 Operations research is one of the most comprehensive research and analysis approaches to decision making. It is a product of World War II. Although its antecedents in scientific method, higher mathematics, and such tools as probability theory go back far beyond that period. There are extensive empirical evidence on its successful application in solving problems in American industries and across Europe. But not much has been heard of its usefulness in Nigeria. This research study is therefore a move toward this direction. The study is focused at findings out the relevance and the extent of application of Operations Research techniques in the decision-making process of managers in manufacturing firms across the Sough Eastern zone of Nigeria. To realize the objective of this study, the quasi-experimental design was employed, likewise, the descriptive research was used because it allows the researcher to look for fresh ideas and insight which helps to explain what was seen and how the identified variables inter-relate. Employing the simple random sampling technique, a sample size of 133 (determined through Saunders formula) out of the 1,482 workers in the six (6) manufacturing firms selected from Abia, Anambra and Imo States was used for this study. Primary data was collected through the administration of structured questionnaire validated by experts to ascertain the appropriateness of the items. Oral interviews were conducted as appropriate simple percentages were also used for data analyses. The Chi-square formular was to test the research hypothesis. The findings of the study showed that Basic statistics, inventory control techniques forecasting technique, Break-even analysis and decision analyses are the most frequently applied operations Research techniques in decision-making process of Nigerian managers in manufacturing firms. Only very few (23% or 31%) managers are familiar with the use of transportation technique, linear programming, computer simulation and PERT/CPM. It was further revealed that these techniques have been successfully applied by Nigerian managers in decision concerning the selection of building sites of plants, pricing, advertising and bidding procedures, development of quantity discount schedules, compatibility analysis for new products, and in locating points of distribution and warehousing. We strongly recommend the formation of Operations Research associations among Nigeria managers in public and private sectors and practitioners for there is none existing for now. This, we feel will encourage the floating of more operations Research journals, and regular mounting of seminars and workshops, thereby improving on the awareness level of the existence and relevance of Operations Research in Nigeria.
