Stochastic inventory management has been extensively explored for more than eight decades, where a number of studies focus on the structure of optimal inventory policies under the periodic-review setting. It turns out these structural results significantly depend on properties of the production cost functions, e.g., with or without fixed cost, capacity limit, diminishing margin and etc., which are usually characterized by convex-like properties, e.g.,  K-convexity, CK-convexity and concavity and etc. This work introduces two convex-like concepts and analyzes the structure of the optimal inventory policies. The first one extends almost all known similar concepts in literature and helps us to develop a uniform framework on related structural results. The second one is weaker yet leads to an elegant preservation result close to the regular convexity, and hence provides a powerful tool to analyze the performance of heuristics for more general cost functions.
