TAT has been widely applied in understanding technology adoption across various sectors, including artificial
intelligence. As AI tools increasingly support forecasting, decision-making, and automation, users’ acceptance
depends largely on their belief that such systems are beneficial and user-friendly (Unal & Uzun, 2021). However,
scholars note that while the model offers a strong foundation for analyzing technology adoption, it has
limitations. It focuses primarily on individual perceptions and does not sufficiently account for broader
influences such as organizational culture, social pressure, infrastructure readiness, or financial barriers (Kim &
Wang, 2021; Dutot et al., 2019). These omissions highlight the need for contextual considerations when applying
TAT in complex organizational settings.
Despite these limitations, TAT remains relevant in studies examining technological integration within supply
chains. Effective implementation of AI tools, including route optimization systems, depends on employees’
willingness to interact with and trust the technology (Liu et al., 2022). When users perceive AI-driven routing
platforms as beneficial, reliable, and easy to use, adoption rates rise, leading to improvements in operational
efficiency, reduced costs, and better decision-making.
In the context of this study, TAT provides a valuable lens for understanding how perceptions of AI-route
optimization influence its acceptance and subsequent impact on supply chain performance. The theory helps
explain how the independent variable (AI-route optimization) aligns with user behavior and ultimately influences
the dependent variable (supply chain performance) within large supermarkets.
Empirical Literature Review
Studies across different countries consistently show that AI-route optimization enhances supply chain
performance, though the extent varies by context and industry. In the USA, Vaka (2024) found that AI improved
delivery efficiency and customer satisfaction among e-commerce firms, though the study’s geographical and
sectoral focus limits its applicability to Kenyan supermarkets. Similarly, Khadem et al. (2023) reported that AI
improved efficiency and route decision-making in India’s manufacturing sector, but with a modest explanatory
power (R² = 0.052), indicating the need for further sector-specific research.
In Pakistan, Modgil et al. (2022) demonstrated that AI strengthens supply chain resilience through improved
visibility and last-mile delivery, although the study did not analyze specific AI tools such as route optimization.
Experimental findings by Hassouna et al. (2022) in Egypt showed that AI-based systems identified optimal
transportation routes that minimized cost and time (F = 1.38, ρ < 0.05). However, this research was limited to
the transport industry rather than retail.
Existing studies agree that AI contributes positively to logistics efficiency, but they reveal contextual,
methodological, and geographical gaps. Most research has focused on manufacturing, transport, or e-commerce
sectors outside Africa. The current study seeks to address these gaps by examining AI-Route Optimization and
supply chain performance in large supermarkets in Nairobi City County, Kenya.
RESEARCH METHODOLOGY
The study adopted a descriptive research design, which was appropriate for examining how AI-enabled route
optimization influenced supply chain performance among supermarkets in Nairobi City County. The target
population consisted of logistics, procurement, and operations personnel drawn from major supermarket chains
operating within the county. A census approach was used for supermarkets, while purposive sampling was
applied to select respondents directly involved in logistics decision-making.
Primary data were collected using structured questionnaires, which contained both closed-ended and Likert-scale
items aligned with the study variables. The instrument’s reliability was confirmed through Cronbach’s alpha,
where all constructs exceeded the acceptable threshold. Validity was ensured through expert review and piloting.
Data were analyzed using descriptive statistics, including means, frequencies, and standard deviations, to
summarize the characteristics of the variables. Inferential analysis, specifically regression analysis, was used to
determine the effect of AI-enabled route optimization on supply chain performance. Ethical considerations
