Preparing Validated Mail Tray Labels abandoned, which became Ser. No.
07/963,013 filed Oct. 19, 1992, abandoned, which became Ser. No.
08/181,476 filed Dec. 29, 1993, U.S. patent application Ser. No. 641,985
filed Jan. 16, 1991 and entitled Automated Labeling System; and U.S.
patent application Ser. No. 07/900,397 filed Jun. 18,1992 and entitled
Just-In-Time Delivery System.
BACKGROUND OF THE INVENTION
Throughout the history of the mail delivery, there has been a gradual
evolution whereby the postal service encourages mailers to prepare their
mail in such a way as to reduce the effort required on the part of the
postal service for processing such mail. As an inducement to the mailer to
prepare the mail in such a way so as to bring about faster mail delivery,
the postal service offers a postage discount to mailers for such items as
presorted mail and printing of nine digit zip codes. Discounts are also
given when the mail is produced in a manner that allows automatic
processing with machines such as optical character recognition (OCR)
sorters and bar code readers and sorters.
Even with present mail processing techniques that have come into being as a
result of reduced postage rates for presorted mail, zip code mail and the
like, the postal service is still experiencing difficulties in meeting
targeted delivery times for the mail. The primary reason for such
difficulties is the increase in volume of mail that has taken place over
the decades.
Systems and methods have been conceived and described wherein the efforts
required by the postal service to process mail has been reduced. One of
the problems the postal service faced previously was that a significant
amount of mail presented to the postal service did not have the required
postage or did not meet the requirements of postal regulations. A scheme
for overcoming this problem was disclosed in U.S. Pat. No. 5,329,102
issued Jul. 12, 1994. In that patent application, a scheme is disclosed
whereby mail is processed in such a manner that the mail is sorted to
separate the local mail from the non local mail, the non local mail is
placed into trays in accordance with their zip codes and a label is
printed that identifies the mail in the tray for subsequent processing. As
a part of this scheme, the postal service is given a running account of
the mail being processed so that postage can be accurately determined and
the post office is able to process the mail further without having to
inspect the same to assure proper payment.
U.S. patent application Ser. No. 641,985, supra, discloses a system whereby
labels can be printed by a mailer for the trays and the sacks into which
mail is placed for a common carrier, particularly an air carrier. U.S.
Pat. No. 5,216,620 discloses a system and method whereby mail that is not
addressed locally is conveyed by a mailer to a common carrier. In so
doing, the mailer communicates to the local post office information
relative to the mail with regard to the number of trays of mail, their
weight, their destination and information that may allow the mailer to
receive a postal discount for the mail. Upon receipt of the information,
the post office would then determine the cost of air freight for the mail
which is looked upon by the common carrier as bulk freight.
Although the concepts described in these patent applications and patent
addressed areas where activities on the part of the mailer would benefit
the postal service, there are still many areas where the efficiency of
mail production can be increased.
In the prior production of mail, non local mail produced by a mailer so as
to obtain postal discounts was still sent to the local post office. This
procedure was addressed by U.S. Pat. No. 5,216,620 issued Jun. 1, 1993.
Although such a system functioned well, there was no correlation between
the destination of the mail being processed and the time of flight for
such destination. This was addressed by the concept disclosed in U.S.
patent application Ser. No. 07/900,397 supra. In that patent application,
a just-in-time scheme is disclosed whereby a mailer produces mail in such
a way that mail which is not addressed locally is conveyed to a common
carrier in sufficient time to be placed on the next transportation vehicle
without spending unnecessary time waiting to be loaded onto such
transportation vehicle. This just-in-time scheme was accomplished by
comparing the sequence in which mail runs were to be produced with the
transportation schedule of the common carrier and correlating the
production times of the mail runs with such transportation schedule.
Although use of the just-in-time scheme resulted in enhanced mail
production scheduling, there was a need still for monitoring of the
scheduled mail production and the time of arrival of the mail at the
common carrier to assure that the mail production schedule correlated to
the common carrier's dispatch schedule to assure that the just-in-time
scheduling was accurate.
