“…Some researchers believe that the flow analysis of a system must combine the functions of the system components and make full use of the resources available in the system and the super-system [7], [20], [24]. Therefore, based on the functional analysis [25]- [27] and resource analysis in the TRIZ theory [24], the establishment of a flow problem analysis model that is suitable for the system flow analysis [7] is the prerequisite for determining the system flow problem.…”

Frequent processes of mutual transfer and transformation generally take place between the material flow, the energy flow, and the information flow in complex engineering systems, and complex coupling relationships exist between the different flows. Abnormal coupling of flows will cause flow problems, which can easily lead to the failure of the system functions. To address these problems, in this study, the starting point has been taken as the change in the attributes and types of the study flow, the attributes of the flows have been categorized, and a flow transfer and transformation model, oriented to the flow problem analysis has been proposed. Secondly, based on the analysis of the effect of the attribute changes of flows in complex engineering systems on the generation of flow problems, an innovatively introduced information processing mathematical tool, the polychromatic sets theory, has been used to explore and determine the flow problems existing in complex engineering systems. Further, depending on the different manifestations of flow problems, three solution strategies have been proposed. Finally, the process model of the flow problem judgment and a solution strategy for complex engineering systems has been constructed. The feasibility of the process model has been verified by considering the engineering case of the tubular feeding machine (TFM) system of a large-scale integrated marine resource survey ship.INDEX TERMS Complex engineering system, polychromatic sets, flow problem judgment, solving strategy, tubular feeding machine (TFM) system.

“…At present, case knowledge is vital. The TRIZ has been proven effective, and it has been widely used in the conceptual design of industrial equipment and customized products (Guo et al, 2016;Guo et al, 2021;Li et al, 2018). Scheme evaluation and decision-making are important in judging the degree of consistency between FRs and CSs.…”

“…To help designers complete the conceptual design synthesis of simple design tasks or the synthesis results of the string parallel structure of the basic functional modules of complex design tasks. Guo et al [12] proposed an approach to support resilient conceptual design using functional decomposition and conflict resolution to address the question of how to design resilient product structures to meet more functional requirements during the conceptual design phase. Cao et al [13] proposed a model-driven software and physical parallel concept design method based on SysML, which realized the parallel design of software and physical subsystems in the conceptual design stage of complex electromechanical systems.…”

This paper presents a conceptual product design method that considers the carbon emission factors of mechanical and electrical products, with the purpose of considering low carbon issues before designing products. Based on a comprehensive analysis of conventional product design procedures, the study extracts design information related to greenhouse gas emissions, itemizes and quantifies the information, and ultimately uncovers the relationship among carbon emissions, function and cost of newly designed products. This paper explains the proposed concepts of carbon efficiency and carbon factor, and combined them with the product design process to present a low-carbon design process of mechanical and electrical products. Furthermore, this paper presents a low-carbon design method of mechanical and electrical products, drawing on the product family design idea, with the GHG efficiency and cost constrained. The potential value of the method is demonstrated in a case study of a tomato picking robot.
