A design problem of cross-docking distribution networks is addressed as a new research area in logistics management. This paper presents a new mathematical model for the location of cross-docking facilities and vehicle routing scheduling problems in distribution networks. For this purpose, a two-phase mixed-integer programming (MIP) is formulated. Then, a new heuristic-based simulated annealing...

This paper addresses a reliable facility location problem with considering facility capacity constraints. In reliable facility location problem some facilities may become unavailable from time to time. If a facility fails, its clients should refer to other facilities by paying the cost of retransfer to these facilities. Hence, the fail of facilities leads to disruptions in facility location dec...

Currently, users’ location information is collected to provide better services or research. Using a central server collect, store and share has inevitable defects in terms of security efficiency. the point-to-point sharing method will result high computation overhead communication for users, data are hard be verified. To resolve these issues, we propose new blockchain-based multi-level secure s...