SUMMARY OF THE INVENTION
A monitoring system has been devised wherein the actual production times of
mail are monitored and compared with the scheduled production times to
determine if there is a disparity between the two. The monitoring system
collects the data as mail production activity and dispatching are
occurring and displays the planned dispatch schedule. Regular updating of
the status of each distinction is possible by comparing the current time
to the scheduled dispatch time. If no trays to the destination remain, a
completed status is displayed. Any remaining trays of a scheduled dispatch
whose time has not elapsed are indicated as being in progress and on
schedule. Trays whose scheduled dispatch time has elapsed are identified
as being late, if the last possible dispatch time has passed or may have a
warning status issued if the current time is within a defined slack period
between the scheduled dispatch time and the last possible dispatch time.
These indications can quickly inform one as to the progress of production
runs. Overall run statistics can be presented, as well as performance
measures, such as expected mail delivery times based on actual dispatches
and assigned transportation routes. The last function of the monitoring
system is to prepare data for the entire production run for detailed
analysis by the mailers computer system so that future mail runs can be
improved in terms of correlating the production runs with the scheduled
dispatching.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 shows a mail production, dispatching system in which the instant
invention can be practiced.
FIG. 2 is a flow chart that represents the program for the monitoring
function of the invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to FIG. 1, a mail production and dispatching system is
shown generally at 10. In FIG. 1 connections for the transmission of data
are indicated by a single line and the physical conveyances of mail are
indicated by double lines. The mailer has a processor 12 that serves the
function of coordinating mail run production cycles with dispatching
schedules as will be described hereinafter. The processor 12 can be any of
a number of commercially available Compatible PC's with a 386 capability
or higher. The mail processor 12 is in communication with the postal
service 14 and is in connection with a main frame 16 which stores a
program such as a Finalist.RTM. mail schedule that contains names and
address lists of the recipients of mail. Each mail run that is designated
the by Finalist.RTM. mail schedule will be grouped in accordance with the
zip codes of the mail pieces. Ordinarily, such a mail list would arrange
the mail run in sequential numerical zip code order, but in accordance
with the scheme disclosed in U.S. patent application Ser. No. 07/900,397,
supra, the mail run will be organized in terms of their zip codes so that
they are able to arrive at a dispatch station just-in-time to be loaded
onto a common carriers vehicle. By mail run is meant a continuous mail
production with a large number of mail pieces grouped according to zip
codes. The sequencing of such mail runs is controlled by the processor 12
which reprograms the main frame 16 as required and in accordance with the
invention disclosed in Ser. No. 07/900,397 and the instant invention.
The main frame 16 is connected to a mail production facility 18 that is
capable of performing those tasks to produce mail runs. These tasks
include addressing the mail, inserting one or more inserts into an
envelope, weighing each mail piece, determining the postage for each mail
piece, placing the mail pieces into trays, printing a tray label for the
trays and conveying the trayed labels to a tray collection unit 20 where
they are placed into cages. All these functions are well known in the art
and will not be described hereinafter. See for example U.S. Pat. Nos.
5,142,482 and 5,216,620.
Upon completion of the mail runs, they will be placed upon a truck 22, or
other convenient vehicle, and transported to the common carrier 24. It
will be appreciated that more than one mail run can be placed on a truck
and the mail runs can have different zip codes depending upon the
dispatching schedule. For example one mail run could have the three digit
zip 302 for Georgia and another mail run 554 for Minnesota, but would
still comply with the common carrier dispatch schedule. The common carrier
24 can use any of a number of different types transportation vehicles,
such as trucks, ships, trains and the like, but this invention is
described with the use of an airplane 26. The airplane 26 delivers the
mail from the common carrier 24 to receiving station 28 of a postal
distribution center 30 where there will be a finer sorting of the mail for
distribution within the three digit zip and common carrier 24. A
monitoring process 32 is in communication with the mail processor 12.
