رقابت خدمات پس از فروش در یک زنجیره تامین : بهینه سازی سطح رضایت مشتری یا سود و یا هر دو ؟

For durable consumer products, after-sales services play an important role in customers’ purchase decisions. A manufacturer offers basic warranty available to all customers who buy the product, while a retailer offers optional after-sales service that is available only to customers who pay for the option.
