Economic growth based on economic sharing encourages e-commerce transactions to increase. Along with this, the need for an effective distribution process is also increasing, in order to fulfill orders quickly and accurately. This study was conducted on the logistics department at one of the retail companies providing electronic equipments and accessories. Preliminary observations indicate the high level of overtime experienced by employees in the logistics department, as well as the high rate of errors in delivery of ordered products, which results in high complaints from customers. The aim of the study is to evaluate the performance of the order picking process that is currently being carried out by the company, and to formulate a suitable approach to be applied by the company. The research was conducted with a discrete simulation approach, using Flexsim v2022. Modeling begins with creating entities according to the actual warehouse specifications. After that, the model is developed by determining the process flow or simulation flow, by entering parameters such as the number of orders, time, and shelf location. The simulation results show that the current wave picking approach is not optimal. The simulation shows that the sequential zone picking strategy is estimated to result in a decrease in the time of order pickings and the distance experienced by the officers, so that it can be a strategy that can reduce the rate of overtime and errors in order pickings.

A manufacturing company in Indonesia creates sports shoes under the particular brand is still having trouble with a number of issues, including late raw material deliveries from suppliers, production that falls short of expectations, and delayed product delivery to customers. The performance of the supply chain must therefore be measured. The study assesses the importance of supply chain performance within the organization and offer recommendations for improvement to raise supply chain performance within the organization. Analytical Hierarchy Process (AHP) and Supply Chain Operation Reference (SCOR) 12.0 are used to gauge supply chain performance. The outcomes revealed that supply chain performance’s value at 77,539. Improvements are required to increase the company's supply chain performance because three KPIs have low weights, the percentage of orders for raw materials that are delivered on time, the price of purchasing raw materials, and the cost of returning item. Corrective actions carried out by the company include arranging materials neatly in the warehouse, providing sufficient lighting, maintaining air humidity, keeping hands clean when holding shoes, checking glue on the upper shoes so that open bonding does not occur, giving penalties to suppliers who are late, and giving training to reduce material damage.

Every company must have a good supply chain flow to support the company's development. A series of complex supply chain processes makes business processes unavoidable from risks that have a negative impact. Some risk events that are often found include the inability of suppliers to fulfill orders on the specified date, problems experienced by machines, and others. To overcome the risks that arise, it is necessary to manage supply chain risk management using the House of Risk (HOR) approach. The HOR method consists of 2 phases, HOR phase 1 focuses on risk events and priority handling of risk sources (risk agents) that will be subject to risk mitigation assistance measures to deal with negative pathways from these risks. While HOR phase 2 focuses on designing mitigation actions that will be applied to companies to deal with the negative impacts of risks and prevent risks from happening again. The results of the study showed that there were 47 risk events and 48 risk agents with 2 priority risk agents. Thus, 8 risk mitigation action strategies and 3 priority risk mitigation action strategies have been set to mitigate the existing risk agents.
