Real option is one of most promising and crucial concepts in corporate valuation and budgeting process. They are very similar to financial options except that their intrinstic values are calculated based on a company’s practical flexibilities rather than financial contracts. Most previous publications in this field are related to upstream sectors of oil, gas, or mining as well as high-tech industries. The application of this concept in chemical industries has been poorly investigated, and the majority of those limited number of papers have evaluated real options in down-stram sectors. Thus, the application of real options in midstream parts of chemical industry was not thoroughly... 

For sometimes researchers and practitioners have realized that the traditional success criteria, known as iron triangle (time, cost, quality), are not adequate indicators to align a project execution with the long term success trend of an organization. Many other success criteria in addition to time, cost and quality of a project can negatively or positively affect the long term success of an organization. Evaluating the project life cycle success is to some extent more judgmental and usually there is no agreed upon measures defined prior to the project execution. There are many stakeholders affected or involved in the life cycle of a project like; owner, contractor, operator, customers,... 

Decision making for planning a petrochemical plant is a difficult task, particularly when decisions are required to be made under constraints and different objectives. Final purpose of current research is to develop a reliable model for selecting limited petrochimal products among all potential alternatives under different constraints, considering two desired objective functions; Maximizing economic gain and minimizing safety risk. The powerful tool of multi objective decision making has been used for solving the proposed model. The developed model has been applied to Jam Petrochemical Company as a case study and the acquired results found to be successful.

 

Despite the growth in Iran’s petrochemical production, most of the plants are concentrated upstream; although the government has made various interventions to promote industrial development. The literature review shows that government intervention is necessary to solve market failures, especially in developing countries; but it should be tailored to the specific context and especially the distribution of the power. Most experts believe that the cause of the above phenomenon is feedstock rent and the reason for its continuation is the political influence of petrochemical companies. While not rejecting this view, we try to provide policy recommendations by looking more closely at the issue and... 

In this study, we introduce a systematic approach for valuation of Technology development projects by applying a discrete model of real options valuation. This framework is then applied to a real technology development project. The estimate of volatility is the most important argument that it is difficult to calculate. Data from the project’s feasibility study is gathered and classified in an appropriate format to be ready for simulation. Then uncertainty parameters are identified. The data is separated and their impacts on annual cash flows are considered. Volatility of the whole project is estimated to be relatively high. This is an advantage for the proposed method. In this project,... 

Planning orders and inventory is one of the most important issues in the planning of petrochemical production. Considering the customization of this industry, orders planning includes a large part of it. Also, in order to reduce the great cost of inventory storage, planning to reduce inventory must be considered. In this regard, we intend to present a model with simultaneous consideration of orders and inventory planning in this research, the ability to decide on acceptance of orders and determine the level of production of products in conditions of uncertainty of demand with random trapezoidal demand in each period can be assumed. This model will practically play a key role in improving... 

Golpayegan Qaed Basir Petrochemical Company is one of the lucrative and entrepreneurial companies in Iran. Every day in this complex, a large amount of wastewater is being generated and transferred to the evaporative lag after the primary and secondary purification outside the complex and it is not restored. Considering the growing importance of surface and underground water resources, reuse of wastewater is a valuable production. In this research, the optimization of the sewage treatment system of the complex was evaluated by replacing the chemicals in the primary purification unit and also by using chloride-ferric and trickling filter for tertiary purification(treating) of the... 

Iran's petrochemicals exchange has experienced regular excess demand occurrence in recent years which has resulted in most transactions being done at ceil price specified by Iran's mercantile exchange. This study shows that the mechanism determined by Iran's mercantile exchange for doing transactions has given people the incentive to state their initial demand higher than their real demand in order to be able to gain their real demand in market. In order to do this, I have used data related to all transactions done in Iran's petrochemical exchange during March 2013 and March 2016 in a panel logit model and show that monopolistic power used by suppliers and the probability of excess demand... 

The project schedule is used as a key tool for managers to measure the progress of the project and prevent the deviation of the project from achieving its goals.Project scheduling started with manual methods. After a while, due to the increase in the size of projects and their complexity, the efficiency of traditional methods decreased. After the advances in computer sciences, scientists and experts had moved towards intelligentization and automation.During the past three decades, despite the attention of both academic and industrial fields towards automatic planning and scheduling of projects, Most of the researches focused on construction projects, and unfortunately, a few attentions have...
