IBM ILOG CPLEX Optimization Studio vs. SAP Crystal

It is well suited for solving large-sized, mixed-integer, and integer programming problems. Now, the new version supports for Multi-Objective optimization along with some new algorithms such as Benders Decomposition. It is less appropriate for quadratic programming problems where the objective function is the product of multiple variables. However, it's very easy to code any problem.

Generation of templated reports is the strong suit of SAP Crystal. Allows users to change formats in templates bases on requirement with minimal effort. Automated report delivery requires the user to be aware of sql which cannot be expected from all users. Should support more document export formats and improve the UI for SAP B1 Users

• Crystal Reports allows us to create a consistent template for all of our reports.
• Crystal Reports and Server allows us to house a repository for all of our reports to make them easy to find and update when necessary.
• Crystal Reports can connect to a wide variety of data sources.
• Crystal Reports can be a little daunting when first implementing. There are a lot of nuances in learning how to truly master this software and it can be frustrating at times.

• Data handling from different sources like Note Pad, etc.
• Large size of MILP problems.
• Various parameters to set.

• The export of reports to Excel is very cumbersome and the results are difficult to format.
• The design of reports and the graphical features (e.g. charts) feel quite rigid.
• The learning curve for a non-programmer is incredibly steep, making Crystal a specialty tool.

We have been using this product for so many years and it has truly become a cornerstone to our business processes when it comes to developing and distributing information via reports. We currently have over 500 reports developed to date over about 30 systems and that will continue to grow as user needs change.

It's nice to use and with good optimization.

Crystal is very robust, but not always easy to use. It create wonderful looking reports, and so deserves a high rating. However, I have to take a couple of points off for the simple fact that I cannot hand it to a user and expect them to be able to do development with it.

Honestly, to say, I never contacted CPLEX but used its forum to know/clarify any issues I faced.

The support community can be difficult to navigate. I've also run into issues with my login. The SAP system has a bizarre mechanism for validating users that requires users to have what is called an S-ID. A basic ID may not give you access to all the features in the portal. The limitation may include not being able to perform a simple task like downloading patches and updates. This isn't a big deal for single user license but for teams it can be a pain.

Trainer was patient and thorough in going through the basics and willing to answer questions by email after the initial training

Just like any other implementation: When designing the differing reports, get end users' input, make sure to design the reports so that they display the information that the company requires, in the best and clearest way possible.

Test, test, test, revise when needed, and, particularly, do sufficient training so users are comfortable using Crystal Reports!

IBM CPLEX Optimization Studio covers wide range of problems in comparison to Gurobi and also offers a number of visualization tools for results analysis. It has better customization and parameter tuning options in comparison to Gurobi. It offers various API integrations such as Python, Java and C++ which is not the case with Gurobi.

Crystal reports is useful in case we want to import data from data base . We can write queries in it but Google Charts require to be implemented in our application using code so crystal reports is better than Google Charts.

• Faster computation leading to better internal customer relations
• Able to solve high variable problems with ease
• Anomaly detection became easier within business

• It is a decent buy for specific departments in terms of reporting capabilities but updates and cost (frequent) demands are higher with the benefits offered.
• So long as the requirements are not ever changing, with scheduling functionality, it's a handsome tool.
