Функциональное моделирование проекта и имитационный эксперимент при случайных длительностях выполнения операций. Функциональное и имитационное моделирование работы производственного участка цеха

1.1. Задание 1. Функциональное моделирование проекта и имитационный эксперимент при случайных длительностях выполнения операций.

Цель. Средствами системы Arena разработать функциональную модель процесса, имеющего следующее содержательное описание.

Требуется:

1. С учетом технологической последовательности работ построить сетевой график выполнения этих работ в представлении узел-операция.

2. Средствами системы Arena на основе построенного сетевого графика разработать функциональную модель проекта.

3. Провести имитационный эксперимент, выявить основные временные характеристики проекта.

4. Создать отчеты по результатам имитационного эксперимента и экспортировать их в Word.
