Information : Server-Based Computing Using Thin Clients/Citrix Implementation
Raytheon IDS implemented a server-based computing solution using thin clients to improve Shop Floor Data Manager operations. Citrix is cost-effective, saves time, and extends the life span of hardware.
Raytheon Integrated Defense Systems’ (IDS’) shop floor was showing its age. Hundreds of desktop PCs could no longer meet the demands and needs placed on them by larger application programs and operating systems. The cost and time needed to update and service desktop PCs that are part of the Shop Floor Data Management (SFDM) System was growing exponentially.
To address the problems associated with SFDM computers, Raytheon implemented server-based computing using thin client solution Citrix, a server-based architecture where Raytheon’s applications are centrally stored and managed on shared servers. Raytheon now uses Citrix to run SFDM systems to automate workflow and data capture of assembly and work package functions and operations. Shop floor works now use Citrix to access applications via a Wyse Winterm thin client instead of a full-featured PC (Figure 3-2).
The benefits of using server-based computing were immediate and include:
One device, one password, and one operator to access multiple programs Central management of virus protection, application version control, license management, and system administration.
Built-in fault tolerance and load balancing
Reduced site operations incident calls, with rapid resolution to those that do occur
Slow computer boot-up has been eliminated and improved application processing time
New software upgrades are installed once at the server level, eliminating the need to visit each client station
Citrix thin client is a cost-effective system that can be installed in minutes versus hours. At one- third the cost of a PC, thin client will enable Raytheon to realize significant future savings both financially and in reduced man-hour installation time.
