The present study aims to create a tool to investigate the learning of entrepreneurial skills via m-learning. An educational system to evaluate and enhance the learning of entrepreneurial skills and the creativity and innovations of the learners has to analyze the involved components. The effectiveness and importance of the components have to be determined to prioritize the components. In this research to create a tool, first a questionnaire that contained eighty-three questions was used to collect data. The statistical population included three hundred and thirty six BA students from the Faculty of Economics and Administrative Sciences at the University of Isfahan. Analyses were carried out by means of descriptive statistics and inferential statistical methods, including one-variable t-test and TOPSIS technique. This survey evaluates the effects of the m-learning on the learning components of the entrepreneurial skills and identifies the most effective components as well. The results revealed that there is a positive and significant relationship between the m-learning, the motivation, the degree of learner's participation, the variety of educational methods, the satisfaction and the increase in self confidence in learners of entrepreneurial skills. It also revealed that motivation, self-confidence and participation have the highest effect on learning of entrepreneurial skills.","PeriodicalId":410110,"journal":{"name":"2015 International Conference on Industrial Engineering and Operations Management (IEOM)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116462787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By mimicking the hormone controlled evolution process the algorithm works on a single candidate solution, going through initialization, iterative growth loop, and finally maturation loop. The method is a practical way to optimizing multi-objective problems with fuzzy conflicting goals and constraints. The approach is applied to the nurse scheduling problem. Equipped with the facility to incorporate the user's choices and wishes, the algorithm offers an interactive approach that can accommodate the decision maker's expert intuition and experience, which is otherwise impossible with other optimization algorithms. By using hormonal guidance and unique operators, the algorithm works on a single candidate solution, and efficiently evolves it to a near-optimal solution. Computational experiments show that the algorithm is competitive.","PeriodicalId":410110,"journal":{"name":"2015 International Conference on Industrial Engineering and Operations Management (IEOM)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117223398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methanol is a high value chemical that serves as an intermediate for producing common chemicals, use as a fuel additive, and as a method of energy storage. This work is about a design of a methanol plant with a production capacity of 5000 metric tonnes per day (MTPD). The design of the plant is also limited by the quality of methanol produced - Grade AA (99.85% methanol minimum, 0.1% water maximum), and to produce no more than 0.54 tonne CO2 emissions per tonne methanol produced. The heart of the design is to model the low pressure methanol technologies and to identify the advantages of different reactor types. In terms of economics, the growth in the demand for methanol has been seen to have a steady increase over the past few years. Based on the initial estimates for the plant costs, the capital required to build the plant is between 1-1.1 billion USD. Current market prices for a 5000 MTD plant would make a yearly gross income of approximately 50-100 million.","PeriodicalId":410110,"journal":{"name":"2015 International Conference on Industrial Engineering and Operations Management (IEOM)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128704672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The CFP is combinatorial in nature and due to difficulty faced in solving related mathematical programming problems; efforts have been made to use evolutionary approaches. Literature highlights that there are many advantages of converting batch type manufacturing system (BTMS) to cellular manufacturing system (CMS). In this paper, mathematical model has been proposed for groups to be emerged naturally. As mathematical model of CFP becomes NP- complete in nature, researchers advocate the use of meta-heuristics. Over the years, many different metaheuristic methods have been used to solve the CFP in group technology application. In the present paper, evolutionary population based method known as Particle Swarm Optimization (PSO) hybridized with assignment algorithm is used to solve cell formation problems. Due to these proposed changes, efficiencies of cell formed significantly increase in comparison to the results available in the literature. Proposed hybrid algorithm is applied to solve 30 different types of randomly generated and 10 standard CFPs, a large verity in terms of number of parts and number of machines required by these parts. For this algorithm, optimal values of parameters were also found with the use of Taguchi method. It is found that the proposed changes in algorithm and parameters obtained significantly impact the results in terms of efficiency values.","PeriodicalId":410110,"journal":{"name":"2015 International Conference on Industrial Engineering and Operations Management (IEOM)","volume":"1509 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127445338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To cultivate active learning, this was achieved with an embedded project in the engineering technology undergraduate course of Soil Mechanics and Foundations. The primary parameter examined was rainfall intensity. Students worked in groups to gather information, make careful judgment and identify links between rainfall intensity pattern over the years with localized landslide and flooding respectively. The students also conducted interviews with locals of the selected site for firsthand information and eye witness accounts. It was found that these geo-disasters were partially caused by a change in the rainfall pattern over the years, while other anthropogenic activities have also contributed to the recurring and seemingly worsening disasters. In conclusion, the project has effectively killed two birds with one stone: (1) identified the severity of climate change impact on geo-disaster occurrence in certain localities, and (2) engaged students (future engineers and technologists) in a scientific research exercise pertaining to a current issue very relevant to the course. From the education perspective, the undertaking has enabled students to hone their investigative skills in addressing a technical problem, encouraging them to adhere by their social responsibilities while performing their professional tasks.","PeriodicalId":410110,"journal":{"name":"2015 International Conference on Industrial Engineering and Operations Management (IEOM)","volume":"202 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130175568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, the available measured solar and wind data of the cities (Chabahar, Kish and Salafchegan) including horizontal global solar radiation, and wind speed data at 10 m elevation were analyzed. Also, key solar parameters like monthly mean global, beam and diffuse solar radiation as well as clearness index were investigated too. For analyzing the wind potentials, Weibull Distribution Function (WDF) was performed at different heights. The annual wind speeds and wind powers of locations at 20, 30 and 40 m heights were calculated. The study results clearly demonstrate that wind as a renewable energy source can supply a portion of the energy demands for Kish and Salafchegan with yearly wind powers of 111.28 W/m2 and 114.34 W/m2, respectively ranked in class 2 which are considered marginal for wind power development. It was also illustrated that all three locations had great potentials for utilizing different solar energy applications. In addition, the monthly, seasonal, seim-yearly and yearly optimum tilt angles of south facing solar collectors and panels were determined. For all locations adjusting the tilt angle twice a year or in other words, the semi-yearly tilt adjustment for two periods of warm and cold were suggested.","PeriodicalId":410110,"journal":{"name":"2015 International Conference on Industrial Engineering and Operations Management (IEOM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130980857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
