摘要：
One of the main results of Order-Based Cost Optimization in Assemble-toOrder Systems [Lu Y, Song J-S (2005) Order-based cost optimization in assemble-to-order systems. Oper. Res. 53(1):151-169] is proposition 1(c), which states that the cost function of an assemble-to-order inventory system satisfies a discrete convexity property called L-(sic)-convexity. We construct a counterexample showing that this result is incorrect, and hence their proposed steepest decent algorithm may not work.
