Abstract: We study the coordination between pricing and production scheduling decisions of a manufacturer who quotes prices for a set of order inquiries. Each inquiry is either canceled or confirmed by its owner following a certain probability distribution that depends on the quoted price. The manufacturer then incurs a production scheduling cost for processing each firm order. Two types of price quotation schemes, simultaneous and sequential quotations, are investigated. A simultaneous quotation quotes all order inquiries simultaneously. We formulate the problem with a special form of price function as a quadratic program that can be solved efficiently. Properties of optimal quotations are provided. A sequential quotation quotes order inquiries one at a time. For the problem, we develop optimal algorithms using implicit enumeration, and design efficient heuristics. Through computational studies, we compare simultaneous and sequential quotations and provide several managerial insights. We also recognize conditions under which simultaneous quotation performs close to sequential quotation, and conditions under which  heuristic sequential quotation performs near optimal.
