在本文中，我们提出了一些非径向，面向输出，集中DEA模型来确定个人和集体的产出目标水平，输入松弛和输入重新分配，以及额外的投入收购资本预算约束下。所提出的方法，以西班牙港务局的应用。目前在该系统中发现的低效率的总量允许确定潜在的总产量增加24%至114%，而无需额外资源。考虑到投入的重新分配将允许额外的20%的产出扩张。获得额外的投入资源将使进一步扩大产出成为可能，其确切价值单调地取决于所考虑的资本预算。
In this paper, we propose a number of non-radial, output-oriented, centralised DEA models to determine individual and collective output target levels, input slacks and input reallocations as well as additional inputs acquisitions under a capital budget constraint. The application of the proposed approach to the Spanish Port Agency is presented. The overall amount of inefficiency currently found in the system allows for the determination of potential total output increases ranging from 24% to 114% without additional resources. Considering inputs reallocation would allow for an additional 20% output expansion. The acquisition of additional input resources would make feasible to expand outputs further, to levels whose exact values monotonously depend on the capital budget considered.
