data envelopment analysis (dea) is a non-parametric approach for performance analysis of decision making units (dmus) which uses a set of inputs to produce a set of outputs without the need to consider internal operations of each unit. in recent years, there have been various studies dealt with two-stage production systems, i.e. systems which consume some inputs in their first stage to produce ...

Extending the idea of Even and Lehrer (2014) [3], we discuss a general approach to integration based on a given decomposition system equipped with a weighting function, and a decomposition of the integrated function. We distinguish two type of decompositions: sub-decomposition based integrals (in economics linked with optimization problems to maximize the possible profit) and super-decompositio...

We present a new approach to trend/cycle decomposition of time series that follow regime-switching processes. The proposed approach, which we label the “regime-dependent steady-state” (RDSS) decomposition, is motivated as the appropriate generalization of the Beveridge-Nelson (1981) decomposition to the setting where the reduced-form dynamics of a given series can be captured by a regime-switch...

A new method, the time decomposition in modified conceptual models (MCM) is described. There are introduced two approaches to model the function execution time in MCMs, necessary to decomposition: the execution-state approach and the execution-path approach. There are also described transformations necessary to manage the resolution of MCMs. There is also introduced the concept of preliminary s...

This paper introduces a novel approach to integrals with respect to capacities. Any random variable is decomposed as a combination of indicators. A prespecified set of collections of events indicates which decompositions are allowed and which are not. Each allowable decomposition has a value determined by the capacity. The decomposition-integral of a random variable is defined as the highest of...

In this paper two external schema generation algorithms are presented. These algorithms are defined in the framework of the new external schema definition methodology for OODBs put forward in (Samos, 1995); they generate an external schema from a set of classes selected from those existing in an external schema definition repository. Their main characteristic is that they avoid the generation o...

for energy saving retrofit projects, its economics are usually evaluated in terms of capital investment and payback time. the capital investment is in direct relation to the total heat recovery area of the network and the payback time factor is base on both the area and the energy savings. the debottlenecking is an increased throughput, which can be profitable in economic sense. the combination...
