Research ArticleOpen accessAll words, across the recordSolving the Periodic Maintenance Scheduling Problem via Genetic Algorithm to Balance Workforce Levels and Maintenance CostMohamed Ali Abdel-Fattah MansourProblem statement: In this article we address the multi-objective Periodic Maintenance Scheduling Problem (PMSP) of scheduling a set of cyclic maintenance operations for a given set of machines through a specified planning period to minimize the total variance of workforce levels measured in man-hours and maintenance costs with equal weights. Approach: The article proposed a mixed integer non-linear math programming … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 12 Jul 2011 · 8,322 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordPolitical Instability and Firm Performance: A Microeconomic Evidence from Ivory CoastErnest Ouédraogo, Ibrahim Ouédraogo, Emmanuel LompoIn this paper, we investigate how political instability affects firms’ performance in Ivory Coast. Using data from the World Bank's 2016 survey of 361 firms in Ivory Coast, we perform a robust endogenous treatment model to assess causal the impact of political instability on firm productivity. The results indicate that political instability is statistically significant and negatively associated with firm … …American Journal of Economics and Business Administration, Vol. 12, Issue 1 · 23 Oct 2020 · 9,184 accessesView PDFCite
