A project is always performed in an environment influenced by resource and environment factors such as equipment, weather, labor skill, materials delivery, management quality and so on. Since these factors affect various activities on the same path in an activity network, activity durations tend to vary together. The variation of these durations affect the path duration and/or the project duration. This paper introduces a new method that incorporates these factors in a fuzzy activity network and provides factor sensitivity information to support efficient project schedule management. This method uses a triangular fuzzy number for the activity duration, and uses the spread of the triangular fuzzy number for the variation in the estimation of the activity duration. Based on the qualitative estimations of the sensitivity of each activity to each factor, the variation in activity duration is distributed to several factor variations (f-variation). Each f-variation is then broken down into more variations based on factor conditions (c-variations), with each c-variation corresponding to a factor condition such as better-than-expected, expected, or worse-than-expected. The effects of resource and environment factors are captured using c-variations under the same factor conditions to compute path and project durations. The proposed method makes it possible to improve the estimation of the path and project durations. The sensitivity of paths to factors can be searched and effectively used to improve project schedule management. Finally, an example is demonstrated, and the results are compared with other methods.

Establishing an effective and secure operating and logistics base under austere conditions, either at home or abroad, regardless of whether the origin of the crisis is military or strictly humanitarian in nature, is a complex mission. Unfortunately, the doctrine supporting the life-cycle management of base camp facilities is poorly codified and usually unstructured due to the disparate nature of the governmental organizations tasked with accomplishing these missions. In order to overcome this problem, the department of systemsengineering at the United States Military Academy (USMA) at West Point has developed functional and non-functional requirements for, and has partially implemented a commercial-offthe- shelf (COTS) knowledge management (KM) system that facilitates the sharing of this type of specialized information for military and civilian members of the "Base Camp Community of Practice (CoP)".
The primary purpose of this study was to identify the desired characteristics of an undergraduate Industrial Engineer as an entry-level employee, and to determine the emerging topic areas that should be incorporated i...

Reserve price auctions are one of hot research issues in traditional auction theory. Here we study the starting price in an online auction, the counterpart of the public reserve price in a traditional auction. By considering three features of eBay-like online auctions： stochastic entry of bidders （subject to Poisson process）, insertion fee proportional to the starting price, and time discount, we have analyzed the properties of extremum points of the starting price for maximizing the seller＇s expected revenue, and found that, under certain conditions, the optimal starting price should be at the lowest Mlowable level, which is contrary to the results from the classic auction theory and finds its optimality in reality. We have also developed a general extended model of multistage auctions and carried out analysis on its properties. At last, some directions for further research are also put forward.
In this paper the authors propose a structural method for a genetic algorithm (GA) for the optimization problem of cable routing in which cables have to be laid optimally. When there are no limits on the layout routes...

The effort to incorporate ethics concepts into engineering curriculum in higher education has increased over the last several years. The engineering ABET Criteria includes understanding professional and ethical responsibilities. There has been increased funding from the National Science Foundation to develop ethics courses, incorporate ethics modules within existing engineering courses and develop discipline-specific ethics cases. In a search of the ethics literature and the ASEE engineering Case program, there were few industrial engineering or engineeringmanagement related cases found that could be incorporated as ethics modules across the curriculum. This paper will provide an approach to incorporate ethics cases as modules across an industrial engineering and engineeringmanagement curriculum and related courses. This paper describes the proposed project objectives, a methodology for developing engineering ethics modules and engineering conceptbased cases, as well a description of the project deliverables, the approach to disseminate the case modules, and the project evaluation and assessment approach to ensure that the project objectives are successfully met.
The engineeringmanagementprogram of the University of North Carolina at Charlotte (UNCC) is a master's level program founded in Fall 2000, offering courses together with the College of Business Administration an...

The normal and Laplace are the two earliest known continuous distributions in statistics and the two most popular models for analyzing symmetric data. In this note, the exact distribution of the ratio | X / Y | is derived when X and Y are respectively normal and Laplace random variables distributed independently of each other. A MAPLE program is provided for computing the associated percentage points. An application of the derived distribution is provided to a discriminant problem.
In this paper we consider the problem of testing some linear hypotheses in an extended growth curve model which is described for the data set of k clusters. The model includes the one whose mean structure consists of ...
