DFX Platform for life-cycle aspects analysis

“Design for X” is commonly regarded as a systematic and proactive designing of products to optimize total benefits over the whole product life span (fabrication, assembly, test, procurement, shipment, delivery, operation, service, disposal), and meet target quality, cost, performance and time-to-market. DFX involves different methodologies for product design and optimization (like Design for: Manufacturing, Assembly, Variety, Serviceability, Environment, Reliability, Utilization, etc.), which provide useful results, however, they address only specific aspects of product life-cycle. In addition, various perspectives for business economics can often drive to contradicted conclusions, what makes the evaluation of both technical feasibility and product profitability more difficult. In this paper the framework for DFX analysis was proposed. In the described solution, the various product life-cycle analysis strategies are integrated, and profit calculations relay on common denominator – the present value of net benefit. This approach allows covering of all phases of a product life cycle not excluding e.g. complex environmental aspects. Based on the proposed framework, the DFX Platform was developed and implemented as a web service. The application of the system to a few product developments carried out within crossbordered manufacturing company showed its big positive impact on projects and their results.
