In real dispatch problems for bulk cement ships, input data or parameters are often imprecise or fuzzy. This study investigated the cement bulk carriers’ assignment problems, considering multi-products, multi-stations and multi-vessels. This study presents a novel fuzzy multi-objective linear programming (FMOLP) model that solves the bulk cement ship-dispatch problem in a fuzzy environment. This model is applied to solve multi-product, multi-ship and multi-silo ship-dispatch problems with imprecise goals, input data and parameters. It also elucidates the relationship between dispatch planning and cement silos, with a focus on the allocation of bulk cement ships. This study uses a cement study case to demonstrate the feasibility of the proposed model. Analytical results can help dispatchers systematically analyze the bulk cement ship-dispatch planning in practical applications.
