Query: Continuous occurrence theory   Usually gradual and continuous changes in entities will lead to appear
events. But usually it is supposed that an event is occurred at once. In this
research an integrated framework called continuous occurrence theory (COT) is
presented to investigate respective path leading to occurrence of the events in
the real world. For this purpose initially fundamental concepts are defined.
Afterwards, the appropriate tools such as occurrence variables computations,
occurrence dependency function and occurrence model are introduced and
explained in a systematic manner. Indeed, COT provides the possibility to: (a)
monitor occurrence of events during time; (b) study background of the events;
(c) recognize the relevant issues of each event; and (d) understand how these
issues affect on the considered event. The developed framework (COT) provides
the necessary context to analyze accurately continual changes of the issues and
the relevant events in the various branches of science and business. Finally,
typical applications of COT and an applied modeling example of it have been
explained and a mathematical programming example is modeled in the occurrence
based environment.
