serta order quantity. Order quantity merupakan jumlah
pengiriman produk yang optimal padsa setiap pemesanan dan safety stock
merupakan titik acuan pemesanan kembali produk.
