The multi-analysis modeling of a complex system is the act of building a family of models which allows to cover a large spectrum of analysis methods (such as simulation, formal methods, enactment,[Formula: see text]) that can be performed to derive various properties of this system. The High-Level Language for Systems Specification (HiLLS) has recently been introduced as a graphical language for discrete event simulation, with potential for other types of analysis, like enactment for rapid system prototyping. HiLLS defines an automata language that also opens the way to formal verification. This paper provides the building blocks for such a feature. That way, a unique model can be used not only to perform both simulation and enactment experiments but also to allow the logical analysis of properties without running any experiment. Therefore, it saves from the effort of building three different analysis-specific models and the need to align them semantically.

This research develops a discrete event simulation to investigate factors that affect key Air Force (AF) metrics for gauging the health of the AF spares supply chain and the impact on maintaining the mission capability of individual weapon systems. We focus on the unscheduled maintenance actions at a single air base for a single weapon system – the B-1 Bomber. A notional fleet of 16 aircraft at a single air base is modeled based on historical supply and maintenance data. To identify and quantify the effects of various factors, an experimental design is used for analyzing the output of our high-level discrete event simulation. This exploration shows we successfully capture several factors that significantly impact the key metrics used for the B-1 and have the potential to significantly increase mission capability for this weapon system.
