ABSTRACT
This study examined the connection between supply network design decisions and service quality of paint manufacturing firms in Rivers State. The study adopted a correlational research design and collected primary data via cross-sectional survey, using structured questionnaire. The Pearson Product Moment correlation served as the test statistic, relying on the statistical package for social sciences (SPSS) version 23.0. The study found that supply network design decisions (facility location, transportation mode and vehicle routing) have strong, positive and statistically significant association with service quality, with transportation mode and service quality having the strongest link. The study concluded that supply network design decisions inform service quality of paint manufacturing firms in Rivers State, and that service quality of paint manufacturing firms in Rivers State depends on supply network design decisions. The study thus recommends that paint manufacturing firms in Rivers State that seek improved service quality should pay attention to supply network design decisions such as mode of transportation, facility location, and vehicle routing.
