A Goal Programming Linear Model for Simultaneous Project Scheduling and Resource Leveling - a Huge Civil Project as a Case Study(مقاله علمی وزارت علوم)

تعداد بازدید : ۱۷
We have a huge civic project, includes several sub-projects, which are divided into activities. This project is a project to rehabilitate 550,000 hectares of agricultural land in the provinces of Khuzestan and Ilam. The project has been divided according to the plots of land. The Jehad in Tehran is managing the projects. They need project scheduling as well as resource levelling and "lot-sizing". Levelling and lot sizing are the most important issues in utilizing the limited resources. For determining the scope and the size of those sub-projects as well as their parallel activities, so far, many models have been proposed. However, the models are weak either in higher resource utilization or in solving numerically the problems. In this paper, our effort has been concentrated on developing scheduling, resource levelling, and lot sizing model, based on balancing utilization of resources, so that the real size civil project could be solved within an acceptable duration time. This paper proposes a goal programming linear model for simultaneous project scheduling and resource levelling. This model determines the best schedule of sub-activities (optimal "lot size" of each sub-activity) to reach the minimum amount of diversion of resources consumed from the number of resources available for the entire periods of the planning horizon. In fact, if the best "lot sizes" have been taken, then minimum fluctuation of the active resources is reached. The proposed model has been used to schedule a project with 87 activities. This project has been scheduled and, accordingly, the optimal volume (the "lot size") of sub-activities have been determined for each activity at any period of time. In this way, only 4 resources out of a total of 32 resources are in shortage. In contrast, the scheduling of this project, using the CPM, results in a shortage of 13 resources.

The purpose of this study is to design a model to explain the indicators of brand value creation in the Iranian textile industry, to identify the dimensions, components and the indicators of brand value, measuring the dimensions, components and indicators of brand value. The research method in this study is descriptive-exploratory using ground data theory (grounded theory). The study population is the Iranian textile industry. The final research model includes the three main dimensions of customer, organization and government. The results obtained from the correlation of factors also showed that value from the customer's point of view, value from the organization's point of view and value from the government's point of view have the most role and effect in brand value development, respectively. Factors showed issues related to import and export, cost management, insurance and tax issues, administrative bureaucracy, human resources, technology, customer emotional factors and performance expectations factors are considered to be of higher rank and importance for brand value creation from the evaluators' point of view, respectively.

The aim of this study was to identify barriers to the implementation and use of Internet banking in Keshavarzi Bank. Due to the fact that qualitative data was first collected through study and interviews with experts, at different stages, different tools were used to collect the required data. In the first stage, data was collected through interviews with experts and systematic review. In the second stage, a questionnaire related to the content analysis method was evaluated. The statistical population of the study was 20 experts with master's and doctoral degrees and high work experience in banking management who were selected based on purposive sampling. The results show that, after reviewing the background and interviewing with 20 experts, 20 open source codes were identified by using theme analysis. The results of qualitative content analysis showed that 20 open source codes were important enough. Convergent validity was performed and the fit of the model was confirmed. However, it was found that the most important priorities were the inequality of the Internet banking system in the country's banking network, unpreparedness of the national information network, technological infrastructure problems used in websites, negative customer experience and their low trust, and fake and misleading sites. Banks should regularly update and retain their customers' communication gateway systems such as mailbox and digital and online space, to make customers more willing to receive Internet banking services in the future.

Information and communication technology (ICT) has provided a platform for the supply of innovative products and services. Therefore, the innovation ecosystem of communication technology (CT) has more searchable aspects separated from information technology (IT). This research aimed to provide insights into the state-of-the-art innovation ecosystem of the communication technology industry and suggests attitudes for future research. In this article, by review of more than 40 articles and chapters about the innovation ecosystem, the analysis has utilized data-driven tools, 173 questionnaires, and 20 specialized interviews with experts. The extracted factors of the research were analyzed using SPSS and AMOS software, and the research model was analyzed using the Adaptive Neuro-Fuzzy Inference System (ANFIS) in MATLAB software. The results show that the financial and economic factor has the most impact and the national and regional factor has the least importance in the innovation ecosystem model. The financial and economic factor is significantly different from other factors in terms of degree of importance.
