Grey graphs and its application

In multi-attribute decision-making problems where the attribute values are interval grey numbers, a simplified form based on kernels and the degree of greyness is presented. Combining fuzzy graph theory with the kernel and the degree of greyness of interval grey numbers, grey graphs and their corresponding operation rules are presented. This paper presents a new multi-attribute decision-making method based on grey graph theory. We analyzed and evaluated the alternative schemes using grey graph. Lastly, a numerical example was conducted in order to demonstrate the effectiveness and feasibility of the proposed method.

AI Coding Tools and Digital Entrepreneurship: The Role of Software Expertise

While digital technologies expand entrepreneurial access by providing technical resources, it is less known whether they enable ventures to create durable value and whether they can substitute for technical expertise accumulated through software work experience. This paper studies how digital ventures respond to the wide diffusion of AI coding tools, and how these responses are shaped by founders' software expertise. Measuring product-category exposure to AI coding using pre-LLM product descriptions and linking venture launch, traffic, and financing data, we show that exposure to AI coding increases first-time venture launches after 2022Q4, while entrants are less likely to survive but raise more financing conditional on one-year survival. Crucially, founders with software work experience drive a larger fraction of new launches, ameliorate the decline in survival when product development is partially rather than fully automated, and explain all of the increase in venture financing.
