Contoh 1 Suatu lot sebanyak 1000 bungkus akan dibeli bila yang rusak tidak lebih dari 1%. Rata-rata kerusakan produk adalah 0.5%. Bagaimana single dan double sampling plan dengan menggunakan tabel DodgeRomig ? Single Sampling Plan  

Tabel yg digunakan : Table 1. Dodge-Romig Single Sampling Lot Inspection Table. Based on Stated Value of Lot Tolerance Per Cent Defective (LTPD) = 1.0 % and Consumer’s Risk = 0.10. Ukuran lot = 1000 maka dipakai kisaran Lot Size = 801  1000 Rata-rata kerusakan = Process Average = 0.5 % = 0.41 – 0.50% Diperoleh : Ukuran sampel (n) = 335 Angka penerimaan (c) = 1 Average Outgoing Quality Limit (AOQL) = 0.17 % Jadi jika ditemukan bungkus yang rusak  1 maka lot diterima sedangkan jika  1 maka lot harus diperiksa 100% dan yang rusak dibuang. AOQL menunjukkan bahwa prosedur ini menghasilkan lot yang kerusakannya tidak melebihi 0.17 %

Tabel yg digunakan : Table 6. Dodge-Romig Double Sampling Lot Inspection Table. Based on Stated Value of Lot Tolerance Per Cent Defective (LTPD) = 1.0 % and Consumer’s Risk = 0.10. Ukuran lot = 1000 maka dipakai kisaran Lot Size = 801  1000 Rata-rata kerusakan = Process Average = 0.5 % = 0.41 – 0.50 % Diperoleh : Ukuran sampel : n1 = 245 dan n2 = 250 Angka penerimaan: c1 = 0 dan c2 = 2 Average Outgoing Quality Limit (AOQL) = 0.19 % Jika pada sampel pertama tidak ada bungkus yg rusak maka lot diterima; sedangkan jika ada yang rusak maka dilakukan pengambilan sampel kedua. Jika jumlah rusak (I + II)  2 maka lot diterima. AOQL menunjukkan bahwa prosedur ini menghasilkan lot yang kerusakannya tidak melebihi 0.19 %



Contoh 2 Produk sebanyak 1500 dengan cacat rata-rata sebesar 1.6% dibeli oleh sebuah perusahaan. AOQL ditentukan sebesar 3.0%. Bagaimana single dan double sampling plan dengan menggunakan tabel Dodge-Romig ? Single Sampling Plan  



Tabel yg digunakan : Table 9. Dodge-Romig Single Sampling Lot Inspection Table. Based on Average Outgoing Quality Limit (AOQL) = 3.0 %. Ukuran lot = 1500 maka dipakai kisaran Lot Size = 1001  2000 Rata-rata cacat = Process Average = 1.6 % = 1.21 – 1.80 %



Diperoleh :



 



Ukuran sampel (n) = 65 Angka penerimaan (c) = 3 Limiting Quality Level (LQL) = 10.2 % Jika ditemukan produk yang cacat  3 maka lot diterima sedangkan jika  3 maka lot harus diperiksa 100% dan yang cacat dibuang. LQL menunjukkan bahwa prosedur ini menghasilkan lot produk dengan batas cacat yang dapat diterima 10.2 %

Tabel yg digunakan : Table 13. Dodge-Romig Double Sampling Lot Inspection Table. Based on Average Outgoing Quality Limit (AOQL) = 3.0 %. Ukuran lot = 1500 maka dipakai kisaran Lot Size = 1001  2000 Rata-rata cacat = Process Average = 1.6 % = 1.21 – 1.80 % Diperoleh : Ukuran sampel n1 = 49 dan n2 = 76 Angka penerimaan c1 = 1 dan c2 = 6 Limiting Quality Level (LQL) = 9.1 % Jika pada sampel pertama ditemukan produk yang cacat  1 maka lot diterima sedangkan jika  1 maka dilakukan pengambilan sampel kedua. Jika jumlah rusak (I + II)  6 maka lot diterima. LQL menunjukkan bahwa prosedur ini menghasilkan lot produk dengan batas cacat yang dapat diterima 9.1 %
