This paper constructs a multi-channel supply chain that includes manufacturer, dual-channel retailer and an online retailer. The has traditional channel channel, while the manufacturer cooperates with retailers opens direct simultaneously. horizontal historical price discount sensitivities are taken into account to establish price-sensitive demand functions. A game model heterogeneous expectations is proposed analysed methods of stability domain, bifurcation diagram maximum Lyapunov...

To investigate the roles of oxidative stress-related differentially expressed genes (OSRDEGs) in keloid formation and explore their potential value diagnosis treatment. Gene expression data from GEO database, including GSE145725 GSE44270 as training sets GSE7890 a validation set, were utilized. OSRDEGs identified, followed by Weighted Co-expression Network Analysis (WGCNA), GO/KEGG enrichment analysis, Set Enrichment (GSEA). Key further screened through protein-protein interaction (PPI)...

Nowadays, with more and people choosing energy-saving product, green supply chain is increasingly becoming popular. In this paper, we build a dynamic Stackelberg game model that contains government, two innovation enterprise which leader produces kinds of product similar function but different quality retailer selling meanwhile. We use classical backward induction to solve the model. Price decision considered first divided into stages. analyze equilibrium price stable region. Next, index...

Considering the trends of carbon tax and online retail market, a comparative study on order quantity strategy supply chain under two policies are conducted. A multichannel model is constructed in this work flat policy progressive policy. The complexity channel heterogeneity expectations studied. impacts consumers’ dual preferences free-riding each system complexity, profits, emissions social welfare explored. This indicates that types will enter into an unstable state with changes...

The game characteristics and equilibrium strategies of a triple-channel supply chain under the carbon subsidy policy are studied in this work with three different power structures. There simultaneous decision-making, manufacturer-dominated market retailer-dominated market. decision mechanism for order quantity manufacturer dual-channel retailer, is discussed. Meanwhile, their complex dynamic studied. It found that when government implements dual low-carbon subsidies, system which dominates...

At present, most of the manufacturers are increasingly laying emphasis on dual‐channel selling. The level consumer’s preference is diverse with different channels. This study discusses a supply chain where one common manufacturer uses two channels to sell product. bounded rationality expectation has been applied explore decision‐making mechanism in finalizing wholesale prices and sales commissions for retailers. In addition, dynamic features system simulated by 2D bifurcation diagram,...

This study investigates the dynamic game behaviors of dual-channel supply chains involving an oligopoly manufacturer selling low-carbon products to online and offline retailers. The price models under government subsidy are discussed three scenarios: (1) simultaneous decision, (2) dominates market, (3) retailer market. equilibrium strategies compared policy. Using numerical simulation, complex characteristics chain carbon policy investigated. complexity wholesale sales commission each...

This article adopts the method of Gray Markov to predict rainfall. GM (1, 1) model is used establish rainfall prediction with gray system composed over years. It poor fit for random and volatile data sequence; therefore, accuracy also low. However, chain can describe change dynamic system. mainly based on transition probability between different states subjects infer systems' future development. Because problem about changes time shows a trend non-stationary stochastic process. And it...

Nowadays, with global scientific and technological levels rapidly improving, innovation has been a great need for enterprises to solve the dilemma. Combined EPR (Extended Producer Responsibility) topic of remanufacturer, adopting green an effective way when supply chain management is applied. In this paper, we focus on activity build model where manufacturer will invest in improve product availability rate recycled products save cost process remanufacturing. Besides, take three stages cycle...

In this work, dual-channel supply chain price models and their optimal strategy were studied under government low-carbon innovative subsidies. The decision-making mechanism complex dynamical characteristics of manufacturer's wholesale retailers' sales commissions discussed. results showed that when the implements subsidy policy, change adjustment coefficient manufacturer, online offline retailers will lead to instability system, manufacturer has more influence on system than retailers....

For achieving the goals of carbon peaking and neutrality, government will further strengthen subsidies to enterprises for emission reduction. This paper investigates long-term repeated game behavior manufacturer retailer in multichannel supply chains under three different forms subsidies. The is studied green innovation subsidy model (IS model), production (MS model) sales (RS model). Under situations, excessive price adjustment can easily lead system instability sharp fluctuations profits....

In this paper, an explanation based on a power law between the average spectrum and spatial frequency is proposed to reinterpret three famous experiments primitive visual perception involving prior of global topological properties, form stability properties in apparent motion drosophila's characteristic transition invariance. Then, important found.

Visual Computational Theory that was founded by Marr plays an extraordinarily important role in Science. There is still lot of research to do for this theory, such as building it spatial frequency domain. Our will be mainly on theory domain and application the which simulation dynamic radiated fringes.

The supplementary water volume was researched when the reclaimed taken as supplement of landscape lake on premise quality standard. According to analysis problems using water, a improved model caculate environmental capacity established. Then proved by experiment. A certain amount injected in cattail tank simulate real which supplemented with water. dissolved oxygen, ammonia nitrogen, temperature and pH were monitored every 2 hours during day. multiple linear regression method used calculate...
