Abstract: The increasing number of variants in manufacturing companies’ product ranges leads to rising costs due to process and product complexity. The expected profit of higher diversity is often overrated while its costs are underestimated because of missing methods and insufficient process transparency. This paper introduces a methodical approach to identify the optimal diversity considering available capacities and the effects on profit and costs for each variant to support variant decisions within the product and process planning. Therefore a mathematical model of the described diversity planning problem is developed. This complex decision problem is solved using a particle swarm algorithm, which is able to compute the optimal solution within reasonable time. The found solutions can be discussed and evaluated by an interdisciplinary planning team considering even qualitative aspects, leading to an increased transparency in the decision process.
