(International Journal of Supply and Operations Management, 2015) Nsikan Efiok John; John Joseph Etim; Tommy Uduak Ime
This study examines in ventory management practices in flour milling manufacturing firms and their effects on operational performance. Five flour manufacturing fi rms with aggregate staff population of 2569 constituted the unit of study . From the population space, 150 respondents were randomly selected. Structured questionnaire was the major instrument for the collection of relevant primary data while mean and standard deviation was used to analyze descripti ve data . Results showed that exception of the large manufacturing companies, most of the medium sized flour milling firms adopts different inventory management strategies from the scientific models. Their inventory management strategies and policies were r ather based on factors such as changing level of customer demand, prevailing industry practices, forecast estimates and guesses, and available productio n capacity. Findings also revealed sign ificant differences between effective management of inventory and optimal operating performance. For instance, while firms that scientific inventory management approaches reported efficiency in capacity utilization, increased service level, and reduced lead time, others with unscientific strategies had minimal utilizati on of material resources. There is need for flour manufacturing firms to implement scientific inventory management models to adequately handle material shortage s, product stock outs , and component pile up with consequent penalties.

(Journal of Transport and Supply Chain Management, 2022) John Nsikan; Eno A. Affiah; Ine Briggs; Nkechi Koko
Background: There has been considerable effort amongst commercially-oriented services firms towards achieving sustainable supplier selection. However, little is known about the specific sustainability factors employed by healthcare supply chain managers when selecting medical materials vendors in developing economies, and the impact that such selection approaches has on the buying firm’s performance. Objective: This study examines the sustainability factors mostly considered by Nigerian healthcare supply chain managers in their supplier selection processes. It further assesses the supply chain performance impact of the identified sustainable supplier selection factors. Methodology: The study adopted a quantitative survey approach to randomly collect and analyse primary data from a large sample of 116 logistics and supply chain executives in 58 healthcare organisations in Nigeria. The descriptive scores (mean and standard deviation) were summarised and used to estimate the relationship among variables. Results: Overall, the results suggest that economic sustainability towers above other sustainability factors for the selection of healthcare suppliers in the context of this study. In addition, economically sustainable supplier selection correlates strongly and positively with supply chain performance, while social sustainability supplier selection had moderate correlation with performance. Conclusion: Based on these findings, it is our conclusion that most healthcare supply chain managers in Nigeria attaches importance to economic sustainability factors in their supplier selection process than environmental and social sustainability factors.
