The 3D planning software EMA offers a combined approach which takes into account the factory planning level and the detailed planning at the single work station level. Ema Work Designer supports digital production planning, prospective ergonomics and productivity assessment by providing a more efficient and accurate approach to 3D human simulation of manual and semi-automatic tasks at the micro level. Additionally, the new module EMA Plant Designer allows to include entire factories and production lines for evaluation of lead time, production costs, material flow, buffer position, space and layout at the macro level. An application example shows that ergonomic and productivity design don’t contradict each other, if they are considered early in the design phase in one common software system. Many practical experiences suggest that this approach facilitates cooperation between different business units that are traditionally separated, such as factory/facility planning, manufacturing engineering, industrial engineering, production, and health & safety.
