| Summary: | This study examines a multi-product fish production and distribution system in which multi-fish products are produced simultaneously from a wide range of raw resource classes. The objective of environmentally sustainable production planning is to meet market demand in accordance with environmental constraints. This paper sets out a management model that converts fisheries into multiple marine objects and moves them to various dispensing centers. It also incorporates a model to improve production and distribution planning at the same time. The problem is formulated as a mixed integer programming model. Then, we addressed a strategy of releasing non-basic variables from their bounds to force basic non-integer variables to take integer value. As an implementation, we solved a fish production planning problem faced by an industry located in Kisaran city, North Sumatra province, Indonesia.
