需要と供給
Corporations manage their supply chain to take advantage of cheaper costs of production. A supply chain is a system of organizations, people, activities, information, and resources involved in moving a product or service from supplier to customer. Supply chain activities involve the transformation of natural resources, raw materials, and components into a finished product that is delivered to the end customer. Supply chains link value chains. Supply and demand can be very fickle, depending on factors such as the weather, consumer demand, and large orders placed by multinational corporations.
