The existing Data Envelopment Analysis models for evaluating the relative eciency of a set of decision making units by using various inputs to produce various outputs are limited to crisp data in crisp production possibility set. In this paper, rst of all the production possibility set is extended to the fuzzy production possibility set by extension principle in constant return to scale, and th...

In the era of sharing economy and mobility-as-service, last mile delivery system is undergoing revolutionary changes with emerging a lot new operation modes policies. The crowdsourced mode has become novel popular practice in industry. This brings way for facilitating efficiency on basis shared mobility. paper studies an open vehicle routing problem (OVRP) mobility based mode, which parcel orde...

The eigenvalues and eigenvectors of the Fisher Information Matrix (FIM) can reveal most least sensitive directions a system it has wide application across science engineering. We present symplectic variant eigenvalue decomposition for FIM extract sensitivity information with respect to two-parameter conjugate pairs. approach decomposes onto an even-dimensional basis. This structure additional b...
