Spare parts are one of the important pillars in the after-sales service of automotive business. Customers will satisfied and comfortable if the availability of spare parts is guaranteed. Spare Part Center is one of function to support unit sales and as well as profit-oriented, so the accuracy and speed of spare part acceptance by the customer is an important key to winning the competition. Order Picking is one of the supply chain processes that play a role in warehouse operations to meet customer needs. Order Picking is the most expensive activity in warehousing and can reach 55% of the total cost of warehousing operations, so it is considered a top priority in increasing productivity, even reaching 65% of total warehouse operating costs. The purpose of this research is to increase productivity in the process of picking order through reduction of processing time. Increased productivity is done by improving the working method of the picking process. From the result the comparing, the method by zone requires less total picking time (193.712 seconds) than by routing (249.559 seconds) decreased 55.85 second time, in other words, an increase of 22.38%. With the Visual Stream Mapping (VSM) in this research can reduce to travel time, it means that the total distance traveled is small than the current method. The impact from VSM approach will eliminate time for preparation of 1.960 seconds, and take empty trolley of 200 seconds. In this case some of traveling non-value
The implementation of milk-run in Indonesia has been started since 2005. As a developing country, there is a challenge to operate milk-run smoothly especially in urban area due to severe traffic congestion and unfavourable road condition in some areas. This research aimed to analyze the practice of milk-run operation in one of the biggest Japanese automotive companies in Indonesia. Transportation Value Stream Mapping (TVSM) is applied in order to perform just-in-time delivery in the supply chain before operating milk-run. It is discussed that this company still need to continue in improving milk-run operation. The operation system needs control and integration from manufacturer, supplier and logistics partner. The advantage of milk-run operation is cost reduction and also support green logistics in decreasing emission of carbondioxide (CO2) by reducing the number of trucks used.
