Abstract

This paper presents a joint production, pricing and inventory control problem that can help manufacturers manage revenue in an omnichannel environment. The paper puts forward a multi-period Stackelberg game between a manufacturer and a retailer, assuming the former to be the leader. The leader– follower game is formulated as a mixed-integer non-linear bilevel optimization problem wherein both players seek to maximize their respective profits. The manuscript envisions an omnichannel retailing environment where online, offline, direct and drop-shipping channels coexist. It then investigates how enabling showrooming and webrooming on the drop-shipping channel account can affect supply chain profitabilities. Analyses suggest that when customers are aided with showrooming and webrooming services and are allowed to place drop-shipping orders from retailers’ stores, additional profit can be generated in the supply chain. To solve the proposed bilevel optimization problem, we investigated a) single-level reduction using Karush–Kuhn–Tucker (KKT) conditions and b) hierarchical optimization technique based on Simulated Annealing and Randomized Decomposition Solver. To assess the efficacy of the solution techniques, a comparative analysis was carried out. Thereafter, with the aid of numerical experiments and sensitivity analyses, the paper draws key managerial insights for manufacturers.
