In large organizations with a centralized decision-making environment like supermarket chains, selling or producing products usually involves participation of all individual units. Motivated by a production-planning problem regularly faced by the central decision-making unit of such an organization, this paper attempts to arrange new input-output plans for all units in the next time period when demand changes can be forecasted. The so-called central unit is assumed to be interested in maximizing the total net profits earned by all individual units. A new approach is developed based on data envelopment analysis to find the most preferred plans. All these individual units are supposed to be able to modify their inputs and outputs in the original production possibility set under certain conditions. The planning process is simple and widely applicable, which could act as a reasonable reference for decision makers. A simple numerical example and a real world application are given to illustrate the idea.
