Abstract

Established since the 80s, PT. XYZ is an air compressor manufacturing industry located in Tangerang, Indonesia. In the production process, the Air compressor type L Unloading 1/4 HP has a very complex supply chain network which makes the supply chain network activities experience obstacles in the form of risks or potential risks that can occur so that it can disrupt the smooth running of the supply chain activities of the air compressor type L. Unloading 1/4 HP. However, PT. XYZ has not maximally implemented risk mitigation actions in its supply chain. The purpose of this study is to propose a mitigation action against risk events that occur along the supply chain of water compressor type L Unloading 1/4 HP using the FFMEA (Fuzzy Failure Mode and Effect Analysis) and FAHP (Fuzzy Analytical Hierarchy Process) methods. Based on the research, there were 29 identified risk events with 5 priority risk events. And of the 5 priority risk events, each has 2 proposed mitigation actions per priority risk event

Abstract

PT XYZ is one of the most company which produce welded steel pipe in Indonesia such as longitudinal and spiral pipes. In order to meet consumer’s demand, this company faced with an obstacle namely the distortion of information in supply chain. Distortion of information from downstream to upstream channel causes the difference between the product demand from consumer to PT XYZ and order of raw materials from PT XYZ to the supplier which is called the bullwhip effect. The objective of this research is to calculate the value of bullwhip effect as well as designing improvements to minimize the bullwhip effect. Based on the research results, obtained the index value of bullwhip effect on longitudinal pipe products is 1.06 and the index value of bullwhip effect on spiral pipe products is 0.80. The improvement design to minimize the phenomenon of bullwhip effect is to build an integrated information system for the customer, manufacturer, and supplier. The method that is used to improve the index value of bullwhip effect is Monte Carlo simulation. Monte Carlo simulation is used to obtain the order number of raw materials in order to approach the number of consumer’s demand. After applying the Monte Carlo simulation, obtained the index value of bullwhip effect on longitudinal pipe product is 1.01 and the index value of bullwhip effect on spiral pipe products is 1.00. It can be concluded that the use of Monte Carlo simulation had been optimizing the index value of bullwhip effect amounted to 4.71% for longitudinal pipe products and 25% for spiral pipe products.
