Information for designing queuing systems

[the_wind]

I have decided to work on queuing systems...i want to implement it in our school, coz its very especially during enrollment...

can you give me guyz a useful info, papers, schematics or overview regarding this topic of mine...

tnx and god bless in advance....

project with isd4004 and microcontroller pic

Have done several projects of this sort in the past for hospitals and clinic. The first way is also the easiest way is to use 3" or 4" 7-segments. I have put full schematics and source code in my web site (under the PIC section)

The second way is to use some sort of LED matrix panel. In the past, I have used 192*64 tri-color LED bar for this job. Wit a 16F877 PIC mcu and a voice recorder chip isd4004, it is possible to finish queue number calling in recorded tru human voice.

The third way is to use LCD TV, using a PC with Windows software.

I particularly wanted to do the PRIORITY NUMBER SYSTEMS.....Those mostly applied in the banks.....

Help me plzzzzzzz...............

how to make a queuing system

PRIORITY NUMBER SYSTEMS

What do you mean by that? Is it some sort of priority banking, for those who has a million at the bank, that guy/lady won't need to queue any more!

By the way, have been doing first come first serve system, or freehand system that the caller would have complete freedom to call anyone in the queue. It depends what kind of logic to use.

swedish queuing system

I particularly mean PRIORITY NUMBER SYSTEM that are being implemented in banks to handle costumers in order. Its like a number given to each costumers so that whenever the number they have at hand is being called, then it is their chance to be entertained.

The algorithm is just like that...I would like to implement it in our school, so that the enrollment and business transaction flow would be so easy to manage and handle....

priority number queuing system

So, I think there are more than one service counters in this case. What about queue ticket dispensing? Is it going to be a single queue ticket printer? If yes, you may consider using a PC controlling the Q number and doing the ticket printing management. That PC is connected to keypads via some sort of RS485 network, or LAN network. Say, you have 10 counters with 10 keypads. Each keypad is showing the current customers in the Q. The service provider at each counter could make a free-hand keypress for a 3-digit Q number (say 123). To avoid mistake, each keypad is equipped with a LCD display to show the current number on call. An ENTER key to confirm calling, and then that Q number would be deducted from the control controlling software....

Re: QUEUING SYSTEM

Can i have some articles, papers or websites that i can visit regarding dis matter..?

Thanks and God bless...

Re: QUEUING SYSTEM

Type automatic queuing system or electronic queuing system (EQS) in Yahoo or Google will give you some hints. EQS is a commercial product.

Re: QUEUING SYSTEM

Thanks anyways...can you help me in designing the system? What is my first step in this research project?

Re: QUEUING SYSTEM

First define the requirement such as:

How many calling counters?
How many queue?
Is the calling preference a first come first serve basis?
How big is the display for the public required? What format? Is it to be a simple 7-segment, or dot-matrix LED display, or color LCD TV?
Should there be any true human voice annoucement for calling? Or simple Ding Dong alert?
How many systems to be built for this system?
Should we handle a moulding enclosure to the customer for low-volume production, or should we use off-the-shelf item like PS2 keypad for calling counters, PC keyboard, or we make a custom-made enclosure?
.....

Many questions can be asked for this sort of project.

Re: QUEUING SYSTEM

By the way, we're already designing the EQS and were hoping that it'll work the way we want. But the research has many parts, i really lack published materials for the documentation and review of related literature. And also if we have those then we can compare with the existing.

My instructor told me that my paper lacks supporting details and facts. The papers that i'm searching is about Computer-based queueing systems, Microcontroller-based queueing system and hardwired queueing system. Since I am on the research of Hardwired queueing system, i still need to compare it to the two i have abovementioned.

Hope somebody can help me......

Thank You.....Hope i can help you by donating some of my available points....

Re: QUEUING SYSTEM

What is "hardwired queueing system"?

Re: QUEUING SYSTEM

Its like building the system with different components of IC...unlike of microcontroller wherein the system's behavior is being programmed.

Re: QUEUING SYSTEM

hi
i am trying to make a queuing system but i am facing a problem in the distance of the switches and the displays as they will be far away from the mcu, so, the signal will be distorted. have anyone any idea how to solve this problem?
