Monitoring complex electro-mechanical processes is not straightforward despite the arsenal of techniques nowadays available. This paper presents a method based on Adaptive-Network-based Fuzzy Inference System (ANFIS) to estimate eccentricity of its spinning axis. The method is experimentally tested on an ultra-precision rotating device commonly used for micro-scale turning. The developed model ...

This paper presents a mathematical model of inventory control problem for determining the minimum total cost of multi-item multi-objective inventory model with fuzzy estimated price dependent demand, fuzzy deterioration and possible constraints. Here, three constraints we have taken; they are warehouse space constraint, investment amount constraint and the third constraint is the percentage of ...

In this paper, we introducea deterministic Economic Order Quantity Inventory Modelwith exponential demand rate, Weibull Distribution for deterioration and time dependent holding cost in crisp and fuzzy environment.Also each cycle Shortages are allowed and partially backlogged to suit present day competition in the market objectives. The backlogging rate is variable and as depends on the length ...

In this paper, a single-vendor and multiple-buyers’ integrated production inventory model is investigated where demand of the item at buyers’ location considered as interval type-2 fuzzy number (IT2FN). Deterioration rate assumed to change in accordance with weather conditions particular region. It relies upon values certain attributes that have direct influence on extent deterioration. These p...

In this study we have discussed a fuzzy eoq model for deteriorating products with time varying deterioration under inflation and exponential dependent demand rate. Shortages are not allowed in the impact of is investigated. An inventory used to determine whether order quantity more than or equal predetermined declining items.The optimal solution existing derived by taking truncated taylor’s ser...

Background: Advances in information technology and data collection methods have enabled high-speed collection and storage of huge amounts of data. Data mining can be used to derive laws from large data volumes and their characteristics. Similarly, fuzzy logic by facilitating the understanding of events is considered a suitable complement to scientific data mining. Materials and Methods: The pre...

Does Mental Productivity Decline with Age? Evidence from Chess Players We use data on international chess tournaments to study the relationship between age and mental productivity in a brain-intensive profession. We show that less talented players tend to leave the game in the earliest phases of their career. When the effects of age on productivity vary with unobserved ability, commonly used fi...

The 2014 Indian general election marked a single party – the Bharatiya Janata Party, winning a majority of seats in Lok Sabha, the first time since the 1984 election. The Congress, the other main national party, suffered its worst ever defeat. This election was termed by some as a 'critical election' signalling the advent of a new phase of a ‘BJP dominated’ party system in India. In this paper,...
