Performance evaluation of efficiency change and productivity growth in Supply Chain Management

The performance of a supply chain can be evaluated in either a cross-sectional or a time seriesmanner, and data envelopment analysis is a useful method for both types of evaluation. in this paperwe develop an index and indicator of productivity change that can be used with radial and non-radialmodels for supply chain malmquist index. the supply chain malmquist productivity index (scmpi)can be decomposed into two components: one is measuring the technical change (tc) and the othermeasuring technical eciency change (tec). so that we propose a supply chain dea models thathave supplier-manufacturer structures.
