Easy
Which part numbering method assigns numbers in increasing order without embedding any product attributes?
Intelligent
Sequential
Mnemonic
Hierarchical
Sequential numbering uses simple incrementing numbers without encoding any attributes. It is distinct from intelligent or hierarchical schemes that embed characteristics into the code. This makes it easy to implement but provides no attribute information.
Which part numbering approach uses meaningful letters or abbreviations to convey product attributes directly in the code?
Mnemonic
Random
Check-digit
Sequential
Mnemonic part numbers use letters or abbreviations that hint at product attributes, such as material or size. This contrasts with sequential codes, which carry no meaning, and random codes, which are arbitrary. Check digits are used for error detection, not for conveying attributes.
What is a primary advantage of using a hierarchical part numbering system?
It always yields the shortest codes
It prevents any encoding of attributes
It groups parts based on defined category levels
It uses random allocation for security
Hierarchical systems structure codes into segments that reflect category levels, making it easy to see parent-child relationships. They do embed attributes, unlike random systems, and are not necessarily the shortest format. This grouping aids in organization and retrieval.
Intelligent part numbering is especially useful in which industry due to its need for detailed attribute traceability?
Retail fashion
Electronics manufacturing
Banking
Hospitality services
Electronics manufacturing often embeds attributes like voltage or tolerance directly into the part number for quick identification. Retail fashion and hospitality rarely need such technical detail in codes, and banking uses account-based numbering rather than intelligent part coding.
What is the primary purpose of a standardized part numbering system?
To uniquely identify and categorize components
To reduce inventory levels automatically
To encrypt pricing information
To increase the physical size of labels
A standardized part numbering system ensures each component is uniquely identified and categorized for efficient tracking and procurement. It does not inherently encrypt prices or change inventory levels, and has no relation to the physical size of labels.
Medium
In the part number 'MTR-150-3PH-400V', what does '3PH' represent?
Three-phase power configuration
Rotational speed
Single-phase power
Horsepower rating
'3PH' in the code indicates a three-phase electrical configuration. It differentiates from single-phase systems and is not a horsepower or speed descriptor. Embedding this attribute aids quick identification of motor type.
In a code like 'ABC1234', if 'ABC' represents the product category, what does '1234' most likely represent?
The manufacturing date
The supplier location
A sequential identifier within the category
A random security key
After a category prefix, the numeric portion often serves as a sequential identifier for individual parts in that category. Dates and supplier codes are typically separate segments in more complex intelligent systems. Random keys are not common in category-based codes.
Which guideline helps avoid confusion when designing alphanumeric part numbers?
Include special characters for clarity
Exclude letters 'I' and 'O' to prevent misreading as digits
Use only uppercase vowels
Mix lowercase and uppercase freely
Excluding 'I' and 'O' reduces confusion with the digits '1' and '0', enhancing readability. Using only vowels, random case mixes, or special characters can introduce ambiguity or errors in manual entry.
Which strategy best supports scalability in a part numbering scheme?
Use handwritten numbers for flexibility
Reserve numerical ranges for future categories
Limit codes to four total characters
Embed manufacturing date in every code
Reserving ranges for future use prevents code exhaustion and simplifies future expansion. Four-character limits and handwritten numbers restrict growth and accuracy, and embedding dates in every code increases complexity rather than scalability.
What is a key practice to ensure uniqueness in a distributed part numbering environment?
Allow each site to reuse old numbers
Assign numbers based only on local batch sizes
Use the same raw sequence at every location
Implement a centralized registry for assigned ranges
A centralized registry prevents overlapping assignments by tracking ranges allocated to each location. Reusing numbers or duplicating sequences at different sites causes conflicts, and local batch-based numbering lacks global uniqueness.
Which approach improves maintainability of a numbering system over time?
Embed every attribute change into the part code
Change codes annually to reflect current trends
Use variable-length codes with no fixed structure
Store detailed attributes in a separate database, keeping codes simple
Decoupling data storage from the part code lets the numbering scheme remain stable while allowing attribute updates in a database. Embedding every change in the code or using variable lengths increases complexity and reduces maintainability.
How many unique part numbers can a purely numeric, 12-digit system generate?
1,000,000,000
12,000
1,000,000
1,000,000,000,000
A 12-digit numeric system offers 10^12 unique combinations, which equals one trillion possibilities. Six digits would yield a million, and nine digits a billion, so the correct scale for 12 digits is one trillion.
What is a common drawback of intelligent (attribute-based) part numbering schemes?
They cannot represent more than one attribute
They become inflexible when attributes change over time
They always require the shortest possible code
They eliminate the need for a database entirely
Intelligent schemes may need redesign if product attributes evolve, making them less flexible. They can represent multiple attributes and often require external data management as well. They also do not guarantee shorter codes.
Which practice enhances human readability in part codes?
Combine all segments into one unbroken string
Use only lowercase letters without spacing
Embed special symbols in the middle of codes
Use fixed-length fields with visible separators
Separators or fixed-length fields make it easier to parse and read codes quickly. Unbroken strings, uniform lowercase, or arbitrary symbols tend to hinder readability and increase chances of data-entry errors.
Hard
When rolling out a global part numbering scheme, which element most reliably prevents cross-site conflicts?
Assign a unique location prefix to each site
Rely on date stamps alone for uniqueness
Use a shared three-digit local code at all sites
Allow each facility to reuse numbers quarterly
A unique location prefix ensures no two sites generate overlapping codes. Shared codes or reused numbers lead to conflicts, and date stamps alone cannot guarantee uniqueness without additional qualifiers.
A 6-digit scheme has run out of codes. What is the most maintainable way to expand capacity?
Restart the sequence from zero annually
Embed the year into the existing 6 digits
Switch to purely alphabetical six-digit codes
Add two extra digits in a new fixed position
Adding fixed extra digits expands capacity while keeping the existing structure intact. Switching entirely to letters or restarting sequences introduces confusion and conflicts, and embedding the year reduces numeric space without adding more unique combinations.
How many unique combinations can a code with 4 uppercase letters followed by 4 digits generate?
10^8
26^4 × 10^4
26^8 × 10
4^26 × 4^10
Each of the 4 letters has 26 possibilities and each of the 4 digits has 10 possibilities, giving 26^4 × 10^4 total combinations. Other formulas misapply exponents or invert the count of options.
Which process most effectively prevents part number duplication across multiple teams?
Use random numbers with no coordination
Allow teams to self-assign codes freely
Grant each team a small shared block of codes
Enforce a centralized approval workflow for new codes
A centralized approval workflow ensures each new code is checked against existing numbers before assignment, preventing duplicates. Self-assignment or uncoordinated random codes runs a high risk of overlap, and small shared blocks are easily exhausted.
What is the primary function of a check digit in a part numbering system?
Detect transcription or entry errors in the code
Reduce the overall length of the code
Indicate the manufacturing date
Encrypt the part number for security
A check digit is calculated from the other characters to reveal mistakes in typing or scanning. It is not used to encrypt data, mark dates, or shorten the code, but solely to improve data integrity.
