Failure Mode Effect Analysis (FMEA) is one of user friendly and handy tool available in the hands of the process industries to identifying and eliminating the potential failures in systems, processes and designing. In this FMEA method prioritization of the failure modes are based on Risk Priority Number (RPN). This RPN can be calculated by multiplying the scores of various risk factors and cate...

Although PM was basically created to treat subjective comparisons, given exact values can be converted to Potential Method flow. A new feature of PM is a parameter called FlowNorm which helps to treat problems where each criterion has its own measurement scale. Complex hierarchial structures and problems modelled by decision tables can be handled. Incomplete data, such as incomplete belief, is ...

The candidate selection process involves thoughtful empirical decisions which determine the best fit from a pool of contesting candidates. A wide range of criteria is used to assess the candidates. This paper utilizes an improved PROMETHEE II (Preference Ranking Organization Method for Enrichment Evaluation) methodology which efficiently establishes its applicability and potentiality to solve s...

Outranking relations are most often built using a concordance-discordance principle. Such relations are, in general, neither transitive nor complete. This is not to say that the concordance-discordance principle does not impose some "structural" restrictions on these relations. We show why this question may be of some importance for analyzing the various techniques designed to build a recommend...

Like most other fundamental mechanical components which form the basis of many mechanical systems, springs have existed since the Bronze Age for storage or release of energy, absorption or utilization of vibration, relaxation or absorption of impact force and when unloaded, return to the original position or to the original shape. Quality, service requirement, performance as well as durability ...

The notion of comparatively positioning objects with respect to each other is commonly called ranking. With respect to databases, the ranking issue is closely associated with data retrieval. Yu, Hwang, and Chang (2007) highlight that with the myriad of databases situated online, retrieving relevant data is problematic; in reality it becomes an online ranking problem (Chaudhuri, Das, Hristidis, ...

This work first studies the effects of several Low Impact development methods on urban flood control. The Analytic Hierarchy Process-Preference Ranking Organization Method for Enrichment Evaluation (AHP-PROMETHEE) combination method is then used to select best design. A drainage system in Golestan town Semnan under a 5-year return period investigated as case study. LID are selected based region...
