Stories and insights from the team behind HASH

Modeling with System Dynamics

System Dynamics models are a powerful tool for visualizing and modeling complex systems. They break down a model into abstract or concrete quantities (stocks), and the rates at which they change (flows). HASH’s System Dynamics library makes it easy to incorporate these types of models into your simulations. With the HASH library, models are always […]

Optimization Experiments

Often, the goal of creating simulations is to find the optimal combination of policies or parameters for achieving some objective: e.g. to maximize revenues, minimize costs, improve the efficacy of an advertising campaign, or boost throughput in a factory. While HASH makes it easy for you to modify parameters and explore your simulation, once the […]

UK Housing Model

One of the great strengths of multi-agent simulations is that they can capture a high degree of heterogeneity (diversity). Different agents in a simulation can have different properties and attributes, producing radically different macro-level phenomena. An example of this is the housing market — when you’re searching for a new home, different types of homes […]

Simulate and Optimize RPA Deployments

Robotic process automation (RPA) is an emerging field that promises to change the way organizations are run. RPA is a methodology and technique for automating basic business tasks with ‘bots’ that records users’ actions and infer the steps necessary to reproduce it. Repetitive tasks, like scraping websites or downloading photos, can be easily automated without […]

Modeling with Networks

Networks are a fundamental pattern within simulation modeling. Many important systems can be represented as networks: Transportation systems such as bus and subway lines Digital systems such as servers and distributed computing systems Social systems such as social networks and organizational charts  The Networks Library allows you to easily model networks. Similar to HASH’s existing […]

Extending the Uniswap Simulation

We’ve modified the Uniswap simulation to account for more use cases, more complex logic, and more trading partners. One of the benefits of building a HASH simulation is maintainability and extensibility. You can add and modify behaviors over time, giving your agents new abilities and simulating new situations. In the initial release of our Uniswap […]

Simulating Constraints: A Framework for Process Optimization

Simulating process models is a powerful technique for understanding and optimizing work processes. And like most powerful techniques, it’s important to have a framework for applying it, to help use it in a way that’s beneficial and aligned with management objectives. What follows is a suggested approach for using simulations to generate insights about your […]

Business Process Modeling in HASH

Today we’re launching our first plugin for HASH, which provides a graphical user interface for the easy modeling and simulation of business processes and operations. Drag ‘n’ drop build processes, and easily simulate them in practice.

Vaccine Distribution Scenario Modeling

Optimizing vaccine allocation is a critical task – improving the distribution of vaccines could save tens of thousands of lives over the coming months. In partnership with researchers at the Virginia Modeling, Analysis, and Simulation Center, we created a simulation of the vaccine distribution process.

Simulating Short Squeezes

We wanted to demonstrate the dynamics of the Battle of GameStop™ so we put together a simulation of the sharp escalation of price that can occur when an irresistible force (legally needing to cover your shorts) meets an immovable object (the combined will of thousands of Redditors).
