Efficiency in Central Public Sector Enterprises in Kerala

For the analysis of productivity, capacity utilisation and profitability the data relating to the manufacturing central public sector enterprises in Kerala have been collected from the published annual reports of the companies, public enterprises surveys of Bureau of Public Enterprises (BPE), Economic Review of State Planning Board (SPB) and statistical review of central government enterprises by Centre for Monitoring Indian Economy (CMIE). Primary data have been collected by conducting personal interview with the high and middle level executives.

Study on Fuzzy Ordered FuzzyTopological Spaces

In this study we combine the notions of fuzzy order and fuzzy topology of Chang and define fuzzy ordered fuzzy topological space. Its various properties are analysed. Product, quotient, union and intersection of fuzzy orders are introduced. Besides, fuzzy order preserving maps and various fuzzy completeness are investigated. Finally an attempt is made to study the notion of generalized fuzzy ordered fuzzy topological space by considering fuzzy order defined on a fuzzy subset.
