throughout life cycle of oil production wells, it is imperative to have production optimization and real response time to rapid changes of well conditions and more understanding of subsurface otherwise it is the matter of expenditure losing. smart well capabilities meet aforementioned issues. however there is a key concern in managers' mind that they have limited budget and several fields' docu...

An approach for the analysis and management of multiple criteria critical infrastructure problems is put forth. Nuclear waste management involves complex tradeoffs under uncertainty. Among all waste either generated by nature or human activities, radioactive nuclear waste is the most toxic to human health and difficult to manage: it is known that some nuclear waste material will be radioactive ...

Multi-criteria analysis (MCA) is being used in the Sediment and Society project as a tool for communicating impacts, as a tool for documenting differences in interests of stakeholder groups, and as a tool for ranking complex sediment remediation alternatives. Ranking of alternatives in MCA requires impacts to be (i) standardised, and then (ii) weighted against one another. This Technical Brief ...

The convergent validity of ®ve multiattribute weighting methods is studied in an Internet experiment. This is the ®rst experiment where the subjects created the alternatives and attributes themselves. Each subject used ®ve methods to assess attribute weights ± one version of the analytic hierarchy process (AHP), direct point allocation, simple multiattribute rating technique (SMART), swing weig...

This article presents a financial scoring model estimated on Czech corporate accounting data. Seven financial indicators capable of explaining business failure at a 1-year prediction horizon are identified. Using the model estimated in this way, an aggregate indicator of the creditworthiness of the Czech corporate sector is then constructed and its evolution over time is shown. This indicator a...

Landslides, as geological hazards, cause significant casualties and economic losses. Therefore, it is necessary to identify areas prone to landslides for prevention work. This paper proposes an improved information value model based on gray clustering (IVM-GC) for landslide susceptibility mapping. This method uses the information value derived from an information value model to achieve suscepti...

Korean government now establishes a new strategic ten-year plan that will cover the period from 2006 through 2015. In this paper, we prioritize the relative weights of energy technologies in terms of the national greenhouse gas plan using the AHP/DEA hybrid model. This model, which is composed of the analytic hierarchy process and data envelopment analysis, represents one of the multi-criteria ...

All the basic models in data envelopment analysis (DEA) divide decision making units (DMUs) in two groups: efficient DMUs and inefficient DMUs, and lack of discrimination of efficient units is a serious problem. Also in spite of completely ranking units in analytical hierarchy process (AHP), the process of making pairwise comparison matrix is based on experts’ choices and it causes error and in...

Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis does not provide an analytical means to determine the importance of the identified factors or the ability to assess decision alternatives according to these factors. Although the analysis successfully pinpoints the factors, individual factors are usually described briefly and very generally. For this reason, SWOT analysis possesse...
