Abstract
Purpose
This study aims to develop an analytical model for generating relational rent within network organizations and to establish a comprehensive framework for the allocation of such rent.
Design/methodology/approach
The design stage involves the formulation of integrated computer-aided manufacturing definition (IDEF0) methodologies. The construction stage comprises the detailed elaboration of three distinct stages for rent allocation methods.
Findings
The “relational rent” perspective has illustrated that firms create value and distribute rent within network organizations by identifying partners with complementary resources, establishing high levels of robust informal trust, sharing knowledge and making customized investments tailored to their partners’ needs.
Practical implications
This innovative approach, for the first time, sheds light on the path for managers to secure the stability of network organizations by implementing multiple iterations of benefit distribution. However, it remains an area lacking standardized guidelines for decision-makers. Essentially, our paper pioneers the endeavor, marking the inaugural step toward ensuring network organization stability through profit distribution decisions. Additionally, it constitutes the initial attempt to bridge the gap between qualitative analysis and a quantitative profit distribution framework.
Originality/value
This rent allocation method unequivocally highlights the importance of efficient allocation within network organizations, emphasizing the streamlining of the allocation process and thus substantiating the rationality of the proposed method.

Abstract
Purpose
The purpose of this paper is to discriminate fake interference caused by polygonal approximation so as to achieve accurate assembly sequence planning and assembly simulation.
Design/methodology/approach
An approximation zone model is proposed to formulate polygonal approximation. Fake interference is discriminated from hard interference by evaluating if polygonal models intersect within corresponding approximation zones. To reduce the computation, the surface-surface, surface-end face and end face-end face intersection test methods have been developed to evaluate the intersection and obtain collision data. An updated collision detection algorithm with this method is presented, which is implemented by a system named AutoAssem.
Findings
This method has been applied to a set of products such as a valve for assembly interference matrix generation, static and dynamic collision detection. The results show that it ensures the accuracy of assembly sequence planning and assembly simulation for polygonal models.
Practical implications
This method facilitates assembly design in the virtual environment with polygonal models. It can also be applied to computer aided design systems to achieve quick and accurate collision detection.
Originality/value
Fake interference between polygonal models may result in serious errors in assembly sequence planning and assembly simulation. Assembly zone model and novel polygon intersection verification methods have been proposed to effectively tackle this problem. Compared to current methods, this method considers valid penetration direction and approximation difference, does not need to process complicated auxiliary data and can be easily integrated with current collision detection methods.

Abstract
Purpose
Alternating current (AC) corrosion is a type of corrosion that occurs in buried pipelines under AC stray current interference, which can increase the hydrogen embrittlement sensitivity of pipelines. However, rare research works have been conducted on the hydrogen permeability characteristics of pipeline steel under AC stray current interference. The purpose of this paper is to study hydrogen permeation behavior of X80 steel under AC stray current interference.
Design/methodology/approach
In this paper, the hydrogen permeation behavior of X80 steel under AC interference is studied by AC hydrogen charging experiment in a dual electrolytic cell. The relationship between hydrogen evolution rate and hydrogen permeation flux is studied using the gas collection method. The difference between AC hydrogen permeability and direct current (DC) hydrogen permeability is also discussed.
Findings
The anodic dissolution caused by AC corrosion promotes the chemical desorption reaction of the adsorbed hydrogen atoms on the surface, reducing the hydrogen atom absorption ratio by 70%. When the AC is smaller than 150░ A/m2, the hydrogen permeation process is controlled by the hydrogen atom generation rate, and the hydrogen permeation flux increases with the increase in hydrogen atom generation rate. When the AC exceeds 400░ A/m2, the hydrogen permeation process is controlled by the absorption ratio. The hydrogen permeation flux decreases with the decrease in the absorption ratio. Under AC interference, there is a maximum hydrogen permeation flux that linearly correlates to the H+ concentration in the solutions.
Originality/value
The high-strength steel is very sensitive to hydrogen embrittlement, and X80 steel has been widely used in oil and gas pipelines. To date, no research has been conducted on the hydrogen permeation behavior of pipeline steel under AC interference, and the hydrogen permeability characteristics of pipeline steel under AC interference are not clear. The research results of this paper are of great significance for ensuring the intrinsic safety of high-strength pipelines under AC stray current interference.
