PHM Technology develops a number of advanced engineering software platforms. The Maintenance Aware Design environment platform or MADE - is a software platform that provides the engineering analysis capabilities required for decision optimization of the design and sustainment of safety & mission critical systems. Syndrome Diagnostics or SD is the worlds first causation-based fault detection and isolation (FDI) tool. MADE is a disruptive technology that offers significant process & technical improvements. Implementation can be achieved with qualitative & quantitative cost/risk mitigation benefits for users at each stage of the product life-cycle. MADE consolidates several different engineering applications onto a common system model that is set to become the industry standard for complex critical systems. MADE can be used for both new and legacy systems and platforms. Current standard practice in industry is to use simple spreadsheets to generate, capture and perform the analysis - MADE offers a cost efficient, integrated application that is structured to provide systemic risk mitigation for complex projects. Target MADE users are in industries where the financial risks of system reliability and availability are significant and increasingly borne by the Prime System Integrator (automotive, aerospace, defense, energy, marine, oil & gas, power, etc.) .

Enschede, Overijssel, Netherlands

Controllab makes digital twins to test control software and build training simulators for the high-tech systems and marine & offshore markets. Our customers develop machines that use lot of control software. Testing this software is done when the machine is assembled on site. Problems in the control software can lead to delays and even damage. Our digital twins are simulation models that closely resemble a real machine. By coupling these twins to the control software, our customers can do tests without a real machine. They can solve problems easily and deliver software that works right the first time. With in-house developed simulation tools and over 30 years of experience, we can build digital twins that resemble real machines very accurately. We have special technology to make these twins run in real-time and show the machine in 3D animation. This makes our digital twins ideal for interfacing with control software. Our digital twins are so realistic, customers even use them for training. If you are developing machines, start using our digital twins and enjoy the benefits they bring: • Quality: On a digital twin you can test operations that are too expensive or too dangerous to do on a real machine. • Efficiency: On a digital twin you can instantly change anything. This means you can work much faster. • Costs: With a digital twin there are no operational costs of the real machine.
