Analysis and evaluation of agricultural systems use these criteria: energy, economic, agronomy, environmental conservation and time. Because of time importance indicator for reducing timeliness cost, project scheduling techniques are used. Graphical Evaluation and Review Technique (GERT) is widely used as a tool for managing projects. In this research GERT Networks were used and operations scheduling of sugarcane production (land preparation, planting and preserve operations) in Khuzestan province of Iran as a case study was analysed, by using WinQsb software. Critical activities, events and path were determined. The earliest project completion time is 214.03 days. The results show a high potential for operations scheduling of sugarcane production.

Graphical Evaluation and Review Technique (GERT) is a systems analysis technique for project management. GERT provides a visual picture of the system and helps to analyse the system in a less inductive manner. Therefore, the purpose of this paper is studying the application of project scheduling in agriculture, for operations scheduling of sugarcane production (preserve operations, harvesting and rationing) using classical GERT method in Khuzestan province of Iran. Results showed that the network model was able to answer any statistic all the questions concerning the project. GERT networks are increasingly becoming a powerful tool for modelling, scheduling, planning, controlling and analysing of agricultural mechanization projects.

This paper describes exploratory research regarding leadership and communication within undergraduate engineering design teams. The case study was performed on student design projects of one and two semester duration to begin to assess the impact of project length on leadership and communication within the design teams. Data was collected using a survey that was given to the participants in three capstone design projects in Clemson University’s senior design course. The survey was administered within one month of course and project completion. While there were differences in the communication and leadership patterns between the teams, there were other possible influences beyond the project length such as team size and organization, organizational and geographic distribution, and the nature of the product. As a result, further research is proposed to study leadership and communication structures within undergraduate teams and multi-team systems (MTS).

Dependence of conventional agricultural systems on chemical fertilizers and pesticidesmakes agricultural systems less stable and important drift polluters influencing to theregional and global sustainability. This problem made human being think about thealternative systems: agricultural systems that mimic natural systems and are friendly to theenvironment; those have higher economical efficiency concerning production level andcosts. The objective of the present study was sustainability assessment and comparison oforganic and conventional system with special focus environmental and economicalperformance. The case study consisted of two organic and conventional olive producingfarms in the South of Italy. The method used for sustainability assessment wasEnvironmental Accounting Information System (EAIS) that integrates togetherenvironmental (soil organic matter, soil erosion, genetic and landscape biodiversity,EPRIP, etc ) and economical indicators (gross margin). Data used for assessment ofEAIS indicators values were mainly collected from: farm economic-accounting systems,interviews, farm maps, area public organizations, bibliographical sources, farm nutrientaccounting systems, observations and field assessments and chemical soil analyses. Theindicator values measured into two farms were compared to theoretical or referenceindicator values. Based on indicator assessment it was concluded that organic olivegrowing farm had better performance than conventional farm.

Current global markets are volatile, where companies are striving to deliver greater quality, more customization, faster response, more innovative designs and lower prices. New models need to be introduced in the market more frequently, which has given momentum for designing family of products. Development of family of Products using a platform approach requires making decisions regarding platform selection and trade-off studies, which require analysis and evaluation of performance for the entire family instead of an individual products. One of the first steps in performing these activities require development of solid models for the entire family quickly and automatically as platform and family member configurations and size are changed. This paper presents an approach to automatically generate CAD models for a family of products. In the approach, a product family template that integrates configuration and parametric design information is presented. The template is implemented in the developed Product Family CAD (PF-CAD) module for Pro/E. A coffeemaker product family is used as a case study to automatically generate solid models of product family members from customer input.
