Introduction to the FICO Xpress Insight 5 Installation Guide

FICO® Xpress Insight 5 is used by solution developers to run optimization problems written as a Mosel or LP/MPS file that are submitted through a REST API and monitored thorough the app, to enable users to execute optimization models and perform in-depth what-if analysis.

Concepts and Components

Xpress Insight 5 combines a set of components to enable a user to submit optimization and infeasibility problems by utilizing several logical concepts and data artifacts.

FICO® Xpress is a pre-requisite of FICO® Xpress Insight 5. Xpress provides access to optimization algorithms and technologies used to solve linear, mixed integer and non-linear problems. Before you begin, ensure that you have the correct version of Xpress for the version of Xpress Insight that you are installing. Xpress Insight 5 uses Xpress 8.10.

Xpress Insight 5 can be installed in one of two configurations:
  • Development mode or Production mode. Development mode allows local accounts and should only be used while evaluating Xpress Insight 5 or very small-scale development. SAML integration (specifically OKTA) is available in development mode and FICO recommends using SAML.
  • Production mode should be used for operational installations. It utilizes SAML identity verification and disables local accounts. All user administration functions are handled though the OKTA system capabilities.

Xpress Insight 5 stores the operational data that it generates using either the native file system associated with your installed operating system, or a customer installation of MySQL v5.7 or above. File system storage is sufficient for use during development, but production deployments should use a database.

MySQL integration is Not Available in the BETA Release .

Logical concepts include:
  • Insight Worker: Workers are the machines that ultimately run scenarios. Each worker can run on a separate machine, and you can configure as many as are required subject to licensing arrangements.
  • Execution Services: These are used by Xpress Insight to execute scenarios when mapped to execution workers. An execution service represents a logical partition of its associated worker's processing capabilities.
  • Execution Service Mappings: Provide links between the defined execution services and their associated execution workers.
  • Execution Modes: A mechanism that enables scenario developers to specify their likely processing needs and are usually expressed as model annotations.
Key data artifact:
  • Model: The optimization model itself, defining a set of input entities to receive scenario data and a set of result entities that are populated with the optimization solution. A solution is a set of values representing the decisions identified by the optimization process, together with other data synthesized from these values. It contains a set of constraints that place restrictions on what can be valid solutions.
