This paper presents a formal framework for process-oriented modeling and analysis of organizations. The high expressivity of a sorted predicate logic language LPR used for specifying process-oriented models allows representing a wide range of process-related concepts (e.g., tasks, processes, resources), their characteristics and relations over them, which are described in the paper. Furthermore...

in this paper at rst, a history of mathematical models is given.next, some basic information about random variables, stochastic processesand markov chains is introduced. as follows, the entropy for a discrete timemarkov process is mentioned. after that, the entropy for sis stochastic modelsis computed, and it is proved that an epidemic will be disappeared after a longtime.

This paper presents a data envelopment analysis (DEA) model combined with Bootstrapping to assess performance of one of the Data mining Algorithms. We applied a two-step process for performance productivity analysis of insurance branches within a case study. First, using a DEA model, the study analyzes the productivity of eighteen decision-making units (DMUs). Using a Malmquist index, DEA deter...
