Commercial simulation project failures

Discrete-event simulation has been around for a long time. Growing computation power has aided the application of discrete-event simulation in recent years. This is especially true with regards to visualization and animation of the models themselves. However, the method, related […]

ERP software for retail business

A retail business sells products or services to consumers for either personal, household, or business use. Retail businesses can be small or big and can e.g. take the form of independent stores, chain stores, or online stores. Retailers can choose […]

Growing relevancy of supply chain analytics

Supply chain analytics will enjoy growing relevancy. There are several reasons for why supply chain analytics is becoming increasingly relevant to industry. Some reasons that I will point out are increasing supply chain complexity, rising customer expectations, and increased relevancy […]

PUSH production and analytics

Push-based production planning makes greater benefit of advanced analytics compared to pull-based production planning and control. The reasons for this are manifold, but include the fact that push-based production planning involves forecasting of demand and subsequent production and capacity planning […]

Job shop scheduling challenges

Mathematical programming is a powerful tool for supply chain management and production planning. It can also be used for job shop scheduling, next to other popular application domains such as network design and pricing. Application of mathematical programming to job […]

Visualizing stats with salabim (DES, Python)

Having introduced salabim for discrete-event simulation (DES) in Python I want to follow-up on its stats-related functionality. I do so in today’s blog post: Stats with salabim! Discrete-event simulation, job shop, and Python Discrete-event simulation is one of several simulation […]

Job shop simulation with salabim in Python

Following my recent article on job shop simulation in Python with SimPy I was asked to also publish an example covering salabim in Python. SimPy and salabim have similar syntax, with some differences. Both are used for discrete-event simulation (DES) […]

Visualizing SimPy job shop simulation

I am following up on my recent simplified job shop simulation example in SimPy. Today I want to show you how you can collect simulation data in a SimPy simulation model. I will use the data for data visualization. As […]

Discrete-event simulation (DES) use cases

Discrete-event simulation (DES) can be applied to a wide range of industries and domains where events occur in a discrete, sequential manner. It is applied when a system is so complex that it cannot be understood or solved with analytical […]

Job shop simulation in SimPy

Today another technical post with a quick introduction to job shop simulation in SimPy – another discrete-event simulation model development option in Python. This package is among my favorite simulation tools. You can see some examples that I built with […]
