• AI artificial intelligence
• the subject invention ⁇ e.g., in connection with selection) can employ various AI-based schemes for carrying out various aspects thereof. For example, a process for determining how often a medical package should record data can be facilitated via an automatic classifier system and process. Moreover, where the medical package is transported through several interim locations, the classifier can be employed to determine at which location he package should be activated for recording data.
• Such classification can employ a probabilistic and/or statistical- based analysis (e.g., factoring into the analysis utilities and costs) to prognose or infer an action that a user desires to be automatically performed.
• the AI component 1002 can also employ a risk assessment component 1004 that computes a degree-of-risk value for each of the medical packages 1006 (or articles of commerce) which can be used to determine how one of the packages 1006 should be handled, for example.
• a first medical package 1008 that is returned includes contents that pose a high degree of risk to a human handler
• the system at the distributor can read the data stored in the corresponding tag 1010 and determine not only the contents that were originally provided, but also the state in which the contents are after use. This also applies for handling at the research facility when shipping the used packages 1006 back to the distributor, and all handling that must be done while in-transit.
• the AI component 1002 can also employ a confidence component 1012 that computes based on some probabilistic/statistical-based analysis that the risk level assigned to a medical package is the correct level, for example.
• An inference component 1014 of the AI component 1002 infers some action that can be taken based on past actions and/or historical data. This inference can also be based on values computed by the risk assessment component 1004 and confidence component 1012. For example, if it is determined that a given medical package includes perishable drugs, it can be inferred that where a first transportation route will not get the drugs to the destination in time for use, a second route can be selected automatically. This would be based on past rerouting data associated with such a perishable drug, for example.
• a support vector machine is an example of a classifier that can be employed.
• the SVM operates by finding a hypersurface in the space of possible inputs, which hypersurface attempts to split the triggering criteria from the non- triggering events. Intuitively, this makes the classification correct for testing data that is near, but not identical to training data.
• Other directed and undirected model classification approaches include, e.g., na ⁇ ve Bayes, Bayesian networks, decision trees, neural networks, fuzzy logic models, and probabilistic classification models providing different patterns of independence can be employed. Classification as used herein also is inclusive of statistical regression that is utilized to develop models of priority.

• the classifier(s) can be used to automatically learn and perform a number of functions, including but not limited to determining according to a predetermined criteria how to route articles of commerce, how such articles should be handled, the level of risk assigned, and the number and types of alarms that can be assigned to a given package.

• the reconciliation system 310 can flag certain drugs, or other products as requiring special handling and transportation needs. For example, as described supra, one drug may be more perishable than another, requiring that cooling may be required (or that it be maintained above a certain temperature), and/or than it be shipped within certain time limit for optimum use. Another example can include the shipment of antidotes, bacteria, viruses, human organs, etc., all of which could require different logistics needs, hi any case, the logistics data for each package can also be uploaded to the corresponding tags (1010, 1016, and 1018) via the control and data acquisition system 308 to a reader/writer 1020.
• the reconciliation system 310 can include one or more capabilities of the control and data acquisition system 308 such that the reader/writer 1020 operates directly therefrom to communicate to and from the tags (1010, 1016, and 1018).
• the logistics data can include instructions written to the tag that describe how onboard program(s) will operate during at least one of out-processing of the package at the distributor, transport processing at any of several locations through which the package will travel, in-processing when arriving at the research facility, out-processing from the facility after the trial is over, transport handling at locations on the way back to the distributor, and in-processing at the distributor.
• the logistics data for the first package 1010 can include instructions that represent "no special handling is required”, “longest or cheapest delivery route is acceptable”, and “no environmental measurements required during transport”.
• Logistics data for the second package 1012 can include different requirements such as “special handling is required”, “quickest delivery route is required”, and “environmental measurements required during transport”. In any or all cases, this information can be made available during in-processing, out-processing, and during transport, when and wherever the package is energized and/or instructed to output the logistics data. [0082] hi the case of the second package 1012, it may be requested that environmental measurements should be made at only the second and fourth the stops of a five-stop route.
• the AI component 1002 can compute a confidence value via the confidence component 1012 which now indicates that viability of the product should shipment continue according to the original instructions. If the confidence value is low, the AI component 1002 can compute alternative measures that need to be taken. For example, the package can be intercepted at its current location and placed on hold.
• the AI component 1002 can compute and update instructions that are written to the tag 1010 to the effect environmental measurements need to be made more frequently.

• the measurements are automatically invoked when a signal has been received to the tag 1010 that triggers one or more instructions that enable the measurements to be made. If the measurements again confirm that the product is degrading, shipment instructions can be automatically changed to expedite shipment of the product.
• the inference component 1014 can determine from past data that a particular action was taken, and infer that in this case that the same action should be taken in this case.
• Such data can be made readily available to ship/receiving personnel via a handheld unit, for example, that reads the logistics data, and for tracking the package during shipment.
• a handheld unit for example, that reads the logistics data, and for tracking the package during shipment.

• the forward logistics data of the packages 1006 for shipment from the distributor to the research facility (or destination, in general) can be different than instructions for the return trip from the research facility to the distributor.
• logistics data related to only needles on the forward trip is might not be time sensitive or handling sensitive, yet the return trip could again, not be time sensitive, but require high-risk handling due to needle contact with contagious diseases.
• a drug that requires careful monitoring of environmental conditions and handling on the forward path might not require such care and handling on the return path.
• Alarms and other alert/notifications can also be employed based on the instruction and changes to the instructions written to the tag of the product, and changes in the risk levels associated with any given medical package and/or product contained therein. For example, a changing requirement during transport can call for different alerts to be generated at the destination or virtually any location of the package. An alert related to a medical product when first shipped can be changed for the same package when being shipped back to the distributor. Instructions for managing such alerts and notifications can be written to the tag at anytime and/or activated from an external system.
