Short-term scheduling of crude oil operations in refinery with high-fusion-point oil and two transportation pipelines

In some refineries, storage tanks are located at two different sites, one for low-fusion-point crude oil and the other for high one. Two pipelines are used to transport different oil types. Due to the constraints resulting from the high-fusion-point oil transportation, it is challenging to schedule such a system. This work studies the scheduling problem from a control-theoretic perspective. It proposes to use a hybrid Petri net method to model the system. It then finds the schedulability conditions by analysing the dynamic behaviour of the net model. Next, it proposes an efficient scheduling method to minimize the cost of high-fusion-point oil transportation. Finally, it gives a complex industrial case study to show its application.     

Determinants of workers’ remittances: An empirical investigation for a panel of eleven developing Asian economies

We explore the key motives of migrant workers’ remittances from abroad for 11 major Asian migrant‐sending countries. Using panel regressions, we find that relative higher growth rate, interest rate and capital market returns of home over the host, investment, financial deepening at home have significant impact on remittance inflows into Asia, along with higher per capita incomes and international crude oil prices. With incorporation of per capita incomes and lagged impact of remittances, we observe an emergence of consumption motives to remit. Therefore, we conclude that both investment and altruistic motives are the driving forces for remittances inflows into the Asian economies.     

Relationship between oil,stock prices and exchange rates: A vine copula based GARCH method

In this paper, we apply a vine copula approach to investigate the dynamic relationship between energy, stock and currency markets. Dependence modeling using vine copulas offers a greater flexibility and permits the modeling of complex dependency patterns for high-dimensional distributions. Using a sample of more than 10 years of daily return observations of the WTI crude oil, the Dow Jones Industrial average stock index and the trade weighted US dollar index returns, we find evidence of a significant and symmetric relationship between these variables. Considering different sample periods show that the dynamic of the relationship between returns is not constant over time. Our results indicate also that the dependence structure is highly affected by the financial crisis and Great Recession, over 2007–2009. Finally, there is evidence to suggest that the application of the vine copula model improves the accuracy of VaR estimates, compared to traditional approaches.     

Nothing Tastes as Local: Jordanians’ Perceptions of Buying Domestic Olive Oil

To date, little is known about how consumers perceive local and foreign olive oil. This study was conducted with the intention of exploring key trends in Jordanian consumers’ perceptions toward local olive oil and to examine whether they are ethnocentric toward purchasing their local olive oil in the era of the Arab Spring. The research design is a combination of quantitative with a qualitative technique to support and expand on the research findings. Data were collected from a total number of 196 Jordanians who live in Amman city. The results revealed that Jordanians are loyal to their country’s olive oil; they expressed strong ethnocentric tendencies toward purchasing it, and their purchasing tendencies are influenced by nationalism. Jordanians ranked their local olive oil as the best worldwide. This article provides original insights into the development and marketing strategies for local and global olive oil producers in the Jordan market and other Arab country markets.     

The Success Factors of Food Events: The Case Study of Umbrian Extra Virgin Olive Oil

Gastronomic events are an important part of the “Made in Italy” and a vital tool for rural development. The aim of the study is to identify the complexity of the factors that determine the success of a food event. The authors, after state-of-the-art analysis of the event marketing, formulate the hypothesis of a causal model and form a data collection during the “open oil mills” in the Umbria region. Through in-depth interviews the participants were asked to express themselves about the importance and interest attributed to some aspects directly related to the theme of the event, and finally to indicate the degree of satisfaction and the likelihood of some of their future behavior. Statistical analysis based on structural equation models allowed the authors to highlight which aspects are significant in order to confirm the assumptions made. Results provide guidance for management decisions and organization of food and wine.

Petromin: The slow death of statist oil development in Saudi Arabia

The paper recounts the history of Saudi Arabia's first national oil company, Petromin, which was originally supposed to take the place of foreign-owned Aramco. As a result of Petromin's inefficiency and personal rivalries among the Saudi elite, however, Petromin was progressively relegated to the sidelines in favour of a gradually ‘Saudiised’ Aramco. As a result, the organisation of the Saudi oil sector today is very different from – and more efficient than – that of most other oil exporters in the developing world. The paper concludes with a tentative taxonomy of national oil companies, based on the circumstances of nationalisation.
