Formation and Optimization of Operational Strategy Across Product Life Cycle Stages in Industrial Enterprises

This study focuses on the adaptive management of operational strategy and the optimization of resource allocation across Product Life Cycle (PLC) stages in industrial enterprises. Diverging from traditional single-factor and marketing-oriented PLC models, this paper introduces the concept of "Product-Commodity" duality. By integrating the production volume growth rate and working capital turnover duration, an 8-stage iterative operational matrix and its algorithmic model were developed. The core scientific novelty lies in formulating a mathematical framework to minimize the technological gap time during the transition between legacy and new products, effectively eliminating cumulative idle losses. Furthermore, the research proves the potential for generating additional cumulative operating profit and synergistic resource-saving effects during the decline phase through servitization and resource recirculation. The resulting conclusions and practical recommendations enable industrial enterprises to achieve operational continuity and maximize resource efficiency.
