PDXpert PLM software manages parts lists, document identification and part numbering - and so much more! Parts list management using PLM software Parts list management requirements Although the definition of parts list management can vary, the basic idea is to allow designers to create a part record for an item that can be specified, qualified, purchased and used in production.
Document identifiers and part numbering systems A fundamental requirement for any development organization is to uniquely assign document and part numbers and to manage a central parts list. PDXpert PLM parts list management supports all organizational stakeholders: When creating a new part record, users are prompted for consistent item descriptions using "text templates" based on the part type.
A specifying designer can provide both budgetary and current unit costs for part list roll-ups. Each part can have its own supplier source parts list, which includes the ability to rank preferred usage.
For efficient data entry, we'll limit our delimiter choices to symbols on the numeric keypad. Part numbers are often used as the filename for importing bills of materials, exporting design packages and viewing file attachments.
Therefore, do not use:. The safest delimiter character is a hyphen: This is the hyphen minus sign on the numeric keypad , not the Unicode en dash — or em dash — characters. For consistency, if your number scheme includes a delimiter, all part numbers should share the same format.
For example, don't use for some parts, for others, and omit the dash entirely on yet others. Taking into account our rules, this very simple part number design has been successfully applied in a huge variety of industries, organization sizes and technical environments:. Conclusion : A part numbering system using 7 or fewer numeric characters is the easiest to manage for the majority of our users.
Five to seven numeric characters permit a universe of up to 10 million without leading zero, 9 million unique parts, far more than most companies will see over their entire lifespan. Recommendation : 6 numeric characters, no delimiter.
Start at and increment. Our short, numeric, non-significant part number provides the fastest data entry, with the fewest possible errors.
It's the most efficient solution for heavy users in purchasing, manufacturing, receiving, service and other places where employees constantly work with a wide variety of part numbers.
PLM software can easily generate the next part number in sequence, prevent conflicts with previously-issued part numbers, and find parts based on the number if you happen to know it and description and other attributes when you don't. If you're now wondering how part characteristics can be included in your part number, you're thinking of a "significant" "smart", "intelligent" part number scheme. Although significant numbering schemes are no longer considered good practice, we identify the risks and offer suggestions for avoiding some of the problems.
Experts strongly recommend the use of short, numeric-only, non-significant item numbers. We have not found any modern authority that recommends using significance in part numbering.
Here are some relevant comments from our PLM book list :. Another important point about item numbers is that they should be as short as possible. Part numbers are keyed, copied and used as verbal identifiers.
The shorter the numbers, the more accurate people can be. Obviously, the greater the number of digits in a part number, the greater chance of error. We also recommend that only numeric digits be used. The solution We have found that part numbers of 5 or 6 digits are the most effective. Garwood: Bills of Materials: Structured for Excellence , page 73 author's emphasis. Identification numbers are preferably short, not long. The characters that make up the number are preferably numeric, not alpha.
Any symbols to be used with the numeric characters are preferably limited to dashes. All tests point to numbers alone as being more easily identifiable with far less chance of error Tests have also shown that smaller numbers are easier to write and remember accurately. Hence, the ideal part number is all numeric with as few characters as possible. I prefer a non-significant number because there is a longer life and less error Typically, companies run out of numbers in certain categories of a significant number.
Also, a non-significant part number is more cost-effective to use than a significant part number. The most critical of these issues is that, over time, the significant numbering systems tend to break down. As time passes, variations arise which were not foreseen. One digit was set aside where two are now needed. Significant numbers thus tend to lose their significance.
