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...

Extensive decision-making during the vaccine preparation period is unpredictable. An account of severity disease, younger people with COVID-19 comorbidities and other chronic diseases are also at a higher risk pandemic. In this research article, preference ranking structure for recommended young who have been exposed to effects certain diseases. Multiple Criteria Decision-Making (MCDM) approach...

A major competitive advantage of production and service systems is establishing a proper maintenance policy. Therefore, maintenance managers should make maintenance decisions that best fit their systems. Multi-criterion decision-making methods can take into account a number of aspects associated with the competitiveness factors of a system. This paper presents a multi-criterio...

Multi attribute decision making methods are considered as one of the most useful methods for solving ranking problems. In some decision making problems, while the alternatives for corresponding criteria are compared in a pairwise comparison manner, if the criteria are inherently fuzzy, debates will arise in ranking alternatives due to the closeness of the values of the criteria. In this researc...

The PROMETHEE is a significant method for evaluating alternatives with respect to criteria in multi-criteria decision-making problems. It is characterized by many types of preference functions that are used for assigning the differences between alternatives in judgements. This paper proposes a preference of green suppliers using the PROMETHEE under the usual criterion preference functions. Comp...

Multi-period differences of technical and financial performances are analyzed by comparing five North African railways over the period 1990–2004. A first approach is based on Malmquist DEA TFP index for measuring total factors productivity change, decomposed into efficiency change technological changes. multiple criteria analysis also performed using PROMETHEE II method ARGOS software. These me...
