  1. Peta Kendali Variabel

  2. Menggambarkan variasi atau penyimpangan yg terjadi pd kecenderungan data variabel • Kondisi in-out of control tapi tdk identik dg kepuasan pelanggan

  3. Manfaat… • Perbaikan kualitas • Menentukan kemampuan proses • Membuat keputusan berkaitan dg proses produksi dan produk yg dihasilkan

  4. Tahapan… • Pemilihan karakteristik kualitas • panjang, berat, volume, waktu • Mempengaruhi kinerja produk • Pemilihan karakteristik dg Diagram Pareto

  5. 2. Pemilihan Sub Kelompok

  6. 3. Pengumpulan Data 4. Penentuan Batas Kendali untuk pet X-R dan Nilai Faktor Guna

  7. From Table Nilai Guna Range for sample i Mean for sample i # Samples X Chart

  8. Nilai Faktor Guna

  9. From Table Nilai Guna Range for Sample i # Samples R Chart

  10. Process Capability Ratio, Cp

  11. Process Capability Cpk Assumes that the process is: • under control • normally distributed

  12. Warning Conditions….. Western Electric : • 1 titik diluar batas kendali ( 3σ) • 2 dr 3 titik berurutan diluar batas kendali (2σ) • 4 dr 5 titik berurutan jauh dari GT (1σ) • 8 titik berurutan di satu sisi GT • Giliran panjang 7-8 titik • 1/beberapa titik dekat satu batas kendali • Pola data TAK RANDOM

  13. x Chart

  14. R- Chart

  15. Contoh

  16. n = A2 = D4 = D3 = • GT = • BKA = • BKB =

  17. n = 5 A2 = 0,577 D4 = 2,115 D3 = 0 • GT = • BKA = • BKB =

  18. X¯(rata-rata) = ni (Xi)/ni • R¯ = ni (Ri)/ni • BP-X¯ = X¯rata-rata ± A2.R¯ • BPA-R = R¯D4 • BPB-R = R¯D3

  19. Xֿ(rata-rata) = GT peta kendali X = 7(8,57) +6(8,17)+…+4(13,25)+7(10) 7+6+7+……+4+7 = • Rֿ = GT peta kendali R =7(11)+6(6)+7(7)…+4(7)+7(6) 7+6+7+…+4+7 = Ada 10 macam BATAS KENDALI
