Storage efficiency of the automated storage and retrieval system (AS/RS) is well known by its high storage efficiency, the advantages of automation and high level of information, its operating efficiency has also become the focus of attention. This paper tries to take an automated storage and retrieval system of one manufacturing enterprises for example, analyzing the overall process and detailed steps. Then, Flexsim is used to identify its bottlenecks by providing system. At last, measures are used to optimize the operating efficiency.

Blockchain system store transaction data in the form of a distributed database where each peer is to maintain an identical copy. Blockchain systems resemble repetition codes, incurring high storage cost. Recently, distributed storage blockchain (DSB) systems have been proposed to improve storage efficiency by incorporating secret sharing, private key encryption, and information dispersal algorithms. However, the DSB results in significant communication cost when peer failures occur due to denial of service attacks. In this project, we propose a new DSB approach based on a local secret sharing (LSS) scheme with a hierarchical secret structure of one global secret node and several local secret nodes. The proposed DSB approach with LSS improves the storage and recovery communication costs.
