Pricing Decisions of a Dual-Channel Supply Chain considering Supply Disruption Risk

Supply disruption may cause strong complaints of customers, which is a cost loss for the firms in the supply chain. Obviously, if realizing that there is the disruption risk, the members in a supply chain will adjust their decisions. For analyzing the influence, we consider a popular supply chain mode with dual channels, where one manufacturer has its direct sales channel and one traditional retailer channel. The manufacturer may suffer a supply disruption so that all ordered products by the retailer or the direct retail channel will be lost, and the members in supply chain will bear the corresponding disruption penalty from the customers. By considering four structures with different market power relations, the closed-form optimal price decisions of the four models are given. We found that the disruption factor improves the sales prices for any member structure as compared to the supply chain without the disruption. And the direct retail prices in the different modes are the same as each other, but the price of the traditional channel is influenced by the market share. And the sorts of the sales prices under different structures are given. We also conduct some extensive numerical analysis and compare the results under different structures. We observe that the expected optimal profits of considering the external penalty are smaller than those of no external penalty, and we give a sort of the optimal expected profits. And we also provide the effects of some parameters on the optimal decisions and the optimal expected profits

Information sharing through digitalisation in decentralised supply chains

This study investigates the impact of private information on decision making process and how emerging technologies can facilitate information sharing and reduce misinformation in decentralised settings. Focusing on business environments, we examine if information sharing between distinct partners can be a mutually beneficial option. In principle, information affects the preferences and the actions of decision makers and usually contributes to inefficiencies for the entire system. A supply chain with two rational firms is considered; the firms have conflicting objectives and possess information that cannot be verified. Real-time communication through a cloud platform is allowed, before the firms finalise their strategies. During the communication phase, both firms are free to report whatever information optimises their individual objectives, even fake. Misinformation seems a plausible option, especially in competitive environments, since the firms may take advantages from such behaviour. We demonstrate that sharing the actual information can be beneficial for both, under the implementation of an appropriate mechanism that considers the welfare of the entire chain. Despite the individualistic behaviour of independent decision makers, it is doable to eliminate entirely information asymmetry and misinformation. This happens by including sufficient incentives on a mechanism that induce firms to reveal their information, because it is in their self-interest to do so. The value of information and the expected benefits of the voluntary information sharing are calculated, indicating the potential improvement

Optimal Policies on Managing Drug Supply and Patient Access to Drugs

Health care decision-makers face several uncertainties regarding pharmaceutical products. For new and expensive drugs, the performance outside of clinical trials could be uncertain. For old and low-profit pharmaceutical products, the supply could be uncertain, causing drug shortages. In three essays, I study mitigating strategies to deal with different types of uncertainties associated with pharmaceutical products. In the first essay, I compare two types of pharmaceutical reimbursement contracts to mitigate the uncertainties associated with new and expensive drugs. I construct a game-theoretic model to analyze the interactions between a pharmaceutical manufacturer and a payer. The payer’s reimbursement of a drug is either related to the cost-effectiveness or the sales volume of the drug in the two contracts, respectively. I find key factors that determine the two parties’ preferences for the two contracts. I also find conditions under which each type is preferred by both parties and can achieve a Pareto improvement. In the second essay, I study mitigating strategies for drug shortage, which has become a serious problem in many countries in recent years. I construct a multi-period supply chain model to analyze the interactions between a representative hospital and an unreliable pharmaceutical manufacturer. The hospital owns an in-house manufacturer and can procure the drug from the two manufacturing facilities. I also assume that the hospital can make emergency production. I study the two parties’ procurement and production decisions and examine the impacts of the hospital’s optimal decisions on the external manufacturer’s profit. In the third essay, I study mitigating strategies for drug shortages from the governments’ perspective. I construct a game-theoretic model consisting of a pharmaceutical manufacturer, a wholesaler, and a government. I compare two types of mitigating strategies that the government can implement: providing subsidies to the wholesaler, or using a government-owned manufacturer. I identify key factors for the government’s preference over the two strategies and examine the impact on the private sector. The three essays have theoretical contributions to game theory and supply chain risk management literature and have policy implications for policymakers to manage drug supply and patient access to drugs

Sustainable supply chain management towards disruption and organizational ambidexterity:A data driven analysis

Balancing sustainability and disruption of supply chains requires organizational ambidexterity. Sustainable supply chains prioritize efficiency and economies of scale and may not have sufficient redundancy to withstand disruptive events. There is a developing body of literature that attempts to reconcile these two aspects. This study gives a data-driven literature review of sustainable supply chain management trends toward ambidexterity and disruption. The critical review reveals temporal trends and geographic distribution of literature. A hybrid of data-driven analysis approach based on content and bibliometric analyses, fuzzy Delphi method, entropy weight method, and fuzzy decision-making trial and evaluation laboratory is used on 273 keywords and 22 indicators obtained based on the experts’ evaluation. The most important indicators are identified as supply chain agility, supply chain coordination, supply chain finance, supply chain flexibility, supply chain resilience, and sustainability. The regions show different tendencies compared with others. Asia and Oceania, Latin America and the Caribbean, and Africa are the regions needs improvement, while Europe and North America show distinct apprehensions on supply chain network design. The main contribution of this review is the identification of the knowledge frontier, which then leads to a discussion of prospects for future studies and practical industry implementation

Application of Optimization in Production, Logistics, Inventory, Supply Chain Management and Block Chain

The evolution of industrial development since the 18th century is now experiencing the fourth industrial revolution. The effect of the development has propagated into almost every sector of the industry. From inventory to the circular economy, the effectiveness of technology has been fruitful for industry. The recent trends in research, with new ideas and methodologies, are included in this book. Several new ideas and business strategies are developed in the area of the supply chain management, logistics, optimization, and forecasting for the improvement of the economy of the society and the environment. The proposed technologies and ideas are either novel or help modify several other new ideas. Different real life problems with different dimensions are discussed in the book so that readers may connect with the recent issues in society and industry. The collection of the articles provides a glimpse into the new research trends in technology, business, and the environment
