Rancangan proses

Seleksi proses merupakan serangkaian keputusanmengenai tipe atau jenis produksidan peralatan yang digunakan.

Klasifikasi :1. Aliran Produk atau Proses:1. Aliran Produk atau Proses:

a. garis.b. Intermitenc. Proyek

2. Tipe Pesanan Pelanggan :

Aliran Garis :Produk terstandarisasi dan mengalir dari satuoperasi atau tempat kerja ke operasi berikutnyadengan urutan yang telah ditetapkan sebelumnya.a. Produksi Massa (mass production): memproduksi

kumpulan-kumpulan produk dalam jumlah besardengan mengikuti serangkaian operasi yang sama dengan kumpulan produk sebelumnya sama dengan kumpulan produk sebelumnya repetitive process. contohcontohcontohcontoh : operasi lini perakitan.

Operasi / tempatkerja

Aliranproduk atau

bahan

b. Produksi terus-menerus (continuous).:ditandai dengan waktu produksi yang relatiflama untuk menghindari penyetelan, persiapanlian dan kemacetan yang mahal industri-industri proses

Aliran Intermiten (Job Shop)

Kelompok barang yang sejenis pada interval-interval waktu yang terputus-putus.Peralatan dan tenaga kerja diatur dalam pusat-pusat kerja menurut tipe-tipe ketrampilan atauperalatan yang serupa.

Operasi / Tempat kerja

Operati intermiten sangat fleksibel dalam perubahanvolume atau produk, karena dalamoperasinya menggunakan peralatan serbaguna dan tenaga kerja berketrampilan tinggi

Masalah: dalam pengendalian persediaan, skeduldan kualitas.

Digunakan untuk barang-barang tidak distandarisasiatau volume produksinya rendah

Aliran ProyekDigunakan untuk memproduksi produk-produkkhusus atau unik.

Masalah signifikan : perencanaan, pengurutan, sceduling danpengawasan kegiatan-kegiata individual yang mengarahkan penyelesaian proyek secarapengawasan kegiatan-kegiata individual yang mengarahkan penyelesaian proyek secarakeseluruhan.

Bentuk operasi proyek digunakan bila adakebutuhan akan kreatifitas dan kekhususan dalampembuatan suatu produk

Dimensi kritis lain yang mempengaruhi pemilihanproses adalah apakah produk dibuat untukpersediaan (production to stock) atau untuk pesanan(production to order).

Proses produksi pesanan berdasarkan ataspermintaan atau pesanan, dimana kegiatanpermintaan atau pesanan, dimana kegiatanpemrosesan menyesuaikan dengan spesifikasipesanan (tidak standar) dengan waktu yang disepakati.

Produksi persediaan dengan garis produksi yang distandarisasi, guna memenuhi permintaan yang tidak pasti dan merencanakan kebutuhan kapasitas.

Application of Decision Trees to Product Design

Particularly useful when there are a series of decisions and outcomes which lead to other decisions and outcomes.

Considerations:Include all possible alternatives and states of nature - including doing nothing

Enter payoffs at end of branch

Approach determining expected values by pruning tree

95

Transition to Production

First issue: knowing when to move to production!

Second: must view product development as evolutionary, not responsibility of single individual/department

Third: expect to need a trial production period to Third: expect to need a trial production period to work the bugs out

Fourth: recognize that responsibility must also transition
