Markov Chain theoretic approach to modelling industrial safety: some results from Nigeria oil and gas industry

Supply-chain Management Issues in the Oil and Gas Industry

The oil and gas industry is involved in a global supply-chain that includes domestic and international transportation, ordering and inventory visibility and control, materials handling, import/export facilitation and information technology. Thus, the industry offers a classic model for implementing supply-chain management techniques. In a supply-chain, a company is linked to its upstream suppli...

Quantitative risk management in gas injection project: a case study from Oman oil and gas industry

The purpose of this research was to study the recognition, application and quantification of the risks associated in managing projects. In this research, the management of risks in an oil and gas project is studied and implemented within a case company in Oman. In this study, at first, the qualitative data related to risks in the project were identified through field visits and extensive interv...

System Safety of Gas Turbines: Hierarchical Fuzzy Markov Modelling

Network DEA Approach to Organizing and Job Evaluation Process Assessment: Real Case of Iranian Oil and Gas Industry

All organizations have structure. Researchers emphasized the importance of the organizational structure to achieve the goals and mission of an organization. Thus Performance assessment of organizing is essential for managers and decision makers to find weaknesses and eliminate them. Organizations are designed by different methods and process, based on same principles and theories. In this study...

Some Number Theoretic Results

This note consists of two rather separate topics . In §1 we generalize a topic from combinatorial number theory to get an order of magnitude for the number of elements in a maximal set of residues (mod p) such that sums of different numbers of elements from this set are distinct. We show that the correct order is ep'" 3 although we are unable to establish the correct value for the constant c . ...
