The Delight Design Platform Project is managed by The University of Tokyo as part of the Crossministerial Strategic Innovation Program (SIP) which is organized by Cabinet Office, Government of Japan. This project recommends using 1DCAE design tools in the concept phase of the product development. In the Delight Design Platform, new product concepts are simulated and evaluated as 1DCAE models. O...

Cross-efficiency evaluation is an effective approach to ranking decision making units (DMUs) that utilize multiple inputs to produce multiple outputs. Its models can usually be developed in a way that is either aggressive or benevolent to other DMUs, depending upon the decision maker (DM)’s subjective preference to the two extreme cases. This paper proposes several new data envelopment analysis...

In order to have a sustainable economic and social development, it is important balance growth ecological environmental damage. this article, we used the resampling model under triangular distribution evaluate energy efficiency, because input/output value may measurement errors, time lag factors, arbitrariness, other problems, causing their own DMU change. After these factors were taken into co...

In this paper, we will propose a Slacks-Based measure (SBM) of efficiency in DEA. This scalar measure deals directly with the input surplus and the output shortage of the decision making unit (DMU) concerned. It is unit invariant and monotone decreasing with respect to input surplus and output shortage. Furthermore, this measure is decided only by consulting with the reference set of the DMU an...

In measuring the overall efficiency of a set of decision making units (DMUs) in a time span covering multiple periods, the conventional approach is to use the aggregate data of the multiple periods via a data envelopment analysis (DEA) technique, ignoring the specific situation of each period. This paper proposes using a relational network model to take the operations of individual periods into...
