The organizational structure for project management is often chosen to mitigate risk in a weak capacity environment, but it may also reflect internal incentives that focus on speed of project processing and disbursement, and perceived stigmas in low implementation performance ratings. The result is often the use of PIUs—sometimes semi-permanently—even though regional studies have shown that they are suboptimal organizational arrangements and create problems of morale among government officials. While there are examples of good efforts during project design and implementation to focus on sustainable institutional capacity development and use of country systems, they are rare | Fuzzy Set Theory Applications in Production Management Research A Literature Survey Alfred L. Guiffrida Rakesh Nagi Department of Industrial Engineering 342 Bell Hall State University of New York at Buffalo Buffalo NY 14260 Abstract Fuzzy set theory has been used to model systems that are hard to define precisely. As a methodology fuzzy set theory incorporates imprecision and subjectivity into the model formulation and solution process. Fuzzy set theory represents an attractive tool to aid research in production management when the dynamics of the production environment limit the specification of model objectives constraints and the precise measurement of model parameters. This paper provides a survey of the application of fuzzy set theory in production management research. The literature review that we compiled consists of 73 journal articles and nine books. A classification scheme for fuzzy applications in production management research is defined. We also identify selected bibliographies on fuzzy sets and applications. Keywords Production Management Fuzzy Set Theory Fuzzy Mathematics. 1 Introduction Fuzzy set theory has been studied extensively over the past 30 years. Most of the early interest in fuzzy set theory pertained to representing uncertainty in human cognitive processes see for example Zadeh 1965 . Fuzzy set theory is now applied to problems in engineering business medical and related health sciences and the natural sciences. In an effort to gain a better understanding of the use of fuzzy set theory in production management research and to provide a basis for future research a literature review of fuzzy set theory in production management has been conducted. While similar survey efforts have been undertaken for other topical areas there is a need in production management for the same. Over the years there have been successful applications and implementations of fuzzy set theory in production management. Fuzzy set theory is being recognized as an .