Professor 32 also monitors the actual arrival time at common carrier 24
and determines of the time of a mail run arriving at common carrier 24 is
prior to the scheduled dispatch time.
In operation, the mail processor 12 will have loaded therein the dispatch
schedule of the common carrier 24. By dispatch schedule is meant the
arrival and departure times of transportation vehicles 26 to and from the
common carrier 24. This dispatch schedule may be provided either by the
postal service 14 or received by the mail processor 12 directly from the
common carrier 24. The mail processor 12 will communicate with the mailer
main frame 16 for the purpose of scheduling the mail runs to correlate
with the dispatch schedule of the common carrier 24. Reference can be had
to U.S. patent application Ser. No. 07/900,397, supra, for a description
as to just-in-time scheduling of mail runs.
The main frame will then control the production of mail runs at a mail
production facility 18. By a mail run is meant a set of mail pieces that
is to be delivered as a unit to the common carrier 24. This mail
production facility 18 includes a printer, inserter, scale, labeler and
other units necessary for the production of mail. Reference can be had to
U.S. Pat. No, 5,142,482 for details thereof. The mail is collected in
trays at the tray collection unit 20 and sent by truck to the common
carrier 24. It will be appreciated that if the mailer is in the vicinity
of a postal distribution center, the truck can take the mail directly to
such postal distribution center; however, in most instances it would be
necessary to deliver the mail to a postal distribution center by means of
an aircraft 26 and the like.
With reference to FIG. 2, the method by which the mail runs are monitored,
by the monitoring processor 32, will be described. The system 10 is
enabled 36 and mail pieces are produced 38 by the mail production unit 18.
As the operation begins, the dispatching schedule is displayed 40 on the
monitor of the monitoring processor 32. As a mail run progresses, the
question is asked, are there other trays to be booked 42, i.e., are
portions of mail runs to be produced. If the answer is no, then the
production run ends 44 and a post run analysis is made 50. But, if there
are other trays to be booked, the question is asked whether a disaster
recovery is required 46. A disaster recovery is necessary only in the
event of a system shutdown. If disaster recovery is required, then there
is an incremental update 48 and then the bookings are updated for the
remaining tray counts 52. More specifically, the schedule is re-arranged
so that those bookings that cannot meet the dispatch schedule are taken
out of sequence in favor of bookings that can meet the dispatch schedule.
If no disaster recovery is required 46, the bookings are directly received
and the remaining tray count updated 52. Thereafter, the statistics are
refreshed and the destination is closed out 54. Upon completion of this
step, the run statistics are updated 56 for each job and the question is
asked, does the remaining tray count equal 0. If yes, there is a return to
the production inquiry as to trays to be booked 42, but if no, the
question is asked is the current time less then the schedule dispatch time
60. If the answer is yes, then there is a return to the booking trays
engineering 42, but if the answer is no, the question is asked whether the
scheduled dispatch time is less than the current time and if the current
time is less than the last dispatch time before the mail run is late 62.
If yes, a behind schedule warning is given 64, but if no a late warning is
given 66. Thereafter, there is a return to the booked trays inquiry 42.
In the post run analysis 50, the monitoring processor 32 will review the
results of the mail production runs to determine how effectively the mail
production was scheduled. If it becomes evident that certain mail
production runs are being completed too late to conveniently meet the
common carrier dispatch schedules, the monitoring process will communicate
with the mailer processor 12 to bring about a revision in the mail
production schedule.
Thus, what has been shown and described is a method and apparatus that
achieves effective mail production to assure that mail is being produced
and sent to a common carrier in an expedient time so as to assure prompt
delivery to the postal service. More specifically, the method and
apparatus in the instant invention allow the monitoring of the scheduling
of production mail runs so that any inaccuracies can be corrected.
The above embodiments have been given by way of illustration only, and
other embodiments of the instant invention will be apparent to those
skilled in the art from consideration of the detailed description.
Accordingly, limitations on the instant invention are to be found only in
the claims.
