Abstract— CV.Cipendawa is a shoe company, which was established in 2005. The brand of goods produced is Allstar shoes, which become main products. Problems that occur in the process of shoe production Allstar is a waste in the form of idle time (idle time). Waste in the form (idle time) occurs because the company does not pay attention to the existence of alternative Allstar shoe assembly making the engine scheduling less good. This research is done by using lean manufacturing and machine scheduling, in lean manufacturing concept in using the operation of process chart (OPC) and value stream mapping (VSM) to describe the value in production process which includes material and information flow. While the machine scheduling is used to reschedule the production process of Allstar shoes so it is expected to reduce waste. The purpose of this research is to minimize the time of completion of production by paying attention to the assembly alternatives on the production floor. The results of this study indicate that with the scheduling of machines that pay attention to the order of prakitan get the completion time of production of 718 seconds and the waiting time of 114 seconds.dan on making a single shoe score add value of 7102 seconds Keyword : value stream mapping and Scheduling machine.

Abstract

An integrated approach to distribution route design considers several aspects of the distribution network simultaneously such as customer distribution grouping, warehouse locations, routes and vehicle capacity. This approach aims to optimize these factors as an integrated system so that vehicle travel routes are shorter and more efficient and save overall costs. For this purpose, the use of complex mathematical models in designing distribution routes is unavoidable. Distribution route design begins with grouping retailers/agents so that transport vehicles in only one trip can complete their tasks using the Fuzzy c-Means Clustering approach. The next step is the selection of warehouse locations that consider the distribution of demand from retailers/agents in each cluster. For warehouse location selection that is centered on the distribution of retail/agent demand, geographic analysis is very important to map areas with high demand concentrations, so that placing warehouses close to the majority of customers can speed up delivery times and minimize transportation costs. This step uses the P-Median approach with the Greedy Dropping Heuristic Algorithm. This design ends by determining the optimization route using Insertion Heuristic or Vehicle Routing Problem in each cluster, starting with the vehicle departing from the warehouse providing service until all retailers/agents in the cluster are served and returning to the warehouse in just one iteration. The next approach, Tabu Search metaheuristic, is carried out to see other possible shortest distance alternatives by optimizing the shortest distance obtained in the previous stage. This design is applied to the 3 kg gas distribution route in East Bandung City which has six intermediary warehouses and 72 retailers/agents. The integrated design of the 3 kg distribution route produces a cost efficiency of 72.28%. Pendekatan terpadu terhadap perancangan rute distribusi mempertimbangkan sejumlah aspek jaringan distribusi secara bersamaan seperti pengelompokan sebaran pelanggan, lokasi Gudang, rute dan kapasitas kendaraan. Pendekatan ini bertujuan mengoptimalkan faktor-faktor tersebut sebagai satu sistem yang terintegrasi sehingga rute tempuh kendaraan lebih pendek dan efisien serta menghemat biaya keseluruhan. Untuk tujuan ini, penggunaan model matematika kompleks dalam merancang rute distribusi tidak dapat dihindari. Desain rute distribusi diawali dengan mengelompokkan ritel/agen agar kendaraan angkut dalam hanya satu ritasi dapat menyelesaikan tugasnya dengan pendekatan Fuzzy C-Means Clustering. Langkah berikutnya adalah pemilihan lokasi gudang yang mempertimbangkan sebaran permintaan daripada ritel/agen di setiap klaster. Untuk pemilihan lokasi gudang yang berpusat pada sebaran permintaan ritel/agen, analisis geografis sangat penting untuk memetakan area dengan konsentrasi permintaan tinggi, sehingga menempatkan gudang dekat dengan mayoritas pelanggan dapat mempercepat waktu pengiriman dan meminimalkan biaya transportasi. Langkah ini menggunakan pendekatan P-Median dengan Greedy Dropping Heuristic Algorithm. Perancangan ini diakhiri dengan menetapkan rute optimasi menggunakan Insertion Heuristik atau Vehicle Routing Problem pada setiap klaster dengan diawali kendaraan berangkat dari gudang memberi pelayanan hingga semua ritel/agen dalam klaster terlayani dan kembali ke gudang hanya dalam satu ritasi. Pendekatan berikutnya metaheuristik Tabu Search dilakukan untuk melihat kemungkinan alternatif jarak terpendek lainnya dengan melakukan optimisasi jarak terpendek yang telah diperoleh pada tahapan sebelumnya. Perancangan ini diterapkan pada rute distribusi gas 3 kg Kota Bandung Timur yang mempunyai enam gudang perantara dan 72 ritel/agen. Perancangan terpadu rute distribusi 3 kg menghasilkan efisiensi biaya sebesar 72,28%.
