Abstract
There is often a large gap between the planned value of investment in a project (capital expenditure [CAPEX]) and financial implementation of this. This fact creates a mismatch between the net present value (NPV) of the planned project and the outcome achieved. Depending upon the company’s project portfolio, this could even threaten its solvency. Therefore, a quantitative risk analysis that takes into account different possible scenarios for these investment values is extremely important to statistically measure the real value of a project. The aim of this paper is to present the reasons for mismatch between planned and final investment values. Although the results are valid for projects in the petrochemical and refining sector, also called downstream in the oil industry, the methodology can be applied upstream, or even to other industry branches.
期刊介绍:
The journal Theory and Applications of Categories will disseminate articles that significantly advance the study of categorical algebra or methods, or that make significant new contributions to mathematical science using categorical methods. The scope of the journal includes: all areas of pure category theory, including higher dimensional categories; applications of category theory to algebra, geometry and topology and other areas of mathematics; applications of category theory to computer science, physics and other mathematical sciences; contributions to scientific knowledge that make use of categorical methods.
