Therefore, conventional modeling of these systems using deterministic parameters is questionable. Fuzzy simulation enables modeling uncertainties in such systems. The objective of this study is to model and improve concurrently the performance of integrated information, business, and production process of a manufacturing system using fuzzy simulation. Here, performance is defined as customer satisfaction. The superiority of the fuzzy simulation approach over conventional models used in prior studies is discussed. The integrated fuzzy approach in this study enables evaluating customer lead times in six dimensions with uncertainties considerations. Major effects of business process reengineering and information technology are evaluated before the actual implementation. The comparison results indicate that the fuzzy model is closer to the actual system. This is the first study that presents an integrated fuzzy model for improvement of customer satisfaction in integrated information, business, and production processes with ambiguity.<\/jats:p>","DOI":"10.1177\/1063293x12461641","type":"journal-article","created":{"date-parts":[[2012,12,17]],"date-time":"2012-12-17T02:32:53Z","timestamp":1355711573000},"page":"287-299","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["A unique fuzzy simulation approach for concurrent improvement of customer satisfaction in integrated information and production processes with ambiguity"],"prefix":"10.1177","volume":"20","author":[{"given":"Ali","family":"Azadeh","sequence":"first","affiliation":[{"name":"Department of Industrial Engineering, College of Engineering, University of Tehran, Tehran, Iran"},{"name":"Department of Engineering Optimization Research and Center of Excellence for Intelligent Based Experimental Mechanics, College of Engineering, University of Tehran, Tehran, Iran"}]},{"given":"Zeinab","family":"Raoofi","sequence":"additional","affiliation":[{"name":"Department of Industrial Engineering, College of Engineering, University of Tehran, Tehran, Iran"},{"name":"Department of Engineering Optimization Research and Center of Excellence for Intelligent Based Experimental Mechanics, College of Engineering, University of Tehran, Tehran, Iran"}]},{"given":"Moeed","family":"Haghnevis","sequence":"additional","affiliation":[{"name":"School of Computing, Informatics and Decision Systems Engineering, Arizona State University, Tempe, AZ, USA"}]},{"given":"Mahboubeh","family":"Madadi","sequence":"additional","affiliation":[{"name":"Department of Industrial Engineering, College of Engineering, University of Tehran, Tehran, Iran"}]}],"member":"179","published-online":{"date-parts":[[2012,12,16]]},"reference":[{"key":"bibr1-1063293X12461641","volume-title":"The IT Manager\u2019s Survival Guide","author":"Alders R","year":"2002"},{"key":"bibr2-1063293X12461641","doi-asserted-by":"publisher","DOI":"10.1016\/S0305-0483(99)00072-9"},{"key":"bibr3-1063293X12461641","volume-title":"Proceedings of 5th international conference on analysis of manufacturing systems\u2014production management","author":"Azadeh A","year":"2005"},{"key":"bibr4-1063293X12461641","volume-title":"Proceedings of 5th international conference on analysis of manufacturing systems\u2014production management","author":"Azadeh A","year":"2005"},{"key":"bibr5-1063293X12461641","doi-asserted-by":"publisher","DOI":"10.1002\/asi.20712"},{"key":"bibr6-1063293X12461641","volume-title":"42nd Annual Simulation Symposium (ANSS\u201909)","author":"Azadeh A","year":"2009"},{"key":"bibr7-1063293X12461641","doi-asserted-by":"publisher","DOI":"10.1007\/b100371"},{"key":"bibr8-1063293X12461641","doi-asserted-by":"publisher","DOI":"10.1016\/S0165-0114(97)00023-7"},{"key":"bibr9-1063293X12461641","doi-asserted-by":"publisher","DOI":"10.1109\/HICSS.2004.1265057"},{"issue":"3","key":"bibr10-1063293X12461641","doi-asserted-by":"crossref","first-page":"219","DOI":"10.1016\/S0268-4012(99)00015-8","volume":"19","author":"Giaglis GM","year":"1999","journal-title":"Information Management"},{"key":"bibr11-1063293X12461641","doi-asserted-by":"publisher","DOI":"10.1016\/S0360-8352(99)00054-6"},{"key":"bibr12-1063293X12461641","doi-asserted-by":"publisher","DOI":"10.1016\/j.simpat.2005.01.006"},{"key":"bibr13-1063293X12461641","unstructured":"Haghnevis M (2003) Design of an integrated information and production system via computer simulation.
