Within this context, the single allocation incomplete p-hub median, the incomplete hub location with fixed costs, the incomplete hub covering, and the incomplete p-hub center network design problems are defined, and efficient mathematical formulations for these problems with O(n3) variables are introduced.
To improve the provided service level of these networks, service time requirements are here considered during modeling, giving rise to a multiple allocation incomplete hub location problem with service time requirements.
This paper focuses on a multiple allocation incomplete hub location problem in which a hub network can be partially interconnected by hub arcs, direct connections between non-hub nodes are allowed, and uncertainty is assumed for the data of origin-destination demands and hub fixed costs.
There was, therefore, no risk of bias regarding sequence generation, allocation, incomplete or selective outcome reporting.
Most trials provided incomplete information on allocation concealment, blinding of participants and personnel, and blinding of outcome assessment.
It is possible that some of this effect is a result of bias introduced by incomplete concealment of allocation or unblinded outcome assessment, as opposed to a true effect of the video decision aid.
All of the RCTs reported incomplete outcome measures and allocation concealment.
These are considered under the following headings: allocation, blinding, incomplete data, and selective reporting.
15 We assessed the following risk of bias domains: sequence generation, concealment of allocation, blinding, incomplete outcome data, selective outcome reporting, and other sources of bias.
In addition, sequences generation, allocation concealment, incomplete outcome data, selective reporting and other bias were also inspected to assess the risk of bias [ 11].
