Multi-use simulation models

Multi-use simulation models is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Multi-use simulation models rather than just read about it. In short: The concept of multi-use simulation models relates to the notion of pre-designed templates that are developed for use in simulation projects that simulate repetitive activities. These models can be perceived as “Building Blocks” which are designed for a specific purpose.

Key takeaways

Multi-use simulation models belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Multi-use simulation models to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Multi-use simulation models from memory before moving on to harder problems.

Reference excerpt

The concept of multi-use simulation models relates to the notion of pre-designed templates that are developed for use in simulation projects that simulate repetitive activities. These models can be perceived as “Building Blocks” which are designed for a specific purpose. The chief objective of this concept is to facilitate the conceptualisation and understanding of the simulation model by non-specialists. In practice, the concept can be implemented in different contexts, mainly in the construction industry; as those who work in the development of a simulation project are interested in the efficiency and effectiveness of their simulation model rather than its underpinning mathematical complexity. The development of multi-use simulation models has been addressed by several studies during the last two decades. The first significant trial to make a general-purpose simulation was presented by Hajjar and AbouRizk, 1997. They developed a general purpose simulation model to be used in the estimation and planning of earth moving operations based on reusable templates. Other research was to use reusable templates in preparing draft scheduling for the construction of similar projects. The templates were made to encode much of the knowledge dealing with activity scoping and sequencing and the use of special activity in planning structures. Similarly, an interactive simulation system to be adapted by a beginner level user was developed in 1999. This system was designed to provide easy access and a manipulative environment for studying, analyzing and simulating construction processes. He used a simple and attractive graphical user interface to overcome the potential resistance of the user to simulation as an analytical tool.

Notes

Worked examples

Example 1 — a first encounter with Multi-use simulation models

Start with the simplest possible case. Write down what Multi-use simulation models claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Multi-use simulation models before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Multi-use simulation models ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Multi-use simulation models

In research: Multi-use simulation models appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Multi-use simulation models in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Multi-use simulation models is common in secondary-school and first-year university syllabi. It links to neighbouring topics Simulation, so understanding it makes those chapters shorter.
In everyday life: Look for Multi-use simulation models outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
