Choosing a Warehouse Management System (WMS)

Overview: The objective of the warehouse is to maximize the use

of warehouse resources while exceeding the customer’s requirement.

Many warehouse do not have WMS support yet still achieve very high inventory accuracy and very low outbound error. They add checkers, pickers and the proper paperwork to account for the warehouse activity.

Choosing WMS is to accomplish the same customer objectives. Balance of people time versus computer time.




WMS increased accuracy and minimize uncertainty.

Warehouse system range in complexity from very simple stock locator systems to systems that truly optimize space, equipment and labor.

All system use some form of data entry automation to minimize errors and all system track inventory by individual stock location on a real time basis to eliminate any and all uncertainty in the warehouse inventory and its location..



Primary benefits to an organization looking for a WMS is to increased accuracy and minimize uncertainty.

High accuracy and no uncertainty allow one to: (benefits) Stop Customer Complaints Stop Physical Inventories Stop excessive returns Stop Stoking Errors Stop Picking Errors Stop Poor Space Utilization Stop Inventory Accuracy Errors Stop Excessive Seek and Search Times Stop Poor Productivity Stop Excessive Expediting


Tools- Accuracy Tools Accuracy of data is only as good as the tool used to

capture and record the data. Be it recording the part number and quantity upon

receipt, the methods used to verify and record the receipt are crucial to maintaining the accuracy.

The tools used to provide data capture accuracy are group under industry heading Auto ID.

Auto ID represents many technologies that strive to provide fast and accurate data capture. Radio Frequency Identification (RFID) Optical Character Recognition (OCR) Magnetic Stripe Voice Recognition Bar Coding


Before choosing a tool, one’s environment and specific requirements need to be considered. Contact vs non contact- do you need to be able to touch the

products or label. Line of Sight- Do you need to see the product or label capture

data? Is there sufficient light to adequate see the data to be captured.

Environment – Is the climate a decision factor or is the environment filled with harsh chemicals

Data Density – How much data you need to capture, and how big is the area to read the data?

Cost- What is the desired cost for this tool First Read Rates- How critical is it that very first read is good.

OVERVIEW OF RFID (Radio Frequency Identification)

Technology that is most commonly found in retails apparel stores to sound alarm in case of theft.

RFID contain unique information that identifies whatever they are attached to.

Share information wirelessly with computer databases and networks so items can be tracked efficiently.

What we may not know is how far the technology has come and what is being developed right now that could help our warehouse or distribution centre.

What is RFID?

RFID is best described as a wireless memory chip or smart tag, that is attached to both the products and transport packaging.


DECISION MAKING TO USE RFID (Radio Frequency Identification) To help decide if RFID would be beneficial to, consider if any of the

following statement apply to our business. We deal with high value goods that need to be protected. A bar code cannot physically survive our processes. Areas of our facilities need to be protected from unauthorized

access. We need more unique information on each item than a bar code

can contain. We are highly automated and need to minimize human

intervention. We could benefit by knowing where products are at all times in

the supply chain in real time. IF ANY OF THE ABOVE APPLY TO OUR BUSINESS, RFID

SHOULD BE GIVEN SERIOUS CONSIDERATION. JLB20903-C6 Warehouse Information

HOW RFID WORKS?

RFID offers higher data storage capacity, higher identification speed and greater immediacy and accuracy of data collection.

RFID controls the wireless reading and writing information stored on an RFID tag by generating the radio frequency field around the antenna.

The RF field gives the tag power (if passive tag) and a way to transfer data from the tag to the reader.

The tag modulates the reader’s RF field and reader can detect this

Likewise, the reader turns the RF field on and off in the light sequence in order to write the tag.


COMPONENTS OF RFID SYSTEM

A basic RFID system consists of three (3) components.A programmable RFID tag for storing data.An antenna to facilitate the reading and

writing of data into the tag.An Antenna that encodes/decodes the data in

the tag’s integrated circuitry.

THE RFID TAG

Figure: Construction of a RFID tag (Thermal Transfer Paper can also be PET substrate)

The programmable RFID tag is an integrated circuit (IC) embedded in a thin film medium. Information stored in the tag is transmitted via radio frequencies to an RF reader. The performance characteristics of the RFID tag will be determined by factors such as the type of IC used, the read/write capability, the radio frequency and the read range.


Most common Auto ID technology

Put in the simplest terms a bar code functions much like Morse code. Whereas the morse code is the use of dots and dashed to represents alphabetic and numeric characters, the BAR CODE using parallel dark bar to represents alphabetic and numeric characters.

Barcode scan by the barcode reader, scanners and interpretive software available on devices including desktop printers and smart phones.

BAR CODING

DIFFERENCES BETWEEN RFID AND BARCODES.

RFID and Barcode are both identification technologies that allow identification data to be stored and read back with a reader.

While barcode been around for ages, the ideas using RFID in application such as supply chain management is a new concept. RFID has been coined as the “wireless” or “radio” barcode.

Next slide shows the table of comparison on differences between barcode and RFID

Reading Distance

limited distance. Required line of sight requirement.

Enables reading from greater distance and in harsh environment. This is due to no line on sight requirements.

IMPLEMENTING A WMS In general warehouse performs 4 basic functions:

1- Received products Purchased items Third part finish goods Customer returns

2- Store products Quality inspection Putaway Location and lot control

3- Pick Products Raw materials picking WIP pickings Finished goods picking

4- Ship products Internal customer shipments External shipments

IMPLEMENTING A WMS

Implementation of WMS will accomplished the below areas:Order entry – quickly accurate order entry by

using WMSOrder Scheduling- with WMS we able to plan

the warehouse activities, allocate labor, work load, optimize labor and equipment assignment.

Receiving Functionality – efficient, accurate receiving. Real time validation can be done.

IMPLEMENTING A WMSStorage functionality

With WMS, we can maximize space utilization, maximize picking efficiency, minimize labor.

Real time update inventory and products tracebility.
