The problem of distribution is a problem that cannot be separated from the industrial world. These problems are because these problems have a considerable influence on the cost and level of service to consumers. Therefore we need a way so that the distribution process can run smoothly and on time. One way that can be done in the distribution process is to optimize vehicle routes so that the time spent serving two consumers is more efficient and the goods can get to consumers on time. The problem of optimizing vehicle routes is known as vehicle routing problem (VRP). VRP which aims to form an optimal route to serve consumers with capacity constraints and Type of Vehicle is called Multi-type vehicle routing problem (MTVRP). In solving the MTVRP problem, two methods will be combined namely the exact method and the heuristic method. The firefly algorithm has been widely used in solving VRP problems. The results are obtained total distance of 2488 km.
Quality control is a system and activities to ensure quality standards in accordance with planned specifications. Quality control is also one of the important things that can affect the company’s image for consumers. Balikpapan center is one of the biggest shopping centers in Balikpapan, East Kalimantan, at present there are 37 hijab traders on the same floor, resulting in trade competition. A good strategy is needed to be able to sell comfortably, where this strategy will minimize the risks that can arise. One method used is failure modes and effects analysis (FMEA). The use of FMEA can be used to identify risks and risk factors and obtain the value of potential failure, so that the greatest failure risk experienced by traders can be identified. The purpose of this research is to analyze the failure factors in the hijab industry, use the FMEA method, determine the risk of failure value in the risk priority number (RPN), and provide improvement plans for traders.. The results showed that there were 3 risk classifications, 12 risk factors, and 15 risk mitigation strategies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
