This article presents a study on the development of a bi-objective cost problem optimization model in planning tourist routes in the island zone. This problem is a new variant of the tour route plan problem. Bi-objective view of two cost components, namely maritime transportation costs and ground transportation costs. Two models were formulated using a mixed integer linear programming approach. The first model was designed to minimize one of the two cost components separately. The second model was bi-objective cost minimization based on the priority weights of the two costs. It was designed to determine minimum transportation costs based on priority weights. Model testing was carried out through numerical experiments on several cases that often occur in industries in Maluku, Indonesia, especially tourism and goods shipping. Each case has variations in the number of islands and nodes. As a result, the model can demonstrate its adaptability to changes in objectives and parameters. For cases that do not have a single solution, an increase in the network structure on the number of islands and nodes will increase the variety of efficient alternative solutions. The set of efficient solutions also shows an inverse relationship between MTC and GTC. The results also show that MTC minimization cannot be used as a reference for TC minimization in cases with many nodes and islands. Efforts to minimize MTC in the island zone impact reducing total costs but do not mean minimizing total costs. In addition, based on the exponential trend line of computing time, the number of nodes has a more significant influence on computing time compared to the number of islands.

“…The network systems discussed in this study intersect with ship routing problems or insular vehicle routing problems [8][9][10], hub location routing problems [11], and covering or facility location problems [12]. However, it is rare for articles to specifically discuss the efficiency of multi-cluster food distribution networks in the island zone, especially the Moluccas.…”

This study aims to design a route optimization model to support commodity distribution in the Moluccas archipelago zone. The model is designed using an integer programming approach for multi-depot multi-cluster with the aim of minimizing distance. In this case, several points on the island must be serviced. Each service point will only choose one port to serve. Sea transportation routes are formed from selected port nodes with a ring-ring-star hierarchical structure. A model designed to complement transportation routes in meeting the demand for service points by considering local, regional and global route distribution. Each level route will select one or more depots which will represent set to the top route level. The model is applied to several scenarios to see the best distance recommendations from island sample characteristics and point and island sizes.

Municipal solid waste management (MSWM) requires significant planning and objective definitions of each of its stages. Waste collection and transportation stages are of utmost importance, and they represent a significant cost of the process. In this context, a systematic study using bibliometric analysis was conducted, seeking to identify and understand the applied methodologies and tools, as well as which parameters and approaches are employed to optimize the solid urban waste collection system. The analysis portfolio features 12 publications, focusing on the optimization of municipal solid waste (MSW) collection systems, mostly with the aim of optimizing routes for transporting waste from the collection points to the final destination, with the goal of reducing the costs of this stage. Results highlight how these studies only consider as optimization criteria the reduction of the travelled distance and lack other dimensions (such as an environmental impact perspective). Some of the studies demonstrate the vital role of technology in optimizing the waste collection operation, from the use of geographic information systems (GIS) to using sensors or smart bins. Future research efforts should widen the scope of what is considered in optimizing the waste collection system.
