Today ProcessMaker and OpenRules announced a new partnership that provides our customers with an integrated business process and decision management solution. The partnership adds high performance decision services created in OpenRules and deployed as AWS Lambdas to business applications built with ProcessMaker. It unlocks a powerful new level of sophistication for process, workflow, and business rules designers around the globe. This webinar demonstrates an implementation of a loan origination process in ProcessMaker that utilizes complex decision services built in OpenRules. Read Press Release.

Inside/Outside Production Planner
Last week I created a “Worker Planner” that has a nice GUI deployed on Apache Tomcat and it works in sync with a remote Scheduling Decision Service deployed as AWS Lambda. The scheduling service was implemented with JavaSolver and a constraint solver included into JSR331. My objective was to demonstrate that these days with cloud-based deployment it is not so difficult to create an end-to-end full-scale decision optimization service. I also wanted to show how to apply powerful Linear Solvers to crack traditionally complex production scheduling problems. So, two days ago I took a well-known problem that is described in this example: Continue reading
Building a Live Worker Scheduler
There are already several good responses to the DMCommunity’s April-2020 Challenge “Doctor Planning”. Below I am describing how I tried to use this challenge to create a complete decision optimization service. I ended up with a working Worker Scheduler that shows a solution for this particular challenge in Fig. 1 (click to open):
Deploying Decision Models as RESTful Web Services and Docker Containers
OpenRules Decision Manager can be deployed a business decision models as a RESTful web service that accepts HTTP requests at your local or remote server and produces with proper responses in the JSON format. As usual, you create and test your decision model in Excel and then simply add the property “spring.boot=On” to the file “project.properties”. Then you only need to double-click on the provide file “runLocalServer.bat” (the same for all models). Continue reading
OpenRules at AWS
We a
re aggressively making OpenRules-based services available from cloud environments such as Amazon EC2. In particular, we’ve just re-deployed our Decision Model Analyzer from a 3rd party remote Tomcat to Amazon. It was just a very simple reconfiguration, but the effect is really positive: the Analyzer is now much faster and much more reliable. You may try it yourself without any registration or fee: simply click on the button on the right.
The source code of the Analyzer is included in the OpenRules standard release and can be considered as an example of how to deploy OpenRules web applications created using OpenRules Dialog to cloud. Another example is the game “Nim” that you may play now from the cloud by clicking on the image below: Continue reading
Decision Microservices with Spring Framework and OpenRules
OpenRules Release 7.0.1 provides a sampling and detailed tutorial of how to add an OpenRules-based service to the popular Spring framework. The new tutorial “Developing Decision Microservices with Spring Boot and OpenRules” in a step-by-step manner explains how to convert OpenRules-based decision projects into Decision Microservices and to deploy them on any server or a cloud environment supported by Spring. Read it and try to run the demo microservice “GreetingService” by downloading the new workspace called “openrules.spring” now included in the evaluation version.

New OpenRules Release 6.4.1 with DMN Why-Analyzer
“Imagine you had a Why Button handy whenever you encountered some disconnect in day-to-day business operations. Hit the Why Button and presto – answers appear in the form of relevant business rules” – Ron Ross, 2013
The release OpenRules Release 6.4.1 introduces a new add-on called “Why-Analyzer for Decision Modeling” that provides such a Why Button for decision models created in accordance with the DMN standard. Actually it is much more than just a button but rather a graphical interface that allows business analysts to analyze the results produced by their decision models using their own test cases created directly in Excel. See a brief video and try it yourself without any downloads from here. There are several more product improvements described in the release notes. You may download the latest release and try your own decision models with OpenRules Why-Analyzer. Continue reading
Enhanced Live Catalogs at DMCommunity.org
A few years ago, I wrote a web application that allowed professional communities to support Live Catalogs of different software tools. The “live” means that a product catalog is automatically updated whenever the profiles of products included into the catalog are added or updated by their authors. Continue reading
Building a Maintainable Product Catalogue with OpenRules Dialog
This year I will chair a workshop “CPSOLVERS-2013” at the major Constraint Programming conference “CP 2013“. Preparing the workshop, we’ve decided to create an industrial overview of all supported constraint solvers currently available to business application developers. Continue reading
