Abstract

Abstract: An intelligent boom sprayer (IBS) can realize efficient, precise and variable pesticides spraying operations on diverse crops and terrains by reconfiguring its hardware/software modules. Therefore, an ecological and reconfigurable design development strategy for IBS to get design goals, such as detachability, recyclability, maintainability, and reusability, will play a key role in ensuring the functions, service life and quality requirements of the product. After analyzing connotation and features of IBS, the Brownfield Process (BfP) was optimized to construct a Preferable Brownfield Process (P-BfP) which could achieve IBS ecodesign goals through analyzing the applicability and interference of IBS design and using Axiomatic Design (AD) as a main optimization theory role. The content identification and communication mechanism of the P-BfP were studied. The importance of existing resource reuse and standardization in the product design process for ecodesign was also highlighted. Dynamic models of BfP and P-BfP were built by using System Dynamics (SD) for providing a method to optimize the P-BfP design process. The simulation results showed that the P-BfP is more suitable for IBS design than the BfP from the time dimension by applying Vensim PLE and can improve the operating efficiency by 40% and reduce the training time by 50% while scientifically guiding the development of IBS. Finally, the feasibility of P-BfP was illustrated through comparing boom structure development result. The research results provide valuable scientific guidance for the ecodesign of reconfigurable modular products like IBS.
