Abstract

PT Toyota Motor Manufacturing Indonesia (TMMIN) have business at export service part. This business have problem at procuring time from Toyota Astra Motor (TAM) as customer to TMMIN. Lead time for TAM order to TMMIN is 13 days while the standard procuring time is 2 days. The differences make some order status is backorder or delay. The differences caused by TMMIN procuring timing only once every month. This study give advice to using weekly order change (WOC). WOC can be applied but need to consider production capacity and raw material limit. That factor will be used for limitation at simulation. Simulation will use order date at backorder shipment and emergency order data from January until March 2016. Data will be used for simulation input with limitation at production capacity and raw material. Current lead time ordering process can be reduce until 3 days with WOC.

There are various selling system or distribution system in this company and one of them is Pre Order system (PO). The vehicle types that used for delivery on this system are blind van, Colt Diesel Engkel (CDE), and Cold Diesel Double (CDD). The purpose of this research is to discovered route optimitation so it can shows how many vehicles are needed for the delivery. It also can decrease the operational cost for the delivery. This route optimitation simulation is based on the existing route but it had been optimized with arranging the delivery using the Nearest Neighbor Insertion (NNI) concept where the delivery route will be using the shortest route. This PO delivery system also using the combination of Vehicle Routing Problem with Time Windows (VRPTW), Vehicle Routing Problem with Heterogenouse Fleet of Vehicle (VRPHFV), and Vehicle Routing Problme with Multiple Trips (VRPMT).The result of this simulation is the total number of vehicles that can be decreased in one week are 34 unit. In Bogor, Ciracas and Pulo Gadung, 1 unit of vehicle can be removed for Senin until Thursday (1*4*3=12). In Sunter, there are 3 unit of vehicles that can be removed for Monday until Thursday (3*4) and lastly in Tangerang there are 2 unit of vehicles that can be removed for Monday untul Friday (2*5=10). The distances that should be taken are decreased from 9,604 km to 8,028 km with total duration 1372,01 hours when it actually should be taking 1484,3 hours. The reducing of distance and time become a great additional benefit for the company because the company can save more fuel that can also reduce the polution of CO2.

Abstract

Inventory is the thing to consider in ordering. Inventories have a variety of properties, one of which is a level of decline. Many researchers have done research on multi-item inventory but not with inventory are deteriorating and assume constant demand. The real condition that occurs today is that the company sells multi-item inventory in the presence of stochastic deterioration and demand. The situation is approached by building a model of inventory simulation using real data in Pin'kan Bakery. The simulation model is done with the help of monte carlod simulation and evolutionary algorithm. This study will compare two ordering modes, namely continuous review and periodic review. The results show that the continuous review method is an appropriate ordering method for multi-item inventory ordering with stochastic degrees and demand.

Abstract

PT Toyota Motor Manufacturing Indonesia (TMMIN) is an automotive company in Indonesia that operates as a manufacturer and exporter of Toyota products and spare parts. One of TMMIN’s export activity is Component Part Order (CPO). CPO handling is done using the help of the system, but the current system has problems, which is the occurrence of system errors. The current system is also not able to display tracking order visualization so there is often a process delay occurs in handling CPO. Analysis of the cause of process delay is done using Toyota Business Practice (TBP) and Ishikawa Diagram. Improvements made is to design a new system so that system error problems that occur in the old system can be eliminated. The system is also designed to have an order tracking function so that every process of CPO handling can be recorded in the system. Improvements to deal with CPO operational issues are also designed in the system. Goals of this improvement is to achieve a smooth and on time CPO handling. Another expected advantage of this improvement is the saving of 2244 hours / year of work time required to solve the problem.
