Let's consider the problem of maximizing profits by setting prices, as discussed in class. Suppose the demand curve is now represented by the equation: Demand = 700 - 5 * Price. Unit cost is $40. What would be the optimal price in this scenario? - โ โ 90
Let's consider the problem of maximizing profits by setting prices, as discussed in class. Suppose the demand curve is now represented by the equation: Demand = 800 - 7 * Price. What would be the optimal price in this scenario? - โ โ 77.
Which of the following listed below could potentially serve as a constraint in a linear programming problem? - โ โ 5x-7y<
What is the primary purpose of using models in organizations, especially in supply chain management? - โ โ To develop a better understanding of practical situations by representing them in a simplified form and predicting outcomes based on inputs.
What is the primary difference between direct operations and consolidated operations within the transportation context? - โ โ Direct operations are similar to a taxi service where cargo is taken directly from origin to destination, whereas consolidated operations are akin to mass transit service with shared transport and potential vehicle changes.
What are some key challenges and considerations in long-distance supply chains involving multimodal transportation, as illustrated by the shipment of a T-shirt? - โ โ Managing numerous vehicles and skilled operators, dealing with delays due to inspections and audits, and the economic considerations of freight vehicle operations.
When talking about supply chain disruption, what is the implication of describing links in a supply chain as 'keystones'? - โ โ The statement implies that almost every link in a supply chain is vital, and the disruption of any link can impact the entire system.
What are the complexities and challenges in assessing the sustainability of products throughout their supply chain, particularly in terms of carbon footprint? - โ โ Assessing sustainability involves understanding the entire life cycle, including raw material sourcing, production, consumer use, and disposal, with complexities like the carbon footprint of local versus long-distance sourcing.
What are the dual impacts of global trends on the workforce within supply chains? - โ โ The trends will result in some workforce displacement by technology, while also creating new tasks, roles, and jobs, and sustaining the need for human roles in design, management, and execution of supply chain activities.
What is a major limitation of many current deep learning AI systems? - โ โ They act like 'black boxes', offering answers without explanations for their decisions.
What is a digital twin and how is it used in the context of supply chains and business environments? - โ โ A detailed, digital replica of a physical system, continuously updated with real data, used for operational, performance improvement, and strategic purpose.
