Determination of Production System Effectiveness Based on Sustainable Global Standards

Production system effectiveness determine to measure the sustainability of the established industries demands the development of a model for resolving global sustainable productivity challenges. The attributes (internal and external) of industrial failure were determined using questionnaire administration and oral interviews of industry experts in five (5) selected production companies in Nigeria: (Company A); (Company B); (Company C); (Company D) and (Company E). Production System Effectiveness (PSE) factors: Availability A, Performance P, and Quality Q were determined to arrive at manageable decision-making criteria under uncertainty, risk, or competition. Initial measures of PSE were based on the input internal factors (manpower, machine, material, energy, management, information/communication, money, and marketing), while sustainability decisions were determined using globally acceptable standards. The model was tested using data (weighted and normal) from the stated companies to determine their sustainability performances, while paired t-test statistic was used to test the levels of significant difference between weighted (WPSE) and normal (PSE) at 5%. The results indicated varying optimum decisions which were influenced by the nature/types of competition, risk, and standard of measure. The statistical result showed that there was a significant difference between the PSE and WPSE. These differences had little or no effect on optimum decision-making in all companies investigated.
