This paper investigates the interactions between content creators and viewersin donation-based live streaming platforms. In these social media systems,creators produce their content, while viewers enjoy the live streaming and decide to donate money to creators, making decisions to contribute financial support to the creators. To capture the sequential decisionprocess of the model, we introduce a multi-leader-follower game, inwhich creators act as the leaders of the game and viewers as the followers. Creators first optimize their performance level and the duration of the streams to maximize their profit. Then, viewers optimize the time spent watching a live stream to maximize their utility. Thus, the first stage of the game models thenon-cooperative competition among creators, while the second stage represents the behaviour of viewers deciding on their content demands.We formulate these stages as Nash equilibrium problems, and then as variational inequalities. We analyze the existence and uniqueness of the Stackelberg equilibrium. Then, we derive a supervised learning algorithm to estimate the parameters of the Artificial Neural Network model, focused on the advertisement function to properly verify the proposed model in a realistic setting.

“…The supply chain network, consisting of a fleet of F 3 UAVs (divided in two sets: F1 = { 1, ..., f , ..., F1 }, the set of pre-existing UAVs and F2 = { 1, ..., f , ..., F2 }, the set of possible additional UAVs, where F 3 = F1 + F2 ), D controller UAVs and U users or devices on the ground, is depicted in Figure 1 (see [3] for another optimization model based on supply chain network, [2] and [10] for other optimization models on closed-loop chains, and [14] for digital data sharing across the supply chains). The typical user or device on the ground is denoted by u, and could require S types of network or application services.…”

In this paper, we present a network-based optimization model describing a closed-loop supply chain for the provision of 5G network slices on demand to users and devices on the ground. The three-tier supply chain network consists of a fleet of pre-existing UAVs, to which others can be added, managed by a fleet of UAV controllers, whose purpose is to perform services requested by users and devices on the ground. The aim of this paper is to provide a constrained optimization problem through which the providers’ profits are maximized, determining the global optimal distributions of request flows, the global optimal distributions of executed services and the optimal reliability level of pre-existing UAVs of the fleet. We also derive the associated Variational inequality formulation of the problem and, finally, a numerical simulation is performed to validate the effectiveness of the model.

“…PengY analyzed the sensitivity of the demand market to service quality, the relative importance of improving service quality by service providers, and the impact on the equilibrium state of the supply chain network based on a three-level PSSC network structure composed of service providers, platform operators, and demand markets.He also established a PSSC network equilibrium model in 2023, considering the dual risks faced by products and services [22][23]. Fargetta G [24] argue that a supply chain logistics network involves both forward and reverse logistics competition. Xiao Y X [25] believe that in a highly integrated supply chain system, the balance between after-sales service and product quality becomes an important consideration for establishing and maintaining sustainable supply chain partnerships.…”

Introducing Third-party logistics into the supply chain of fresh agricultural products can reduce the logistics cost of the supply chain and improve the freshness and quality of fresh agricultural products. Taking the fresh agricultural product supply chain network, which includes three decision-making entities: fresh agricultural product suppliers, 3PL service providers, and retailers, as the research object, a fresh agricultural product supply chain network equilibrium model is constructed using variational inequality theory. The impact of 3PL service providers' logistics service level on their equilibrium transaction volume and overall profit is studied. The research results show that when Third-party logistics is involved in the supply chain of fresh agricultural products, considering the logistics service level of 3PL service providers, with the improvement of service level, the overall profit of the supply chain of fresh agricultural products increases. It is a beneficial attempt to realize the profit of the supply chain of fresh agricultural products to improve the freshness and quality of fresh agricultural products through Third-party logistics; When the logistics service level rises to a certain level, and the service level continues to improve, the overall profit growth of the supply chain decreases. It is necessary to improve the impact of logistics service level on the freshness and quality of fresh agricultural products through other forms.
