Abstract In this paper, a novel multi objective mathematical programing model is developed which focuses on enhancement of quality of design via optimizing the layout of components in multicomponent systems. The objectives include maximization of accessibility to components, optimization of distance between members based on their positive/negative interaction, maximal maintenance space inclusion around components and minimization of total volume of the system. The structure of the variables and constraints of the model is novel and assorts the formulation of the objectives. As a case study, the model is used to optimize the layout of components of a laser range finder. First, the model is converted to a single objective one via the weighting method and by using the eigenvalue approach. Then, the obtained model is solved via Lingo. Results demonstrate that the solution is close to the ideal solution by 82.7%. Moreover, accessibility (the most important objective) and maintenance distance requirement correspond 100% to their ideal value.
