The 'manufacturer-internal relationship optimization model (MIROM)', a schematic framework for internal relationship, is proposed for the manufactured housing (MH) factory. This model emphasizes the relationship between customer order from retailers (i.e., customized MH) and the production process, indicating that these elements are not mutually exclusive. In particular, through surveys and site visits, the planning of the product mix and sequence in the MH factory is considered the most critical area of the MIROM framework. This paper aims to convey how these areas can be elevated to the planning level with innovative changes and optimization. A product mix optimization model with linear programming was developed and a sequence optimization model was created by incorporating just-in-time (JIT) approaches. The proposed strategic MIROM framework and the specific optimization models can contribute to achieving significant improvement in the internal MH production planning. It can be applied for the site-built housing industry with similar industrialized environments depending on the scale of the operation.
