摘要：Product service system is a new-type production system with high-degree integration and overall optimization of prod?uct and service. The participation of suppliers in product service system development will greatly shorten the develop?ment cycle and enhance the production efficiency. The task planning of product design is one of the key phases of product service system development process, which mainly contains the design task decomposition and the design task allocation. Aiming at product service system product design, this article conducts the decomposition of design tasks, per?forms the recognition of coupling design task set, and realizes the structured modeling of design tasks. Outsourcing decision-making analysis is conducted on the design tasks obtained through decomposition process so as to confirm the design tasks that need the participation of suppliers. The allocation model of design tasks is constructed, and the suppli?ers that take part in product service system development are confirmed based on genetic algorithm. Taking the numeri?cal control machine tool as an example, this article conducts the instance analysis and verifies the feasibility of the forenamed methods.
