Research Methods
This article uses a combination of quantitative
research and qualitative research.
Combined Analysis Method of Quantitative
and Qualitative Research The quantitative
analysis method is based on empirical data
and existing numerical results, so it has high validity
and reliability. Qualitative data are a detailed
description of events, characters, behaviors, previous
experiences, beliefs, and past cases. In many
cases, both quantitative and qualitative methods
can be used in combination.10,11
CombinedAnalysisMethodofQuestionnaire
SurveyandLiteratureResearchBy disseminating
questions of specific groups of people, setting
targeted questions, and setting mental dimensions,
we can understand the audience situations of questions
about the industry and their real needs. The literature
research methodology is to provide useful
information and documentation for this research by
researching literature, in order to improve field
research and to obtain evidence.12,13
Management Theory of Apparel Brand

Specialty Retailer of Private Label Apparel
(SPA) Mode SPA is a vertical and vertical sales
model that integrates the development of original
products to design, production, and sales. Figure 2
shows the in-store picture of a fast-fashion store.14
Long Tail Theory The long tail theory is a new
theory that is often used in the development of
apparel companies. This view demonstrates that
with the rapid development of clothing products,
the focus on corporate management shifts from

tail production, more variability, and the production
of smaller batches.15
ALOHA Algorithm Mode
The ALOHA algorithm is the most basic random
tag anticollision algorithm. Accept tag drive
function: once the marker has entered a student's
application level and receives a query command
from the reader, it will send its details to the
reader. Figure 3 shows how this algorithm works.
In the ALOHA algorithm, the data packet p
sends k labels (k ¼ 0,1,2,...) at a certain moment,
and the average exchanged data packet volume
P can be expressed as
