Petroleum industry of Iran has provided one of the best opportunities for employees, but occupational exposures leading to chronic diseases such as cancer are high in the field. Ministry of Petroleum has owned an organization, which covers the personnel with health insurance, called “Petroleum Industry Health Organization” (PIHO). PIHO and Health, Safety & Environment (HSE) units play significant roles in providing the employees with health services. However, there is lack of a unique system specifying occupational cancer control. Cancer is a major cause of morbidity and mortality worldwide. On the other hand, negative impressions of cancer and heavy costs of patient’s treatment have forced the ministry to pay appropriate attention to this chronic disease. This paper aims to identify structure and design a framework for a system to occupational cancer control in Iranian petroleum industry. Due to the vast dynamic complexities (multi-dimension nature of cancer, joint exposures, and the delay between exposure and incidence) and behavioral complexities (various stakeholders and actors) in the problem, we have adopted Soft System Methodology (SSM) in order to study the current situation. We reached an agreement with the problem owner on a rich picture, CATWOE analysis, and a root definition on how this surveillance system would be considering the real world circumstances.The results were obtained through many sessions with problem stakeholders even with conflicting interests. The results revealed that it is necessary to make some changes in the actors’ information systems (occupational hygiene and medicine, hospitals and the ministry’s Pension Organization), with an emphasis on identifying and analyzing carcinogens and cancer patients in order to improve the problem situation.

Nowadays, ICT infrastructures and applications have been developed because of its capabilities in responsing to the needs of business. These capabilities cause ICT to be used as a simple fying and empowerment tool to achieve. Recently, the ICT infrastructures have been developed to the rural areas through the Rural ICT Plan. Using ICT capabilities for rural empowerment, decreasing rural poverty and decreasing rural problems are the final goal of this plan. This plan had good advancements in hardware and network dimensions, but there is no integrated methodology for developing its applications. Therefore, in this paper, based on the enterprise architecture issues, an architecture framework was introduced based on rural ICT infrastructure. The proposed framework mainly focuses on the rural supply chain in agriculture domain, because of its importance as a rural core process. The grounded theory is the research methodology of this study and the resulted architecture framework was developed in three layers. Finally, the framework was compared with the common enterprise architecture frameworks.

The purpose of this study is to explain the ability of the computer simulation methodology to improve productivity of a production system. At the beginning, it demonstrates how simulation can be employed in productivity analysis. In this regard, a case study approach was used and the proposal methodology was implemented to represent the simulation capability to enhance the productivity in the case study.
An explanation of the existing system was presented and the corresponding model called AS-IS model was designed, then the model was runned and the output was analyzed. The results of the study showed the bottlenecks and performance measures of the existing system and the initiated two models according to the simulation output, called TO-BE models.
The results obtained from the simulation experiment showed the performance measure in the TO-BE models. The manager of the company, has selected the TO-BE2 model as the best alternative based on the economical and others measure.
